Global warming could be accelerated by permafrost thawing (Cached) 8.4.2014 DNA: Money
Researchers have found new evidence that permafrost thawing is releasing large quantities of greenhouse gases into the atmosphere via plants, which could accelerate warming trends. Suzanne Hodgkins, the lead author on the paper and a doctoral student in chemical oceanography at Florida State, said they've known for a while now that permafrost is thawing, asserting what they've found is that the associated changes in plant community composition in the polar regions could lead to way more carbon being released into the atmosphere as methane. Permafrost is soil that is frozen year round and is typically located in polar regions. As the world has gotten slightly warmer, that permafrost is thawing and decomposing, which is producing increased amounts of methane. Relative to carbon dioxide, methane has a disproportionately large global warming potential. Methane is 33 times more effective at warming the Earth on a mass basis and a century time scale relative to carbon dioxide. As the plants break down, they ...

IPCC report proposes sucking carbon out of the air as climate fix 7.4.2014 Guardian: Environment
Technique of burning biomass then pumping released carbon underground included in leaked draft from UN climate panel

An upcoming UN report suggests that unproven technologies to suck carbon out of the air might be a fix for climate change, according to a leaked draft obtained by the Guardian.

Scientists and government officials gather in Berlin this week ahead of Sunday's publication of the Intergovernmental Panel on Climate Change's third part of its series of blockbuster climate change reports, which deals with policies addressing the emissions that drive global warming.

Oslo, April 6 (Reuters): World powers are running out of time to slash their use of high-polluting fossil fuels and stay below agreed limits on global warming, a draft UN study to be approved this week shows.

Fracking firm to drill on former explosives site 4.4.2014 Guardian: Environment
Dart Energy says the site is safe, but opponents warn of unexploded bombs and incomplete safety tests A leading fracking firm is to start drilling on the former site of a huge explosive factory, in a decision described as "beyond comprehension" by the local MP. Dart Energy, which is expected to begin drilling this weekend, says the site is "absolutely" safe. But opponents say there is a risk of unexploded bombs and that safety tests have not yet been completed. The revelations add to concerns about the regulation of "unconventional" gas exploration in the UK, which has seen deformed wells go unreported , planning rules breached and trespassing ...

warm regard (Cached) 1.4.2014 Telegraph: Opinion
More than 300 scientists from 115 countries, forming a Nobel-winning intergovernmental panel chaired by an Indian, have made some dire, but not hopeless, pronouncements on climate change from Japan. This is the second of three reports from the United Nations panel on climate change, specifically on the effect of global warming caused by greenhouse gas emissions on people and the planet. The first had made an erroneous prediction on the melting of Himalayan glaciers that had tarnished the panel's credibility. So it has made absolutely sure this time to deliver a foolproof report on state-of-the-art studies and opinions on exactly how bad, and how remediable, the effect of climate change will be on human, animal and natural lives. The threat, it seems, had been underestimated, both of the extent of warming and of predicted rise in sea-levels. The primary threat is to food security, with declining crop yields (especially wheat and corn) leading to inflation, migration and conflict. Human security would also ...

James Lovelock: environmentalism has become a religion 31.3.2014 Guardian: Environment

Scientist behind the Gaia hypothesis says environment movement does not pay enough attention to facts and he was too certain in the past about rising temperatures

Environmentalism has "become a religion" and does not pay enough attention to facts, according to James Lovelock.

The 94 year-old scientist, famous for his Gaia hypothesis that Earth is a self-regulating, single organism, also said that he had been too certain about the rate of global warming in his past book, that "its just as silly to be a [climate] denier as it is to be a believer and that fracking and nuclear power should power the UK, not renewable sources such as windfarms.

UK greenhouse gas emissions fall by 2% 27.3.2014 Guardian: Environment

Less coal and gas usage to generate electricity sees a marginal drop in carbon emissions in 2013, figures show

UK greenhouse gas emissions fell by nearly 2% last year, as less coal and gas was burned to generate electricity.

But official figures published on Thursday show that because of increases in 2010 and 2012, the UK's carbon footprint is still roughly the same as it was in 2009 despite government promises to cut emissions.

10,000 people to research link between humans and Australia's record heat 25.3.2014 Guardian: Environment

Tens of thousands of home computers will help create weather scenarios to find out why 2013 was a record-breaker

An international team of climate scientists is looking to recruit 10,000 members of the public to help find out the exact role greenhouse gases played in Australia’s record temperatures last year.

The Weather@home ANZ project will use people’s home computers to run a series of simulations based on the weather experienced in 2013, which has been confirmed as Australia’s hottest year on record.

Global warming to hit Asia hardest, warns new report on climate change 23.3.2014 Guardian: Environment
Flooding, famine and rising sea levels will put hundreds of millions at risk in one of the world's most vulnerable regions

People in coastal regions of Asia, particularly those living in cities, could face some of the worst effects of global warming, climate experts will warn this week. Hundreds of millions of people are likely to lose their homes as flooding, famine and rising sea levels sweep the region, one of the most vulnerable on Earth to the impact of global warming, the UN states.

The report – Climate Change 2014: Impacts, Adaptation and Vulnerability – makes it clear that for the first half of this century countries such as the UK will avoid the worst impacts of climate change, triggered by rising carbon dioxide levels in the atmosphere. By contrast, people living in developing countries in low latitudes, particularly those along the coast of Asia, will suffer the most, especially those living in crowded cities.

Did Nasa fund 'civilisation collapse' study, or not? | Nafeez Ahmed 22.3.2014 Guardian: Science
Journalistic standards won't be upheld by attempting to discredit science we don't like Environmental journalism's watchdog strikes Blogger Keith Kloor, who writes for Discover magazine, claims that my article on a Nasa-funded study modelling civilisational collapse scenarios is so inaccurate that it constitutes "a sad commentary on journalism today." The actual study, he claims, had no connection to Nasa whatsoever. Rather, I "disingenously hyped" the paper "as being 'Nasa-sponsored'", when in fact, it simply wasn't. Thus, the story which I "thought of as a big scoop", scoffs Kloor, "wouldn't pass Journalism 101." Kloor then goes on to take, essentially, the entire "herd-like media coverage" of the story to task for repeating the story in a "similarly sensationalist" fashion. The upshot is that Keith Kloor is the man to trust when it comes to environmental journalism, the veritable watchdog of the industry. Sadly, Kloor's sloppiness - driven by his hostility toward what he calls ' ...
