Now, thanks to a photographer’s keen eye, and data from ESA’s Swarm satellites, we may have found it. Steve was a sensation when scientists stumbled across it a few … Read more
Arctic sea ice is shrinking as the world continues to warm, and a new study led by researchers at Penn State may provide a better understanding of how the loss of this ice may impact daily weather in the middle latitudes, including the United States. The researchers used climate models and a machine learning approach … Read more
Scientists at the University of Massachusetts Amherst recently combined satellite data, field observations, and sophisticated numerical modeling to paint a picture of how 22.45 million square kilometers of the Arctic will change over the next 80 years. As expected, the overall region will be warmer and wetter, but the details—up to 25% more runoff, 30% … Read more
