The IPCC report proves that futureconsequencesdepend greatly on how quickly we manage to reduce carbon emissions and to what extent we can prevent warming in the future. Any warming has significant effects, but there is a significant difference between keeping it at 1.5°C and 2°C or above 3°C, which is the current trajectory of global warming.
2°C is no longer an acceptable limit, according to the report, because the IPCC estimates that its consequences are far more dangerous than previously predicted and would mean widespread devastation of our civilization.
Warming below 1.5°C means less exposure to severe heat waves, rainstorms, storms and floods, as well as saving most of the world's plant and animal species from the effects of climate change.
