Do you recall the big Arctic melting records of 2005 and 2007? Probably you do. Scientists had noticed the Arctic ice was on a declining trend and predicted this would continue under expected climate change. But no one expected the … Continue reading
Birches can’t hurt the climate. They’re made of carbon and – just to be sure – they’re even painted white! Well, at least on the Swedish tundra that’s no guarantee…
Carbon stored in Arctic tundra could be released into the atmosphere by new trees growing in the warmer region, exacerbating climate change, scientists have revealed.
The Arctic is getting greener as plant growth increases in response to a warmer climate. This greater plant growth means more carbon is stored in the increasing biomass, so it was previously thought the greening would result in more carbon dioxide being taken up from the atmosphere, thus helping to reduce the rate of global warming.
The dramatic melt-off of Arctic sea ice due to climate change is hitting closer to home than millions of Americans might think.
In just a few decades shrubs in the Arctic tundra have turned into trees as a result of the warming Arctic climate, creating patches of forest which, if replicated across the tundra, would significantly accelerate global warming.
It has been know for some time that large quantitites of methane lie hidden in reservoirs under the permafrost layers on the tundra and in clathrates on the continental shelve. It is neither a secret that those large quantities of … Continue reading
