You are correct, the question “what to do” is mostly political and social. As soon as we stop observing just what the US interest groups and politicians promote, we can see that the most of the world actually agrees that some steps have to be taken to reduce the CO2 emissions in order to attempt to limit the warming to “only” 2 degrees C:
The Paris Agreement ( French: Accord de Paris) is an agreement within the United Nations Framework Convention on…en.wikipedia.org
And if you follow the US politics, you know that there’s now “climate against” that agreement.
What can you do personally? Try to explain to the people you know what is really going on, but carefully: you obviously understand that it’s not something that’s easy to accept. There are some that simply don’t want. But I believe most people don’t want to make the future worse. I’ve personally been skeptical before I’ve done more research. The calculations that consider CO2 increase really match the estimates. And there can be other changes on the Earth, even some that we can’t predict good enough.
It’s about the responsible management of risks.
Use all the political influence you can use.
And, by the way, the “models” that estimate the future aren’t the weather models — they of course can’t predict when the next volcano erupts or the next El Niño happens, they just can say “in the given span of years, if the humans do this or that, the average effects can be expected to be this big.”
The average effects, if nothing is done, will have sure consequences to our children and grandchildren, even if they most probably won’t have to us personally. Note that averages are only averages, we’ll live day to day, there will surely be local extremes, “bigger than in recorded history” and “unprecedented” always more often. And there will be also the periods of “no change.” But then the new “records” will happen.
The whole topic is indeed complex, and very easy to be misunderstood.

The first step is accepting the responsibility for the problem, making people understand it. It is a problem, and it’s worth doing our best to minimize the risks and the impacts.
