Dr. Hayward was my guest on yesterday’s show for three segments. The audio is here. Bottom lines:
The earth is warming a bit. It has done so in the past.
We humans have contributed to the warming though it is impossible to say how much.
Projections of catastrophic or even serious consequences are unreliable.
Up to 2 degrees of warming (we have had .8 in recent decades) may in fact benefit the globe.
The prescriptions offered by Al Gore and others would themselves be catastrophic for hundreds of millions of people.
