Tens of millions of people could be driven from their homes by encroaching deserts, particularly in sub-Saharan Africa and Central Asia, a report says.
The UN report suggests that new farming practices, such as encouraging forests in dryland areas, were simple measures that could remove more carbon from the atmosphere and also prevent the spread of deserts.
"Things like ecotourism or using solar energy to create other activities."

It is no secret that industry-connected appointees within the White House have worked actively to distort the findings of federal climate scientists, playing down the threat of climate change.
We see that in Bangladesh. And in Australia. New research on carbon footprints across the socio-economic spectrum here, reveals that:
At a relatively low carbon price of $25 a tonne of greenhouse pollution, poor families around Australia would be paying about $558 a year more on their bills, while the wealthiest households would pay around $1446 extra.
But once those extra costs are adjusted to take into consideration income levels, as a proportion of their total spending, poor people could pay almost seven times more than the rich.
The analysis was conducted by the Melbourne-based National Institute of Economic and Industry Research.
The last word goes to the executive director of the Brotherhood of St Laurence, Tony Nicholson, who commissioned the analysis.
"This is a great opportunity, because if we seriously address climate change we can also do a lot to address entrenched disadvantage," Mr Nicholson said.
"For instance, we're advocating a national rental incentive scheme for landlords to make private rental properties more energy efficient, because we know many disadvantaged people have high energy bills because their homes aren't properly insulated.
"Australia has a national roads strategy; why don't we have a national public transport policy? More disadvantaged people tend to have older cars that consume a lot of fuel, and many live on the outskirts of cities and in country towns. So by improving public transport, you address both problems at once."

Watch him present a risk analysis that conclusively makes the case for taking action on global warming.
I haven't seen anyone logically refute him, yet. But I'll take submissions. If you can't then do like the man says and help spread the word.

SYDNEY: The internet is not web-shaped after all. Instead, it's more more like a globe, made up of a dense core and sparsely connected outer regions, according to a mathematical analysis of its structure.
"A better understanding of the internet's structure is important in many ways," said Shavitt. "We can track the internet's evolution in time and generate predictive models to its growth [which will] help us understand how the Internet will look a few years from now so we can plan ahead."
the Internet consists of a dense, heavily connected nucleus of about 100 nodes, including Google and U.S. telecommunications giant ATT WorldNet.

Present knowledge does not permit accurate specification of the dangerous level of human-made GHGs. However, it is much lower than has commonly been assumed. If we have not already passed the dangerous level, the energy infrastructure in place ensures that we will pass it within several decades.
We conclude that a feasible strategy for planetary rescue almost surely requires a means of extracting GHGs from the air. Development of CO2 capture at power plants, with below-ground CO2 sequestration, may be a critical element. Injection of the CO2 well beneath the ocean floor assures its stability (House et al. 2006). If the power plant fuel is derived from biomass, such as cellulosic fibres grown without excessive fertilization that produces N2O or other offsetting GHG emissions, it will provide continuing drawdown of atmospheric CO2.

Not everyone is playing in tune, though.
Already, some Australian ad industry executives have taken a shot at Mr McLennan's new green credentials. "Tell Hamish Patts in Sydney has left its lights on," quipped executive chairman Euro RSCG South Pacific Group Tom Moult last week.

Estimates on when China would overtake the US on greenhouse gas emissions had varied, but Dr Fatih Birol, chief economist of the Paris-based International Energy Agency, said in April it could happen within months.
The country's economic growth had been so fast in 2006 and 2007 that the historic global shift of climate-changing emissions from west to east, which was previously predicted for 2009 or 2010, could now happen by November, Birol told the Guardian Unlimited site then.
According to the Netherlands Environmental Assessment Agency's figures, China's emissions increased by 9.0 per cent in 2006 compared to its 2005 output. In the United States emissions rose 1.4 per cent from 2005 to 2006.
All eyes are on the Senate this week as it debates a controversial Democrat-penned energy bill.
The legislation contains several provisions that make Big Oil, Big Auto, and Big Republicans squirm: it would shift nearly $15 billion in tax credits and subsidies from oil to renewable sources like wind and solar; require utilities to produce 15 percent of their power from renewables; give the feds more power to prosecute gasoline price-gouging; and mandate a fuel-efficiency standard for cars, SUVs, and small trucks of 35 miles per gallon by 2020. Ambitious! But potentially doomed, as opponents are doing their best to puncture the plans, and majority leader Sen. Harry Reid (D-Nev.) may scuttle the whole thing temporarily to take up the immigration debate instead. Meanwhile, as the House floats its own energy solutions, powerful Michigan Democrat John Dingell has backed off of plans to support coal-to-liquid fuels and weaker efficiency standards -- at least for now.

6. Scientists get paid big bucks to skew their data to indicate global warming.
It is far more lucrative to produce research denying global warming.
And with tens of thousands of scientists producing research indicating human-induced global warming, the task to compromise the ethics of so many esteemed professionals would be, to say the least, challenging.
7. Variations in solar output cause global warming.
Solar variability plays a very small role, if any, in global warming.
9. Because it snowed a great deal and got very cold in some areas, global warming isn't happening.
Global warming is about the long-term average trend.
10. It isn't possible to distinguish the effects of human activities from natural processes with regard to CO2.
We know how much CO2 a barrel of oil and we know how many barrels of oil we use.
(First 5 of 10)
3. The Earth (and its carbon cycle) is too big for humans to affect it.
During 1850-2000, through a combination of fossil fuel burning, cement manufacturing, and land-use changes, humans added a net 174 Gt of carbon. This caused the majority of an increase from 288 ppm (parts per million) to 369.5 ppm of CO2.
Without human influence, this regulatory process produces a net carbon increase of 0.0 Gt/year.
4. The sea level has not changed.
Since 1900, sea level has risen by about 35 cm (13.8 inches). This change in sea level is accelerating.

