New Year Green Resolutions - Use E15 petrol only

My Renault Megan 2.0 litre engine is warranteed to takes up to a 15% blend of ethanol and gasoline. The French have been driving on blended petrol and biodiesel/diesel blends for years. There is an independent petrol station in Randwick selling an E15 blend under the name of ULP. My New Year Resolution is to merge the two happy co-incidences and give them my custom.

The rewards are many. The ethanol is derived from Queensland grown sugarcane so this helps reduce Australia's reliance on foreign oil infrastructure. It gives the Megane more punch when needed and helps reduce greenhouse gas emissions as this report from 2003 shows.

Engine performance and total emissions are both improved by the addition of ethanol to gasoline. The clean burning nature of ethanol allows you to capture more of the work from the fossil portion of the gasoline, which compensates largely for the lower energy content of ethanol itself. In a 10 per cent blend (E10), all other things being held the same, you might get a zero to 2.7 per cent loss in mileage (kilometres per litre).

Another performance benefit from ethanol is its high octane addition to fuel. Of all the commercially viable octane enhancers possible, nothing delivers more punch than ethanol. The populace still feels the ill effects of the tons of poisonous lead that were spewed into urban environments because of the poor decision to accept lead over ethanol as the octane additive of choice.

But will I really achieve any good? Choice Magazine weighs up the pros and cons:

Ethanol-blended petrol has advantages and disadvantages for the environment over normal petrol ? the extent of most of them depends on factors such as the percentage of the blend, the engine type and how the ethanol was produced:

• A 10% blend generally reduces the car?s emissions of carbon monoxide, hydrocarbons, some carcinogens such as benzene and toluene and ? in some circumstances ? the greenhouse gas carbon dioxide. However, due to the government subsidy, any reduction of carbon dioxide emissions comes at a very high price compared to other initiatives.
• Ethanol increases the petrol?s volatility, and therefore the amount of evaporative emissions of volatile organic compounds, which can contribute to global warming and the formation of ground-level ozone (summer smog). This can be avoided by changing the volatility of the petrol used for blending.
• There are higher emissions of carcinogenic aldehydes (such as formaldehyde and acetaldehyde) and ? in most cases ? of oxides of nitrogen.
• Overall, there seems to be little benefit for urban air quality or greenhouse gas emissions resulting from the use of ethanol-blended petrol. However, as ethanol is produced from agricultural products or waste, it?s a renewable energy source.

In the end analysis, if 15% of the fuel I am using is made from carbons that have been sucked out of the atmosphere rather than the ground that is an overall environmental gain for me. I'll just have to wait till 2007 to order my solar car.

2005 wins for science

A Concerned Scientist looks back at some wins for science and and conservation in the assult by ID activists, and big oil's search for big deposits. Sustainable Energy 2005 Round-up:

2005 saw it's drastic ups and downs in gas and energy prices, with the threat of Peak Oil to our economy looming, our energy infrastructure remaining a troublesome national security issue, and evidence abounding for the acceleration of global warming and climate change. But renewable energy has seen great progress this last year as well, with numerous local and state initiatives proposed and implemented (even if Bush continues to stand in the way), further R on improving energy and transportation technologies, and a nascent community of private companies taking steps towards a sustainable future (e.g. GE, BP).

At the top of the list are Governor Schwarzenegger's (R-CA) Million Solar Roofs Initiative, the Northeast's Regional Greenhouse Gas Initiative, and a series of other regional projects encouraging Kyoto-like emissions reduction targets. Given the threat posed by a collapse following contraction of our petroleum-based economy, expanding alternative fuels and energies is a must. Significant obstacles remain, however: most solar panels still require expensive highly purified silicon; wind farms are objected to as unsightly and threaten migratory birds/bats; biofuels would take more energy to produce than they would supply and don't represent a permanent solution to carbon emissions; hydrogen fuel cells still require expensive platinum and other components, and hydrogen production/distribution schemes remain unsatisfactory; nuclear power has gotten safer in the last 30 years, but still has questions of waste disposal that need addressing; and coal does nothing to address carbon emissions, although mercury and other pollutants have been cleaned up substantially.

Still, we must laud the initiatives and projects that've seen notable progress this year, as we head towards Peak Oil.

I would add the growing realisation that GM seeds have lower yields than unmodified seeds to be a win. Modifying seeds genetically so they can help sell more chemical fertiliser (at the expense of the environment) does not deserve to be a sustainable business.

It's biodiversity, or bust baby!

EPA sets ethanol content standard in petrol.

The US EPA has finally acknowledged that ethanol blended petrol burns cleaner and mandated a 2.78% blend of ethanol and petroleum gasoline to be sold. The higher octane ethanol burns more cleanly in a combustion engine reducing harmful emissions.

The Environmental Protection Agency said on Wednesday it expects the US oil industry will meet the EPA's new standard that requires 2.78 percent of gasoline sold next year to be renewable fuel, such as ethanol.

Congress passed a broad energy bill which was signed into law in August, requiring ethanol production almost to double to 7.5 billion gallons a year by 2012 to help make gasoline burn cleaner, stretch available US motor fuel supplies and reduce petroleum imports.

