Sell all your re-insurance stock

Extreme weather is here to stay:

SOMETHING strange is happening to our weather.

Sydney has endured the most sodden school holidays in living memory, including the longest unbroken spell of April drizzle for 77 years, a month after some state capitals sweated through the worst continuous period of baking heat ever recorded. And unseasonably early snow fell in the mountains at the weekend.

"The weather's been anything but normal over the last six months," said Dave Williams, a senior forecaster at the Bureau of Meteorology. "I've been in this game for 20 years, and I can't recall a longer period of sustained weather patterns, of various kinds."

The article explains that this has more to do with La Nina and a 'blocking' high pressure system, but...

"This has less to do with global warming and more to do with the natural kinks and dips you see in weather patterns each year," said Professor Matthew England, co-director of the Climate Change Research Centre at the University of NSW.

"The extremes of heat are an example of the sort of weather we can expect to see a lot more often in the next 50 years, because the evidence is indisputable that the weather is getting warmer."

Personally, I don't think the reference to global warming belongs in that story.

First to go: Iconic Polar Bear or Fabled Narwal?

Andrew Bolt repeats he doesn't want us to use polar bears as a symbol of global warming in our media any more:

Bear With Us: More Hype Deflated

The eco-hype is cooled, along with the weather:

The polar bear is in trouble in Canada because of overhunting and global warming, but it is not endangered or threatened with extinction, an independent committee advising the Canadian government said Friday.

The obligatory genuflection to global warming is there, of course, but perhaps we can now drop the absurd use of the polar bear as the emblem of global warming doom.

Andrew Bolt – Sunday, April 27, 08 (09:31 am)


He'll be pissed-off to read in Wired's story that, should his long-running persecution of the poor polar bear succeed, the narwhal is ready to drop in on its wave:

The polar bear has become an icon of global warming vulnerability, but a new study found an Arctic mammal that may be even more at risk to climate change: the narwhal.

It seems the 80,000 strong narwhal is highly specialised, reducing it's chances of adapting to a melting environment.

The narwhal, which dives about 6,000 feet to feed on Greenland halibut, is the ultimate specialist, evolved specifically to live in small cracks in parts of the Arctic where it's 99 percent heavy ice, Laidre said. As the ice melts, not only is the narwhal habitat changed, predators such as killer whales will likely intrude more often.

"Since it's so restricted to the migration routes it takes, it's restricted to what it eats, it makes it more vulnerable to the loss of those things," Laidre said in a telephone interview from Greenland, where she is studying narwhals by airplane.


Imagine the mileage that environment groups could make by elevating the fabled Narwhal 'as the emblem of global warming doom.'?

The narwhal, a whale with a long spiral tusk that inspired the myth of the unicorn, edged out the polar bear for the ranking of most potentially vulnerable in a climate change risk analysis of Arctic marine mammals.

Unravell the unicorn myth, that takes in Noah Ark and the Great Flood, a story embedded in our Abrahamic DNA, and you will have the genesis of the great green religion that Andrew so fears. He's much better off hoping the polar bears will pull through; and that's the Knuts and Bolts of it:

The Unicorn Song

A long time ago, when the Earth was green
There was more kinds of animals than you've ever seen
They'd run around free while the Earth was being born
And the loveliest of all was the unicorn

There was green alligators and long-necked geese
Some humpty backed camels and some chimpanzees
Some cats and rats and elephants, but sure as you're born
The loveliest of all was the unicorn

The Lord seen some sinning and it gave Him pain
And He says, "Stand back, I'm going to make it rain"
He says, "Hey Noah, I'll tell you what to do
Build me a floating zoo, and take some of those

Green alligators and long-necked geese
Some humpty backed camels and some chimpanzees
Some cats and rats and elephants, but sure as you're born
Don't you forget My unicorns


Don't forget the narwhal. The research study Wired's article cites was published this week in the peer-reviewed journal Ecological Applications.

Brendan Nelson holds the line on global warming

I almost forgot to tell you about my first scoop ever: Last month the leader of the Liberals, Brendan Nelson, in reply to an email I sent to him, wrote this:

As Australians, it is time for us to start living on environmental interests, rather than just capital interests.

I made the observation, then, that he 'is working up a lovely line on climate change'.

