Climate Models Worse than Random Guesses

From statistics guru Ross McKitrick:

A few years ago a biologist I know looked at how climate change might affect the spread of a particular invasive insect species. He obtained climate-model projections for North America under standard greenhouse-gas scenarios from two modelling labs, and then tried to characterize how the insect habitat might change. To his surprise, he found very different results depending on which model was used. Even though both models were using the same input data, they made opposite predictions about regional climate patterns in North America.

 This reminded me of a presentation I’d seen years earlier about predicted changes in U.S. rainfall patterns under global warming. The two models being used for a government report again made diametrically opposite predictions. In region after region, if one model predicted a tendency toward more flooding, the other tended to predict drying.

 Just how good are climate models at predicting regional patterns of climate change? I had occasion to survey this literature as part of a recently completed research project on the subject. The simple summary is that, with few exceptions, climate models not only fail to do better than random numbers, in some cases they are actually worse.

That is just the summary. Read the whole thing.

The point is that the models simply do not work when it comes to predicting changes in global (or even regional) climate. But it is predictions based on these same models which have been used to justify crippling legislation like the carbon dioxide tax, and spending billions of dollars to solve a problem which doesn’t exist.

Bailouts End Here

The end result of quantitative easing (governments printing money to pay their bills):

Lots of money. Nothing to buy.

 

100 Billion dollars. Three eggs. Go Keynes!

In 1980, the Zimbabwe dollar was worth more than the US dollar. In 2009 Mugabe’s government printed notes with a face value of 100 trillion dollars. At that time they were worth about $300 US. Shortly after that, Zimbabwe abandoned its own currency. Zim dollars were worth less than toilet paper, so that is what people used them for.

That is the end point of excessive government spending; an economy down the toilet.

Fairfax Comedy Hour

Ha, ha, ha, ROFL.

Wayne Swan says Gina Rinehart’s interest in Fairfax is a threat to democracy. No Wayne, that would be a minority government that introduces destructive legislation it promised it would not introduce, then spends millions on bribes to retain power.

Communications Minister Stephen Conroy (who?) says Gina Rinehart is not entitled to trash the Fairfax brand for other shareholders. No Stephen, she doesn’t need to. The crony crowd of Karl worshiping clod-hoppers who call themselves Fairfax journalists have been doing that for years.

Meanwhile, back at boring central, David Marr, who seems to find it difficult to think rationally at any time, offers the following brilliantly irrational analysis:

The charter which gives journalists complete control over the Fairfax product “Has protected the assets of Fairfax. It has protected the readers, it’s protected the community and it’s also protected the journalists and that is now what is under direct challenge by Mrs Rinehart.”

He may have a point about the readers, if he means they have been protected from ever having to read an opinion that might cause them to rethink their own.

But “has protected the assets of Fairfax”? Only if protecting means acting in such a way that the share price has fallen to about ten per cent of what it was five years ago, and two state of the art print plants must be sold off to keep the company going.

“Protected the journalists”? Really? Almost all daily papers have seen declining circulations over the last ten years. But Fairfax papers are right at the bottom of the pile. They offer a product few people want. That does not lead to a secure work environment for journalists.

If you grow pink mushrooms, and they sold well for while but now they don’t, you can’t just sit around whining about it and demanding the government support your right to keep growing pink mushrooms. Grow something else, something people want. It’s the same with newspapers. You do not have the right to keep producing a product nobody wants. Well, you do, you just don’t have the right to demand people pay for it.

Journalists, readers and public will all be better served (and protected, whatever that means) by a Fairfax press with a sound business model, and a board that encourages, no, demands, the production of news and information services that offer Australian consumers worthwhile products at a reasonable price.

But hey, let the Fairfax journos go on strike with the printers. No papers is a great way to undermine the share price even further, and maybe some Age readers will pick up another paper by mistake and discover what they have been missing.