This is progress. Although the pace has been set by those Brazilians who use up to 25% ethanol blended petrol without any problems the US is the largest consumer of fuel in the world with the Energy Department forecasting that 141.6 billion gallons of gasoline will be sold next year in the US market. The legislation also encompases biodiesel and other renewable fuels.

Dinosaurs cooked by global warming

Fresh fossil leaves analysis shows there was a sudden and dramatic rise in carbon dioxide in the Earth's atmosphere 65 million years ago. It's what killed the dinosaurs, say researchers. C02 was injected into the atmosphere in vast amounts by the impact of an asteroid striking CO2 rich limestone rock and the ensuing blistering heatwave that followed raised global temperatures by as much as 7.5 Celsius making it impossible for the ancient reptiles and countless other lifeforms to survive. CO2 levels were estimsted to be four to five times higher for 10,000 years after the impact

The researchers from the University of Sheffield, UK, and Southwest Texas State University and Pennsylvania State University, US, studied the fossilised pores of leaf of gingkoes and ferns that grew around the time of the dinosaurs' demise. The number of carbon dioxide-absorbing pores in the fossils reflects the amount of carbon dioxide in the air: the fewer the pores, the more carbon dioxide.

By using computer simulations and doing real experiments on plants, the scientists can show there was a sudden, five-fold increase in CO2 at the end of the Cretaceous.

This can only be explained, they believe, by the sudden vaporisation of between 6,400 and 13,000 billion tonnes of carbon - a substantial component of the limestone rocks that lined the shallow sea that existed at Chicxulub 65 million years ago.

2005's Scientific Milestones

With a US court ruling Intelligent Design as religion dressed up as science here's a review of how well science served us in 2005.

With this in mind, the journal of the American Association for the Advancement of Science has declared discoveries about evolution the 2005 winner of its annual list of top 10 breakthroughs.

"Today evolution is the foundation of all biology, so basic and all-pervasive that scientists sometimes take its importance for granted," Science concludes.

Huge numbers of studies in this field are generated annually. But "2005 stands out as a banner year for uncovering the intricacies of how evolution actually proceeds", it says.

The genetic code of a chimpanzee named Clint was deciphered this year, for example, revealing that 96 per cent of our DNA is identical to his.

Other top 10 scientific breakthroughs include discoveries in how miswiring of the brain occurs, climate change events, earth's origins, nuclear fusion, cellular biology, the nature of neutron stars, secrets of flowering, cell communication, voyages to the planets.

It is hugely impressive that mankind has been to the outer rings of Saturn, and landed the European spacecraft Huygens on Titan to find a world where liquid methane rains down to create valleys and lakes. And yet humbling to know that our DNA is 96% match with that of chimpanzee-kind. It is impossible not to admire the minds that discovered that our cells communicate with each other using a chemical network as complex as the Internet, and hard not to feel despair for human beings who ignore the signs and pace of global warming.

My wish for 2006 is a greater respect for all science but particularly the science of climate change, and dramatically greater awarness and responsiveness to global warming. I feel the US Federal Court Judgement to keep religion out of the science class upholds a respect for science, much needed to convice the world to avert dramatic climatic change.

Flat Earth Theory #1: Hotter sun causes global warming naturally.

If global warming is man-made then ignorance must be a root problem, and I will be contesting it in my Flat Earth Theory series.

There are clearly vested interests who fight hard to obscure the fact that the fossil fuel emissions increase the onset of climate change (we just have to see how the US, Saudi Arabia and Australia stonewalled at the Montreal UN Climate Change Conference), and I always find it fascinating how their spin finds itself into the mouths of the general public.

Glitch, a regular (possibly my only one) has forwarded the theory that increased solar activity is the driver behind the global warming we observe:

I'm sorry - but I believe that the earth's temp is PRIMARILY driven by variations in the Sun's output.

If EVERY CAR/TRUCK/PLANE/ELECTRIC POWER PLANT was turned off TODAY, I do not believe it would change the 'global climate' - sea levels will go up and go down...and there is NOTHING humanity can do about it.

Glitch has a good point, the sun is indeed the greatest influence on the earth's temperature, but that is not the whole story. I will try to illustrate with an example. If I go sunbathing, the sun will initially be the greatest influence on my body temperature, which would rise. So far Glitch's argument is supported in this example. But then my pores would open in response to my body's increased temperature and I would sweat. This sweating will cause evaporation thus cooling down my body and keeping it at an average temperature of around 37 degrees Celsius. The biological name for a mechanism for maintaining equilibrium is called homeostasis. Without a homestatic mechanism for cooling I would just heat up, cook and die.

If we take the view that the earth is an organism of sorts, as in the Gaia theory of James E Lovelock, then we can attribute Gaia with a homeostatic mechanism that keeps her temperature at an equilibrium that sustains life. Gaia's temperature chart for the last 1800 years (Mann, et al, 2003) indicates that this is indeed what happens.

