You do know most of that ice melted relatively quickly? We don’t have much ice left to melt in comparison, and the levels haven’t changed much in the last 100

We don’t have much ice left to melt in comparison, and the levels haven’t changed much in the last 100 years really.
evidence doesn’t seem to support this thesis
- Hikikomori 3y agoDid temperature also change as quickly?
- lettergram 3y agoWe don’t know, we do know temperature increased (how quickly exactly no one knows)
- chrisco255 3y agoThe problem with inferring ancient temperature is you have to rely on sparse proximal data (ie tree rings, ice cores, etc) that is only accurate within 1 or 2 degrees C for estimation and then you have to fill in whatever's missing, geographically and temporally. Still sometimes the data does indicate sharp, dramatic changes, such as the Younger Dryas, about 12K years ago. After the recent glacial period ended, roughly 14K YA, there was a plunge back to glacial temps over a couple centuries which lasted about 1200 years, then very suddenly the temperature rose almost 20C. https://en.wikipedia.org/wiki/Younger_Dryas#/media/File:Younger_Dryas_and_Air_Temperature_Changes.jpg https://en.wikipedia.org/wiki/Younger_Dryas#/media/File:Youn...
- verisimi 3y agoI agree. The issue with doubting ancient temperatures, is that one has no faith in the predictions of science for the present, as this is the basis/metric in use.
