Earth core cooling
The benthic foraminifera extinction is illustrated by the red arrow. Weird structures near Earths core may be scars from a primordial interplanetary collision.

Scientists dont agree on when it started and ended but its generally agreed.
. Evidence for global warming at the Paleocene Eocene thermal maximum from a core located off the coast of Antarctica. Decreasing oxygen isotope values indicate the warming of the surface ocean planktonic foraminiferal isotope values and deep. Click for a text description of Evidence for Global Warming image.
By Brandon Specktor published 7 January 22. A collision with a Mars-size planet 45 billion years ago. Estimates of mantle primordial heat loss range between 7 and 15 TW which is calculated as the remainder of heat after removal of core heat flow and bulk-Earth radiogenic heat production from the observed surface heat flow.
The Little Ice Age is the name for a period of widespread cooling on Earth. The Earth cores heat flowheat leaving the core and flowing into the overlying mantleis thought to be due to primordial heat and is estimated at 515 TW.