One of the main drivers for this mechanism is called albedo, or the reflectivity of the earths surface. The earth, on average, reflects 31% of the sun's heat back into space, keeping it cool, and can be described as having an albedo of .31 while snow and ice has an albedo of .9 and oceans have an albedo of .1, or 10%.

As an aside, it was Leonardo da Vinci who first explained, almost exactly 500 years ago, that the earth reflects the rays of the sun in his Codex Leistercer.

So now you can see why healthy artic and antartic ice and snow belts are vitally important to regulating the earth's temperature. Where do the greenhouse gases that Glitch referred to fit into the picture? Well, they trap the heat that is reflected. If I may return to my previous example of sunbathing. Many underarm deodourants work by closing the pores of the skin, preventing sweating. Now if I was to cover my body with such a deodourant prior to sunbathing, I would be disabling my cooling mechanism and would thus overheat and suffer sunstroke. By not reversing the rate at which we put CO2 in the atmosphere, humanity is collectively doing pretty much the same thing to Gaia; we are disabling her cooling mechanism.

Yes it is a fact that there has been an increase in solar activity:

Since the middle of the last century, the Sun is in a phase of unusually high activity, as indicated by frequent occurrences of sunspots, gas eruptions, and radiation storms. Researchers at the Max Planck Institute for Solar System Research (MPS) in Katlenburg-Lindau (Germany) and at the University of Oulu (Finland) have come to this conclusion after they have succeeded in reconstructing the solar activity based on the sunspot frequency since 850 AD.

But recent studies by German and Finnish research teams conclude that this is just one cause:

The influence of the Sun on the Earth is seen increasingly as one cause of the observed global warming since 1900, along with the emission of the greenhouse gas, carbon dioxide, from the combustion of coal, gas, and oil. "Just how large this role is, must still be investigated, since, according to our latest knowledge on the variations of the solar magnetic field, the significant increase in the Earth?s temperature since 1980 is indeed to be ascribed to the greenhouse effect caused by carbon dioxide," says Prof. Sami K. Solanki, solar physicist and director at the Max Planck Institute for Solar System Research.

In summary, Glitch, it all comes down enhancing our collective albedo. ;)

World's hottest year yet.

2005 is Australia's hottest year recorded and may be the planet's warmest for thousands of years. Add to that the extreme weather events we have been experiencing and you end up wondering how anyone could doubt global warming is occurring at an alarming rate, whether they believe it is anthropogenic or not.

Other points in the SMH article include:

Michael Coughlan of the Australian Bureau of Meteorology said 2005 and 1998 were vying to be the hottest years on record globally, with only two weeks of measurements to be made. "Nineteen ninety-eight has its nose in front, but the race is not over yet."

Dr Coughlan said the record warmth in 1998 was helped along by a strong El Nino event - a warming of the equatorial waters in the Pacific Ocean occurring every three to seven years that tends to increase global temperatures. "The 2005 warmth is remarkable for the fact that it occurred in the absence of an El Nino event," he said.

Will Steffen, director of the Centre for Resource and Environmental Studies at the Australian National University, said temperatures had risen sharply in the past few decades due to increasing greenhouse gas emissions.

"The last time the Earth was this warm was about 5000 or 6000 years ago."

...

In 1998 the average global surface temperature was 0.54 degrees above the 30-year annual average for the years 1961 to 1990. This year's temperature has so far been 0.48 degrees above the average. Final figures will be released in February.

It's going to be a long hot summer.

Nice one Ma'am.

When the British (and Australian ... go figure?) Queen decides that it is her turn to do something about reducing her energy footprint, she shows us how it is done:

London: The Queen is to go green after full planning permission was granted to run Windsor Castle on hydro-electric power.
The $2.3 million, four-turbine plant will be built at Romney Weir on the River Thames.

Charles has obviously been chewing on HRH's ear. His green credentials go way back.

The 56-year-old supported organic farming as far back as 1984, long before it became a mass consumer issue and his vociferous belief in conservation has often been ahead of the times.

The Queen has her own army of devoted fans, and her going green in this way sends them a powerfull message.

Buckingham Palace said the royal household was pleased the project had been approved. "We're constantly looking at ways of saving energy," a spokesman for the Queen said. "We use energy-efficient lightbulbs at Buckingham Palace and recycle 99 per cent of green waste."
The electricity from the new plant will be fed straight into the Queen's Berkshire castle and not into the local grid. The plant will be the biggest of its kind in southern England.

HRH gets my vote, even though she does not run.

Study: Those bullied by life bully nature

The rich don't chop down trees because watching the jungle reclaim their upsized backyards appeases guilt over having too much power? The poor take their powerlessness out by dominating nature with the backyard chainsaw?

Wealthy Sydney professionals live in leafy North Shore suburbs because the trees on the streets make them feel comfortable with their power in society, according to a new study.

This week's Institute of Australian Geographers conference will hear that tree cover in city suburbs is closely related to authority and alienation. Jamie Kirkpatrick, a geographer at the University of Tasmania, thinks less affluent urban dwellers often feel powerless in their work and personal lives, so they exert authority by removing the flora around their homes.

Middle-class home owners, on the other hand, want a break from being in charge, and enjoy returning to a wilder, more out-of-control environment.

