Methane feedback</i> in the post <a href="http://arctic-news.blogspot.com/2012/12/how-to-avoid-mass-scale-death-destruction-and-extinction.html" rel="nofollow">How to avoid mass-scale death, destruction and extinction</a>, which also includes some human feedback, e.g. farmers slashing and burning forests in response to crop loss caused by climate change.

Only 2010 came close with 10.99332 million sq. km, while all other years recorded over 11 million sq. km for this day of the year. <br /><br />Methane contributes to this record low in two ways. Firstly, it traps heat in the atmosphere. Furthermore, given that there's so much methane in the atmosphere over the Arctic Ocean, there must additionally be a lot of methane that gets decomposed in the water by methanotrophs. This process generates heat, which warms up the water and makes it more difficult for ice to form.Sam Caranahttps://www.blogger.com/profile/12376449209858411775noreply@blogger.comtag:blogger.com,1999:blog-3046701423623795423.post-89301562027619794922012-12-30T12:31:47.992-08:002012-12-30T12:31:47.992-08:00Methane went up in Jan. of 2012.
