Personally, I think it is irresponsible for anyone to say that "it's too late" to fight global warming!
And I would respectfully request everyone to NOT spread this "it's too late" speculation.
First, because no one knows for sure if it is too late or not.
Second, because such a belief reduces (or even destroys) hope and efforts to save all life on Earth!
Third, because it matters profoundly how much of life on Earth humanity can save from now on.
That is, it matters profoundly if 25% or 50% or 75% or 100% of all life on Earth is killed by global warming.
ALL life matters, and the more life that humanity can save, the better - and we have a moral duty to save the most life we can!
As long as some life on Earth is saved -- and as long as the Earth is saved somewhat and is still livable -- life will continue and rebuild.
But if ALL LIFE on Earth is killed -- and if the Earth is made entirely unlivable -- humanity will have committed the most appalling, despicable, criminal, tragic crime against this miraculous, most beautiful world!
It breaks my heart to even imagine all life on Earth being killed -- and the glorious Earth being made unlivable -- all because of human selfishness, greed, stupidity, laziness, and lack of courageous action!
ALSO (as I recall), scientists at Stanford University recently calculated that current technologies already exist to move the U.S. (and thus the world) 100% to non-fossil fuel sources of green energy by 2035 or 2050.
The U.S. could do this IF the govt. did the equivalent of its mobilization effort in World War Two. Saving all life on Earth is an even greater need and cause than defeating the German, Italian, and Japanese fascists was!
The biggest obstacle is that govt. leaders in almost every nation of the world are controlled by 1% oligarchs and fossil fuel corporations and militaries that depend on fossil fuels to fight wars, to move around, and to run their various machines and physical plants.
Only mass movements by the common people in numerous nations can force the 1% rulers and militaries to save all life on Earth.
Yeah, I know our chances are terrible -- but saving all life on Earth is worth the effort!
And impossible odds have been overcome by humans many times throughout history.
And what will happen to All Life and to our Mother Earth if we don't even try?!
So never say "it's too late." And "never say DIE"!!!
