UNEP - If Carbon Output Ended Tomorrow, Arctic Would Still Warm By 5C By 2100

A new report from the United Nations shows that it’s basically game over for the Arctic as we know it.

Even if carbon pollution magically stopped tomorrow, the region’s winters would still warm an astonishing 5 degrees Celsius by century’s end. Meeting the Paris Agreement pledges — which do not get us to the two degree warming goal — would lead to that level of warming by midcentury and up to 9 degrees Celsius by 2100, along the way unravelling one of the most fragile ecosystems on the planet and displacing people who have done very little to cause the disruption.

The report was released on Tuesday at a meeting of the United Nations Environment Program. The synthesis pulls together recent research and puts it all in one terrifying graphic-driven document. The litany of changes that have already occurred is unsettling, but the real shock is in what could come next.

The Arctic is warming twice as fast as the rest of the globe, which translates to dramatic change. Sea ice extent, which has shrunk about 40 per cent since regular satellite monitoring began in 1979, could reach zero per cent in summer as early as the 2030s. Old, thick sea ice will likely be gone even sooner.
