[Terrapreta] Jim Hansen on our side

[Folke Günther]

In a recent letter (yesterday), Jim Hansen says:

There is tremendous potential for reducing atmospheric CO2 via reduction of

deforestation, improved forestry practices, and improved agricultural
practices that

increase carbon storage in the soil. If governments were to encourage such
practices,

rather than the converse, and if coal use were phased out except where the
CO2 is

captured, it would be possible to literally roll back the net human-made
climate forcing to

levels below those defining critical tipping points.

We must remember, at the same time, that the ability of the principal CO2
sink, the ocean,

to soak up human-made emissions is limited and slow (Figure 1). If we burn
most of the

available coal (Figure 3) without CO2 capture, even with the lowest
estimates of available

coal reserves, it will be impractical if not impossible to avoid passing
climate tipping

points with disastrous consequences.
