ESA - Space for Our Climate - Signs of Thawing Permafrost Revealed From Space
Now that looks like a “tipping point” we have read about. The methane that gets loose as a result of our activity is worse than our own emissions. Now this is out of control, as much as we might cut our emissions they are replaced by these.
Good luck kids, you are gonna need it.
igns of thawing permafrost revealed from space
27 March 2012
Satellite are seeing changes in land surfaces in high detail at northern latitudes, indicating thawing permafrost. This releases greenhouse gases into parts of the Arctic, exacerbating the effects of climate change.
Permafrost is ground that remains at or below 0°C for at least two consecutive years and usually appears in areas at high latitudes such as Alaska, Siberia and Northern Scandinavia, or at high altitudes like the Andes, Himalayas and the Alps.
About half of the world’s underground organic carbon is found in northern permafrost regions. This is more than double the amount of carbon in the atmosphere in the form of the greenhouse gases carbon dioxide and methane.
The effects of climate change are most severe and rapid in the Arctic, causing the permafrost to thaw. When it does, it releases greenhouse gases into the atmosphere, exacerbating the effects of climate change.
