The Arctic’s on fire and now it’s going to be hit by a heat wave

Things aren't looking good.

JUL 27, 2019, 10:20 AM

Europe’s historic heat wave is heading north this weekend, to the relief of the continent, but its path will send it right towards the Arctic — where it could speed up the melting of sea ice and coincide with devastating wildfires.

Unprecedented wildfires are currently raging across the Arctic Circle, with some the size of 100,000 football fields — so big they can be seen from space. Arctic sea ice is moreover already running at a record low this year; scientists worry a heat wave will only further exacerbate the area’s problems.

One week after the United States saw record-shattering high temperatures, the same fate befell Europe. On Thursday, Paris saw temperatures of 108.7 degrees Fahrenheit (42.6 degrees Celsius), a record high, with Belgium, Germany, and the Netherlands also facing their own record days. The sweltering weather is the result of a heat dome that has allowed hot air to come north from the Sahara Desert, all while blocking cooler air from reaching people.

July is typically a warm month in much of the northern hemisphere, but climate scientists have connected the uptick in dangerously hot temperatures to global warming, with future years set to be much worse.

Europe’s heat wave is about to bake the Arctic

Concerns grow regarding sea ice and Greenland’s ice sheet.

By Andrew Freedman July 26 at 12:12 PM

On Friday, more temperature records are falling in Europe as the historic heat wave that brought the hottest weather ever recorded in Paris, London, the United Kingdom, Belgium, the Netherlands and Germany shifts northward. In a few days, the weather system responsible for the heat wave will stretch all the way across the top of the globe.

It’s what this system, characterized by a strong area of high pressure aloft — often referred to as a heat dome — will do to the Arctic that has some scientists increasingly concerned.

Norway, Sweden and Finland will experience unusually high temperatures through the weekend, as a potentially record strong area of high pressure in the mid-levels of the atmosphere sets up over the region, blocking any cold fronts or other storm systems from moving into the area, like a traffic light in the sky.

Temperatures in parts of Scandinavia will reach into the 90s or higher, on the heels of an intense heat wave in 2018 that led to an outbreak of damaging wildfires.
