If you actually read my post, you'd see I am considering any near future Greenland sheet ice melts as evidence, of passing a tipping point. You don't understand tipping points, and you aren't asking questions, about this.
If you actually paid attention to any of my posts, rider, you would admit I claim back-radiation is happening, but you apparently don't believe in back-radiation OR open atmospheric greenhouse effect, based on behavior, of proliferation of molecules, with three atoms, or more.
You provided a non-scientific website and an experiment, to test 2nd Law of Physics phenomena, which doesn't disprove back-radiation. Your posse ranted and posted troll-scat.
We are already suffering extinctions, past 100 x normal, see links, above. We will suffer Mass Extinction Event 6, by any reasonable projection, of modern outcomes. Do you have any REAL questions? I don't see any scientific method, at this site, worth a lot of replies.
If the problem of melts proliferates, more cold water will bring relative acidity, to more eggs, little fish, corals, and oysters, which will affect the ocean's food chain. Oyster die-offs now happen, as cold upwellings disturb shell formation, of oyster larvae. You may have noticed cod aren't recovering, and bluefin tuna are now threatened. Heard of FISH?
I guess fish aren't troll chow.
