"Ample physical evidence shows that carbon dioxide (CO2) is the single most
important climate-relevant greenhouse gas in Earth¡¯s atmosphere"

First phrase, first lie. The single most important climate-relevant blah
blah blah is water vapour,  not CO2 by a great margin. It makes about 90%
of the global warming effect.

I mean that this is a lie because they supposedly are scientists and they
must know it.

Anyway, this is bad news for those that, like me, receive  Exxon checks, we
need more antropogenic alarmists  ;))))

This list is becoming truly about  everything.
