polar : (a) of or relating to a geographic pole or the region around it (b) coming from or having the characteristics of such a region — Webster
Polar regions of Earth also known as Earth’s frigid zones, are the regions of Earth surrounding its geographical poles (the North and South Poles). These regions are dominated by Earth’s polar ice caps, the northern resting on the Arctic Ocean and the southern on the continent of Antarctica. — Wikipedia

Warmer winters mean more rain on the Svalbard...
on December 13, 2018 at 2:50 pm
It's often said that the Arctic is one of the places most vulnerable to climate change. Temperatures are climbing faster there than anywhere else on the planet. Increasing winter temperatures mean increasing amounts of rain instead of snow, and scientists are still working to understand exactly what this means on the ground. […]
New climate model to be built from the ground up
on December 13, 2018 at 12:50 pm
Facing the certainty of a changing climate coupled with the uncertainty that remains in predictions of how it will change, scientists and engineers from across the country are teaming up to build a new type of climate model that is designed to provide more precise and actionable predictions. […]
Arctic Report Card tracks region's environmental...

NOAA's annual report card on the Arctic, released today at the American Geophysical Union fall meeting in Washington, D.C., measures the changing climate of the polar region including warmer air and ocean temperatures and declines in sea-ice that are driving shifts in animal habitats. […]
Scary warming at poles showing up at weird times,...

Scientists are seeing surprising melting in Earth's polar regions at times they don't expect, like winter, and in places they don't expect, like eastern Antarctica. […]
ICESat-2 reveals profile of ice sheets, sea ice,...
on December 11, 2018 at 4:16 pm
Less than three months into its mission, NASA's Ice, Cloud and land Elevation Satellite-2, or ICESat-2, is already exceeding scientists' expectations. The satellite is measuring the height of sea ice to within an inch, tracing the terrain of previously unmapped Antarctic valleys, surveying remote ice sheets, and peering through forest canopies and shallow coastal waters.
