As Walter Meier of NASA’s Goddard Space Flight Center has put it, “The climate system’s interconnected.
So what happens in the Arctic doesn’t stay in the Arctic.” That’s true for a number of reasons, including this: Research suggests that Arctic warming is affecting day-to-day weather much farther south — not always pleasantly.

It focuses on spectacular visuals related to the science of our planet, with an emphasis (although not an exclusive one) on the unfolding Anthropocene Epoch.
The report finds that the current rate of Arctic warming is unprecedented in at least the past 2,000 years.
And the pace of Arctic sea ice loss experienced in the past few decades has not been seen in at least the past 1,450 years.
What is it made of and what is the typical wall thickness of this amazing auger?There are also implications for fisheries, ships and naval submarines having to dodge ice floes — and geopolitics as well.Melting sea ice has already turned the region into a new frontier, with nations eyeing its sea routes, strategic position between Eurasia and North America, and potentially huge reserves of oil and gas.From this year’s Arctic Report Card, an assessment published every year by the U. National Oceanic and Atmospheric Administration: Despite relatively cool summer temperatures, observations in 2017 continue to indicate that the Arctic environmental system has reached a ‘new normal’, characterized by long-term losses in the extent and thickness of the sea ice cover, the extent and duration of the winter snow cover and the mass of ice in the Greenland Ice Sheet and Arctic glaciers, and warming sea surface and permafrost temperatures.
“The Arctic is going through the most unprecedented transition in human history, and we need better observations to understand and predict how these changes will affect everyone, not just the people of the north,” said Jeremy Mathis, director of NOAA’s Arctic Research Program.
It’s a common refrain doubters of human-caused global warming: Temperatures now are no higher than they were during the Medieval Warm Period from about 800 to 1400 AD.
