Arctic Heat Surges Again, and Studies Are Finding Climate Change Connections

This article discusses a heat wave that sent temperatures spiking 30 degrees above normal in part of the Arctic, and sea ice is taking a nosedive. That ice loss has scientists worried.

As temperatures at the North Pole approached the melting point this week and the Arctic ice thins toward the vanishing point, new research suggests that the extraordinary records being set year after year are a manifestation of manmade climate change.

One new study, published last week in the journal Weather and Climate Extremes, found that unusual heat that hit the Arctic in 2016 could not have happened without the increases in greenhouse gas emissions since the Industrial Revolution, which has set off a feedback loop of rising temperatures and dwindling sea ice.
