DESCRIPTION:The Arctic. What pops into your head when you hear those words
 ? Polar\nbears\, icebergs\, freezing temperatures? These days\, you might 
 also\nthink about the declining sea ice\, and the possibility of the\nNort
 hwest Passage opening up for ships. In fact\, the Arctic is warming\ntwice
  as fast as the global average\, so you might associate the Arctic\nwith 
 “warming” as well as “freezing” these days. Higher temperatures\ni
 n the Arctic are likely to cause positive feedbacks with the\ngreenhouse g
 as methane\, as some of its main sources (wetlands and\npermafrost) emit m
 ore at warmer temperatures. This talk will focus on\nthe work of a researc
 h project to investigate methane emissions in the\nArctic (http://arcticme
 thane.wordpress.com/). The Arctic sources are\nnot well known\, so in this
  project measurements of methane were taken\nin summer 2012 and 2013 from 
 the wetland areas of Lapland and from a\nresearch aircraft that flew aroun
 d the region. Modelling work is now\nbeing undertaken to help understand t
 he measurement data.
