But the melting polar ice sheet is opening up potentially major shipping routes, and untapped reserves of oil, gas and minerals will become increasingly accessible, leading Russia and China to show mounting interest in the region.
"Hundreds of thousands of years ago, the area was a massive polar ice sheet, with walls of ice kilometres high, where woolly mammoth and strait-tusked elephants wandered with sabre-toothed cats, bison and giant short-faced bears.
It details the historical and current context and what it accomplished; the human element, including training young scientists, increasing diversity, engaging polar residents and building community capacity, communicating with the public, and providing resources for teachers; advances and discoveries relating to polar ice sheet science and subglacial systems, sea ice vulnerability and connections to society, marine ecosystems and global warming, polar atmospheric observations and lower latitude impacts, geospace and space weather, terrestrial earth systems and permafrost, evidence of past climate change, human health, and other areas; the impact of IPY on tools used for polar research; and the need to translate scientific knowledge into actionable information.
Dr David Vaughan from the British Antarctic Survey will discuss difficulties involved in estimating the contribution of polar ice sheet melting to sea level rise.
The study combined observations from 10 different satellite missions to develop the first consistent measure of polar ice sheet changes.
Sheet Mass Balance Inter-comparison Exercise (IMBIE) -- that combined observations from 10 satellite missions to develop the first consistent measurement of polar ice sheet changes.
His work examining sediment cores from Antarctica's seafloor indicates if the planet were two to three degrees warmer, it would have a dramatic effect on the polar ice sheet.
Furthermore, warming oceans are causing polar ice sheets to melt faster, which will make sea levels rise even more.

These feedbacks are: permafrost thaw, loss of methane hydrates from the ocean floor, weakening land and ocean carbon sinks, increasing bacterial respiration in the oceans, Amazon rainforest dieback, boreal forest dieback, reduction of northern hemisphere snow cover, loss of Arctic summer sea ice, and reduction of Antarctic sea ice and polar ice sheets.
