Quote:North Carolina tries to outlaw climate models

Political satirist Stephen Colbert's solution to unfavourable climate science is simple: "If your science gives you a result that you don't like, pass a law saying that the result is illegal. Problem solved."

Legislators in North Carolina are apparently of the same mindset. When a state-appointed commission announced that North Carolinians could expect 39 inches of sea-level rise by 2100, the Senate responded with a bill that legally prevents the Division of Coastal Management from using the climate model that forecasts fast-rising sea levels. Instead, the legislators would like to see coastal management use only a linear model, which predicts a mere 8-inch rise by the same year.

The 8-inch model, based solely on historical records from the last 100 years, flies in the face of modern climate science. Sea level rise is due to a combination of climate-driven factors: warmer temperatures cause ocean water to expand, and rising temperatures are melting the Arctic and Antarctic ice caps. The combined feedback makes for exponential – not linear – growth. Yet the North Carolina bill states: "Rates of sea-level rise may be extrapolated linearly to estimate future rates of rise but shall not include scenarios of accelerated rates of sea-level rise."

"This is unprecedented," says Orrin Pilkey, professor emeritus of geology at Duke University in Durham, North Carolina. "It's the first time a law has dictated the shape of a curve."

NC-20, the group behind the bill, has argued that incorporating the 39-inch predictions would be an enormous economic burden on coastal communities. "The legislature has declined to face the problem of what we're going to do about it, and instead has attacked the science," contends Pilkey.

Though the bill passed the Senate by 34 votes against 11 and seems poised to make a smooth run through the House, Pilkey and other climate scientists are hoping that the governor will veto it.

Which data is this that is being made to go away?

There are time blocks (100s of thousands of years) from some geological eras where the carbon dioxide levels are much higher than anything we have now, but evidence points to temperatures in general being lower than now. However, the climate experts who push the climate change don't bring those up, because they don't fit the model that they're pushing on everyone.

Some of this came out when some emails between researchers were leaked several years ago, talking about data they were going to ignore, because it didn't fit their pet theories. No, I don't have links, but it's not hard to find.

Fact is, it's become a political thing more than a scientific one, and, those researchers basically buried the data that didn't fit so they could keep their funding. If the experts on this were more united, I'd give them more credence, but, there's lots of climate experts out there that disagree with the one the news media likes to push.

Quote:So based on what is known about climate change, it makes sense that if global sea levels do rise, that the coastal cities be thinking about the future even if its, ten, fifty, a hundred years from now.

Quote:I hate how the social security debacle has shown how inept the current and former motley crew is we have in office; if they didn't touch that money, or better yet invested it to earn more instead of constantly taking out of social security, then the SS system would not be in dire straights. But nobody can see more than one election term into the future, and that's a fact!

Quote:And this is what makes this entire law a huge cachinnation of imbeciles because if water levels do rise unexpectedly, they will be fully unprepared. "Ten years from now? Let them worry about it then. I won't be in office that long. One-hundred years from now? Well hell, sunny, I won't even be alive then. Who cares?!? I will have used up all the natural resources I wanted to by then anyhow. Makes no difference to me." It's the unwillingness to look into the future that I'm dismayed about.

He isn't a scientist, neither by academic qualification nor by professional experience. He has no scientific degrees - his education is in journalism. He has never worked on any part of climate science, either from the empirical or theoretical side.

He is a TV personality. Colour me unimpressed. Even among AGW skeptics, one can find overwhelmingly more qualified experts.

From what I understand, we have good instrumental temperature data going back into the 19th century, although obviously the coverage is not as good. Climate has always been of interest to scientists, and one does not require a theory of global warming to justify collecting temperature data on different parts of the world.

As for checking, the series can be compared against known (measured) temperatures in more recent times, and also against one another. All climate data is regional, peculiar, and fuzzy, but it would be strange indeed for all of our sources to tell roughly the same temperature story, independently, if they were all idiosyncratically biased.

Rather the opposite. The evidence for climate change (that is, the fact that the climate is observably changing) is completely overwhelming. What is in question is *why* - what are the factors (climate forcings) that are causing it to change. What contributes, and in what measure? To what extent are humans the cause of the change (anthropogenesis)? These are theoretical matters - that is, we try to explain the facts with models and concepts that help us to understand and predict.

But perhaps the difficulty is, as Quark rather pithily pointed out, the difference between the colloquial and scientific definitions of "theory" and "fact." Theories do not "become facts." Gravity is still a theory, even though it is uncontroversial.* Theories describe abstract causal relationships, which are then tested with evidence. (This error is so common, wiktionary even has it in the usage notes for the word theory!)

*Well, its reconciliation with quantum mechanics obviously isn't. We need a new theory! But that doesn't stop the earth from orbiting the sun, or rocks from falling when you drop them.

If, by "meteorologist," you mean "scientist working in the field of weather," then sure.

But he isn't a meteorologist in that sense. He's the weather guy on the local news. This is what he does: standing in front of a green screen, grinning like a game show host, and showing you whether it will be sunny or rainy tomorrow. Necessary though it may be, that's not science, and there's nothing about that job that teaches you anything relevant about climatology.

Really? For those critics who are actually in the field of climate science, they don't seem to be suffering too terribly. Richard Lindzen is the Alfred P. Sloan professor of meteorology at MIT. (I'd kill for a named chair at MIT, and if that's what being a pariah is, then sign me up!) Judith Curry is a chair at the Georgia Institute of Technolology. Most other critics are from other fields (notably geology and astrophysics), but seem to be doing just fine.

It's not exactly a popular view, and no doubt their views will come under sharp criticism for their peers. (Not unlike, say, a Marxist in an economics department, or a steady-state universe proponent in astronomy.) But there's a long way between that and being a "pariah," or being "ruined."
