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

- Emissions of different states are generated in...on September 30, 2022 at 3:01 pm
Mode changing is an emission phenomenon where the mean pulse profile abruptly changes between two or sometimes more stable states. In theory, the changes of the current flow in the inner acceleration region or pulsar magnetosphere geometry can result in mode changing.
- Marine ice sheets were decisive in acceleration...on September 30, 2022 at 12:56 pm
The intensity and rate of melt during the penultimate ice melting was much higher than previously thought, according to a study published in the journal Nature Communications. According to conclusions of the study, in this climate change scenario, the instability of marine-based ice sheets—those that flow directly into the ocean—was instrumental in accelerating global warming.
- Scientists find link between fast-melting Arctic...on September 29, 2022 at 8:41 pm
An international team of researchers have sounded new alarm bells about the changing chemistry of the western region of the Arctic Ocean after discovering acidity levels increasing three to four times faster than ocean waters elsewhere.
- Observations confirm model predictions of...on September 29, 2022 at 6:00 pm
Rising sea levels from melting glaciers and ice sheets pose an increasing threat to coastal communities worldwide. A new analysis of high-resolution satellite observations takes a major step forward in assessing this risk by confirming theoretical predictions and computational models of sea-level changes used to forecast climate-change-driven impacts.
- Receding ice leaves Canada's polar bears at...on September 29, 2022 at 8:18 am
Sprawled on rocky ground far from sea ice, a lone Canadian polar bear sits under a dazzling sun, his white fur utterly useless as camouflage.
