As far as I'm aware they're not trying to say this is global warming right now because they don't understand how this happened. I'm not really interested in debating the qualifications of the many scientists currently trying to figure this out.
I am.
It seems a no-brainer to me that, since there are underwater volcanos under the Antarctic ice shelf.... and since they know that there are underwater volcanos under the Antarctic ice shelf....
that they might suspect that could be a cause. But instead, they have "no clue"...lol. It's hilarious... really. Scientists always have a theory.... but in this case, nada. Makes me wonder...
