“Rush Limbaugh, more than any other individual, is responsible for shifting conservative opinion to deny the existence of global warming.”

 -John K. Wilson, author of The Most Dangerous Man in America: Rush Limbaugh’s Assault on Reason.

Climate denier, and fatally, tobacco denier, Rush Limbaugh, died this week from lung cancer.
Yeah, made me think back to that time I talked to him.

Some time later in the nineties, maybe ’97?
I had been following climate science for 20 years, and Jim Hansen’s work since 1981, and I understood, in a rudimentary way, what the mainstream science was telling us.
Scientists, as of 1995, had detected a “discernible” human influence warming the planet.
Hansen’s model had accurately predicted the planetary response from the Mt Pinabubo eruption, a major validation of the (by today’s standards) primitive climate models Hansen relied upon. Still lots to discuss, but it looked like this mechanism was real, and the process was happening.
I knew, as someone that grew up outside, on snow and water, that things were certainly changing in my upper-midwest neck of the woods.

On that particular day, Friends of the Earth had published a full page ad about climate change in USAToday, with a speculative “weather map” for the 2020s. It depicted a heat wave with a shocking temperature of 124 F in California.
(This past summer the temperature hit 130 in the desert, and an insane 110 F in LA, near the ocean.

Ridiculing the ad, Limbaugh launched into a climate denial rant, listing the most popular nonsense memes that we are all familiar with. And anyway, he said, even the most extreme eco-nuts were only talking about a few degrees rise in global temps, so obviously this ad was just more over-the-top scare tactics, he fumed.
Taking a breath, he invited “any environmentalist out there who can defend or explain this, to call in. I want to talk to you.”

Hunched over my keyboard, and listening as I struggled to nudge along a barely-alive communication business – I took up the challenge, and – incredibly – got through.
A voice asked me if I was indeed, the environmentalist Rush was asking for – I assured him that was me.
“Hold on for Rush” the voice said.

A few minutes went by, while I took some deep breaths and stretched.
Suddenly, the familiar voice was on the line.
“Ok, we have Peter from Midland, Michigan. Are you a greenie? an enviro?”

“Well, I often wear sandals, I hug trees when I’m climbing them, but not, you know, in a weird way.
And I’ve been known to order the tofu in my veggie stir fry.”
That was good enough.
“Alright, so explain this ad to me. The claim is made here that in the 2020s, we’ll see temperatures of 124 degrees Fahrenheit – but even Al Gore says the planet is only warming by a degree or so. So this is more scare tactics, right?”

After watching several videos of the breakup of Beaufort sea Ice during the dead of winter, I decided to contact a leading ice expert, Walt Meier of the National Snow and Ice Data Center, for analysis and perspective. I mixed his comments in with the increasingly-on-the-same-page warnings from his fellow scientists around the country.

I’ll post our full conversation later in the week.

Flogging the Scientists

March 15, 2010

As a nonscientist, it’s daunting for me to work thru the huge volume of information on global climate change. I’ve found that the most reliable scientific information comes from respected peer reviewed science journals .

But journals have lots of big words, and lots of small print, and very few illustrations to make it easy for me. You can see why climate deniers don’t like them. But that’s where the facts are.

How can you tell a good science journal?

In the many responses I get to these videos, it appears that a number of people want to deny, or are not even aware, that there is a scientific foundation to the overwhelming consensus on climate change.

In fact, the science is built on thousands of publications and many decades of observation.

In this video we’ll go over some of the fundamental discoveries, the basic facts that we know beyond a doubt, about global warming.  Of course, many people will never believe science, because they believe that anything that challenges their world view, is all part of a secret, global conspiracy.

One of the enduring myths of climate denialism is that global warming stopped sometime in the last decade. I see it in the blaring headlines of pseudoscience websites, in comments on my videos, even some of our most “distinguished” journalists have been taken in.
