The recent heat wave that baked both Europe and North America also had a major impact on the world’s largest island: temperatures across Greenland spiked during the same time period, causing a major melt event that released 18 billion tons of water over a three-day period, enough to cover the entirety of
In what seems to be an encore to last winter’s disturbing display, temperatures in the Arctic have once again risen above the freezing mark. According to The Woods Hole Oceanographic Institution, the average temperature for the Arctic winter is -40ºF (-40ºC), but instead is currently hovering around 32ºF (0ºC).
Sea ice levels in the Arctic and Antarctic are growing at a record-slow pace this season, according to multiple sources. While this year’s summer low for the northern hemisphere wasn’t as bad as the current record, set in 2012, the autumn rebound is falling well short of both the fall of 2012’s growth rate and the 37-year average. The Antarctic is following suit, with the summer melt shrinking the ice there at a record speeds.
Scientists have detected that the earth’s magnetic field has been significantly weakening over the past six months. Data collated by the European Space Agency (ESA) Swarm satellite array indicates that the field has developed several weak areas over the Western Hemisphere.
Conversely, the field has strengthened in other areas such as the southern Indian Ocean, according to the magnetometers onboard the Swarm satellites.
