End-of-summer Arctic sea ice extent is eighth lowest on record
Sep 21, 2017 (SPX)
Arctic sea ice, the layer of frozen seawater covering much of the Arctic Ocean and neighboring seas, is often referred to as the planet's air conditioner: its w...
Impact of Arctic amplification on East Asian winter climate
Sep 21, 2017 (SPX)
Since 1990, a significant winter cooling trend has occurred in the midlatitudes, including western Siberia, where cold air activity in East Asia originates. Sim...
Researchers take on atmospheric effects of Arctic snowmelt
Sep 21, 2017 (SPX)
The research, led by chemistry professor William R. Simpson, is concerned with the Arctic's reactive bromine season, which is the period of time when bromine is...
Maiden mid-air refuel ensures supplies to Antarctic research station
Sep 20, 2017 (AFP)
The new delivery mode means cargo can be parachuted year-round to scientists. Previously they had to wait up to two weeks for supplies to be shipped in by sea, ...
Study shows Arctic sea ice continues to melt considerably
Sep 15, 2017 (UPI)
Scientists from the Alfred Wegener Institute, the University of Bremen and Universitat Hamburg reported Friday that the minimum sea ice extent for 2017 is avera...
Navy deploys buoys in Arctic for climate research
Sep 14, 2017 (UPI)
The mission, announced Wednesday by the Navy, was a joint effort to collect oceanographic and temperature data for environmental modeling purposes. The research...
Bleak outlook for Asian glaciers
Sep 13, 2017 (AFP)
This is a best-case scenario, based on the assumption that the world manages to limit average global warming to 1.5 degrees Celsius (2.7 degrees Fahrenheit) ove...
Reindeer grazing protects tundra plant diversity in a warming climate
Sep 13, 2017 (SPX)
"By eating tall and wide-leaved plants, reindeer can increase light availability and thus allow more plant species to co-exist and benefit from warmer condition...
Ancient tree exposes cause of hike in Arctic temperature
Sep 12, 2017 (UPI)
The 30,000-year-old kauri tree in a peat swamp in New Zealand showed a new mechanism that could explain how temperatures in the Northern Hemisphere spiked sever...
Warm Antarctic caves harbour secret life: scientists
Sep 08, 2017 (AFP)
The caves, hollowed out by steam from active volcanoes, are light and could reach temperatures of 25 degrees Celsius (77 Fahrenheit), researchers said, raising ...
Experts call for added focus on the impact of glacier mass loss on downstream systems
Sep 07, 2017 (SPX)
Although the impact of melting glaciers on sea levels has received much attention to date, this 'perspectives' paper outlines other multiple downstream effects ...
Massive Antarctic volcanic eruptions linked to abrupt Southern hemisphere climate changes
Sep 07, 2017 (SPX)
"Detailed chemical measurements in Antarctic ice cores show that massive, halogen-rich eruptions from the West Antarctic Mt. Takahe volcano coincided exactly wi...
NASA scientists seek to improve sea ice predictions
Sep 04, 2017 (SPX)
NASA researchers are working to improve their forecasts of the size of the Arctic sea ice cover at the end of the summer melt season - but the goal is not just ...
Record-low 2016 Antarctic sea ice due to 'perfect storm' of tropical, polar conditions
Sep 04, 2017 (SPX)
A dramatic drop in Antarctic sea ice almost a year ago, during the Southern Hemisphere spring, brought its maximum area down to its lowest level in 40 years of ...
What changes when you warm the Antarctic Ocean just 1 degree
Sep 04, 2017 (SPX)
"I was quite surprised," says Gail Ashton of the British Antarctic Survey and Smithsonian Environmental Research Center. "I wasn't expecting a significant obser...
Warming the Antarctic 1 C vastly changes seabed life
Aug 31, 2017 (AFP)
The findings of a field study designed to mimic real-world conditions in a warming ocean were published in the journal Current Biology. The experiments, underta...
New findings on the past and future of sea ice cover in the Arctic
Aug 30, 2017 (SPX)
Prognoses for the future of the Arctic can only be as reliable as the models and data they're based on. The scenarios projected by climate modellers vary greatl...
Methane hydrate is not a smoking gun in the Arctic Ocean
Aug 23, 2017 (SPX)
According to the hypothesis this melt can happen in a time span of a human life, dissociating vast amounts of hydrate and releasing methane into the atmosphere....
Satellite photos reveal gigantic outburst floods
Aug 23, 2017 (SPX)