Bizzare behaviour ... I usually find that getting a jolly good flogging from Mistress Amanda to be a surefire salve when I start fretting about the heady power (courtesy of this blog) that I wield.

Interesting theory, but I don't think this applies where a tree comes between a property owner and their harbour view. The Sun Herald reported on 29/10/2000 that

Professional hit men target harbour trees
WEALTHY residents in Sydney's eastern suburbs are allegedly using "hit men" to poison trees and enhance their harbour views. One of Australia's wealthiest suburbs, Point Piper, has had 41 protected trees poisoned, lopped, or removed without permission over the past 18 months.

This must have galvanised some sort of action because there has been only one newspaper report on the subject in the Fairfax press since:

Site Review: Earth Day's My Footprint

The Ecological Footprint Quiz (©Redefining Progress) seeks to give you its best answer to the question of how much "nature" your lifestyle requires?

The Ecological Footprint Quiz estimates how much productive land and water you need to support what you use and what you discard. After answering 15 easy questions you'll be able to compare your Ecological Footprint to what other people use and to what is available on this planet.

The concept behind an ecological footprint has been around for at least a millennium and a half; back in 5th century Anglo-Saxon England environmental footprints were known as 'hides' and 'hundreds'. A hide describes the amount of arable land it takes to feed a single family for a year, and a hundred describes how much land it would take to feed a hundred families.

I digress. I answered the quiz questions. They break down your Ecological Footprint into Food, Goods, Shelter and Mobility footprints. Press the button and Bob's your uncle:

CATEGORY --------------------- GLOBAL HECTARES
FOOD ........................................................ 3.1
MOBILITY ................................................. 1.9
SHELTER ................................................... 0.9
GOODS/SERVICES ....................................... 2.9
TOTAL FOOTPRINT ..................................... 8.8

8.8 hectares distributed globally in little furlongs, plots and parcels - so I'm not doing too badly, right?

IN COMPARISON, THE AVERAGE ECOLOGICAL FOOTPRINT IN YOUR COUNTRY (Australia) IS 7.6 GLOBAL HECTARES PER PERSON.

WORLDWIDE, THERE EXIST 1.8 BIOLOGICALLY PRODUCTIVE GLOBAL HECTARES PER PERSON.

IF EVERYONE LIVED LIKE YOU, WE WOULD NEED 4.9 PLANETS.

Alright already! I hear you. It's not enough that they admonish me, they graphically drive home the point by whipping up 5.9 planets side by side. So? At least I have room to improve. Multiple global room it seems.

My Food Footprint has the biggest global hectarage (3.1) of all my categories. That's because I eat a lot of meat and dairy. Love it. I am a southern hemisphere born and bred carnivore who emigrated from one barbecue culture to another. I didn't spend evolution clawing my way up the food chain just to eat carrots and pumpkin forever. Nevertheless there are a few sound reasons to cut back on meat and dairy, including the looking after your heart and bowel. I wonder, how many global hectares could I cut back on if:

I cut back on rate of meat and dairy consumption to something more healthy, from Almost always to Often

A. How often do you eat animal based products? (beef, pork, chicken, fish, eggs, dairy products)

1. Never (vegan)
2. Infrequently (no meat, and eggs/dairy a few times a week) (strict
   vegetarian)
3. Occasionally (no meat or occasional meat, but eggs/dairy almost daily)
4. Often (meat once or twice a week)
5. Very often (meat daily)
6. Almost always (meat and eggs/dairy in almost every meal)

and conscienciously cut back on processed and packaged food, especially that from far away and thus reducing the impact of transportation?

B. How much of the food that you eat is processed, packaged and imported?

1. Most of the food I eat is processed, packaged, and from far away
2. Three quarters
3. Half
4. One quarter
5. Very little.
6. Most of the food I eat is unprocessed, unpackaged and locally grown.

Well my Food Footprint reduced a whole global hectare, from 3.1 to 0 2.1. And this seemed to have a positive effect on my Mobility Footprint, down from 1.9 to 1.8 (please explain?), and my Goods/Services Footprint, down from 2.9 to 2.8. I guess here I generate less landfill. Best of all I bring my Total Footprint in line with the national average of 7.6, a full 1.2 global hectares improvement. I am instantly rewarded from my aspiring good global citizenship by knowing that:

IF EVERYONE LIVED LIKE YOU, WE WOULD NEED 4.2 PLANETS TO LIVE ON

I rate Ecological Footprint Quiz 4.9 planets out of a possible 5 (I'm taking .1 off for being rude) assuming it employs an accurate methodology in its calculations. It does get one thinking, and potentially acting. You could find yourself involved in an email campaign to your local council to get them to consider commissioning an Ecological Footprint index for the community from the good people at Redefining Progress.

Finally some rain where it counts.

It must be Christmas. Finally, finally some rain has fallen in the Warragamba Dam catchment area, despite the fact that NSW has just had the wettest spring since 2000 with average to above average falls. Sydneysiders, long used to water restrictions brought on by the drought and the many false promises of rain falling outside the catchment will not know what to do with themselves.

