New research on Arctic Rivers

In a pair of new papers, Michael Rawlins and colleagues describe new numerical model simulations of dissolved organic carbon (DOC) loaded to rivers throughout the western Arctic and how flows of water and DOC are increasing in northwest Alaska.

Raymond Bradley awarded $2.5 million grant to study climate and environmental history of Greenland’s northernmost region

CSRC Director Raymond Bradley will lead a team of researchers to Peary Land, Greenland’s northernmost region to document past changes in the climate and environment of the area. This project is supported by a $2.5 million grant from the National Science Foundation. Read more here.

Ph.D. candidate Ruthie Halberstadt awarded an NSF Post Doctoral Research Fellowship

Ph.D. candidate Ruthie Halberstadt has been awarded a highly competitive NSF Post Doctoral Research Fellowship: “High-resolution Nested Antarctic Ice Sheet Modeling to Reconcile Marine and Terrestrial Geologic Data”. Her research project includes ongoing collaborations with professors Rob DeConto, her advisor, and Greg Balco at UC Berkeley.

New Modeling Study Points to Antarctic Ice Sheet Contributing to Rapid Sea Level Rise

In a new paper, published today in Nature, Rob DeConto and colleagues describe how warming in excess of 2 C would drastically accelerate the pace of sea-level rise by 2100. The team used a physics-based model of the ice sheet to test Paris Agreement target temperature thresholds. Read more in the UMass news release and the open access journal paper.

Research reveals more than a third of U.S. Corn Belt farmland has lost a carbon-rich topsoil

Research conducted by UMass Amherst Geosciences graduate student Evan Thaler, along with professors Isaac Larsen and Qian Yu, developed a method using satellite imagery to map areas in agricultural fields in the Corn Belt of the Midwestern U.S. that have no remaining A-horizon soil. Read the UMass news release and see the journal article for more information.

New National Science Foundation project to drill through the Greenland Ice Sheet

Rob DeConto and teams from Columbia, Penn State and the University at Buffalo will receive $3 million in research funds and $4 million for field operations to drill through the Greenland Ice Sheet and into the bedrock below, where they will be able to evaluate how long it has been since the last ice sheet retreated from the continent.

NOAA Report on U.S. High Tide Flooding

The National Oceanic and Atmospheric Administration has released a report on coastal flooding in the U.S. caused by rising seas due to the warming climate. The CSRC’s Rob DeConto commented in an article in the Boston Globe on high tide flooding and the report. “This problem isn’t going away …. the combination of ongoing sea-level rise and increasing tidal range in the 2030s will conspire to really increase the number of these nuisance flood events.”
