CNN is correct. Realizing such technology can make countries like the reluctant USA lazy about climate.
Earth's climate crisis is real. It is effecting the troposphere, but, also the stratosphere and COLLECTIVELY every country on Earth MUST apply strong moral principles to their national policies or we are looking at a homogenized atmosphere that no longer supports life.
The thing about Earth is that it is real reluctant itself to change. It likes to remain stable and an ice planet, but, what is also true about Earth is that once it reaches a tipping point, it is all over and the physics of this planet change permanently until all the effects that brought on the tipping point disappear.
You see, Earth is reluctant to change BACK to it's benevolent form even after the tipping point. Or, better said, once the tipping point occurs Earth's physics will favor stability no matter the harm being caused to the support of life. Earth is a planet and not a process of daily living and certainly not a mass of financial capital that can be maneuvered and manipulated. There is no bear or bull market that can guarantee Earth's cooperation in maintaining life.
Earth has a balance and if that balance is seriously disturbed by changes in it's atmospheres, the show is over.
CNN is correct in recognizing something politicians can lob onto and state they are just as Green as any other Greenie on the planet. That would be tragic politics. Earth requries life to maintain life. It requires forests and grasslands and all sorts of diverse life adding and removing chemical content of it's atmospheres. Earth exists to support life until that life turns Earth on it's head.
