IPCC Science Fast Facts
1. Emissions from humans have warmed the atmosphere
2. The changes are unprecedented
3. The current extreme events can be linked to climate change
4. Changes in extremes get more frequent and intense as emissions rise and more widespread and more pronounced.
5. Many changes are not likely to be reversed for centuries to millennia
6. Warming levels will go over 1.5 and 2 degrees unless there are immediate, rapid and large-scale emissions reductions
7. Plus some carbon dioxide removal
8. Positives: we have the ability and the tools to change
9. Under all projected scenarios, carbon dioxide emissions go down to at least net zero. It just depends how hard and fast it happens