Yet there is not enough reason to get light headed and wash your car though; this increase in dam levels will only supply us with water for two weeks. If Sydney's catchment area gets no more rain, the dam will run dry in two years.

The reason why so much rainfall misses the catchment area of the Nattai River, the river that gives Sydney 80% of it's water, has been hypothesised by a Macquarie University physical geography professor to be a result of extensive clearing of natural vegetation as great swathes of suburbia are laid down. Using computer modeling Professor Andy Pitman determined that:

the vegetation loss had changed the dynamics of atmospheric convection, which is a key to forming many thunderstorms that strike Sydney on summer days. Without the vegetation, sea breezes could sweep further inland, changing the location where they collided with winds blowing from the south-west.

In related good news: The Australian Bureau of Meteorology climate officer Mike De Salis says the El Nino ocean pattern is subsiding, leading to wetter conditions for eastern Australia. Forecasters predict the drought is finally coming to an end.

Chinese demand for greenhouse energy will not abate.

Trying to slow global warming without limiting economic growth is one of the central problems facing delegates in Montreal this week at the first climate change conference since the Kyoto Protocol came into effect in February this year. This is not helped when the two largest emitters, both put prosperity ahead of environmental concerns, and both emphasise efficiency measures of greenhouse gas production rather than the absolute amounts.

Mr Sun Guoshun, director of the Department of Treaty and Law at the Chinese Ministry of Foreign Affairs said China had set a goal of increasing energy efficiency by 20 per cent between 2006 and 2010, while President George Bush aims to reduce greenhouse gas production by 18 per cent as measured against gross domestic product.

Europe's water heater is slowing down.

The irony of Global Warming becoming Global Freezing gets more real with the discovery that the ocean currents which circulate heat around the Atlantic have slowed down by about a third.

Europe's relatively mild climate depends on a system of currents known as the North Atlantic heat conveyor.

Warm surface waters from the tropics flow northwards in the Gulf Stream, releasing heat to the atmosphere, before sinking and returning southwards as a deep cold current. Global warming is forecast to disrupt this system by injecting fresh water into the Atlantic near the North Pole as rain increases and the Greenland ice cap melts. A slowdown in the heat conveyor could cause European temperatures to drop by 4 degrees.

In a study published today in the journal Nature, British researchers at the National Oceanographic Centre in Southampton surveyed the strength of currents at various depths in the subtropics.

They found the circulation system had weakened overall by 30 per cent since 1957, with a 50 per cent reduction in the amount of cold deep water flowing southwards and a 50 per cent increase in the amount of water that never leaves the subtropics. "The implications of these observations are considerable," Professor Quadfasel said. In the past, temperatures have dropped by up to 10 degrees in a decade. This happened after a huge amount of fresh water from melting ice sheets, which had been caught behind a natural dam, suddenly flooded the North Atlantic and shut down the heat conveyor about 8500 years ago.

If global warming caused a similar shutdown, this would have "devastating effects on socio-economic conditions in the countries bordering the eastern North Atlantic," Professor Quadfasel said.

A CSIRO scientist, Stephen Rintoul, said it was premature to blame the weakening of the North Atlantic heat conveyor on global warming.

National call to combat climate change invoked by new state premier

Whether he is for real or spinning, the guy with the state's top job is making a big call to Kyoto Protocol cynic and Australian Prime Minister, John Howard.

Recently I wrote to the Prime Minister requesting him to convene a three-day national summit in the first half of next year on climate change and greenhouse gas emissions trading. The NSW Government believes a market-based approach is needed to tackle the problem of carbon emissions. The NSW Greenhouse Gas Abatement Scheme introduced in 2003 was the world's first mandatory emissions trading scheme. Earlier this year we extended the scheme from 2012 to 2020 and beyond until a national emissions trading scheme is established.

Such a scheme would provide greater business and environmental certainty for Australia as carbon-dependent economies are forced to make significant emissions reductions to contribute to the abatement of global climate change. There has been a significant shift in the business sector's opinion and also strong support from conservationists. The Howard Government, however, will not participate in this vital work

As proposed to the Prime Minister, such a scheme should be the focus for the national summit which could also discuss the promotion of clean technologies, energy efficiencies and the use of taxation policies to drive down emissions. The national summit should include community members, key business sector representatives, environment groups, and prominent scientists with expertise in climate change.

I have also written to the other premiers and chief ministers who I am sure will give the summit their support. I have suggested to my colleagues that if the Prime Minister does not exercise his national leadership responsibilities and convene this summit then the states and territories should do it themselves. NSW will continue working on new approaches. Today I am releasing the Government's NSW Greenhouse Plan which comes with a $24 million funding package, including grants to promote the adoption of emissions reduction technologies. We will also commit significant funding to education about the causes and risks of climate change and for projects that promote innovation, carbon sequestration and emissions trading.

Our commitment to reducing greenhouse gas emissions is also evident from the $100 million we will spend to minimise the impact of our desalination plant. This will reduce the emissions impact by 50 per cent through renewable energy sources such as gas or wind, tree-planting programs and use of abatement certificates.

