@Boris_yo would you believe ? because the scientists are to busy making money on it already.
The politicians have to wait for the bribes
If they roll over to early, there goes the pot o' gold.
You realize that they will "fix" global climate change, just like they fixed everything else. We just need to give them money, for some really smart sounding solution, that will go horribly wrong and then we really got something to worry about.
As odd as it sounds, there was going to be global cooling, the billions of tons a year of particles in the air (much like a volcano or massive forest fire) were going to block the sun. we would all freeze to death and die. (in our cars with the motor running)
They "fixed" the particulate problem, by arranging to have ONE aspect of the horrific world damaging pollution slowed down drastically , this (of course) takes it further off of nature, as an imbalance. The gasses are going into the air still , pretty much making every person breathing them rather "different" and the particulates no longer provide any balance.
Sooo, dumasses that they are, they are researching (none other than) purposefully putting way more horrific particulates into the air, to "solve" the problem. It makes perfect sense
Then, knowing human nature, they will want to distribute this mylar garbage (guessing) into low earth orbit, so it will stay in place longer. This of course will be very easy to control, because it will be spread out 165 million miles.
And getting up there to "fix" it again is not so easy.
Next they will have to release "Smart Particles" they will be designed to attract and disemnate the first set of particles. By doing so they will add another 58trillion tons of rocket fuel based gasses into the air, making the other problem worse.
The "smart particles" will be designed to attract, with unintended consequences, they will attach themselves to sattalites booster rockets, the moon, and space junk will be raining down out of the sky.
But that isn't a problem yet, because they will "FIX" that . . . .
Almost the first lesson in science , the last lesson in business "cause and effect" for every action there is an equal and often way worse :-) reaction.
