@realcaseyrollins You can just say hi, you dont need to make up random questions you know ill answer just to talk to me :)
11.5K years, the last one anyway.
Global warming begain give or take around 1900, so we are talking abotu 200 years since thent he change is about 1 degree celsius.
The ice age lasted 11,500 years and represented a total change (compared to the temp at 1900) of a 5 degree celsius change.
So that means we are talking abou a 0.08 degree change per 100 years for the ice age. Compare that to the 0.5 degree change per 100 years we are seeing. That means the current change in temperature is 6.5x faster than what happened during the Ice age... more or less.
