On what basics, can scientists predict the effects of climate change?
Climate science seems to be as relevant as other types of science. It's just that it has been organized ridiculed after the formation of IPCC in the 80's. It has a lot of heritage from physics and there are a lot of signs of a climate emergency.





Your question is not fully clear. Some effects are impossible to predict in detail while other is not. Down a prediction of the global temperature and the concentration of atmospheric CO₂ made by ExxonMobile's researcher 1980.
