Nitrogen cycle now in climate models, refines global predictions
For the first time, climate scientists from across the country have successfully incorporated the nitrogen cycle into global simulations for climate change, questioning previous assumptions regarding carbon feedback and potentially helping to refine model forecasts about global warming.... In this case, scientists found that the rate of climate change over the next century could be higher than previously anticipated when the requirement of plant nutrients are included in the climate model.... But by taking the natural demand for nutrients into account, the authors have shown that the stimulation of plant growth over the coming century may be two to three times smaller than previously predicted. Since less growth implies less CO2 absorbed by vegetation, the CO2 concentrations in the atmosphere are expected to increase. ...

Last time carbon dioxide levels were this high: 15 million years ago, scientists report
"The last time carbon dioxide levels were apparently as high as they are today -- and were sustained at those levels -- global temperatures were 5 to 10 degrees Fahrenheit higher than they are today, the sea level was approximately 75 to 120 feet higher than today, there was no permanent sea ice cap in the Arctic and very little ice on Antarctica and Greenland," said the paper's lead author, Aradhna Tripati, a UCLA assistant professor in the department of Earth and space sciences and the department of atmospheric and oceanic sciences.... Levels of carbon dioxide have varied only between 180 and 300 parts per million over the last 800,000 years -- until recent decades, said Tripati, who is also a member of UCLA's Institute of Geophysics and Planetary Physics. It has been known that modern-day levels of carbon dioxide are unprecedented over the last 800,000 years, but the finding that modern levels have not been reached in the last 15 million years is new. ...

China leads accusation that rich nations are trying to sabotage climate treaty
The US and other developed countries are attempting to "fundamentally sabotage" the Kyoto protocol and all-important international negotiations over its next phase, according to coordinated statements by China and 130 developing countries at UN climate talks in Bangkok today. As 180 countries started a second week of talks, the developing countries showed their deep frustration at the slow pace of the negotiations on a global climate deal, which are planned to be concluded in two months' time in Copenhagen.
"The reason why we are not making progress is the lack of political will by Annex 1 [industrialised] countries. There is a concerted effort to fundamentally sabotage the Kyoto protocol," said ambassador Yu Qingtai China's special representative on climate talks. "We now hear statements that would lead to the termination of the protocol. They are introducing new rules, new formats. That's not the way to conduct negotiations," said Yu. ...

Chamber: Global Warming is Good for You
After losing several high-profile members over its climate policy, the US Chamber of Commerce spent much of this week attempting to convince the public that it does believe global warming is a serious concern that Congress should act upon. But in comments recently submitted by the group to the Environmental Protection Agency, the group advanced a very different view. In its submission, the Chamber questioned the science behind the phenomenon of climate change, suggested that humans are now less vulnerable to rising temperatures because of the growing use of air conditioners -- and theorized that even if the planet is getting warmer, that might be a good thing. ...

Copenhagen on a knife edge as US plays down climate bill expectations
The ongoing Copenhagen negotiations received a dual blow on Friday, as the White House admitted for the first time that it was unlikely to pass a US climate bill this year and the UN's top climate change official expressed disappointment at the pace of the current talks in Bangkok.
Speaking as the Bangkok conference enters its second week, Yvo de Boer, head of the UN Climate Change Secretariat, told reporters that efforts to trim the 180-page draft negotiating text were still moving too slowly. "Progress toward high industrialised-world emissions cuts remains disappointing during these talks. We're not seeing real advances there," he said. "Movement on the ways and means and institutions to raise, manage and deploy financing support for the developing world's climate action also remains slow." ...

Unstoppable sea level rise
A rise of at least two metres in the world's sea levels is now almost unstoppable, experts told a climate conference at Oxford University on Tuesday.
"The crux of the sea level issue is that it starts very slowly but once it gets going it is practically unstoppable," said Stefan Rahmstorf, a scientist at Germany's Potsdam Institute and a widely recognised sea level expert.
"There is no way I can see to stop this rise, even if we have gone to zero emissions..."
Rahmstorf estimated that if the world limited warming to 1.5 degrees then it would still see two metres sea level rise over centuries, which would see some island nations disappear.
His best guess was a one metre rise this century, assuming three degrees warming, and up to five metres over the next 300 years. ...

Big business pushes for climate action
Two coalitions of top U.S. corporations are using Washington visits and more than $1 million in advertising to prod the Senate and White House to accelerate work on an energy and climate bill.
Executives from the groups tell POLITICO that they will argue they need certainty to plan for the future. And although some companies disagree, these executives contend that many businesses, and the overall economy, would eventually benefit from the new law.... in a new open letter to President Barack Obama and the U.S. Senate, two dozen major brands -- ranging from eBay to HP to Gap to PG&E -- declare: "We are business leaders from companies of all sizes and many sectors calling for your leadership. We call on you to enact comprehensive legislation. ... Now it's time for the United States Senate to act."
