Arctic Methane

Two small paragraphs in the news " Millions of tons of methane will surface in the Arctic " (please, read the news):

i) Methane now accounts for between 4 to 9% of greenhouse , well below the effect of CO2 (from 9 to 26%). However, its ability to absorb heat is about 25 times higher than that of CO2, so its lower contribution to global warming is because there is less of it in the air (while counting some 75 times more CO2 than methane). Conclusion: escaping tons of methane were buried in frozen ground is not going to help improve the situation of climate change.

ii) This was known in recent years (Nature 443, 71-75, 2006: Methane bubbling from Siberian thaw lakes as a positive feedback to climate warming )

From here a greeting to my Jiminy Cricket . ;-)

Republicans and the environment

this weekend asking the singers to Cold Play what was the main problem in the world and their response was clear: the Republicans in the U.S.. Today I found this entry in TreeHugger explaining why. It turns out that Sarah Palin , the newly elected Vice President by the Republicans, it is clear that the first is the economy, who falls. Thus, the future leaders of the world's most powerful country does not believe that climate change due to human action, intends to draw the polar bear from the list of protected species, supports opening the Arctic Animal Reserve for oil and inspections seems to be opposed to any environmental action in your state (Alaska). There has fought back to hunt beluga, has opposed the protection of salmon affected by extensive mining, has opposed restrictions on hunting of wolves and bears from the air and pay $ 150 for each dead wolf delivered to authorities. It only seems concerned with extracting oil, natural gas, gold, zinc and other natural resources to improve the economy and the preservation of jobs.

now understand the components of Cold Play.
