Here’s another climate change video from the BBC re the loss of permafrost in the Russian Arctic. The result is catastrophic as entire industries – factories, housing etc – were built on the permafrost and it’s now turning into bogland. This will make the buildings unstable and uninhabitable.
As the permafrost becomes bog, it’s releasing methane – far more dangerous to the climate than mere carbon dioxide. Methane is the gas that scientists fear the most and the gas that was identified as the trigger for the ‘tipping point’ in Al Gore’s An Inconvenient Truth.