Last week Brendan told Kerry, on The 7:30 Report:

We also need, I think, to have changes in our federation, the responsibilities of government, the sharing of money, the environmental challenges so that we start to live on environmental interest instead of the capital, security and defence of our nation and its interests and values and a cohesion of our society.

Keep working that line. It's thought provoking: This Earth with all working parts in good order, our capital inheritance; it's sustainable carrying capacity, our stipend.

Not quite the t-shirt slogan needed to be Australia's next PM, but the Liberals need to move their base, quickly, to understand that the economy is a sub-system of the environment, fully. The unions did well with a parallel meme they ran during the Workchoices battle in the lead up to last year's election: We live in a society, not an economy.

Now that passes the t-shirt test.

Carbon dioxide up 2.4 ppm on last year

Here's the sobering bit: The average annual increase of carbon dioxide between 1979 and 2007 is only 1.65 parts per million (ppm). Suddenly, we are measuring a 0.5% rise in a year.

Researchers from the National Oceanographic and Atmospheric Administration Earth System Research Laboratory (ESRL) reported new data that shows a higher than usual average increase in carbon dioxide levels over the last 30 years.

The recently released report from NOAA scientists is an annual update to the agency’s greenhouse gas index, which tracks data from 60 regions around the world. Concentrations may have increased by as much as 0.5% from 2006 to 2007.

That was the consequence of the rise of China and India, Business-As-Usual in the United States and Australia, and, I believe, the successful shilling by the AGW denial industry (See post below).

The above link goes on to talk about a sharp rise in methane levels as well.

Trolling the climate trolls

Professor Barry W Brook is Director of the Research Institute for Climate Change and Sustainability at the University of Adelaide. He warns against engaging with climate change deniers on science blogs, likening them to Internet trolls:

"Don't feed the troll!" This is a common admonition in the expanding science blogosphere - at least the rational quarters.

Trolls, in the internet vernacular, are people who intentionally post false or controversial messages to gain attention or foment a conflicting style of debate. Most remain shielded within the anonymous confines of their online pseudonym. A rare but vocal few are sufficiently emboldened by self-confidence (or hubris) to speak out in public.

For the long-standing "debate" over the relative merits of evolution versus creationism, they usually style themselves as "creation scientists" or "intelligent designists". In climate science and policy, those few apparently well-educated people who continue to deny the now vast body of scientific knowledge and analysis on the causes and consequences of global warming are variously called sceptics, denialists, contrarians, delayers or delusionists. Whatever the label you attach to them, they are all cut of the same anti-intellectual cloth.

Their business is the dissemination of disinformation, doubt and unscientific nonsense. One of their most regular ploys is to leverage the widespread lack of public appreciation of how science operates. The scientific process of theoretical postulates, hypothesis testing, critical evaluation (and re-evaluation) of ever accumulating empirical evidence, model validation and peer review is inherently complex and often technical.

Quick diversion to a bugbear of mine: "Internet" is capitalised.

Meanwhile, back under the bridge at Andrew Bolt Blog, the good Professor's characterisations has Andrew raising his hand to say, 'Who me?':

UPDATE

Reader Elsie notes the Professor’s word for those who disagree on apocalyptic man-made global warming:

Trolls.


I notice that Andrew has finally accepted man-made global warming, and now seems to only be against people saying man-made global warming could be apocalyptic. A cartoon at the excellent Skeptical Science blog (as recommended by the good Prof. himself) exposes the logic supporting Andrew's numerous positions on the subject over the years. And it's a clever parody of the processed meat he throws to his gaggle murder irritation of climate trolls, on a daily basis:

I'd love to have a beer with Brendan...

...'cos Brendan's me local member; leader of the opposition; he replied to my email; .... and he is working up a lovely line on climate change:

Climate change is one of the most significant moral, political and economic challenges that will face our generation.

Ok, that's Kev07, and Blair05, and Gore06. But the next line is Brendan's. You read it here first.

As Australians, it is time for us to start living on environmental interests, rather than just capital interests.

That's a lovely, sweeping sentiment. My guess is, it is an understanding that the economy, and all that sail upon her, is but a subset of the environment.

