Ice Ages & Past Climates
Secrets in the 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.
Read MoreIcebergs 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.
Read MoreStudy Finds 6⁰C Cooling on Land during the Last Ice Age, With Implications about Future Global Warming
A recent report shows that prior studies have underestimated the cooling in the last glacial period, which has low-balled estimates of the Earth’s climate sensitivity to greenhouse gases. The rather high climate sensitivity is not good news regarding future global warming, which may be stronger than expected using previous best estimates.

Study reveals Missoula Floods impact on past abrupt climate changes
A new study shows for the first time how massive flood events in the eastern North Pacific Ocean—known as the Missoula Floods—may have in part triggered abrupt climate changes in the Northern Hemisphere during the last deglaciation (approximately 19,000–11,700 years ago).
Read MoreWhy 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.

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.

Read MoreThe 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.
