Renewable sources such as solar and wind could supply up to 80 percent of the world's energy needs by 2050 and play a significant role in fighting global warming, a top climate panel concluded Monday. Read more about it here.

Scientists at a major conference on Arctic warming were told Wednesday to use plain language to explain the dramatic melt in the region to a world reluctant to take action against climate change.

Two studies suggest extreme rainstorms and snowfalls have grown substantially stronger, with scientists for the first time finding the telltale fingerprints of man-made global warming on downpours that often cause deadly flooding.

Two studies in Wednesday's issue of the journal Nature link heavy rains to increases in greenhouse gases more than ever before.

Both studies should weaken the argument that climate change is a "victimless crime," said Myles Allen of the University of Oxford. He co-authored the second study, which connected flooding and climate change in the United Kingdom. "Extreme weather is what actually hurts people."

In a sharp challenge to the Obama administration, House Republican leaders intend to unveil legislation to prohibit the Environmental Protection Agency from regulating greenhouse gases, officials said. They expect to advance the bill quickly.

N.C. State has snared $1.8 million to find ways to better predict consequences of climate change.

The money is part of a five year, $10 million National Science Foundation grant that will also fund projects at North Carolina A & T, the University of Tennessee and Northwestern.

At NCSU, researchers will focus on better predicting hurricane and precipitation patterns. Professors Fred Semazzi and Nagiza Samatova will do the work.
Semazzi is a professor of marine, earth and atmosheric sciences at NCSU.  He'll try to better predict Atlantic hurricanes by advancing computing techniques used to analyze climate data sets.

Samatova, an associate professor in computer science, will try to develop a new approach to Atlantic hurricane prediction.

At N.C. A & T in Greensboro, engineering professor Abdollah Homaifar, a data-mining expert, received $900,000 to develop new fusion an dsearch algorithms that will help scientists and public officials better predict hurricane activity.
 

John Bruno, an associate professor of marine ecology at UNC-Chapel Hill, is at the center of an international debate about the health of the oceans. His findings, published in last month's issue of the journal Science, has sparked news reports and adds to the growing level of alarm. Read more about the Tar Heel of the Week here.

Scientists conducting experiments at Duke Forest reveal how a warming climate affects even the smallest woodland creatures. Read more about it here.