Bit of a head-turner, given the stance of the previous Federal Liberal leader and the early rumble for leadership after Howard lost Bennelong. I had the impression Turnbull self-servingly leaked the revelation that he had earlier told the party room they had to promise to sign Kyoto to win. And this played out in the Liberal party machine as engendering disunity. So Brendo, more moderate on Kyoto, got the numbers.

That's history; Kyoto is ratified, and that bipartisan act came into effect last month. The rest of the letter from Brendan's office in response to me expressing my concerns about the need for political action, gives a clear acknowledgement of the problem, and the need to...

...focus on practical effort and initiatives that will ensure responsible environmental behaviour and will reduce greenhouse gas emissions.

So I guess their policies are nascent. The letter goes on to confirm this, say Brendan is listening to ordinary Australians, consulting widely and will consider many opinions in developing their policies, including... what for it... Global Warming Watch.

Good. I'll be suggesting how he needs to hold Labor to account.

If suddenly there were no more global warming...

...life will suddenly become a whole lot more interesting.

A great many founts of authority, from the Royal Society to the UN, most heads of government along with countless captains of industry, learned professors, commentators and journalists will be profoundly embarrassed. Let us hope it is a prolonged and chastening experience.

With catastrophe off the agenda, for most people the fog of millennial gloom will lift, at least until attention turns to the prospect of the next ice age. Among the better educated, the sceptical cast of mind that is the basis of empiricism will once again be back in fashion. The delusion that by recycling and catching public transport we can help save the planet will quickly come to be seen for the childish nonsense it was all along.

The poorest Indians and Chinese will be left in peace to work their way towards prosperity, without being badgered about the size of their carbon footprint, a concept that for most of us will soon be one with Nineveh and Tyre, clean forgotten in six months.

The scores of town planners in Australia building empires out of regulating what can and can't be built on low-lying shorelines will have to come to terms with the fact inundation no longer impends and find something more plausible to do. The same is true of the bureaucrats planning to accommodate "climate refugees".

Penny Wong's climate mega-portfolio will suddenly be as ephemeral as the ministries for the year 2000 that state governments used to entrust to junior ministers. Malcolm Turnbull will have to reinvent himself at vast speed as a climate change sceptic and the Prime Minister will have to kiss goodbye what he likes to call the great moral issue and policy challenge of our times.

It will all be vastly entertaining to watch.


Condemned to an existence of boredom and unrequited schadenfreude is one Christopher Pearson, a writer at The Australian. Detect any frustration-betraying bitterness? I guess global warming just keeps bumping into his world-view.

So what has inspired his flight of fancy, this babbling brook of consciousness, this denialist delight?

Jennifer Marohasy has. She bears news of an "impending collapse of the global warming paradigm" in an ABC Radio National discussion with the similarly excited Michael Duffy.

Duffy: "Can you tell us about NASA's Aqua satellite, because I understand some of the data we're now getting is quite important in our understanding of how climate works?"

Marohasy: "That's right. The satellite was only launched in 2002 and it enabled the collection of data, not just on temperature but also on cloud formation and water vapour. What all the climate models suggest is that, when you've got warming from additional carbon dioxide, this will result in increased water vapour, so you're going to get a positive feedback. That's what the models have been indicating. What this great data from the NASA Aqua satellite ... (is) actually showing is just the opposite, that with a little bit of warming, weather processes are compensating, so they're actually limiting the greenhouse effect and you're getting a negative rather than a positive feedback."

Duffy: "The climate is actually, in one way anyway, more robust than was assumed in the climate models?"

Marohasy: "That's right ... These findings actually aren't being disputed by the meteorological community. They're having trouble digesting the findings, they're acknowledging the findings, they're acknowledging that the data from NASA's Aqua satellite is not how the models predict, and I think they're about to recognise that the models really do need to be overhauled and that when they are overhauled they will probably show greatly reduced future warming projected as a consequence of carbon dioxide."

Duffy: "From what you're saying, it sounds like the implications of this could beconsiderable ..."

Marohasy: "That's right, very much so. The policy implications are enormous. The meteorological community at the moment is really just coming to terms with the output from this NASA Aqua satellite and (climate scientist) Roy Spencer's interpretation of them. His work is published, his work is accepted, but I think people are still in shock at this point."


