Methane in the Arctic Circle

Methane In conditions without oxygen, such as at the bottom of a lake orthe sea, decomposition turns organic matter into methane, rather than carbon dioxide. Large increases in methane emissions would be a grave concern, because methane is 25 times moreeffective at warming the planet than carbon dioxide (over a 100 year time scale). Lakes,…

NASA: Projected U.S. Temperature Changes by 2100

NASA: The average temperature across the continental U.S. could be 8 degrees Fahrenheit warmer by the end of the 21st century under a climate scenario in which concentrations of the greenhouse gas carbon dioxide rise to 800 parts per million. Current concentrations stand at 400 parts per million, and are rising faster than at any…

Antarctic Methane Emissions

METOP-2 imagery reveals that there is a significant area of high methane concentration over Antarctica. A study paper from 2012 reported that as glaciers melt, gas could belch into atmosphere. Potential Methane Reservoirs Beneath AntarcticaAug. 29, 2012 — The Antarctic Ice Sheet could be an overlooked but important source of methane, a potent greenhouse gas,…
