Arctic “death spiral” leaves climate scientists shocked and worried
A truly disturbing article (yet again!) this morning from the Vancouver Observer. Here are some of the words climate scientists have been using recently to describe the recent, unprecedented decline in Arctic sea ice witnessed this past summer: “unprecedented”, “amazing”, “extreme”, “hard to exaggerate”, “incredibly fast”, “death spiral” and “heading for oblivion”.
Here’s an excerpt from the article:
“A “radical shift” is plunging the Arctic Ocean towards an ice-free state for the first time in millions of years. One of the world’s foremost ice experts, Professor Peter Wadhams of Cambridge University, calls it a “global disaster” that will cause such a big boost in global temperatures that even such extreme measures as geo-engineering need to be considered urgently.
“This jaw-dropping acceleration of Arctic sea ice collapse is completely out-stripping the worst case scenarios of the UN International Panel on Climate Change (IPCC). The IPCC reports are the primary source of climate science used by world leaders, policy makers, businesses and citizens to decide the urgency and level of action needed.
“A recent CBC report on these CryoSat-2 results was blunt: “Arctic ice could vanish in 10 years, scientists warn … Arctic sea ice is melting at a pace so much faster than once thought that the latest projections say it might disappear by as soon as 2022.
“Pumping ever more carbon into our economy, while ignoring most of it when making policy decisions, seems increasingly reckless. It increases the pace of climate change while also increasing our economy’s exposure to carbon risk.”