These are solid commitments to tackle greenhouse gas emissions. It is time for the Prime Minister to exercise national leadership on the major threat that climate change poses and convene this long overdue national summit to chart Australia's way forward.

Morris Iemma is the Premier of NSW.

Well and good Iemma, and probably very clever, but you lead a government that messed with my route to work with your Cross City Tunnel. Turning the CBD and neighbouring suburbs of the state's capital city in into a concrete corral designed to funnel through the tolling tunnel can't be doing much to reduce emissions. I am not blaming you, just your government. Let's just see how effective you are with Howard and the other state premiers.

I am not convinced that we need a desalination plant, bottled electricity as it was once famously called by your predecessor. If it is another PPP, we need that like we need a hole in our city.

# 3 link added: Greenfleet

Real climate change demands real action. Plant a tree or three. Seriously. This will sink enough CO2 to neutralise up to 1 year of your car's emissions. Or pay Greenfleet to plant trees for you. Since 1997, Greenfleet has planted more than two million native Australian trees on behalf of individual motorists and organisations.

Greenfleet's policy is to plant trees to create forests in areas of environmental concern, putting back the mix of native species that had been there originally. The trees are propagated from seed collected in the local area to provide maximum ecological benefits - reducing salinity and soil erosion, and providing essential habitat for native species. The majority of our plantings occur in winter because the rains help to get the trees off to a good start.

It is expected that Greenfleet will continue to grow quickly over the next few years. Currently they plant trees in Victoria, ACT, Queensland, New South Wales, South Australia and Western Australia (they are currently seeking sites in Tasmania for 2006). One of their priorities is to become ?Kyoto compliant', so that they have the ability to measure the carbon uptake from our trees to emerging international standards.

Global warming not all hot air

New artic ice core studies reveal CO2 at highest levels in 650,000 years, and six ice ages. We experience atmospheric CO2 levels of 27% higher than past peaks periods.

The European team's leader, Thomas Stocker, of the University of Bern, said the research showed that "the timescales on which humans have changed the composition of the atmosphere [are]extremely short compared to the natural time cycles of the climate system".

Carbon dioxide levels are now 380 parts per million, compared with previous peaks of below about 300 parts per million.

The ice core study, published in yesterday's issue of Science, confirmed that temperatures have been closely tied to greenhouse gas levels throughout this period in a way that climate modellers had predicted.

Three of the previous six interglacial periods were also found to have lasted nearly 30,000 years, much longer than the 10,000 years or more of recent interglacial periods. This meant, fortunately, that another ice age was not due for 15,000 years, the researchers said.

In other news new research shows that sea levels have been rising by 1mm per year to around 1850, after which they started rising by 2mm per year.

Great, bleach barrier reef algae!

Hopeful evidence that reefs may have some resistance to climate change and the feared 'coral bleaching' is emerging from the Australian Institute of Marine Science and CRC Reef Research Centre.

Scientists believe corals may be able to protect themselves from devastating bleaching events after discovering some can adapt to climate change.

The find, described by Ray Berkelmans as "tremendously exciting", comes amid predictions that the Great Barrier Reef could be wiped out by the end of the century because of rising water temperatures.

The good scientist goes on to say his studies had found coral could adapt to climate change by using a type of algae to become thermally tolerant.

"Through an extensive transplant experiment and also through laboratory temperature stressing experiments we were able to determine that, at least for the species that we were looking at, under some conditions the corals were able to take on a new type of algae into their system," he said yesterday.

"There are different types of algae that it can associate with and when it associates with a particular type called D, it becomes more thermally tolerant. That's a tremendously exciting find. Up until recently we weren't sure that corals could adapt at all.

"We found instances where individual corals change the dominant zooxanthellae (algal partner) type from type C to D after a major stress event," he said. Type C is found in more than 95 per cent of the reef.

"It's evolution within the lifespan of an individual coral, and that's the exciting part."

Dr Berkelmans said the find gave scope for optimism that corals could survive future bleaching events, but some questions remained: "We don't know which species; we don't know where; we don't know why."

And so might some of the enormous biomass that the world's coral reefs support, recycling CO2 through the carbon cycle and having a moderating effect on the rate of climate change.

Mother Earth important as unborn child: Aussie Bishops

Fresh from debunking Intelligent Design, Australian Catholic leaders are striking another blow for common sense:

Australia's 5 million Catholics were as morally bound to combat the loss of biodiversity as they were to protect the rights of the unborn child, according to a landmark statement by the church's bishops that calls for Australia to cap greenhouse emissions.

The nation's 30 Catholic bishops said ratifying the Kyoto Protocol was the least that Australia could do to continue to "support international structures that help reduce global warming".

Their extraordinary statement on climate change points to a converging partnership between church leaders, environmentalists and scientists, giving moral force to public campaigns to win environmental safeguards. It forms part of a national church strategy to mobilise Australian Catholics to face the changes required to tackle global climate change.

As always the Anglicans are taking things one step further.

In July, a key international body of the Anglican Church declared the wilful destruction of the environment to be a sin.

