In Oman, geochemist Peter Kelemen is investigating rocks thrust up from the deep earth, which naturally take up and store atmospheric carbon dioxide.
Scientists from Lamont-Doherty Earth Observatory with IcePod, an instrument that collects data about the changes occurring in ice sheets and glaciers.
Lamont-Doherty Earth Observatory oceanographer Joaquim Goes recovers floating sediment traps during a research cruise in Antarctica’s Ross Sea.
Marine ecologist Andy Juhl takes the temperature of a fresh core of sea ice during fieldwork near Barrow, Alaska.
Biogeochemist Sonya Dyhrman captured this shot of the R/V Nathaniel B. Palmer as it steamed along the coast of the Western Antarctic Peninsula.
Geologist Sidney Hemming and a colleague examine glacial debris along the edge of Antarctica’s Foundation Ice Stream.
Oceanographer Bärbel Hönisch collects free-floating planktic foraminifer—single-celled marine organisms with calcite shells—off the coast of Puerto Rico.
Billy D’Andrea seeks to understand global climate change by reconstructing climate history using molecules preserved in lake sediment cores.
An inter-disciplinary team of scientists is evaluating the impact of the Rhone Glacier’s retreat on nuclear and hydropower in the region.
Scientists are leveraging big data science, computational biology, and genomics to study the behavior and changes in phytoplankton.
Richard Seager combines paleoclimate and modern records with climate model simulations to determine how the combined effects of natural variability and climate change will affect droughts and floods around the globe.
The development of continental-scale drought atlases from tree-ring records has fundamentally altered our understanding of how variable and long lasting periods of drought have been in the past and could be in the future.
One way to get to negative CO2 emissions is to capture CO2 from the ambient air. Peter Eisenberger and colleagues are developing ways to mimic nature by using CO2 to make synthetic liquid fuels that are carbon neutral.
To understand how the ice sheets will respond to global warming and how sea level could rise, we need to know what happened to sea level the last time CO2 levels were this high.
