For the past two decades, the southwestern United States has been desiccated by one of the most severe long-term droughts—or ‘megadroughts’—of the last 1,200 years. And now, scientists say the risk of similar extreme megadroughts and severe single-year droughts will increase in the future as Earth’s temperature continues to rise, according to a new study in Earth’s Future.

Results show the increasing frequency of these compound extremes is strongly driven by human-caused warming and drying trends.

The study provides insights that could potentially extend the warning lead time of cold extremes in the United States, Canada, and Asia.

Tropical cyclones are one of the most intense storm systems on earth and nearly one-third of global tropical cyclones form in the western North Pacific. So why was the 2020 season quiet? A new MAPP-funded study helps answer this question.

The new white paper describing the research challenge identifies opportunities for increased understanding of U.S. coasts in the face of extreme weather and climate change.
