Secrets in the dust

Sea Dust

Researchers investigate dust from the ocean’s farthest point from land to reconstruct the climactic history of the Southern Hemisphere, and understand how micronutrients have influenced biological productivity in this oceanic desert.

Icebergs drifting from Canada to Southern Florida

A newly developed iceberg computer model helped the researchers understand the timing and circulation of meltwater and icebergs through the global oceans during glacial periods, which is crucial for deciphering how past changes in high-latitude freshwater forcing influenced shifts in climate.

Why is the Greenland Ice Sheet melting faster than ever?

Senior scientist Claudia Cenedese has been studying how glaciers melt for the last 15 years in her fluids laboratory. In 2018 she was a principal investigator on a research cruise in Greenland for the first time. She wants to understand why the Greenland Ice Sheet is melting faster than ever and what happens to the fresh water released into the ocean.

More Than 11,000 International Scientists Declare Climate Emergency

WCAI

A new paper endorsed by 11,258 scientists and researchers from 153 countries describes climate change as a “climate emergency.” Published in the journal BioScience, it warns of “untold human suffering” if individuals, governments, and businesses don’t make deep and lasting changes.

Paleoclimatology

Earth’s climate has undergone many changes over the course of geologic history, but the past one million years or so…

The long memory of the Pacific Ocean

The long memory of the Pacific Ocean

Researchers from the Woods Hole Oceanographic Institution (WHOI) and Harvard University have found that the deep Pacific Ocean lags a few centuries behind in terms of temperature and is still adjusting to the entry into the Little Ice Age. Whereas most of the ocean is responding to modern warming, the deep Pacific may be cooling.