Hmmm, The new NASA Aqua Satellite data, as interpreted by fossil-fuels favourite, Dr Roy Spencer. I expect we'll hear a lot of this from the shills, Bolt; Ackerman; Blair; Devine; and, Albrechton, et al., and it should be interesting to see them construct their narrative. I'll Global Warming Watch this one.

Roy Spencer was the fellow who put out a paper showing satellite data was not correlating with the climate data, and showed cooling. For years and years there was this incongruent satellite data. Then the paper was reviewed by Science Magazine in 2005, whereupon they found that Christy and Spencer had failed to take proper account of satellite drift, which produced a spurious cooling trend to their dataset.

Update
Is there a smell of freshly laid astroturfi? Yahoo7 Answers already have the question up, posed by an eric c

Update 2
Glitch, long-time reader, typically a pleasant chap (but yes, one of those skeptics) is positively rubbing his hands with glee.

LOL, this is just wonderful.... Such VERY BAD good news for the enviro-socialists...

The plot thickens. Someone thunks global warming theory has been debunked, and this is bringing on the long-promised Raptures for the AGW Skeptics. Am I witnessing Deliverance for The Doubtful Loyal?

I checked the headlines, and Reuters. Nothing.

It'll come. It's lurking out there in the gloom, ready to break the water. I'm starting to feel very Old Man Of The Sea-ish. I'm baitin' up big.

Update 3
Spencer's bio at the fossil-fuel funded Marshall Institute site tells us: He currently is the U.S. Science Team Leader for the Advanced Microwave Scanning Radiometer (AMSR-E) on NASA's Aqua satellite.

It also says: Dr. Spencer is the recipient of NASA's Medal for Exceptional Scientific Achievement and the American Meteorological Society's Special Award for his satellite-based temperature monitoring work.

In 1996, from what I can tell. The paper was debunked in 2005. That bio needs updating.

Think I'll check out Realclimate, or Deltoid. See what they have to say.

Earth Hour boomerangs back to Sydney

NSW Premier Morris Iemma, normally botox-expressioned, is suddenly sounding like a global warming alarmist by taking it to the sceptics of symbolism, and the denier of dangerous AGW.

The NSW Premier, Morris Iemma, accused critics of Earth Hour of peddling "utter rubbish" at the launch of the event at Circular Quay this morning.

"The critics and sceptics need to get on board," Mr Iemma told an audience of business supporters of Earth Hour this morning.

"It's utter rubbish to say that symbolism can't lead to change. Yes it's about symbolism but it's a very powerful one - it's about saving the planet."

...

Some of the world's largest cities would take part in the energy-reducing initiative this year and its adoption worldwide was a vital step in creating "real practical change", Mr Iemma said today.

While cynics may think Earth Hour symbolises a stick — to beat them with — it really is a boomerang.

"What started a year ago in Sydney has become a global movement as more and more cities around the globe join the battle against climate change, and it is a battle in which every one of us can make a difference," Mr Iemma said.

"[When] 2.1 million Sydneysiders just on a year ago switched off the lights, the critics and the sceptics said that it was largely a symbolic gesture.

"I don't agree with that. What the critics and the sceptics fail to understand is that symbolism can be very powerful when it comes to change.

"That's what Earth Hour is about: real practical change."

WWF-Australia, which is organising Earth Hour with the support of Fairfax Media, publisher of the Herald, said that three-quarters of the top 100 companies listed on the Australian Stock Exchange had agreed to take part.

The WWF said that all of the state's major property companies will join in, as well as 70 per cent of the state's one-, two- and three-hat restaurants, the top five banks and 85 per cent of the state's main hotels. The 50 largest local councils in NSW will also take part.

On the Facebook social networking website, 657,658 people have signed up for more than 150 separate Earth Hour events, while, on the Earth Hour website more than 80,000 people had signalled their willingness to take part, with the figures expected to spike as March 29 draws nearer.

...

Cities taking part in this year's Earth Hour include Atlanta, San Francisco and Chicago in the United States, Denmark's four largest cities, London, Dublin, Tel Aviv, Bangkok and Christchurch.

Most Australian capital cities are participating, as well as Newcastle in NSW.

3,500 tigers left — at a crossroads

Bengal tiger crossing road


Tiger, Tiger, burning bright

In the forest of the night,
What immortal hand or eye
Could frame thy fearful symmetry?


