Small birds almost overheat while feeding their young
For decades, researchers have thought that access to food determined the brood size of birds. Now, biologists have discovered a completely new explanation: the body temperature of small birds can increase by more than 4°C to exceed 45°C when they are feeding their young. Larger broods would require more work, resulting in even higher body temperatures -- something the birds would probably not survive.

Traditional knowledge sheds light on changing East Greenland climate and polar bear hunt
Inuit polar bear hunters in East Greenland report changes to their subsistence hunting patterns as well as polar bear distribution and behavior due to decreasing sea ice and the introduction of hunting quotas in 2006. The study is the first in nearly 20 years to document traditional knowledge in East Greenland -- providing a valuable baseline for monitoring future changes and the polar bear population.

Tiny satellite's first global map of ice clouds
Looking at Earth from the International Space Station, astronauts see big, white clouds spreading across the planet. They cannot distinguish a gray rain cloud from a puffy white cloud. While satellites can see through many clouds and estimate the liquid precipitation they hold, they can't see the smaller ice particles that create enormous rain clouds.

Atlantic Ocean Circulation at weakest point in 1,600 years
New research provides evidence that a key cog in the global ocean circulation system hasn't been running at peak strength since the mid-1800s and is currently at its weakest point in the past 1,600 years. If the system continues to weaken, it could disrupt weather patterns from the United States and Europe to the African Sahel, and cause more rapid increase in sea level on the US East Coast.

Silent marine robots record sounds underwater
Silent marine robots that record sounds underwater are allowing researchers to listen to the oceans as never before. While pilot whales make whistles, buzzes and clicks, pods of hunting dolphins create high-pitched echolocation clicks and larger species such as sperm whales make louder, slower clicks. As well as eavesdropping on marine life, the recordings can be used to measure sea-surface wind speed and monitor storms. The research will be presented at the General Assembly of the European Geosciences Union, Vienna.
