Please join us for a free public lecture entitled:
“Methane from Northern Permafrost – A Cause for Concern?”
Speaker: Dr. Rachel Chang
Canada Research Chair in Atmospheric Science
Department of Physics and Atmospheric Science, Dalhousie University
Monday, January 5th, 2015
7:30pm
Museum of Natural History
1747 Summer St., Halifax.
Abstract:
Large areas of northern regions are covered by permafrost. As the Arctic warms, the permafrost will degrade and lead to increased emissions of greenhouse gases such as methane. Recently, global atmospheric methane concentrations have begun to increase again after being stable for a decade, and the Arctic is one of the possible sources. Dr. Chang will outline results from her Arctic research and discuss potential causes that could be contributing to this increase.
