Here's the problem.
Since the ice age disaster predicted in the 1970's, the acid rain disaster predicted in the 1980's, and the ozone hole disaster predicted in the 1990's, there might not be enough vital strength left in our species to fight the global warming disaster predicted in the 2000's.
According to economic models forecasting the horrible effects of unchecked global warming, we are going to have to put up with this dire situation: 80 years from now, global GDP will be 10% lower than it would be without global warming. That means in 2100, the world would have only 10x as much wealth as today instead of 11x as much wealth as today. Grim indeed.
On the positive side, maybe it is possible that global warming eliminates the next ice age. An ice age would cause global GDP to be 0x today's GDP and would wipe out 90+% of humans (and of most other species). So, there is that consolation, maybe.
Of course, there are also some higher-probability things with regard to humans and the planet: wars, nations so egregiously mishandling themselves that it causes mass misery and death of their own citizens, epidemics, Carrington events, supervolcanos, asteroid strikes, need for water, energy, food, dealing with waste, etc. -- things that we can clearly see the risk of without speculative models that have a thousand adjustable parameters (and thus are nearly certain to be useless for prediction).
Then there is the issue of us entering the age of media having drastically more-powerful tools to influence the populace. We are living through -- right now -- the transition of big media upgrading to nuclear weapons of propaganda instead of the old conventional weapons of propaganda. It is becoming a dangerous time where media is full of so many lies, fakes, factions, agendas, and attempts to manipulate that people should not believe most of what they see. Eisenhower warned of the military/industrial complex. We are in the time of the media/government-faction complex.
Global warming is not my greatest concern.
