Warming triggers cooling?
To connect thoughts.
The unexplained warming period from AD 800 to 1300 is when Greenland was named because it was covered in plant life when the Vikings found it. The Vikings grew vineyards there and they saw no glaciers. Crops thrived in the rich soil and the growing season lasted 10 months with mild winters.
During this same period scorching temperatures, droughts and famine ravenged civilizations in Europe, Asia, North and South America.
Most of the worlds glaciers everyone is worried about melting did not exist during the Midieval Warming Period just 700 years ago.
Some scientists believe that the massive population die offs during the Midieval Warming Period triggered the global cooling of the Little Ice Age that followed as farmland across the world reforested and massive amounts of CO2 were held by the trees.
But what triggered the warming back in AD 800 in the first place?
Even the global warming scientists do not know.
