The Last Time There Was This Much CO2, Trees Grew at the South Pole
Distressingly, another study revealed that melting permafrost across the Arctic could now be releasing 12 times as much nitrous oxide as previously thought. Nitrous oxide is an extremely powerful greenhouse gas, 300 times more potent than carbon dioxide, and can remain in the atmosphere for 114 years.
Recent research shows that Canada’s Arctic is now the warmest it has been in 10,000 years, and the temperatures are continuing to climb. Duane Froese, a professor at the University of Alberta and a co-author of the recent study on the topic, told the CBC,
“I would guess we’re getting back over 100,000 years since we’ve seen temperatures at least this warm.”
