Cant do that fast enough, and it takes too much land... its generally old large trees that sequester more carbon - maybe not cutting those down yields better bang for buck.

Were almost at +1.5C, at current plateau of peak global emissions that will increase at around 0.3C per decade, taking us to around +2C in 15 to 20 years..

+2C is not really compatible with large human population - food production, water supply, shelter, peak heatwaves, storms etc.

So we need a way to survive "peak heat" - only things to bring the heat down are removing CO2 at massive scale, or reflect more sunlight over the oceans by increasing cloud cover by solar radiation management geoengineering, such as releasing Sulphur particulates.

We know the latter works because we can measure the cooling effect that higher sulphur in shipping fuels had, before we made shipping fuels 'cleaner'.
