There is a problem with the climate crisis that effects are locked-in before they are noticed. For example, we are basically at 1.5C above pre-industrial levels now but it is likely that 2.0C is already “locked-in” so that if we were to stop all emission of climate gases now, we would still reach 2.0C. This is a serious problem because it means that real, effective change to avoid climate disaster is likely to be to late. That raises the question is it worth the bother trying to prevent further climate disaster and the planet becoming uninhabitable: if it’s wasted effort shouldn’t we just enjoy our final years instead?

It’s then more of a question should we continue campaigning if we’re not being effective, achieving. I consider that we are achieving and the situation would be worse otherwise. It appears that we are achieving in UK despite Ed Miliband being so taken with the carbon capture false solution promoted by fossil fuels.
