Ah, just remembered an argument put forth on the other (now closed thread), which was the impact of the ocean's CO2 bindings. (The poster did indeed bring up some useful and logical points).
Anyway, as much as the life of the sea brings to the balance, our co2 ppm's are still rising fast, and heading for a record.
It was interesting to see what was posted here before, that the SL was once 100 metres higher. That would mean no polar caps at all (?) and unsurvivable conditions on barren land near the middle. It also roughly confirms how high the SL would be without caps. How many of you guys live above 330 feet?
That would put the doomsday theory to rest (Venus atmosphere), however the impact of massive forests is yet to be considered, since they have a great cooling effect.
So, in short, good news. And yet not. For if we keep pumping greenhouse gases, the caps will melt, the methane stored in the permafrost will be released, AND we have an all time low of forests, we will have a setup that hasn't been here for hundreds of millions of years. And back then, things were indeed wild. If you then add the increased solar activity to the equation, - and thereby or as well the natural upswing in temperature that sme claim, it makes things a lot worse. So, worse than bad. Oh my.
You see, polluted oceans as well as deforestation, spiced with greenhouse gases and dressed with raised solar activity adds up to a devil soup. To avoid that sour dinner, more maneuvers have to be made.
