One of my many jobs as a newspaper journalist included interviewing smart, interesting people about specialized, controversial subjects like climate change.

In 2007 I interviewed Timothy Ball, a Canadian climatologist who has been fighting the good fight against global warming insanity for years. He is a climate skeptic with a Ph.D. in climatology from the University of London who taught at the University of Winnipeg for 28 years.

It’s easy to see why Ball has made no friends among global warming alarmists. He says that the widely propagated “fact” that humans are contributing to global warming is the “greatest deception in the history of science.”

Like most sensible scientists, he says there’s global warming but it’s caused by the sun, not mankind, and that its effects will be good for us earthlings, not catastrophic.

When I spoke to Ball in 2007, the good-humored Canadian pointed out that his home island, Victoria, in British Columbia, was connected to the mainland 8,000 years ago when the sea level was 500 feet lower.

He and I talked about global warming, ice ages and sea levels. Here are highlights:

Q: What is your strongest or best argument that global warming  is not “very likely” to be caused by SUVs and Al Gore’s private planes?

A: I guess the best argument is that global warming has occurred, but it began in 1680, if you want to take the latest long-term warming, and the climate changes all the time. It began in 1680, in the middle of what’s called “The Little Ice Age” when there was three feet of ice on the Thames River in London. And the demand for furs of course drove the fur trade. The world has warmed up until recently, and that warming trend doesn’t fit with the CO2 record at all; it fits with the sun-spot data. Of course they are ignoring the sun because they want to focus on CO2.

The other thing that you are seeing going on is that they have switched from talking about global warming to talking about climate change. The reason for that is since 1998 the global temperature has gone down — only marginally, but it has gone down. In the meantime, of course, CO2 has increased in the atmosphere and human production has increased. So you’ve got what Huxley called the great bane of science — “a lovely hypothesis destroyed by an ugly fact.” So by switching to climate change, it allows them to point at any weather event — whether it’s warming, cooling, hotter, dryer, wetter, windier, whatever — and say it is due to humans. Of course, it’s absolutely rubbish.

Q: What is the most exaggerated and unnecessary worry about global warming or climate change?

A: I think the fact that it is presented as all negative. Of course, it’s the one thing they focus on because the public, with the huge well of common sense that is out there, would sort of say, “Well, I don’t understand the science, but, gee, I wouldn’t mind a warmer world, especially if I was living in Canada or Russia.” They have to touch something in the warming that becomes a very big negative for the people, and so they focus on, “Oh, the glaciers are going to melt and the sea levels are going to rise.” In fact, there are an awful lot of positive things. For example, longer frost-free seasons across many of the northern countries, less energy used because you don’t need to keep your houses warm in the winter.

Q: Is the globe warming and what is the cause?

A: Yeah, the world has been warming since 1680 and the cause is changes in the sun. But in their computer models they hardly talk about the sun at all and in the IPCC summary for policy-makers they don’t talk about the sun at all. And of course, if they put the sun into their formula in their computer models, it swamps out the human portion of CO2, so they can’t possibly do that.

Q: Is the rising CO2 level the cause of global warming or the result of it?

A: That’s a very good question because in the theory the claim is that if CO2 goes up, temperature will go up. The ice core record of the last 420,000 years shows exactly the opposite. It shows that the temperature changes before the CO2. So the fundamental assumption of the theory is wrong. That means the theory is wrong. … But the theory that human CO2 would lead to runaway global warming became a fact right away, and scientists like myself who dared to question it were immediately accused of being paid by the oil companies or didn’t care about the children or the future or anything else.

Q: Have you ever accepted money from an oil company?

A: No. No. I wish I did get some. I wouldn’t have to drive a ’92 car and live in a leaky apartment bloc.

Q: Why are sea levels rising and should we worry?

