Michigan Tech researchers contend that tobacco farmers could increase profits by converting their land to solar farms, which in turn provides renewable energy generation.

In Gobbler's Knob, Pennsylvania, at the crack of dawn today, the nation's most famous groundhog Punxsutawney Phil saw his shadowoffsite link and, as the legend has it, six more weeks of winter.

Tropical forests all over the world are at risk. Two of the main threats are the deforestation for arable land and climate change. Scientists from Technical University of Munich (TUM) and Thünen-Institute compared the losses due to deforestation with those that would result in extreme climate change scenarios in Ecuador. Although global warming is likely to change the distribution of species, deforestation will result in the loss of more dry forests than predicted by climate change damage.

The remnants of Tropical Cyclone Fehi brought rain to New Zealand before it fizzled out. NASA and the Japan Aerospace Exploration Agency’s GPM core satellite provided a look at the rainfall from its vantage point in space.

Some of the smallest creatures on the planet — zooplankton — make the most widespread vertical migration of biomass on Earth. Billions of these animals move deeper into the ocean and away from the light during the day to avoid predators, and migrate up again in the dark of night to feed.

Tropical Cyclone Cebile was still a powerful hurricane in the Southern Indian Ocean when NASA-NOAA's Suomi NPP satellite passed overhead and captured a visible image of the storm. 

A new study finds polar bears in the wild have higher metabolic rates than previously thought, and as climate change alters their environment a growing number of bears are unable to catch enough prey to meet their energy needs.

When Arctic permafrost soil thaws, greenhouse gases are released into the atmosphere, but most of the carbon currently escaping from lakes in northern Alaska is relatively young, according to a new study led by researchers at the University of California, Irvine. Findings paint less dire climate picture, as ancient emissions are more harmful.

Continental shelves are an increasing global sink for atmospheric carbon dioxide.

University of Wyoming researchers led a climate study that determined recent temperatures across Europe and North America appear to have few, if any, precedent in the past 11,000 years.
