UMass study: Coastal Northeast is warming faster than most other regions in the U.S.
In a paper recently published in Nature Climate Change, Ambarish Karmalkar, research assistant professor and investigator with UMass-Amherst’s Northeast Climate and Adaptation Science Center, described the accelerated warming and factors behind the trend. Read more in the UMass news release.
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.
CSRC’s Julie Brigham-Grette playing a prominent role in international effort to limit GHG emissions
University of Massachusetts Amherst professor of geosciences Julie Brigham-Grette is playing a prominent role in a new international effort, named www.50×30.net, to reduce greenhouse gas emissions. UMass-Amherst is a founding institution. Read more in the UMass press release.
Research study investigates history of the Antarctic ice sheet
In a new study published in the journal Earth and Planetary Science Letters, CSRC Ph.D candidate Anna Ruth Halberstadt and an international team used numerical models and geologic datasets to reconstruct Antarctic climate during the the mid-Miocene. Read more in the UMass press release and journal article.
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.
Study using lake sediments reveals Atlantic sea-surface temperatures are warming
A study published today in the Proceedings of the National Academy of Sciences by Francois Lapointe, Raymond Bradley and colleagues documents how Atlantic sea-surface temperatures in the recent decade are warmest as compared to their estimates spanning the past 3,000 years.
