“At the Leaders Climate Summit, countries will present their new climate commitments, like net-zero emissions by 2050. They will call these hypothetical targets ‘ambitious’. But when you compare their insufficient targets with the overall current best available science, you clearly see that there’s a gap. There are decades missing.”
What are the missing decades? The science Thunberg is referring to is the conclusion that we must reduce global emissions to zero by 2030, to avoid catastrophic consequences.
To reach that target, we should have already begun to cut back carbon emissions, but instead the world continues to move in the opposite direction.
