Scientists uncover first tremendous salty subglacial lakes in Canadian Arctic
An evaluation of radar information led scientists to an sudden discovery of two lakes positioned beneath 550 to 750 meters of ice beneath the Devon Ice Cap, one of many largest ice caps within the Canadian Arctic. They’re considered the … Continue reading

Biogeochemistry: Warmer Arctic weakens vegetation
Nature Geoscience 10, 543 (2017). doi:10.1038/ngeo2989 Author: Ana Bastos Warm conditions in the Arctic Ocean have been linked to cold mid-latitude winters. Observations and simulations suggest that warm Arctic anomalies lead to a dip in CO2 uptake capacity in North … Continue reading
Massive craters formed by methane blow-outs from the Arctic sea floor
Crater in Yamal Peninsula in Siberia A new study in Science shows that hundreds of massive, kilometer-wide craters on the ocean floor in the Arctic were formed by substantial methane expulsions. Even though the craters were formed some 12,000 years … Continue reading
Methane seeps in the Canadian high Arctic
Widespread methane leakage from the sea floor Cretaceous climate warming led to a significant methane release from the seafloor, indicating potential for similar destabilization of gas hydrates under modern global warming. A field campaign on the remote Ellef Ringnes Island, … Continue reading
Climate science: Far-flung effects of Arctic warming
Nature Geoscience 10, 253 (2017). doi:10.1038/ngeo2924 Author: James A. Screen Arctic warming affects weather and climate thousands of miles to the south. Scientists are split on how large this effect is. Nature Geoscience – Issue – nature.com science feeds
Rapid Arctic warming has in the past shifted Southern Ocean winds
Ice core records from the two poles show that during the last ice age, sharp spikes in Arctic temperatures shifted the position of winds around Antarctica. Geology News — ScienceDaily
Arctic gives clues on worst mass extinction of life
A fossil of a typical crinoid, showing (from bottom to top) the stem, calyx, and arms with cirri 96 percent of marine species, and 70 percent of terrestrial life died off in the permian-triassic extinction event, as geologists know it. … Continue reading
