Yes, there were extreme events in the past. These events are now much more frequent thanks to climate change. Sometimes 10s to 100s of times more common.

Gloal climate change is caused by human emissions of greenhouse gases. This is now very clear and there is very little evidence of anything else having more than a small impact.

The COVID lockdowns had an effect on the climate, see for example the reduction in high clouds due to a decrease in flying [0]. Stopping GHG emissions only prevents further climate change. It does not fix it, just stops it from getting worse.

To change the climate 'back', we have to remove CO2 from the atmosphere, not just stop emitting it.

Many people who want to stop climate change are also pro nuclear energy as a means of doing that. But why would that have anything to do with redistribution of the means of production?
