Curiosity providing new weather and radiation data about Mars
(Phys.org)—Observations of wind patterns and natural radiation patterns on Mars by NASA's Curiosity rover are helping scientists better understand the environment on the Red Planet's surface.
North Atlantic 'Achilles heel' lets upper atmosphere affect the abyss
A University of Utah study suggests something amazing: Periodic changes in winds 15 to 30 miles high in the stratosphere influence the seas by striking a vulnerable "Achilles heel" in the North Atlantic and ...
Link between air pollution and cyclone intensity in Arabian Sea
Pollution is making Arabian Sea cyclones more intense, according to a study in this week's issue of the journal Nature.
Researchers find possible explanation of early Polynesian migration
New scientific review investigates potential influences on recent UK winter floods
A comprehensive review of all potential factors behind the 2013/2014 UK winter floods is published today in the journal Nature Climate Change. The paper does not definitively answer whether human activity played ...
When tectonics killed everything
A new paper reveals how the worst extinction in Earth's history may have been tied to the formation of Supercontinent Pangea. The catastrophe wasn't triggered by an impact from above—unlike another well-known ...
Ozone hole might slightly warm planet
A lot of people mix up the ozone hole and global warming, believing the hole is a major cause of the world's increasing average temperature. Scientists, on the other hand, have long attributed a small cooling ...
Researchers contend increase in Antarctic sea ice due to summer melt
Study suggests real-world generating capacity of wind farms at large scales has been overestimated
Research by Harvard professor David Keith suggests that the global capacity for energy generation from wind power has been overestimated, and that geophysical / climate effects of turbines will reduce the ...
Antarctic ice core contains unrivaled detail of past climate
A team of U.S. ice-coring scientists and engineers in Antarctica, funded by the National Science Foundation (NSF), have recovered from the ice sheet a record of past climate and greenhouse gases in the atmosphere ...
Super-TIGER balloon breaks records while collecting data
(Phys.org)—A large NASA science balloon has broken two flight duration records while flying over Antarctica carrying an instrument that detected 50 million cosmic rays.
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.
New model reveals how huddling penguins share heat fairly
Penguins that face the bitter cold and icy winds of Antarctica often huddle together in large groups for warmth during storms. Mathematicians at the University of California, Merced created a model of penguin ...
