publishes UMaine release on study of expanding spatial extent of heat waves – B. Lyon published a University of Maine news release about a new study that found the average spatial extent of summer heat waves in the United States could be up to 80% larger than today if greenhouse gas emissions continue unabated. The study was led by Bradfield Lyon, associate research professor with the UMaine Climate Change Institute and School of Earth and Climate Sciences. The study provides a new framework from which to analyze heat waves and their impacts, and was funded in part by the NOAA Climate Program Office’s Climate Observations and Monitoring Program, according to the release.
