This came up last week, but has 'disappeared', as best as I can tell.
The Younger-Dryas is another phenomena which also experienced a mis-attribution within the scientific community:
1) This Heinrich event ('cold-reversal'), which occurred 11,600-years ago in the Atlantic Ocean, was originally thought to have originated from a massive freshwater pulse entering the ocean, from an ice-dam breach, from 'Lake Agassiz', which had formed over North America, from the melting of the Laurentide Ice Sheet, at the end of the last ice-age.
2) The hypothesis was that, the freshwater diluted the thermohaline heat conveyor of the Atlantic Meridional Overturning Current ( AMOC ) [ the 'Gulf Stream' ] from the Equator so much that it failed to deliver heat to the North, bringing on the 2,000-year cooling event ( The Day After Tomorrow ).
3) Again, high-altitude, mountain glacier ice-cores would reveal that the phenomena was actually driven by 'atmospheric' drivers, specifically, a draw down of atmospheric methane ( CH4 ). This IS the reason for alarm, as the melting of Arctic permafrost will play the Heinrich event in reverse, causing a rapid buildup of methane, which is 87-times more powerful as a greenhouse gas than carbon-dioxide. When the methane eventually biodegrades, it will become carbon dioxide, for a thousand years. Rapid warming!

In 1900, Earth averaged 56.58-F
2006, 57.99-F
2024, 59.00-F, Delta 2.5-F ( delta- 1.344-C )
An additional 0.656-F will take us to 2.00-C.
Turning coal-fired power plants will take us to 60.5-F ( delta-2.51-C )
The Moon's average temperature hasn't changed over the past 124-years.
