To be fair, the public in large also dgaf about climate change.
Honestly, at this point, having natural disasters with destruction and death is probably the only way to make people care.

We already have them. People just claim they're chance effects with no connection to climate change.
The problem with refuting it is that they are chance events, there's no way to definitively say "this was caused by climate change", because it's always possible it would have happened anyways. It's the upwards trend in frequency and severity that we can definitively point and say "that's caused by climate change", but that's too abstract for most people to understand.
Well, it is an El Nino year...
This is not true, most people care about climate change, even in the US (https://climatecommunication.yale.edu/visualizations-data/yc...). Maybe you think "if they care then why are they still driving/flying/eating meat/whatever" and I sympathize, but climate change is not an issue that will be solved by individuals taking responsibility, in the same way that wars still happen even when the vast majority of the population oppose them.
If you're wondering why they don't at least vote for someone who cares about climate change, I don't know. But claiming people don't care at all is not true and is self-defeating, because it makes people who do care think "I guess I'm in the minority, there's no point in trying".
