World's leading scientists in desperate plea to politicians to act on climate change
In what was described as a watershed moment, more than 2,500 leading environmental experts agreed a statement that called on governments to act before the planet becomes an unrecognisable -- and, in places, impossible -- place to live. At an emergency climate summit in Copenhagen, scientists agreed that "worst case" scenarios were already becoming reality and that, unless drastic action was taken soon, "dangerous climate change" was imminent.... In a strongly worded message that, unusually for academics, appealed directly to politicians, they said there was "no excuse for inaction" and that "weak and "ineffective" governments must stand up to big business and "vested interests".... Steps should be "vigorously and widely implemented", they said, to reduce greenhouse gases. Failure to do so would result in "significant risk" of "irreversible climatic shifts", the statement added... Prof Kevin Anderson, the research director at the Tyndall Centre for Climate Change Research in Manchester, said: "Scientists have lost patience with carefully constructed messages being lost in the political noise. We are now prepared to stand up and say enough is enough." ...


You mean... more study isn't needed?

from Science Daily (US):
Climate Change Reduces Nutritional Value Of Algae
Dutch researchers wanted to know whether an increased CO2 concentration exerted an influence on underwater life. They therefore examined freshwater micro-algae: small, floating and mostly unicellular algae. The experiments were performed in large tanks called limnotrons. These were aerated with ordinary air or with air containing an elevated concentration of CO2. The researchers then examined the ratio between the important elements carbon, nitrogen and phosphorous.... The micro-algae grew faster at a higher CO2 concentration, exactly as the researchers had expected. Yet this growth was also associated with a change in the composition of the algae. The algae cultured at a higher CO2 concentration contained relatively more carbon and relatively less phosphorous. This meant a reduction in the nutritional value, which could have detrimental effects upon the small animals that eat the algae such as water fleas. These in turn form food for fish, for example. As they are the first link in the underwater food chain, the algae ultimately influence the entire ecosystem. ...


C'mon, with all the algal blooms happening, there'll be lots more for the water fleas to eat!

Proposal: Make Every Earthling Pay Their Personal Carbon Debt (Sort of)
Today, an international team of scientists proposed a new way of deciding who needs to cut what: Set up a scheme in which every person on Earth has the same climate pollution limit— "a global personal emissions cap." The system would work by first setting a global limit for each year—ideally to be determined by the science, said Heleen de Coninck of the Energy Research Centre of the Netherlands. If, for example, negotiators set the global emissions limit for 2030 at 30 billion tons of carbon dioxide emitted, each nation would determine what its citizens' individual responsibilities to cut emissions were to achieve that cut and then add them up. The approach, said de Coninick, could really shake up negotiations. Individual Americans in 2005, for example, were responsible for roughly 19 tons of CO2 each per year on average. China's average was about 4 tons. Under the scientists' proposal, the world limit in 2030 would be 11 tons per person. So negotiators would calculate the per capita emissions cuts that each country would be responsible for. It would be up to individual goverments to decide how to divvy up the cuts, but the end result would be that the average U.S. emitter would have to cut more than the average Chinese. ...

from Christian Science Monitor:
Canada’s carbon sink has sprung a leak
Billions of tiny mountain pine beetles are treating Canada’s boreal forest like a 3,000-mile-long salad bar, transforming a key absorber of carbon dioxide greenhouse gas into a CO2 emitter instead. In just a decade, exploding beetle populations and a rise in wildfires have flipped Canada’s boreal forest from its longstanding role as a natural carbon vacuum – sucking up 55 million or more tons of CO2 annually – to that of a giant tailpipe emitting up to 245 million tons of CO2 each year, according to the Canadian Forest Service. That sharp about-face is raising questions about the future of northern forests worldwide that are being hit hard by global warming – including Russia’s massive boreal expanse, where wildfires have risen dramatically. ...

from London Times:
Climate scientists warn that world is heading for war of the resources
There is a 50-50 chance of temperature rises reaching dangerous levels over the next century, climate scientists have warned. Even with heavy cuts in greenhouse gas emissions of 3 per cent a year from 2015, the chance of preventing the temperature rise from exceeding 2C by 2050 is no more than half. And every decade's delay in reducing emissions will cause temperatures to go up by half a degree. European leaders have made a commitment to limiting rises to 2C because anything above that is expected to damage people's lives and the environment. A 2C increase would in itself cause more heat waves and droughts, many of which could be worse than the 2003 heat wave, which killed thousands of people across Europe. ...


"50-50 chance"? Must be a prediction from Pollyanna Institute.

China's Greenhouse Gas Emissions Threaten to Double
...China is already the world's fourth-largest economy. It will continue to expand at a steady pace even though the financial crisis has somewhat tempered its previously booming growth. There will be more city and road construction, infrastructure and transportation projects, as well as expanding industrial production. China opened 47 new airports between 1990 and 2002, and its highway network grew by 800,000 kilometers (500,000 miles) from 1981 to 2002. By 2030, China's population is expected to have grown from 1.3 to 1.5 billion people. More and more urban households will adopt a Western lifestyle by then, complete with air-conditioning, refrigerators, television sets, computers and other appliances. ...


It's starting to feel like the earth's tectonic plates are made of china.
