Thirty-nine years of satellite data reveal that the prevalence of intense hurricanes, cyclones, and typhoons—category 3 and above on the Saffir-Simpson scale—is increasing.
A new investigation into the sensitivity of extreme precipitation in a changing climate indicates that more winter rainfall and protracted snowmelt may require local adaptations to winter flooding impacts.
Government-sponsored research and regulations enabled western U.S. states to clean up their air, despite industrial and population growth. Proposed funding cuts could undo this progress.
By greatly reducing the associated uncertainty, a new model is better able to discern statistically significant trends, offering the potential to improve the seasonal forecasting of rare events.
Large-scale climate change may drive trends in extreme sea level events.
Basing forecasts on data that preserve variations over space yield more reliable predictions than using standard numerical measures of climatic cycles' intensity.
