UN report finds temperature rise is ‘locked in’ for Arctic (via the Hill)

The Arctic is now “locked in” to experiencing unnatural levels of temperature rise by as early as 2050, according to a new United Nations environmental report out Wednesday.

Dramatic temperature increases in the globe’s northernmost region, which is typically covered by permafrost, is unavoidable, according to the report released at the United Nations Environment Assembly.

Even if countries were to meet the original goals of the Paris climate agreement, it would do nothing to stop Arctic winter temperatures from increasing 3 to 5 degrees Celsius by 2050 and 5 to 9 degrees Celsius by 2080, according to the report.

The resulting sea level rises worldwide would be devastating.

The report also warned that the rapid thawing of permafrost in the region could likely accelerate the effects of climate change, which could completely negate any long–term international pacts and goals to limit global warming to 2 degrees Celsius compared to 1986–2005 levels.
