2. Background: Most scenarios have positive emissions (brown) & carbon dioxide removal (green) to get a net (black).
Because of hard-to-mitigate sectors, CDR is needed to:
1. Offset residual emissions
2. Bring temperatures down (optional)

3. (bonus extra). It is not necessary to have so much CDR that it causes temperature overshoot (light green in previous figure) because of net-negative emissions.
Here is a scenario which just goes to net-zero, & has enough CDR to stay there.
