Long-term Data Show Hurricanes are Getting Stronger
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 analysed nearly 40 years of hurricane satellite imagery. ‘Through modelling and our understanding of atmospheric physics, the study agrees with what we would expect to see in a warming climate like ours,’ says James Kossin, a NOAA scientist based at UW-Madison and lead author of the paper, which was published recently in the Proceedings of the National Academy of Sciences.

Scientists have created the first ever large-scale map of microscopic algae as they bloomed across the surface of snow along the Antarctic Peninsula coast. Results indicate that this ‘green snow’ is likely to spread as global temperatures increase.The team, involving researchers from the University of Cambridge and the British Antarctic Survey, combined satellite data with on-the-ground observations over two summers in Antarctica to detect and measure the green snow algae. Although each individual alga is microscopic in size, when they grow en masse they turn the snow bright green and can be seen from space. The study was published recently in the journal Nature Communications.
