Frequent volcanic erup0ons likely cause of long-term ocean cooling
An interna)onal team of researchers found an 1800 year-long cooling trend in the surface layer of the Earth’s oceans, and that volcanic erup)ons were the likely cause of this cooling from 801 to 1800 AD. The coolest temperatures were during the LiDle Ice Age - that was before man-made global warming erased the trend in the 1800s.