Getting back to the Catholic Bishops, these guys have a plan as well as a prayer.

A critical part of the solution was in the development of alternatives to fossil fuels.

"As pastors of more than a quarter of the Australian population, we urge Catholics as a matter of conscience to co-operate in facing global warming as one of the major issues of our time, and take roles of responsibility proper to them."

The scientist and author Tim Flannery applauded the bishops' statement, saying it was immensely helpful to furthering the debate on climate change and mobilising individuals to change their lifestyle.

"The debate about climate change is not a debate between left and right, religious and non-religious. It's about holding onto the old economy, on one hand, or moving forward to better our future."

The church's position paper was presented by Bishop Christopher Toohey last night at a climate change conference hosted by Catholic Earthcare Australia.

Copies will be sent to more than 4000 parishes, schools, religious congregations and church agencies.

It will be followed by an updated audit which urges them to switch to more sustainable practices, including use of gas or solar heating and green electricity, grey water recycling systems, car pooling and ethical investment policy for savings.

Australia 23% increase in emissions over 13 years

A report prepared by the Bonn-based United Nations Climate Change secretariat and released this week ahead of the international climate conference in Montreal later this month warned that the western world was losing its grip on the climate change problem.

The report, covering the period between 1990 and 2003, found Australia's greenhouse gas emissions had risen 23.3 per cent on 1990 levels.

I believe Australia has the biggest or second biggest ecological footprint per capita, so it's not like we are coming off a low base here.

The Australian Government's target is to limit emissions increases to 108 per cent of 1990 levels over the period 2008-2012.

Yea, right! But what of the oft heard arguement that limiting emissions would limit our GDP? The opposition is testing that claim.

"Given Australia is on track to be having the hottest year on record, it's clear the Howard government is fiddling while Australia is burning," opposition environment spokesman Anthony Albanese said.

"Having acknowledged the threat posed by climate change, the government has to take action to address this crisis."

Mr Albanese said Britain's 13 per cent reduction in its emissions since 1990 had coincided with 38 per cent growth in GDP, proving that good environmental policy could also be good for the economy.

It's not all bad news though.

UN researchers found that overall in the industrialised world, greenhouse gas emissions were down 5.9 per cent in 2003 compared to the 1990 levels.

2005, hottest year on record, almost.

We can't say that 2005 is the hottest Australian year on record. Yet. But it is looking that way:

the 10 months from January to October were the warmest since monthly records began in 1950 and would probably make it the hottest year since annual records began in 1910.

In the first 10 months this year, temperatures were 1.03 degrees celsius above the 30-year average.

This year's was the warmest September for 125 years.

Repeat after me whilst fanning, "global warming is not happening, not happening, not happening".

Saab 9-5 BioPower Flex-Fuel UK launch

From: Jonathan Fry

E85, carbon neutral petrol, has a higher octane rating than unleaded petrol. Saab have engineered an engine that harnesses the higher oxygen content to burn more cleanly, reduce emissions, particulate matter and deliver performance.

Because Saab's turbocharging technology and engine management systems make it possible to take advantage of bioethanol's higher octane rating, an impressive 20 per cent gain in brake horse power (bhp) and 16 per cent growth in torque can be enjoyed when the car runs on E85 compared to when running on regular petrol.

Ethanol, made from renewable biomass such as sugar-cane, sugarbeet, etc., is mixed with 15% unleaded petrol to make E85, which turns out to be the right ratio to achieve carbon neutrality.

Unlike petrol and diesel, the consumption of E85 does not significantly raise atmospheric levels of carbon dioxide (CO2), which is the greenhouse gas that, according to some scientific research, contributes to global warming. This is because the emissions that are released from the combustion of bioethanol whilst driving are cancelled out by the amount of CO2 that is removed from the atmosphere, through the natural photosynthesis process, when the crops for conversion to bioethanol are grown.

Frisky lizards in climate change warning

The blue-tongue lizards of my home state are now mating early as mother nature tell us that the climes are a-changing:

As a result, its behaviour - along with other native flora and fauna - is being catalogued for an ecological database that meteorologists hope will give an insight into climate change and its effect on nature.

Dr Lynda Chambers helped establish the database at Melbourne's Bureau of Meteorology Research Centre after noticing "astounding" behavioural changes.

"Change to plant and animal behaviour is nature's own yardstick," she said today.

"When we see and record ecological changes, it's an indicator of how the climate is changing.

"The Sleepy Lizard is now mating weeks earlier due to the warmer and drier winters.

Dr Chambers' work will be presented during an international conference on greenhouse and climate change at Melbourne from November 14-17. She records changes across the board.

"The fact that so many different species are exhibiting changes is quite astounding."

Amazon source at 36 year low

Key points

• Worst drought in 42 years prompts declaration of State of Emergency in Amazon River delta.
• 1000's of towns and villages cut off from outside world as falling water levels make river unnavigable.
• The level of the tributary Rio Negro, has dropped 12 metres since July to just 16 metres.

Is this linked to global warming? Carlos Rittl, Greenpeace Brazil's climate campaigner says 'yes':

Greenpeace blames deforestation and climate change for the drought. "The Amazon is caught between these two destructive forces, and their combined effects
threaten to flip its ecosystems from forest to savannah," Mr Rittl said.

