two things about "global warming scientists"
1.- over the last 120 years, we have increased 0.8° C. Can they tell me they have an measurement of global temperature in the last 1000 years with an accuracy of degrees per century? I have tried to find it out, but there's no comment on this. Note: see this
https://www.carbonbrief.org/explainer-how-do-scientists-measure-global-temperature
and check that different institute measure different global temparature, there's more than 10% of difference between some institutes, pic related.
How can we be sure that the geological data measures the same as what we measure today? Maybe some asshole put the thermometer next to a high way! (I 100% trust satellite data)
2.- As
https://www.skepticalscience.com/climate-models.htm
says
>models are tested against the past, against what we know happened. If a model can correctly predict trends from a starting point somewhere in the past, we could expect it to predict with reasonable certainty what might happen in the future.
But different models predict different outcomes for the next 30 years! Each one more catastrophic than the previous one. How reliable are models that know the result they should get?
