The Arctic climate is rapidly and dramatically changing, with continued warming of the air, land and sea. That’s according to the 2019 Arctic Report Card from NOAA.
“This was the second-warmest year on record in the Arctic,” said Emily Osborne, a climate scientist with NOAA. “And to add to that, (the) last five years have been the warmest on record.”
Just what exactly is permafrost? And what is happening now that it’s warming up? To find out, we enter the Arctic Circle’s secret world of ice and frozen history.
Still melting – and melting fast. That’s the basic take-away from the federal government’s annual Arctic Report Card. It finds that Arctic ocean temperatures are increasing and sea ice is declining at the fastest rate in at least 1500 years.
This year was 6.3 degrees Fahrenheit hotter than 1900. Also, water temperatures in the Arctic were 9 degrees Fahrenheit higher than the recent average.
It’s not proven, but the evidence is growing, the report’s chief author said, that a warming Arctic is making the jet stream waver more and delivering more erratic weather patterns to the Lower 48 states, Europe and Russia.
