Global warming hits ‘tipping point’

Siberia feels the heat.

It’s a frozen peat bog the size of France and Germany combined, contains billions of tonnes of greenhouse gas and, for the first time since the ice age, it is melting.

The researchers found that what was until recently a barren expanse of frozen peat is turning into a broken landscape of mud and lakes, some more than a kilometre across.

Climate scientists yesterday reacted with alarm to the finding, and warned that predictions of future global temperatures would have to be revised upwards.

It’s not just that this area is thawing, it’s the enormous amount of greenhouse gases that will be released as it does, thus speeding global warming even more.
