Greatest warming is in the north, but biggest impact on life is in the tropics
In recent decades documented biological changes in the far Northern Hemisphere have been attributed to global warming, changes from species extinctions to shifting geographic ranges. Such changes were expected because warming ...
Why is the harvest moon so big and orange?
Ever wonder why the moon sometimes looks so big and orange? Professor Emeritus John Percy of the Department of Astronomy and Astrophysics explains the mystery behind the harvest moon:
Landing site for Rosetta going South
Scientists have determined that ESA's Rosetta mission needs to deliver its lander to a site in the southern hemisphere of comet 67P/Churyumov-Gerasimenko. A site in this region will be the safest and most ...
Ocean cooling contributed to mid-20th century global warming hiatus
The hiatus of global warming in the Northern Hemisphere during the mid-20th century may have been due to an abrupt cooling event centered over the North Atlantic around 1970, rather than the cooling effects ...
Spring on Titan brings sunshine and patchy cloud
Titan's northern hemisphere is set for mainly fine spring weather, with polar skies clearing since the equinox in August last year. Cassini’s VIMS instrument has been monitoring clouds on Titan continuously ...
'Archeologists of the air' isolate pristine aerosol particles in the Amazon
Environmental engineers who might better be called "archeologists of the air" have, for the first time, isolated aerosol particles in near pristine pre-industrial conditions.
Diverse fungal root endophytes baffling
No-one but specialists using genetic methods can distinguish one dark septate fungal root endophyte from another. An analysis of their distribution in the northern hemisphere is now available for the first ...
Study adds new clue to how last ice age ended
As the last ice age was ending, about 13,000 years ago, a final blast of cold hit Europe, and for a thousand years or more, it felt like the ice age had returned. But oddly, despite bitter cold winters in ...
Climate: New study slashes estimate of icecap loss
Estimates of the rate of ice loss from Greenland and West Antarctica, one of the most worrying questions in the global warming debate, should be halved, according to Dutch and US scientists.
Variations in fine-structure constant suggest laws of physics not the same everywhere
Earth from space: Giant iceberg enters Nares Strait
ESA's Envisat satellite has been tracking the progression of the giant iceberg that calved from Greenland's Petermann glacier on 4 August 2010. This animation shows that the iceberg, the largest in the northern ...
Researchers find a 'great fizz' of carbon dioxide at the end of the last ice age
Imagine loosening the screw-top of a soda bottle and hearing the carbon dioxide begin to escape. Then imagine taking the cap off quickly, and seeing the beverage foam and fizz out of the bottle. Then, imagine ...
Dwindling green pastures, not hunting, may have killed off the mammoth
(PhysOrg.com) -- A vast reduction in grasslands may have been the primary cause of the decline of mammals such as the woolly mammoth according to Durham University scientists.
Study finds permafrost warming, monitoring improving
Permafrost warming continues throughout a wide swath of the Northern Hemisphere, according to a team of scientists assembled during the recent International Polar Year.