A: Sea levels have been rising for the last 10,000 years. In fact, 8,000 years ago, sea level was almost 500 feet lower than it is today. It’s been rising gradually over that time. It’s risen very slightly in the modern record, but it has risen no more rapidly than it has in the last 8,000 years. One of the factors that people forget is that most of the ice is already in the ocean, and so if you understand Archimedes’ Principle, when that ice melts it simply replaces the space that the ice occupied — even if the ice caps melt completely. What they do is they say if we estimate the volume of water in Antarctica and Greenland, then we add that to the existing ocean level. But that’s not the way it works at all. But it does work for panic and for sea-level rises of 20 feet, like Gore claims.

Q: Why are the sea levels rising, just because we are in a warming period?

A: Yes. We are in an inter-glacial. Just 22,000 years ago, which is what some people can get their minds around, Canada and parts of the northern U.S. were covered with an ice sheet larger than the current Antarctic ice sheet. That ice sheet was over a mile thick in central Canada. All of that ice melted in 5,000 years. There was another ice sheet over Europe and a couple more in Asia. As that ice has melted, it’s run back into the oceans and of course that’s what’s filled up the oceans. But if you drilled down in Antarctica, you go down almost 8,000 feet below sea level. That ice below sea level, if it melts, is not going to raise sea level.

Q: Is there any aspect of global warming alarmism that you are worried about?

A: There are a couple of very minor things. I’m interested in and need more research done on commercial jet aircraft flying in the stratosphere. The research that’s been done so far says no, it’s not an issue, but I think the jury is out on that still.The other concern I have is that we’re totally preparing for warming. The whole world is preparing for warming, but I mentioned that we have been cooling since 1998 and the climate scientists that I respected — particularly the Russians and Chinese — are predicting that we’re going to be much, much cooler by 2030. So we’ve got completely the wrong adaptive strategy.

Q: Is it not inevitable that we will have another ice age?

A: Yes, I think there is another ice age coming, because the major causes of the ice ages are changes in the orbit of the Earth around the sun and changes in the tilt of the Earth. Those are things we’ve known about for 150 years.

Q: If someone asked you where he should go to get a good antidote on the mainstream media’s spin on global warming, where should he go?

A: There are three Web sites I have some respect for. One is the one I helped set up by a group of very frustrated professional scientists who are retired. That’s called Friendsofscience.org. It has deliberately tried to focus on the science only. The second site that I think provides the science side of it very, very well is CO2Science.org, and that’s run by Sherwood Idso, who is the world expert on the relationship between plant growth and CO2. The third, which is a little more irreverent and maybe still slightly on the technical side for the general public, is JunkScience.com.

Q: If you had to calm the fears of a small grandchild or a student about the threat of global warming, what would you tell him?

A: First of all, I probably wouldn’t tell him anything. As I tell audiences, the minute somebody starts saying “Oh, the children are going to die and the grandchildren are going to have no future,” they have now played the emotional and fear card. Just like in the U.S., it’s almost like the race card. It’s not to say that it isn’t valid in some cases. But the minute you play that card, you are now taking the issues and the debates out of the rational and logical and reasonable and sensible and calm into the emotional and hysterical.

To give you an example, I was talking to a group in Saskatoon and a woman came up after and she said, “I agree with you totally. We were having a party for my 7-year-old. I went into the kitchen and there was a bang in the living room. I went back and a balloon had exploded. The kids were crying and I said, ‘Why are you crying?’ And they said, ‘There’s going to be another hole in the ozone.’”

It’s completely false. There never were holes in the ozone, by the way. But when we start laying those kinds of problems onto shoulders that are very narrow, that is criminal. My comment to her was, I said, “Look, let the kids get on with the party. Give them another beer. Let ’em enjoy themselves.”

So I wouldn’t raise these kinds of fear with the children. What I would do with my children and grandchildren is what I’m trying to do with the public and say, “Look, here’s the other side of the story. Make sure you get all of the information before you start running off and screaming ‘wolf, wolf, wolf.’”
