Mysterious 'Magic Island' appears on Saturn's moon Titan
Now you don't see it. Now, you do. And now you don't see it again. Astronomers have discovered a bright, mysterious geologic object – where one never existed – on Cassini mission radar images of Ligeia ...
New evidence that cosmic impact caused Younger Dryas extinctions
Long-term warming likely to be significant despite recent slowdown
A new NASA study shows Earth's climate likely will continue to warm during this century on track with previous estimates, despite the recent slowdown in the rate of global warming.
Atlantic currents have seen 'drastic' changes: study
Scientists have found evidence of a "drastic" shift since the 1970s in north Atlantic Ocean currents that usually influence weather in the northern hemisphere, Swiss researchers said on Tuesday.
Climate change to continue to year 3000 in best case scenarios: research
New research indicates the impact of rising CO2 levels in the Earth's atmosphere will cause unstoppable effects to the climate for at least the next 1000 years, causing researchers to estimate a collapse of the West Antar ...
'Time running out' as CO2 levels hit new high, UN says
Atmospheric carbon dioxide concentrations have crossed a new threshold, the UN's weather agency said Monday, highlighting the urgency of curbing manmade, climate-altering greenhouse gases.
Slowdown of global warming fleeting
The recent slowdown in the warming rate of the Northern Hemisphere may be a result of internal variability of the Atlantic Multidecadal Oscillation—a natural phenomenon related to sea surface temperatures, ...
Wind and rain belts to shift north as planet warms, research says
As humans continue to heat the planet, a northward shift of Earth's wind and rain belts could make a broad swath of regions drier, including the Middle East, American West and Amazonia, while making Monsoon ...
Northern hemisphere losing last dry snow region, says study
(Phys.org) —Last July, something unprecedented in the 34-year satellite record happened: 98 percent of the Greenland Ice Sheet's surface melted, compared to roughly 50 percent during an average summer. ...
Location of upwelling in Earth's mantle discovered to be stable
A study published in Nature today shares the discovery that large-scale upwelling within Earth's mantle mostly occurs in only two places: beneath Africa and the Central Pacific. More importantly, Clinton Conrad ...
Atmospheric carbon levels nearing historic threshold
(Phys.org) —For the first time in human history, concentrations of the greenhouse gas carbon dioxide (CO2) could rise above 400 parts per million (ppm) for sustained lengths of time throughout much of the Northern Hemisphere ...
How the ice ages ended
A study of sediment cores collected from the deep ocean supports a new explanation for how glacier melting at the end of the ice ages led to the release of carbon dioxide from the ocean.
High-Arctic heat tops 1,800-year high, says study
(Phys.org)—Summers on the Norwegian archipelago of Svalbard are now warmer than at any other time in the last 1,800 years, including during medieval times when parts of the northern hemisphere were as hot ...
Northern hemisphere summers warmest in 600 years (Update)
Harvard researchers are adding statistical nuance to our understanding of how modern and historical temperatures compare.
