They do have some funny ones at the Heartland Institute and doesn't Anthony Watts love 'em. This one's called Dennis T. Avery and apparently he's been an ice age comether for some time. He even scored a Wikipedia entry to prove it :)
Not only that, but he scored a ClimateProgress post all to himself when he couldn't tell the difference between growth and growth rate. And a SourceWatch entry. Now he's really hit the bigtime with a HotWhopper entry - but it's not all for himself. Ice age comethers are a dime a dozen at WUWT.
Dennis used to work for the government - the US Department of Agriculture. (Deniers forgive him because he's one of them.) I wonder how it feels to be a laughing stock among his former colleagues. It's easy to infer from his WUWT "guest essay" (archived here) that he doesn't accept the greenhouse effect. He was writing about an article by Geoffrey Parker in the NY Times. The article itself was about how climate change contributed to wars and social unrest in the past and postulated that it may well do the same as the world warms and food production is affected. Dennis wasn't buying it. I think he figured that droughts only happen when there's a cold spell or something like that. He wrote:
Almost all past agricultural and cultural collapses occurred during “little ice ages,” not during our many global warm periods.
Now I don't know if that's right or wrong but I do know that the way things are going, humans will never have experienced a global warm period like the one we're heading towards. The blue line in the chart below covers the period since civilisation. The red line is what's projected over the next few decades. Probably before this century is out.
|Adapted from Jos Hagelaars|
The danger is the cold, chaotic weather of the “little ice ages” themselves. That will shrink agricultural zones and shorten growing seasons. Another such icy period is inevitably coming, though not likely in the next two centuries, if past cycles are an accurate guide.
Regardless, for the next 20-25 years, humanity will likely be in another cooling period, caused by the sun’s reduced energy output and the Pacific Decadal Oscillation. We are about 150 years into the modern warming. Since the shortest of these warm periods during the Halocene was 350 years, and they generally last 350 to 800 years, it is unlikely that we will enter another Little Ice Age for a couple more centuries.
That's it. He's doing climate by numbers - and not very useful numbers at that. He thinks that there are some sort of long term cycles lasting between 350 and 800 years - which is a nice wide margin for him, isn't it. He offers no evidence for his claim and it's not one I've ever come across before.
He's wrong of course. We aren't due for a major glaciation for around 50,000 years and as for mini ice ages, only if there's a few supervolcanic eruptions or an all-out nuclear war.
Anthony thinks that ice doesn't melt in the heat - again
Meanwhile, Anthony Watts has written another silly article (archived here) about how ice doesn't melt when it gets hot. Oh, he doesn't say so in so many words. What he does is claim that seas won't rise over the coming decades, or not by much. He reckons that the rate of sea level rise is currently linear (he's wrong) and that it won't change as West Antarctic ice slips into the ocean. Anthony decided on the following senseless headline:
Making sense of senseless sea level scares in Norfolk Virginia – 60% of the rise is from subsidence, the remainder from landfill settling
It was Anthony's own article that was senseless, not the fact that seas are going to rise quite a lot. He didn't manage to make much sense, as usual. I've written enough about his fantasies on that score already (such as here and here and here and here) so I'll send you over to Tamino's excellent take down.
Before you go - or afterwards, if you want to see a couple of very good videos about sea level, try these two.
From the WUWT comments
Just a small selection today. First Goldie discusses the impending ice age that won't cometh for a very long time and says:

That sounds about right. But at the moment we have a group of people who are determined to blame everything on too much Carbon Dioxide in the atmosphere. I suspect the North Atlantic will freeze over and this group will still be trying to assign it to Carbon Dioxide. The reality is of course that these people belong to an interesting cabal who are anti any form of carbon based energy and instead would prefer to have half the population of the planet freeze to death whilst trying to use so called renewables. Indeed their thinking is so odd that they would probably prefer it if half of the population froze to death.

Do these people actually believe the ice caps could melt while the temperature remains far below freezing even with the 3 degree worst case projection ? It appears that only the dumbest portion of our population are hired by the media.