Even if the drought is not a result of GW it will certainly contribute to it, given that a lot of sunk carbon in the form of biomass, ecosystems and food-chains threatens to be released into the atmosphere.

To make matters worse, as the rainforest becomes increasingly dry, damaging wildfires are regularly breaking out across the region, destroying trees.

Oceans reservoir for earth's heat energy.

A recent history of GW science.

If James E. Hansen of the NASA Goddard Institute for Space Studies in New York was right in 1997 saying that the earth is absorbing about 0.5 watt per square meter of sunlight more than it is emitting back to space, then where is the heat going? Hansen speculated it was probably in the oceans. Support came in 2000 from Sydney Levitus of the National Oceanographic Data Center in Silver Spring, Md:

That knowledge inspired Levitus and his colleagues seven years ago to launch a United Nations-sponsored global search?and-rescue operation for ocean data. The team?s primary goal was to dig up every single temperature measurement they could find for the top 3,000 meters of the ocean, enough water to engulf a skyscraper seven times as tall as the World Trade Center. They knew that the deeper they looked, the more convincing any emerging temperature trends would be.
Numbers came in from all over the world. When the British Royal Navy told Levitus that it had hundreds of thousands of index cards of hand-written temperature profiles stashed away in a musty basement, the oceanographer jumped at the chance to add them to his growing database. He didn?t have to go far. Officials loaded a ship with some 100 metal file drawers full of the cards and sent them across the Atlantic. His team also uncovered unexpected measurements from World War II at the Scripps Institution of Oceanography in San Diego and rare numbers from the icy seas around Russia and Norway in an obsure book tucked away in the New York Public Library.

When they put the millions of numbers they gathered together with several million more that already existed, they discovered that the Pacific, Atlantic and Indian oceans combined warmed an average of 0.06 degree Celsius between 1955 and 1995.

What?s more, that amount of warming accounts for a majority of Hansen?s "missing heat."

* in which we have chosen the name "Terry" for our website. In case you are wondering, it is an affectionate term for the word "Terra."

This great Canadian site aims to combine art, news and geo-science. I am pleased for it to be my first link. Terry recently updated with an informative article on the developing field of Climate Modeling; what it is and why it is important.

Global warming is happening. Are we to blame or is it a natural
warming trend? Is reducing our CO2 emissions going to have any effect on
dampening this process or is it too late? How much is the earth?s temperature
going to increase in the next century and will the earth be inhabitable for
anything more than cockroaches? Climate modeling has the potential to answer
these questions. It is even more important given the influence the scientific
community can and does have on government decision making. To combat global
warming tough decisions need to be made by policy makers that may involve
sacrificing short term benefit for long term gain. Policy makers, though, are
responsible for the well being of their constituents and will only make these
tough decisions if they are given valid scientific evidence that shows the dire
consequences of not acting now. This is what climate modeling is attempting to
do.

With the economic livelihood of a good portion of the earth?s population relying on the production and consumption of fossil fuels there are a lot of questions to be answered. One thing is certain, Climate Modeling has a big future.

Gums have reason to be blue

Yesterday's article prompted this creative solution to the drought in today's SMH Letters To The Editor.

Down with those gums

Given the reported link between vegetation clearing, urban sprawl and thunderstorms ("City climate surprise - trees cut, storms grow", October 24), can I suggest we tear down those pesky gum trees and whack a few new suburbs in the Blue Mountains National Park, thereby guaranteeing that when it rains it finally does so over the catchment area?

Research: Sydney southwesterlys gather speed over tree-free west.

"We think the removal of the forest in western Sydney has allowed storms to move across a little quicker."

Macquarie University physical geography department researchers Professor Andy Pitman and his student colleague, Anna Gero, have discovered that their computer simulations of Sydney weather patterns with and without the original vegetation cover suggest that the changing landscape and specifically the western urban sprawl is also responsible for increasing the violence of some storms.

It also appeared the vegetation loss had changed the dynamics of atmospheric convection, which is a key to forming many thunderstorms that strike Sydney on summer days. Without the vegetation, sea breezes could sweep further inland, changing the location where they collided with winds blowing from the south-west. The biggest storms in the simulations formed over the central business district. Professor Pitman said they first thought the storms were being powered by turbulence caused by city buildings, "but we found it was really the cleared space south of Sydney".

The weather bureau's NSW regional director, Stephen Lellyett, said: "Upon a cursory examination, [the] work is very interesting - it appears plausible that the speed and intensity of systems tracking south-west to north-east could be modified by changes to the behaviour of the sea breeze and be a result of land-use change."

Ok, but how is this on-topic? I do observe how Sydney storms seem to be getting worse and had quietly wondered whether this was due to global warming, greenhouse gas style. If Professor Andy Pitman and his student colleague are right it is good news. The increasing serverity of storms has localised causes, at least to some extent. Re-treeing the backyards, parklands and open spaces of western Sydney could help create a storm-break that will help reduce the severity of our storms.
