Global ocean currents explain why Northern Hemisphere is the soggier one
A quick glance at a world precipitation map shows that most tropical rain falls in the Northern Hemisphere. The Palmyra Atoll, at 6 degrees north, gets 175 inches of rain a year, while an equal distance on ...
New records for sea ice loss, greenhouse gas in 2012 (Update 2)
The world lost record amounts of Arctic sea ice in 2012 and spewed out all-time high levels of greenhouse gases by burning fossil fuels, international climate scientists said Tuesday.
Huge solar flare jams radio, satellite signals: NASA
A powerful solar eruption that triggered a huge geomagnetic storm has disturbed radio communications and could disrupt electrical power grids, radio and satellite communication in the next days, NASA said.
Glaciers melting faster than originally thought: study
Food crops damaged by pollution crossing continents
(PhysOrg.com) -- Man-made air pollution from North America causes Europe to lose 1.2 million tonnes of wheat a year, a new study has found.
Wet weather helped human culture grow (Update)
We moan about the wet weather all too often but it may have been crucial in the development of human culture from about 70,000 years onwards, according to scientists reporting in Nature Communications today. ...
Study: Arctic sea ice decline may be driving snowy winters seen in recent years
A new study led by the Georgia Institute of Technology provides further evidence of a relationship between melting ice in the Arctic regions and widespread cold outbreaks in the Northern Hemisphere. The study's ...
Cassini spacecraft reveals clues about Saturn moon
(Phys.org) —NASA's Cassini spacecraft is providing scientists with key clues about Saturn's moon Titan, and in particular, its hydrocarbon lakes and seas.
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 ...
2012: Shadow of the Dark Rift
(PhysOrg.com) -- One of the most bizarre theories about 2012 has built up with very little attention to facts. This idea holds that a cosmic alignment of the sun, Earth, the center of our galaxy -- or perhaps ...
Arctic ice loss amplified Superstorm Sandy violence
(Phys.org) —If you believe that last October's Superstorm Sandy was a freak of nature—the confluence of unusual meteorological, atmospheric and celestial events—think again.
Earth's last warm phase exposed
Analysis of data collected from ice cores and marine sediment cores in both polar regions has given scientists a clearer picture of how the Earth's climate changed during the last Interglacial period. This ...
Earth orbit changes key to Antarctic warming that ended last ice age
For more than a century scientists have known that Earth's ice ages are caused by the wobbling of the planet's orbit, which changes its orientation to the sun and affects the amount of sunlight reaching higher ...
Arctic becoming warmer, greener region with record losses of summer sea ice and late spring snow
The Arctic region continued to break records in 2012—among them the loss of summer sea ice, spring snow cover, and melting of the Greenland ice sheet. This was true even though air temperatures in the Arctic ...
