That being said...one of the FIRST things strangers inevitably ask me when they find out my profession is about AGW. They get an EAR full. I have the presentation down to about 6 minutes. A couple once asked me what I thought about "global warming" on a ski-lift at Breckenridge. They had NOWHERE to go. They were New Yorkers. Libs.
The LAST question I ALWAYS ask is this: "But lets ASSUME (after ALL I have just said) that I am wrong and AGW is happening: In the HISTORY of mankind...and we have multiple relatively rapid rises in global temps...The Egyptian Warm Period...the Roman warm period...the medieval warm period...Now...in the HISTORY of mankind...WHEN has global WARMING EVER been a negative? It's only global COOLING that's been a climate negative and stopped civilization...not GW. GW has always led to humanity THRIVING. Can you or has anyone EVER shown us how GW would have an overall NET negative impact?
"No...because it wouldn't. Wouldn't you like a warmer winter? Don't you think the ships would like easier passage through the ice packs? Wouldn't that bring the cost of goods down?"
Stunned Silence.
A warmer Earth would have Siberia and Canada becoming viable agricultural areas, with a huge impact on being able to feed the world. Warmer oceans mean more evaporation and more rainfall, with fewer droughts.
Probably never. The current average temperature of Earth is 58 degrees. Scientists used to call periods of warming in Earth's history optimums. I don't know if they still do.
How about sharing your six minute presentation?
Good talking points!
But the polar bears...what about the polar bears!?
Priceless ! Wish I could have been there to witness this one. LOL