Of Panthera tigris, let not William Blake's immortal poem, or prayer if you like, be the only thing bequeathed to our descendants. Let them not read his words, and wonder what was this marvel of creation... that now is their disinheritance.

The World Wildlife Fund (WWF) estimates that there are 3,500 tigers in the world, all at the corners of Extinction Expressway and Survival Drive.

"In many ways the tiger stands at a crossroads between extinction and survival, and which path it takes is totally dependent on us," said Sujoy Banerjee, director of WWF India's species program.

The WWF's tiger coordinator based in Nepal, Bivash Pandav, said he believed there were 3,500 tigers left in the world. That compared with rough estimates of about 5,000-7,500 in 1982.

Pandav said in Sumatra, Indonesia, the number of tigers had dwindled to about 400 and the situation was now critical as forest areas have been decimated.

The demand for traditional Chinese medicines, and habitat destruction are the main culprits, with flow-on encroachment into human livestock areas also being a major cause. Out of the jungle, the tiger soon comes off second-best.

There is good news, though; tigers will turn the corner.

But additional pressure on governments to stop poaching, in particular from China, and other conservationist measures such as habitat protection could make a huge difference, he said.

"We can easily have 10,000 tigers, if everything goes as per our wish," said Pandav, adding that could be achieved in as little as 10 years.

"I firmly believe that tigers will continue to survive in certain pockets. They're not going to become extinct," he said.

Sarah Christie, a program manager for the Zoological Society of London, highlighted work being done by zoos to protect tigers, saying nearly a 10th of the money spent on tiger protection came from zoos. She said in the case of Sumatra, the total was 60 per cent.

Christie said the world's focus on climate change offered a chance to help the tiger.

"Tigers are indicators of eco-system health, they are indicators of forest health. Saving the tiger is a test. If we pass, we get to keep the planet Earth."


The irony is that you, Homo sapiens, are at the crossroads too. You need those forests as much as Panthera tigris, your children need to appreciate William Blake. Fully. So the only choices are: do you take this road, to find out more — or do you first take a sixty second detour?

Tiger, Tiger, burning bright
In the forests of the night,
What immortal hand or eye
Dare frame thy fearful symmetry?
In what distant deeps or skies
Burnt the fire of thine eyes?
On what wings dare he aspire?
What the hand dare seize the fire?
And what shoulder and what art
Could twist the sinews of thy heart?
And, when thy heart began to beat,
What dread hand and what dread feet?
What the hammer? What the chain?
In what furnace was thy brain?
What the anvil? What dread grasp
Dare its deadly terrors clasp?
When the stars threw down their spears,
And water'd heaven with their tears,
Did He smile His work to see?
Did He who made the lamb make thee?

Tiger, Tiger, burning bright
In the forests of the night,
What immortal hand or eye
Dare frame thy fearful symmetry?

- William Blake (1757-1827)

Deniers' canard blown out the water

Gordon: "No such thing as global warming."

Peter: "Why do you say so?"

Gordon: "In the '70s scientists were predicting global cooling, now they predict global warming."

Peter: "So they got that wrong?"

Gordon: "Sure did."

Peter: "So... I thought you didn't believe in global warming?"

Gordon:

Peter: "Just read Realclimate! They now have a study on what climate scientists really were saying in the '70s."

clipped from www.realclimate.org
"How can we believe climate scientists about global warming today when back in the 1970s they told us an ice age was imminent?"
If, indeed, climate scientists predicted a coming ice age, it is worthwhile to take the next step and understand why they thought this, and what relevance it might have to today's science-politics-policy discussions about climate change. If, on the other hand, scientists were not really predicting a coming ice age, then the argument needs to be retired.

Between 1965 and 1979 we found (see table 1 for details):

  • 7 articles predicting cooling
  • 44 predicting warming
  • 20 that were neutral

In other words, during the 1970s, when some would have you believe scientists were predicting a coming ice age, they were doing no such thing. The dominant view, even then, was that increasing levels of greenhouse gases were likely to dominate any changes we might see in climate on human time scales.

Exxon still financing AGW denial

Recidivists.

Well I certainly will continue to avoid their Mobil and Esso stations at all cost.

