Sharp decline in public's belief in climate threat, British poll reveals
Juliette Jowit, Guardian
Public conviction about the threat of climate change has declined sharply after months of questions over the science and growing disillusionment with government action, a leading British poll has found.

The proportion of adults who believe climate change is "definitely" a reality dropped by 30% over the last year, from 44% to 31%, in the latest survey by Ipsos Mori.

Overall around nine out of 10 people questioned still appear to accept some degree of global warming. But the steep drop in those without doubts will raise fears that it will be harder to persuade the public to support actions to curb the problem, particularly higher prices for energy and other goods...

Methane levels may see 'runaway' rise, scientists warn
Michael McCarthy, The Independent
Atmospheric levels of methane, the greenhouse gas which is much more powerful than carbon dioxide, have risen significantly for the last three years running, scientists will disclose today – leading to fears that a major global-warming "feedback" is beginning to kick in.

For some time there has been concern that the vast amounts of methane, or "natural gas", locked up in the frozen tundra of the Arctic could be released as the permafrost is melted by global warming. This would give a huge further impetus to climate change, an effect sometimes referred to as "the methane time bomb".

This is because methane (CH4) is even more effective at retaining the Sun's heat in the atmosphere than CO2, the main focus of international climate concern for the last two decades. Over a relatively short period, such as 20 years, CH4 has a global warming potential more than 60 times as powerful as CO2, although it decays more quickly.

Now comes the first news that levels of methane in the atmosphere, which began rising in 2007 when an unprecedented heatwave in the Arctic caused a record shrinking of the sea ice, have continued to rise significantly through 2008 and 2009.

The new figures will be revealed this morning at a major two-day conference on greenhouse gases in the atmosphere, taking place at the Royal Society in London. They will be disclosed in a presentation by Professor Euan Nisbet, of Royal Holloway College of the University of London, and Dr Ed Dlugokencky of the Earth System Research Laboratory in Boulder, Colorado, which is run by the US National Oceanic and Atmospheric Administration (NOAA)...

World's coral reefs could disintegrate by 2100
Ian Sample, The Guardian
The world's coral reefs will begin to disintegrate before the end of the century as rising carbon dioxide levels in the atmosphere make the oceans more acidic, scientists warn.

The research points to a looming transition in the health of coral ecosystems during which the ability of reefs to grow is overwhelmed by the rate at which they are dissolving.

More than 9,000 coral reefs around the world are predicted to disintegrate when atmospheric carbon dioxide levels reach 560 parts per million.

The amount of carbon dioxide in the atmosphere today stands at around 388ppm, but is expected to reach 560ppm by the end of this century.

Coral reefs are at the heart of some of the most biodiverse marine ecosystems in the world. They are home to more than 4,000 species of fish and provide spawning, refuge and feeding areas for marine life such as crabs, starfish and sea turtles.

"These ecosystems which harbour the highest diversity of marine life in the oceans may be severely reduced within less than 100 years," said Dr Jacob Silverman of the Carnegie Institution in Stanford University, California.

...From these data the researchers created a global map of more than 9,000 coral reefs, which showed that all are threatened with disintegration when carbon dioxide levels in the atmosphere reach 560ppm. Silverman was speaking at the American Association for the Advancement of Science meeting in San Diego.

In a separate study, Simon Donner, an environmental scientist at the University of British Columbia in Canada, warned that carbon dioxide in the atmosphere is already at a high enough level to cause devastating coral bleaching...

We're Headed for the Greatest Resource-Sharing Problem of All Time
Tom Athanasiou, Earth Island Journal via Alternet
First, a confession: This is not another enumeration of confident judgments. I will not tell you that Copenhagen was an unmitigated failure. Or that this failure was Obama’s fault. Or that, as is the new fashion, China was the ugliest of them all. I will not say that the South’s negotiators made impossible demands. Or argue that the United Nations’ process is unwieldy and obsolete. I will not claim that only domestic US action really matters. Nor will I talk of a “North-South impasse” or a “US-China polluters pact,” two popular formulations that misleadingly imply an equal division of blame.

I will say this: Almost two decades after I started working on climate change, I was happily astounded to witness the crystallization, on the streets of Copenhagen, of a grassroots movement that was both energetic and sophisticated, and to see global civil society groups working in solidarity with the leaders of the world’s poorest and most vulnerable nations to press a collective agenda. And I can tell you something else: Our chances of preventing climate catastrophe rests in large part on the ability of this new alliance to communicate to the world’s richest and most powerful peoples that the emissions emergency is, above all things, a crisis of justice.

As everyone knows, the Copenhagen talks failed to catapult us into the ambitious global mobilization we need to reduce greenhouse gas emissions. But this was never going to happen anyway. What did happen, as the veteran Bangladeshi policy activist Saleemul Huq put it, was “a shaking of the traditional pieces of the global geo-political puzzle and their landing in a new and unfamiliar configuration.” In this sense, the question of success and failure is moot. The real question is whether the new configuration offers us fresh ways forward...
