The forecasting tool IceNet promises to be a useful tool for evaluating sea ice loss in the Arctic. But ethical and logistic considerations have to be taken before scientific and Indigenous communities start working together.
If climate change throws off the seasonal freeze-thaw cycle of Arctic sea ice, it could trigger a reinforcing cycle of sea ice melt in parts of the Canadian Arctic.
Estas intensas tormentas marítimas suponen una amenaza para las comunidades costeras y las actividades económicas de las altas latitudes y puede que influencien el clima y la circulación oceánica.
Last winter, an unprecedented high-pressure system over the Arctic drove nearly a quarter of old sea ice into warmer waters, putting it at greater risk of melting.
These intense maritime storms pose threats to high-latitude coastal communities and economic activities and may influence climate and ocean circulation.
The Siberian river’s creation caused a massive influx of fresh water into the Kara Sea and radically changed the Arctic Ocean and Earth’s climate.
Over a 13-year period, almost a thousand flights surveyed land and sea ice across the Arctic, Antarctic, and Alaska, providing unique insights into how the polar regions are changing.
Claire L. Parkinson was awarded the 2020 Roger Revelle Medal at the virtual AGU Fall Meeting in December. The medal is for “outstanding contributions in atmospheric sciences, atmosphere-ocean coupling, atmosphere-land coupling, biogeochemical cycles, climate or related aspects of the Earth system.”
An ongoing project in northern Alaska is using pulses of laser light to monitor anthropogenic activity, ice quakes, and marine wildlife.
