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.
CPO-funded scientist Dr. Isla Simpson recently received The Clarence Leroy Meisinger Award from the American Meteorological Society (AMS).
The sobering report finds that climate change is already affecting nearly every part of the planet with rapidly intensifying impacts, and human activities are unequivocally the cause.
The Climate Program Office (CPO) manages competitive research programs in which NOAA funds high-priority climate science, assessments, decision support research, outreach, education, and capacity-building activities designed to advance our understanding of Earth’s climate system, and to foster the application of this knowledge in risk management and adaptation efforts. CPO-supported research is conducted in regions across the United States, at national and international scales, and globally. Learn more...
Americans’ health, security and economic wellbeing are tied to climate and weather. Every day, we see communities grappling with environmental challenges due to unusual or extreme events related to climate and weather.