Today I noticed that BP have a 3c per litre discount if you join their 10% ethanol blend frequent fuelers club. I'll settle for a BP when an independent with ethanol blend is inconvenient.

clipped from scienceblogs.com

Remember last year, when Exxon said that they would no longer fund organizations like the International Policy Network and the George Marshall Institute that misrepresent the science of global warming?

Well, they are still funding them. Also still on the list, are CO2science and the Center for Science and Public Policy.

Man-made global warming predicted in 1896

Global warming awareness has now seeped into mainstream culture, but have you ever wondered who the first person to predict anthropogenic global warming was?

It was a lot longer back than you would imagine.

Svante August Arrhenius (February 19, 1859 – October 2, 1927) was a Swedish chemist and one of the founders of the science of physical chemistry. The Arrhenius equation and the lunar crater Arrhenius are named after him.

In 1908 Arrhenius predicted that significant global warming would take ~3000 years to develop. This is now recognised as a substantial underestimate due in part to his failure to foresee the rapid increases in fossil fuel use during the twentieth century.
The PDF link contains "On the Influence of Carbonic Acid in the Air upon the Temperature of the Ground" by Svante Arrhenius. This paper, published in 1896, is the first to quantify the impact of carbon dioxide on the Earth's greenhouse effect and to suggest that its variations have been an important influence on previous long-term changes in climate. His crude estimate that a doubling of carbon dioxide would result in a ~5 °C warming is larger but not greatly different from the 1.5-4.5 °C now estimated for such a doubling (IPCC 2001).
Image of Svante Arrhenius

Combining these calculations with existing work suggesting that the burning of fossil fuels could significantly alter the concentration of carbon dioxide in the atmosphere (Högbom 1894), Arrhenius later became the first person to predict the possibility of man-made global warming.

America's $1 trillion carbon market twelve years away

The new US president will most likely see in the emergence of a colossal carbon trading market, worth $1 trillion a year by 2020, according to a report released on Thursday.

Another report, also out this week, estimates the US could be trading $600 billion in pollution credits annually by 2015.

Either way, "it will be the largest environmental market of its kind," says Tiffany McCormick Potter, senior analyst for Point Carbon, which produced the 2015 estimate. According to Point Carbon, the European carbon trading scheme totalled $42 billion in 2007.

The 2020 estimate comes from New Energy Finance, another financial analysis firm which focuses on environmental markets. Both firms have this week published independent reports on the future of carbon trading in the US.

North Atlantic current could be slowing naturally

Global warming may not have caused sluggish Atlantic

Judging the effect of climate change on ocean currents could take longer than we thought.

The circulation of warm water in the North Atlantic is suspected to be slowing, and the worry is that global warming is to blame.

To investigate this, Carl Wunsch of the Massachusetts Institute of Technology used observations taken from buoys to build a model of Atlantic circulation. It suggested that currents could speed up or slow down naturally by a greater amount than the suspected slowdown linked to global warming, and such changes could persist over months or even years (Nature Geoscience, DOI: 10.1038/ngeo126). It will take decades of observations to account for these effects, Wunsch warns.

The clearfelled truth about Melbourne's drought

Andrew Bolt is fond of blaming Victoria's ongoing Level 3 water restrictions on the fact that they haven't built enough dams. All the greenies fault, that sort of stuff.

But The Wilderness Society have found a real culprit, and Andrew is not going to like it; the Loggers of the Water Catchment in the Central Highlands:

Logging threatens water supply and quality

Within the spectacular giant mountain ash forests of the Central Highlands lie Melbourne’s water catchments, which provide drinking water to over 3 million Victorians. Five of these catchments, which supply 40 per cent of Melbourne’s drinking water are open to clearfell logging.Logging coup in Armstrong Crk

Several independent studies, including a technical report published in December 2000, have found that clearing and regeneration of these forests has a dramatic effect on water yield.

Research has shown logged areas to suffer a 50 per cent reduced water yield (shown in graph). Young regrowth trees need more water to grow, thus releasing less water into river catchments. It takes 150 years for water yields to regain their pre-logged status.

It is breathtaking that in this time of severe drought our most precious resource is jeopardised by logging and that the Government continues to see fit to threaten the little water we have left.
