A new study revealed that effusive volcanisms in Mercury most likely stopped about 3.5 billion years ago.
A global cooling event during the Jurassic Period was triggered by a volcanic event that altered the flow of warm waters from the equator to the North Pole Region. This caused very cold temperatures in the northern hemisphere for many millions of years.
An 1,800-year-long trend driven by volcanic activity was brought to an end by 19th-century, human-caused global warming. Recent studies of this phenomenon question the exact role that oceans play in climate change.
