Data: A reconstruction of global hydroclimate and dynamical variables over the Common Era

The Paleo Hydrodynamics Data Assimilation product (PHYDA) is the first global reconstruction of hydroclimate and associated dynamical variables.  It uses a novel data assimilation method and the largest multiproxy database assembled to date by combining several community-complied proxy datasets.  The reconstructions, code, and proxy data were all made public upon publication and are available through the NOAA NCEI data pages and through th

‘Megadrought’ and ‘Aridification’ — Understanding the New Language of a Warming World

After nearly two decades of declining water flows into the Colorado River Basin, scientists have decided the word drought doesn’t cut it anymore. We need different terms, they say, to help people fully grasp what has happened and the long-term implications of climate change — not just in the Southwest, but across the country.

The term that’s caught the most attention lately is “megadrought.”  Read More

Climate-Driven Megadrought Is Emerging in Western U.S., Says Study

With the western United States and northern Mexico suffering an ever-lengthening string of dry years starting in 2000, scientists have been warning for some time that climate change may be pushing the region toward an extreme long-term drought worse than any in recorded history. A new study says the time has arrived: a megadrought as bad or worse than anything even from known prehistory is very likely in progress, and warming climate is playing a key role.
