// ... the climate has always changed, nothing, new natural cycles. //
Sigh... as usual, you are accepting a conclusion that was only reached because Climate Scientists investigated this, and yet ignoring the same scientists when it comes to the more inconvenient message: human activity is having a measurable impact right now, and will continue to have a measurable impact, above and on top of what natural cycles provide.
I'm not saying I agree with this woman in terms of the speed and scale of societal collapse either, mind -- but it's possible to suggest that she's overreacting at the same time as recognising that the concerns are far more legitimate than you are giving them credit for. The way we generate energy and electricity, the fuel we use for travel, the standards we set for new buildings, how and where we source our food -- all these will have to change. If it's done in a sensible and managed way then there's no reason to fear total societal breakdown.
