Let's talk worst case scenario: Global warming=universal destruction
Scientist have come to the conclusion that yes, global warming is real and, yes, we need to act. However, science, being conservative, sends much of its predictions into the far future and limits scenarios to forseeable problems such as; three degrees of warming in a hundred years, a few feet of sea level rise in fifty, bigger storms, crop damage, population displacement, glacier retreat, etcetera.
Nobody wants to discuss the possible scenario that it is too late to prevent the complete elimination of life on earth...
The atmosphere of terrestrial planets is rich in heavy gases and gaseous combinations, CO2, Oxygen, Nitrogen and trace elements like Ozone and Argon. The atmosphere of gaseous planets is more problematic. Any available water is evaporated into the atmosphere and all the byproducts (perhaps oif previous ecosystems), such as methane and nitrogen are volitized into a soup of indigestible products hugging the surface and killing off any possibility of life(as we know it). Most other planets could never have supported life.
Sad but true. So I am asking, what if the planet Earth, lucky to find itself in a gentle zone, (called Goldilocks by planetary scientists "not to hot, not too cold", and I might add, not too filthy), is in bigger trouble than any one has contemplated?
What if the project of human industrialization has, in less than two hundred years, converted the prevailing atmosphere of the planet Earth into a soup of the byproducts of fossil fuel imolation and set the planet on an inexorable course towards a methane + nitrogen atmosphere that cannot, and will never again, sustain a form of life any ways near the highly structured human species, let alone frogs and butterflies?
