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

Climate scientists at the Nanyang Technological University, Singapore (NTU, Singapore) have extended the known record of Singapore's sea level to almost 10,000 years ago, providing a more robust dataset to aid future predictions of sea level rise.

Under global warming, tipping elements in the Earth system can destabilize each other and eventually lead to climate domino effects. The ice sheets on Greenland and West Antarctica are potential starting points for tipping cascades, a novel network analysis reveals. The Atlantic overturning circulation would then act as a transmitter, and eventually elements like the Amazon rainforest would be impacted. The consequences for people would reach from sea-level rise to biosphere degradation.

For birds and other wildlife, winter is a time of resource scarcity. Extreme winter weather events such as a polar vortex can push some species to the edge of survival. Yet winter tends to get short shrift in climate change research, according to UW-Madison forest and wildlife ecology Professor Ben Zuckerberg.

An international team of researchers, led by the Max Planck Institute for Chemistry in Mainz, Germany, has now succeeded in reconstructing changes in rainfall in Central Asia over the past five million years. The information preserved within the sedimentary succession provides the missing link for understanding land-water feedbacks for global climate.

Icebergs crumbling into the sea may be what first come to mind when imagining the most dramatic effects of global warming.
