Conversations about sea-level rise often spotlight warming temperatures. But Earth’s geological engine quietly plays its own role. Professor Colleen Dalton, together with colleagues, connects the dramatic change in sea levels to a slowdown in seafloor spreading that reshaped the depth of the ocean basins.

Every year, distinguished Brown scholars are nominated for Research Achievement Awards by their colleagues for conducting exceptional and transformative research. Assistant Professor Daniel E. Ibarra was named one of the The 2025 Early Career Research Achievement Award winners for his significant contributions to geochemistry, paleoclimate studies, natural resources, and the training of aspiring scientists.

In a new Science Advances publication, Assistant Professor James Dottin III demonstrates how Hydrogen may leak from the core into the lowermost mantle, become entrained in mantle plumes, and mix into the upper mantle. "We typically think about the water cycle on the surface," explained Dottin, "but we often don't consider what happens to water beneath our feet through deep Earth processes." By measuring 2H/1H ratios in olivine-hosted basaltic melt inclusions from a Baffin Island lava, Dottin and his team investigated whether mantle plumes contain Hydrogen from the core. "This means that some the the water you're drinking today might be seeing the surface for the first time since the Earth was formed."

Swathes of scientific data deletions are sweeping across US government websites, and scientists are racing to save their work before it's lost. "Climate science is only possible because of long-term datasets," says DEEPS Postdoc Lilian Dove, a US Noaa climate and global change research fellow. "Without continuing to collect that data, preserve that data, our field is in really big trouble."

Dr. Bethany Ehlmann, a 2010 graduate of Brown with with a PhD and MS in geology, has been named director of the Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado Boulder.

As President Donald Trump’s administration looks to reverse a cornerstone finding that climate change endangers human health and welfare, scientists say they just need to look around because it’s obvious how bad global warming is and how it’s getting worse. “There is no possible world in which greenhouse gases are not a threat to public health,” said IBES Director and DEEPS Professor Kim Cobb. “It’s simple physics coming up against simple physiology and biology, and the limits of our existing infrastructure to protect us against worsening climate-fueled extremes.”

A new study by DEEPS Professors Colleen Dalton, Chris Huber, Tim Herbert, and Senior Research Associate Weimin Si explores how variations in global mean sea level over millions of years originate from changes in both the climate and solid Earth systems.

Since US President Donald Trump stated his ambition to acquire Greenland by sale or by force, the upcoming election in Greenland and political discourse among the almost 60,000 Inuit inhabitants has acquired a new level of intensity. In a new article in the Journal of the North Atlantic & Arctic, authors Dr. Charles H. Norchi from the University of Maine School of Law and Dr. Amanda H. Lynch from Brown University cast light on the past, present, and future issues of international interest that Greenlanders face in the upcoming elections.
