Science predicts 2°C if world acted at least ten years ago.
> Current climate policies: projected warming of 2.8 to 3.2°C by 2100 based on current implemented climate policies;
> No climate policies: projected future emissions if no climate policies were implemented; this would result in an estimated 4.1 to 4.8°C warming by 2100

- adrianN 6y agoAnd climate models generally don't yet take into account tipping points, so they are most likely conservative in their estimates.
- manfredo 6y agoRight, and ~3 degrees of warming if we continue with current energy policies for the next 80 years is much more benign than what many are claiming. It's not uncommon for people to claim that carbon emissions need to be reduced to zero in the next twelve years or the earth will become uninhabitable. If that were true then yes, we should start bombing fossil fuel plants. But in reality the damage causes by such action would be far more damaging than climate change.
- sergeykish 6y agoThat's actually a lot, it is 3 times weirder that today. Countries claim carbon emissions have to be reduced to zero [1]. I do not think Eco terrorism would work. [1] https://en.wikipedia.org/wiki/Carbon_neutrality https://en.wikipedia.org/wiki/Carbon_neutrality
