How fast was the global warming at the end of the Younger Dryas, which had nothing to do with CO2 emissions?

The global warming at the end of the Younger Dryas, which occurred around 11,500 years ago, is believed to have been relatively rapid. The warming was likely caused by a number of factors, including a resumption of the Atlantic Meridional Overturning Circulation (AMOC), which is a large ocean current system that carries warm water northward from the tropics and cold water southward from the poles. The resumption of the AMOC is thought to have caused an increase in the amount of warm water that flowed into the North Atlantic, which in turn warmed the region and caused a warming of the climate in Europe and North America.

The warming at the end of the Younger Dryas is believed to have been relatively rapid, with temperatures rising by as much as 5 to 10 degrees Celsius in some areas over a period of a few decades to a century. This warming caused a number of changes in the environment, including the return of plants and animals that were forced out by the cooling during the Younger Dryas, changes in the distribution of plant and animal species, and an increase in the amount of precipitation in many areas.

Overall, the warming at the end of the Younger Dryas is believed to have been a relatively rapid and dramatic change in the global climate, and it serves as an important example of how climate can change quickly and have significant impacts on the environment and human populations.

It is important to note that the warming rate during the end of the Younger Dryas is much faster than the current warming rate caused by human activities.
