'Evil twin' threatens world oceans, scientists warn
"Ocean conditions are already more extreme than those experienced by marine organisms and ecosystems for millions of years," the researchers say in the latest issue of the journal Trends in Ecology and Evolution (TREE).
"This emphasises the urgent need to adopt policies that drastically reduce CO2 emissions."
Ocean acidification, which the researchers call the 'evil twin of global warming', is caused when the CO2 emitted by human activity, mainly burning fossil fuels, dissolves into the oceans. It is happening independently of, but in combination with, global warming.... "Evidence gathered by scientists around the world over the last few years suggests that ocean acidification could represent an equal - or perhaps even greater threat - to the biology of our planet than global warming." ...

That's a greater theoretical threat, right?

South Africa is becoming a high-carbon zone to attract foreign investment
With its sky-high poverty levels and average life expectancy of just 51 years, South Africa is not a country we generally associate with extravagant binge-flying lifestyles, turbo-consumerism, and shopping trips to New York. How bizarre then that per capita carbon emissions in South Africa are now higher than in many European countries. While most South Africans are unlikely to ever own a plasma screen TV or Hummer, their carbon footprints still appear to be only slightly less than your average Japanese, and their national carbon emissions are now greater than those of France.
The situation becomes more comprehensible when you look at South Africa's industrial base, with 60 percent of South Africa's electricity being guzzled by heavy industry, and most of that comes from dirty coal. Now this key global climate player wants another coal station that would pollute as much as the two dirtiest plants in Britain put together, and cause a further surge in its national emissions - and they want you to pay for it. Far from benefiting ordinary South Africans, they will also be forced into subsidising this artificially low-cost electricity, for the benefit of multinational mining companies. It's no wonder that African civil society movements are leading the opposition to this development.... That's why it's so odd that western governments, including our own, now seem determined to egg them on by making a $3.7bn (£2.4bn) World Bank loan to the South African state-owned power company Eskom to help build one of the most polluting power stations in the world. With one hand the government complains about major emerging economies not doing enough to embrace low-carbon development, while at the same time, it directs money that's meant for aid, into dirty coal developments that power the international mining industry. ...

Maybe this is the World Bank's way of saying "let's get this over with."

Evidence suggests changing environment can bring down a civilization
Decades of drought, interspersed with intense monsoon rains, may have helped bring about the fall of Cambodia's ancient Khmer civilization at Angkor nearly 600 years ago, according to an analysis of tree rings, archeological remains and other evidence. The study, published this week in the journal Proceedings of the National Academy of Sciences, may also shed light on what drives - and disrupts - the rainy season across much of Asia, which waters crops for nearly half the world's population.... Similar studies suggest that abrupt environmental changes may have pushed other ancient civilizations over the edge, including the Anasazi people of the southwestern United States; the Maya people of Central America, and the Akkadian people of Mesopotamia. There is some evidence that other once-powerful kingdoms in what is now Vietnam and Myanmar may have fallen during the late 1700s, following extreme dry and wet periods.
"Both human society and the Earth's climate system are complex systems capable of unexpected behavior. Through the long-term perspective offered by climate and archaeological records, we can start to identify and understand the myriad ways they may interact," said study coauthor Kevin Anchukaitis, a tree ring scientist at Lamont. "The evidence from monsoon Asia should remind us that complex civilizations are still quite vulnerable to climate variability and change." ...

Thank goodness we are the first invulnerable civilization.

from New York times:
Among Weathercasters, Doubt on Warming
Climatologists, who study weather patterns over time, almost universally endorse the view that the earth is warming and that humans have contributed to climate change. There is less of a consensus among meteorologists, who predict short-term weather patterns.... "There is a great deal of consternation among a lot of us over the readjustment of data that is going on and some of the portrayals that we are seeing," Mr. Bastardi said in a video segment posted recently on AccuWeather's Web site.
Such skepticism appears to be widespread among TV forecasters, about half of whom have a degree in meteorology. A study released on Monday by researchers at George Mason University and the University of Texas at Austin found that only about half of the 571 television weathercasters surveyed believed that global warming was occurring and fewer than a third believed that climate change was "caused mostly by human activities."... The split between climate scientists and meteorologists is gaining attention in political and academic circles because polls show that public skepticism about global warming is increasing, and weather forecasters -- especially those on television -- dominate communications channels to the public. ...

It's simple. I just believe whoever's better-looking!

Proposed shipping industry climate regulations left all at sea
Negotiations over how to fit shipping into any post-Kyoto climate change treaty ended in another stalemate on Friday, after the United Nations shipping agency failed to reach agreement on a proposal aimed at curbing carbon emissions from new ships.... The proposals included plans for an energy efficiency index designed to help operators assess the environmental credentials of new vessels, as well as the development of clearer fuel efficient best practices for existing and new ships. But delegates failed to reach a consensus and said more work was needed on the plans. "Development of the technical issues did not progress to a degree that the measures could be considered complete"... ...

James Lovelock: Humans are too stupid to prevent climate change
Humans are too stupid to prevent climate change from radically impacting on our lives over the coming decades. This is the stark conclusion of James Lovelock, the globally respected environmental thinker and independent scientist who developed the Gaia theory.... "I don't think we're yet evolved to the point where we're clever enough to handle a complex a situation as climate change," said Lovelock in his first in-depth interview since the theft of the UEA emails last November. "The inertia of humans is so huge that you can't really do anything meaningful."
One of the main obstructions to meaningful action is "modern democracy", he added. "Even the best democracies agree that when a major war approaches, democracy must be put on hold for the time being. I have a feeling that climate change may be an issue as severe as a war. It may be necessary to put democracy on hold for a while." ...
