Cause of hiatus found deep in the Atlantic Ocean

by Judith Curry

Rapid warming in the last three decades of the 20th century, they found, was roughly half due to global warming and half to the natural Atlantic Ocean cycle that kept more heat near the surface. When observations show the ocean cycle flipped, the current began to draw heat deeper into the ocean, working to counteract human-driven warming. – Chen and Tung

Explaining(?) abrupt climate change

by Judith Curry

 . . . suggesting that Dansgaard-Oeschger events resulted from a combination of the effects of sea ice and ice shelves—structures that help define the margins of ice sheets—to account for both the rapid and the slower parts of the cycle.
