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.”

Julie Brigham-Grette on PBS NOVA “Polar Extremes”

Julie Brigham-Grette recently appeared on the NOVA special Polar Extremes, which takes viewers on an epic adventure through time at the polar extremes of our planet. In the episode Professor Brigham-Grette described her research on past climates drawn from long sediment cores from Lake El’gygytgyn in NE Russia. The interval from 1:03:18 to 1:08:00 focuses on this research. The 2 hour special premiered February 5, 2020. See it here.
