Cold ’nuff for ya?

This has been getting a lot of (pretty justified, IMHO) attention:

The total amount of cooling ranges from 0.65C up to 0.75C — a value large enough to wipe out nearly all the warming recorded over the past 100 years. All in one year’s time. For all four sources, it’s the single fastest temperature change ever recorded, either up or down.

I’ve been skeptical that a decade and more of warming data was not really enough to prove anything, so one year of cooling data is no better. But it’s anecdotal evidence that does a lot to derail much of the anecdotal evidence the global warming crowd like to toss around as conclusive fact.

All along I’ve thought that the largest effect on earth’s global temperatures was the sun. I still think that, and it seems that more and more evidence is coming to light that supports this.

And if you think major Global Warming scenarios were scary, you had better not take a look at some major Global Cooling scenarios. You’ll pine for the days when the Ross Ice Shelf was disappearing, rather than the days that the Ross Ice Shelf threatens to gobble up southern Australia.


  1. Read about the Little Ice Age – villages crushed by rapidly advancing glaciers, failed crops, mass starvation (in Europe and North America), plagues, Viking colonies wiped out. Makes all the Global Warming scenarios look mild.

  2. With the publication of the article in Science, I gained significant credibility in the community of scientists working on climate change. They thought I was one of them, someone who would pervert science in the service of social and political causes. So one of them let his guard down. A major person working in the area of climate change and global warming sent me an astonishing email that said ‘We have to get rid of the Medieval Warm Period.’

    From here. They probably feel the same way about the LIA because they both suggest there’s climate variability outside of CO2 influence, and because if the LIA is a fact then it makes 20th century warming seem like more of a recovery back to normal temperatures than anything else.

  3. Nicholas: I would think you guys would want to be on top of this more than anyone…After all, my scenario has the Ross Ice Shelf marching on Australia.

  4. You may have some problems with the influx of Canadian refugees in such a scenario too :) Realistically though, if that happens, all we can do is (a) take some lessons from Siberians or (b) move north. (b) isn’t very difficult, the only problem is having to rebuild the infrastructure. There’s plenty of hot northern areas to move to. Similarly, you have places like Texas. But really, is there anything we can do either way? If not all we can do is watch the situation and if necessary make preparations. I think we may be looking at another ‘little ice age’ at some point (it’s presumably inevitable given the variations which seem to happen with or without our actions). But given that we have much better technology now, while I think it will cause some problems – especially reduced crop yields – we can likely ride it out.

  5. … or we could have another ‘Medieval Warm Period’ (although hopefully with less Viking invasions). Who knows? Either way we’ll just have to find some way to adapt.

  6. While there is fair evidence to support the notion that the warming during the first half of the 20th century was due primarily to increases in Solar irradiance, I don’t see any similar such change in the Sun to explain the warming over the past 50 years. evidence: (click on graph on right) Climatologists a year or two back predicted that global mean temperatures would be cool-ish for a few years before heating up. They also predicted that weather events would get more extreme as energy builds up in the climate system, and as more water-vapor is available throw around as rain and snow. Also the Ross sea does not face Australia (New Zealand yes…kinda).
