Climate Interface of Younger Dryas Event, Deforestational Agriculture and the Milankovitch Cycle

If you study the charts of Earth’s temperature records and the Milankovitch Cycles, you’ll see as the planet comes out of an ice age, the increase in global temperature is rapid, steady and peaks at the start of the interglacial period. The global temperatures then slightly start to ‘gently decline’ before finally taking a haphazard ‘rapid decline’ to the coldest part of the next ice age before again repeating the temperature increase of the next Milankovitch Cycle. That’s the norm. However, the level of our current interglacial’s peak was hampered by the Younger Dryas Event that occurred about 13,000 years ago. Four thousand years later following this, mankind began deforesting the planet, overgrazing livestock, practicing slash-and-burn farming, etcetera — all of which disrupted the carbon cycle by increasing the level of carbon dioxide in the atmosphere, which prevented global temperatures from decreasing. As such, temperatures would’ve remained stable, too, if vast amounts of sequestered carbon had not been recently released thru the burning of fossil fuels.

NOTE: This is the single best short video on understanding climate change I’ve ever seen. Indeed, once I’ve posted this, anything else that I post subsequently on the subject of climate change will seem incidental.

If you supplement it with the YouTube channel “Just Have A Think”, then you’ll be set:
