Method without Science,

or method

… “Opps!”

Seeing the recent “Science without method” post at Climate Etc I opted to first read the Nicol paper it was discussing before reading Dr Curry’s discussion of it.

The article alleges to highlight failures of climate change science, and in an obviously unintended way both it and Curry’s discussion of it does.

To give credit where credit is due, the exercise led me to rethinking how we frame the question of our current impasse. How it is possible for drivel like Nicol’s to somehow be taken seriously by anyone, never mind winding up actually influencing policies of countries.

First let’s get some context. In his paper Nicol said:

Yet in contemporary research on matters to do with climate change, and despite enormous expenditure, not one serious attempt has been made to check the veracity of the numerous assumptions involved in greenhouse theory by actual experimentation.

greenhouse theory“, seriously? Has he not read any scientific literature post-1860?

That aside, this is just idiotically wrong as a general statement. Can he cite any specifics? Loaded as it is with qualifiers he would no doubt cite all of the relevant reserach (which he is clearly not familiar with, or simply doesn’t understand) as not “serious” attempt(s) (ie No True Scotsman fallacy).

BPSDB The recent tornadoes in the United States have lead to a resurgence of articles talking about the link between extreme weather, natural disasters and climate change. If you are an interested member of the general public you are undoubtedly confused as the two sides of the debate seem to be making opposing claims, and both seem to have some science to back them up.

I’d like to talk a bit about why there is this confusion and what it means in practical terms for you and me. Then I’d like to discuss the opinion of the folks who take this issue very seriously indeed. No, I don’t mean the scientists, much more seriously than that – I am referring to the insurance industry.

The critical phrase is “seem to be making opposing claims“, because for the most part they are not. The climate change Deniers erroneously characterize the science based reports as ascribing the various tornadoes, storms and what have you as being caused by or linked to climate change. That is not what the ones I sampled were actually saying.

If you read the various reports they correctly note that given the current state of our knowledge it is impossible to directly link the recent extreme weather to climate change. It is also impossible to definitively say there is no link; that’s how uncertainty works.

Now from what I can gather it is probable that the influence of climate change on the most recent spate of tornadoes in the US south west was very small to none, but that’s not the end of the story.
