Bullshit. They can repeat it, but offer NO Proof.
Science demands verifiable proof, not two blowhards, spouting their religious beliefs.
Until one of these snake oil salesmen can:
1) Describe to me the mechanism by which the last ice age ended (with proof that there description is plausible);
2) Describe to me the mechanism that the claimed temperature increases have changed during the last 150 years or so of accurate recording of temperature and weather events; and
3) Provide solid evidence that the same mechanism is not in place today, then...
I call B-—$#!+ and refuse to give these people any further authority over our way of life.