From Kevin Grandia of Desmogblog:
Thought you might be interested in this. It is a follow up to a story from about a year ago in which a retired professor, Tim Ball, filed suit against a professor of environment at the University of Lethbridge over a letter to the editor that appeared in the Calgary Herald. Since then, Dr. Ball has continued to be used as a source of climate science by popular media, including the UK Channel 4 documentary "The Great Global Warming Swindle" and CNN Glenn Beck's "Climate of Fear" special.

Ball Bails on Johnson Lawsuit14 Jun 07
The self-styled Canadian climate change expert, Dr. Tim Ball, has abandoned his libel suit against University of Lethbridge Professor of Environmental Science Dan Johnson. Ball dropped the suit without conditions, but also without acknowledging that Johnson's original comments were accurate and were reported in good faith.
"This is great news," Dr. Johnson said today, "but it still leaves a cloud over my name that I would like removed. Even though I can now demand that Ball pay what the court calls 'taxed costs,' that won't begin to cover the actual legal bills, to make up for lost time or to repair the damage that Ball has done to my reputation."
Ball, a spokesperson for two industry front groups fighting against climate change regulation, sued Johnson and the Calgary Herald over a letter the paper ran on April 23, 2006. In an earlier Opinion Page article in which Ball attacked the qualifications of renowned climate change author Tim Flannery, the Herald described Ball as "the first climatology PhD in Canada and … a professor of climatology at the University of Winnipeg for 28 years."
Johnson wrote a Letter to the Editor challenging those details. He noted that when Ball received his PhD (in Geography) in 1983, "Canada already had PhDs in climatology and it is important to recognize them and their research." Johnson also pointed out that Ball had been a professor for a much shorter time (Ball later admitted eight years), during which Ball did "not show any evidence of research regarding climate and atmosphere."
Ball filed suit, asking for damages of $325,000 plus costs.
But Calgary Herald satisfied itself as to the accuracy of Dan Johnson's letter, and rose in defence. In a Statement of Defence filed with the Alberta Court of Queen's Bench, the Herald dismissed Ball's "credibility and credentials as an expert on the issue of global warming," saying: "The Plantiff (Dr. Ball) is viewed as a paid promoter of the agenda of the oil and gas industry rather than as a practicing scientist."
In the face of this rebuff, and of the earlier Statement of Defence filed by Dan Johnson, Ball discontinued his lawsuit.
Since his retirement from the University of Winnipeg in 1995, Tim Ball has worked as an industry-supported climate-change campaigner, sowing doubt about the science of global warming. He first associated himself with a Calgary-based group called the Friends of Science, which the Globe and Mail reported in August of 2006 was funded primarily by the oil and gas industry. Ball then moved to the chairmanship of a new group called the Natural Resources Stewardship Project, which the Toronto Star reported in January 2007, is a creation of the Toronto-based energy-industry lobby firm the High Park Group.
"I never intended any specific damage to Tim Ball's reputation," Dan Johnson said today. "But climate change is a critical global issue and I thought it was important to set the record straight. If people want to argue the science, I'm all for that, but Tim Ball was claiming expertise and specific credentials that he does not have. That needed to be corrected."
Johnson said he is now considering whether to accept basic costs or to seek special costs, adding, "I also deserve an apology. I think the nation deserves an apology."
Johnson said he would like to thank and acknowledge James Hoggan and the team of DeSmogBlog.com for offering considerable assistance in putting together his defence.

Sixteen gallons of oil. That's how much the average American soldier in Iraq and Afghanistan consumes on a daily basis -- either directly, through the use of Humvees, tanks, trucks, and helicopters, or indirectly, by calling in air strikes.
...an April 2007 report by a defense contractor, LMI Government Consulting, suggests that the Pentagon might consume as much as 340,000 barrels (14 million gallons) every day. This is greater than the total national consumption of Sweden or Switzerland.
The resulting study, "Transforming the Way the DoD Looks at Energy," was a bombshell. Determining that the Pentagon's favored strategy of global military engagement is incompatible with a world of declining oil output, LMI concluded that "current planning presents a situation in which the aggregate operational capability of the force may be unsustainable in the long term."
LMI arrived at this conclusion from a careful analysis of current U.S. military doctrine.
Habitats are expected to shift further north as the planet warms, and plants' inability to move quickly enough has been a cause for concern.
But researchers, writing in the journal Science, suggest seeds can be carried vast distances by the wind and sea ice.
The biggest challenge, they added, was likely to be their ability to establish themselves in the new habitat.
Researchers from Norway and France analysed more than 4,000 samples of nine flowering plant species found on the remote Svalbard islands inside the Arctic Circle.
By analysing the genetic fingerprints of the plants, the team reconstructed past plant colonization and decline in the area.
