As emissions increase, carbon 'sinks' get clogged
In the race to reduce greenhouse gases in the atmosphere, scientists have been looking to forests and oceans to absorb the pollution people generate. Relying on nature to compensate for human excesses sounds like a win-win situation -- except that these resources are under stress from the very emissions we are asking them to absorb, making them less able partners in the pact...a global society of conservation biologists has launched a lobbying campaign, asking key decision-makers -- from the Danish officials chairing next week's climate talks in Copenhagen to U.S. lawmakers -- to push for steeper emission cuts to ensure that humans do not exhaust forests' capacity to store carbon in the decades to come. ...


Man up!, natural resources!

Antarctica was climate refuge during Permian extinction
The cool climate of Antarctica was a refuge for animals fleeing climate change during the biggest mass extinction in Earth's history, suggests a new fossil study. The discovery may have implications for how modern animals will adapt to global warming. Around 250 million years ago, at the end of the Permian period, about 90 per cent of land species were wiped out as global temperatures soared. A cat-sized distant relative of mammals, Kombuisia antarctica, seems to have survived the extinction by fleeing south to Antarctica.... It is still not certain what caused the end-Permian global warming and subsequent mass extinctions, but a leading theory is that massive volcanic eruptions in Siberia poured carbon dioxide into the atmosphere, driving temperatures up dramatically worldwide and forcing many species into extinction. ...


Antarctica: the last refuge.

CO2 levels rising in troposphere over rural areas
Spanish researchers have measured CO2 levels for the past three years in the troposphere (lower atmosphere) over a sparsely inhabited rural area near Valladolid. The results, which are the first of their kind in the Iberian Peninsula, show that the levels rose "significantly" between 2002 and 2005. Over recent years, physicists and meteorologists have been trying to find out about carbon dioxide (CO2) levels, and how these have evolved in the troposphere over various urban and rural areas around the planet. Now a scientific team from the University of Valladolid (UVA) has published the first -- and to date the only -- measurements for the Iberian Peninsula.... The study... shows that CO2 levels increased by 8 ppm (parts per million) between 2002 and 2005. A broader study has led the researchers to predict "an annual increase of 3 ppm" in the study area. ...


Rural tropospheres -- they're just a theory, right?

Dying to be green? Try 'bio-cremation'
...A standard cremation spews into the air about 400 kilograms (880 pounds) of carbon dioxide -- a greenhouse gas blamed for global warming -- along with other pollutants like dioxins and mercury vapor if the deceased had silver tooth fillings. On top of that each cremation guzzles as much energy, in the form of natural gas and electricity, as a 500-mile (800 kilometer) car trip. Enter alkaline hydrolysis, a chemical body-disposal process its proponents call "bio-cremation" and say uses one-tenth the natural gas of fire-based cremation and one-third the electricity. C02 emissions are cut by almost 90 percent and no mercury escapes as fillings and other metal objects, such as hip or knee replacements, can be recovered intact and recycled. ...


The greenest thing is not to be conceived in the first place.

Copenhagen climate summit: 50/50 chance of stopping catastrophe, Lord Stern says
An ambitious deal to cut greenhouse gas emissions needs to be agreed at the Copenhagen climate summit to give a 50/50 chance of keeping temperatures from rising more than 2C, Lord Stern has said. But failure to secure a new agreement could put the world at risk of temperature rises of more than 5C - a change in climate which he said "could only be described as catastrophic." ...

Increasing Ocean Acidification Is Tipping Fragile Balances within Marine Ecosystems
Falling pH levels are particularly harmful for calcifying organisms such as coral and shellfish, which have a harder time building and maintaining their calcium-based exteriors as the ocean grows more acidic.... In fact, some ocean researchers fear that acidification will obliterate Earth's coral reefs in as few as 50 years. That's why they have begun to design cryogenically cooled coral preservation "arks" where polyps can be stored to stave off total extinction.... Corals aren't the only species likely to be affected by the ongoing acidification of the world's oceans. According to marine ecologist Joanie Kleypas, ocean acidification could affect ocean life forms ranging from tiny algae to giant whales in unpredictable ways.... Damage to populations of the tiniest plants and creatures, whether through rising water temperature, greater acidity or loss of habitat, can spread through an entire food chain, throwing it out of balance. Consider, for example, the tiny pterapod, a marine snail whose shell is affected by changing pH. The pterapod is an important food source for young salmon, mackerel, herring and cod, which are important food sources for larger animals and economic sources for humans. ...

World carbon emissions overshoot "budget": PwC
OSLO (Reuters) - The world has emitted extra greenhouse gases this century equivalent to the annual totals of China and the United States above a maximum for avoiding the worst of climate change, a study estimated on Tuesday. Global accounting firm PriceWaterhouseCoopers said in the report that almost all major nations, including European Union countries that pride themselves on climate policies, were lagging since 2000 in a push for low-carbon growth.... "If you stay on this path the entire carbon budget will be used by about 2034, about 16 years early," John Hawksworth, head of macroeconomics at PwC, told Reuters of the report, based on a new PwC Low Carbon Economy Index. ...

Intrigue and Plot Twists in Global Climate Talks
In the otherwise ponderous and unhurried context of global climate negotiations, the past two weeks have seen a variety of gripping twists. It started this month in Singapore, where Barack Obama, the U.S. president, and other leaders used the sidelines of an economic forum to deflate expectations for a treaty at the December climate summit meeting in Copenhagen... Those rooting for a climate pact at Copenhagen were left to mull over the meeting's shrinking significance until -- twist! -- computer hackers turned the global climate conversation on its head with a trove of spicy e-mail messages. ...


With the amount of sex available in Copenhagen, the spiciness has only begun.
