UN warns El Nino likely by end of year
The "El Nino" phenomenon, which sparks climate extremes around the globe, is likely to take hold in the Pacific Ocean by the end of the year and could even do so within weeks, the UN said on Thursday.
Maternal effect key to fish combating climate change
(Phys.org) —According to research by Western scientists, thermal tolerance in a wild fish population is a key factor in understanding how animal species adapt to climate change.
New techniques inspired by nature for accelerated aging and chemical extraction of mineral ores
Nature writ large is filled with examples of transformative chemical reactions that take place in the solid state—minerals found deep underground or on the surface of the earth that undergo chemical reactions over time ...
Central Valley sees big drop in wintertime fog needed for fruit and nut crops
California's winter tule fog—hated by drivers, but needed by fruit and nut trees—has declined dramatically over the past three decades, raising a red flag for the state's multibillion dollar agricultural ...
Shrub growth decreases as winter temperatures fluctuate up
Many have assumed that warmer winters as a result of climate change would increase the growth of trees and shrubs because the growing season would be longer. But shrubs achieve less yearly growth when cold ...
Changing temperature powers sensors in hard-to-reach places
A centuries-old clock built for a king is the inspiration for a group of computer scientists and electrical engineers who hope to harvest power from the air.
Engineers design video game controller that can sense players' emotions (w/ video)

A full-spectrum Mars simulation in a box
There are many reasons why Mars excels at destroying expensive equipment. For one thing, its entire surface is made of partially-magnetized dust. For another, Mars possesses just enough atmosphere so that ...
Researchers predict more runoff in High Asia due to increasing precipitation and glacier melt
Climate change to increase forest fire danger in Europe
Climate change is expected to bring increased temperatures and longer droughts—conditions that will make forests more susceptible to fires.
Winter heatwaves are nice, as extreme weather events go
If you've stepped outside at lunchtime in Sydney over the past few days, you'd be forgiven for thinking that it was more like early summer than the beginning of winter.
Forecasting temperature extremes with ozone
For the past two summers, Australians have sweated through record heat waves, with thermometers climbing as high as 118 degrees Fahrenheit in parts of the country. In January, officials were forced to halt ...
A potential candidate for more efficient solid oxide bismuth and iridium fuel cells
(Phys.org) —Fuel cells for decentralized energy production require oxygen ion conductors: materials that can store oxygen as ions, and then transport and release it. German researchers have now found an ...
Snow is largely a no-show for Iditarod Trail Sled Dog Race
On March 1, 65 mushers and their teams of dogs left Anchorage, Alaska, on a quest to win the Iditarod—a race covering 1,000 miles of mountain ranges, frozen rivers, dense forest, tundra and coastline. According ...
