DESCRIPTION:The Arctic. What pops into your head when you hear those words
 ? Polar bears\, icebergs\, freezing temperatures? These days\, you might a
 lso think about the declining sea ice\, and the possibility of the Northwe
 st Passage opening up for ships. In fact\, the Arctic is warming twice as 
 fast as the global average\, so you might associate the Arctic with “war
 ming” as well as “freezing” these days. Higher temperatures in the A
 rctic are likely to cause positive feedbacks with the greenhouse gas metha
 ne\, as some of its main sources (wetlands and permafrost) emit more at wa
 rmer temperatures. This talk will focus on the work of a research project 
 to investigate methane emissions in the Arctic (http://arcticmethane.wordp
 ress.com/). The Arctic sources are not well known\, so in this project mea
 surements of methane were taken in summer 2012 and 2013 from the wetland a
 reas of Lapland and from a research aircraft that flew around the region. 
 Modelling work is now being undertaken to help understand the measurement 
 data.
