Flutterbee, I think things need to be done, and urgently. We need to start building reactors now, not tomorrow, not when a consensus is formed by victims of our defective education system, but now.
As for carbon neutratlity, I think it's an amusing and mostly harmless affectation or marketing technique, not a method for addressing these issues.
Trees only buffer CO2, do nothing about CH4 and actually make the effect from water vapour marginally worse. When a tree dies, it's carbon goes directly back into the system, in a rain forest that's quite rapid, this is part of the issue that they typically have thin soils.
Also I'm sad that GeorginA doesn't get the nature of climate models, and as such is in the BBC led majority.
But it is genuinely big problem with the way almost all people think about low probability/high consequence events, they thinkof them as "SciFi" and simply exclude them from their thinking.
A bit of reading on geology will show that that some very large events have ocurred in the Earth's history, many of which make the most lurid preduciton of sharks swimming through the streets as London as reasonable as "maybe it will rain in September".
Of the deeply bad shit, the probability of any given scenario is quite low. But the probability consequences is scarliy high. Try to think of it as hittin g a golf ball. The chances of you hitting any blade of grass is almost zero, but the chances of hitting some blade of grass is high (even if you're as crap at golf as me, and likely to hit trees, other players or sand).
