This article discusses the heat waves occurring in the Arctic, and their cause – human-released GHGs. A heat wave 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.
It is a classic prediction of climate theory that’s playing out more vividly than ever before.
