“They will not accept that the volcano leads to cooling.”
How could they do that when Mt. Pinatubo in 1991 dropped the average temperature of the globe by some four degrees F? There is evidence all over the place that shows volcanoes do cause cooling although it is usually just temporary.
Evidence does not matter. What matters is that Al Gore’s investments in carbon credits are worthless and they need a new international agreement to shore up the value of his assets. Failing the international agreement, the only way to save him is to transfer wealth from American taxpayers to Al Gore’s firms.
