Coral records suggest that recent El Nino activity rises above noisy background
By examining a set of fossil corals that are as much as 7,000 years old, scientists have dramatically expanded the amount of information available on the El Nino-Southern Oscillation, a Pacific Ocean climate ...
What caused a giant arrow-shaped cloud on Saturn's moon Titan?
(PhysOrg.com) -- Why does Titan, Saturn's largest moon, have what looks like an enormous white arrow about the size of Texas on its surface?
Takeoffs and landings cause more precipitation around major airports
Researchers have found that areas near commercial airports sometimes experience a small but measurable increase in rain and snow when aircraft take off and land under certain atmospheric conditions.
Mystery dissolves with calcium pump discovery
Geo-microbiologists from Arizona State University have solved a long-standing conundrum about how some photosynthetic microorganisms, endolithic cyanobacteria, bore their way into limestone, sand grains, mussel ...
No-win situation for agricultural expansion in the Amazon, research says
The large-scale expansion of agriculture in the Amazon through deforestation will be a no-win scenario, according to a new study. Published today in the journal Environmental Research Letters, it shows that d ...
NASA study projects warming-driven changes in global rainfall (w/ Video)
(Phys.org) —A NASA-led modeling study provides new evidence that global warming may increase the risk for extreme rainfall and drought.
Rising temperature difference between hemispheres could dramatically shift rainfall patterns in tropics
(Phys.org) —One often ignored consequence of global climate change is that the Northern Hemisphere is becoming warmer than the Southern Hemisphere, which could significantly alter tropical precipitation ...
Striking gold: Earthquakes deposit precious metal
Solid gold can be deposited in Earth's crust "almost instantaneously" during earthquakes, said a study published in the journal Nature Geoscience on Sunday.
Ozone depletion trumps greenhouse gas increase in jet-stream shift
Depletion of Antarctic ozone is a more important factor than increasing greenhouse gases in shifting the Southern Hemisphere jet stream in a southward direction, according to researchers at Penn State.
Plants adapt to drought but limits are looming, study finds (Update)
Scientists with the U.S. Department of Agriculture, or USDA, and their partners have determined that water demand by many plant communities can fluctuate in response to water availability, indicating a capacity ...
What dust may have to do with Earth's rapidly warming poles
(Phys.org)—As earth's climate warms, scientists have tried to understand why the poles are heating up two to three times faster than the rest of the planet. Airborne dust, it turns out, may play a key role.
More ice loss through snowfall on Antarctica
Stronger snowfall increases future ice discharge from Antarctica. Global warming leads to more precipitation as warmer air holds more moisture – hence earlier research suggested the Antarctic ice sheet ...
A 3.45-billion-year-old diet
Researchers are providing new information about the 'diet' of microorganisms on the early Earth. By studying 3.45-billion-year-old rocks, the team uncovered clues about ancient microbial metabolism.
Himalayan glaciers will shrink even if temperatures hold steady, study says
(Phys.org)—Come rain or shine, or even snow, some glaciers of the Himalayas will continue shrinking for many years to come.
