My issue is with all of the alarmists. If someone has to go to an extreme to get my attention, (IE Miami will be gone in a few years,) you're probably full of shit and you're doing nothing to help your cause. Thunberg's rise to fame is just another form of sensationalism to me. On the other hand I cringe just as badly when I hear non-believers of climate change. However I'm not constantly exposed to that as an overreaching sales pitch, the worst of which I probably hear from time to time from Trump. (IE recently denounced the emissions tech in new cars)
16 years ago in college it wasn't as bad as it is now but still bad. So I wrote a paper on climate change and I ultimately landed on a few main points that I still believe after all this time.
Humans are contributing to climate change.
Slowing down is possible but not reversal.
All of the money being spent on subsidizing green energy would better be spent on preparing for higher water levels and temperatures(seawalls, cooling, relocation).
In 100 years we will have figured out fusion. In the mean time build more nuclear.
The one thing I now believe that i didn't 16 years ago is that electric cars will become the dominate mode within the next 10 years. Not because people want to be green but because they simply out perform their gasoline counterparts. That's the same way all of this will pan out as long as capitalism does what is does. Eventually fossil fuels will simply be too expensive, the market will be what ultimately makes everyone more "green."
