Furthermore, it’s generally untrue that any particular warm October is due to climate change but rather the average October temperature over many years.
We should avoid the association between climate and short term weather phenomenon altogether.

Even if people can't leave their house (except for some limited purposes) the reduction in carbon emissions are relatively small. It's a problem for government and industry to solve in the main. The only difficulty is how to ensure that we elect governments who take it seriously without scaring some people?

You can say something like over the last decade droughts are 32% more frequently than in the previous decade but just tacking it arbitrarily on to any reporting about a particular weather event is misleading.
