It is scarey.
But I can't help thinking that, alongside doing what we can as individuals to reduce emissions etc., there are other things that can be done, even though they won't cure the problem.
Flooding can be reduced (not cured) by not building on flood plains and by good river management. These won't stop the rain, of course.
The threat from wildfires can be reduced by having proper firebreaks and getting rid of dry undergrowth. Such measures can stop the fires spreading so fast.
We're not going to be able to put things right quickly, if at all, but we can try to make them better. It's always easier to dig yourself into a hole than to get out again, so anything we do has to be joined-up (lots of different measures) and long term.
