At an emission plateau = still burning fossil fuels at 35Gt CO2/year like today, "removing" 2.5Mt CO2 by 100mio new trees in plantations doesn't show on a graph. OTOH, plantations need nutrients and water = #afforestation is tricky wrt #drought and shrinking #biodiversity.

At ‼️zero‼️ CO2 emissions, we need to first remove 50% and eventually all Gt CO2 emitted since 1990 to get back to 1ºC warming.
Add 2-4Gt/a to counter #PermafrostThaw and 2Gt/a for CO2 from dry #wetlands
