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.

Monster hurricanes reached U.S. during prehistoric periods of ocean warming

Intense hurricanes, possibly more powerful than any storms New England has experienced in recorded history, frequently pounded the region during the first millennium, from the peak of the Roman Empire into the height of the Middle Ages, according to a new study. The findings could have implications for the intensity and frequency of hurricanes the U.S. could experience as ocean temperatures increase as a result of climate change, according to the study’s authors.

Study Supplies Insight into Behavior of African Monsoon

Think of the Sahara and you will conjure images of a vast desert landscape, with nothing but sand as far as the eye can see.  But for a period of about 10,000 years, the Sahara was characterized by lush, green vegetation and a network of lakes, rivers and deltas.

This “green Sahara” occurred between 14,800 and 5,500 years ago during what is known as the “African Humid Period.” Why and how it ended is the subject of scientific study that holds important information for predicting the region’s response to future climate change.

In a study published this week in Nature Geoscience, a team of researchers provides new insight into the behavior of the African monsoon at the end of the African Humid Period and the factors that caused it to collapse.
