In almost every region of the world where hurricanes form, their maximum sustained winds are getting stronger. That is according to a new study by scientists at the National Oceanic and Atmospheric Administration National Center for Environmental Information and University of WisconsinMadison Cooperative Institute for Meteorological Satellite Studies, who analyzed nearly 40 years of hurricane satellite imagery.

Last year was one of the worst years on record for the Greenland ice sheet, which shrunk by hundreds of billions of tons. According to a study published today in The Cryosphere, that mind-boggling ice loss wasn't caused by warm temperatures alone; the new study identifies exceptional atmospheric circulation patterns that contributed in a major way to the ice sheet's rapid loss of mass.

The National Science Foundation (NSF) recently awarded $8.2 million to the Woods Hole Oceanographic Institution (WHOI) to extend the life of the Overturning in the Sub-polar North Atlantic Program (OSNAP) in a key part of Earth’s ocean-climate system. The award is part of a $15.5 million grant to four U.S. institutions that will help add four years to the record being assembled by the observatory.

In testing solar panels, the sun’s intensity, the spectral composition and the angle of light are important factors in understanding why certain panels are successful and others degrade more quickly. To address the knowledge gap in degradation mechanisms for various photovoltaic types, researchers performed tests over five years in which they collected weather data and panel performance information. The results are published in the Journal of Renewable and Sustainable Energy.
