Henrik Svensmark – Politics and Prosperity

UPDATED 02/12/14 (related reading added)

I am loath to write again about AGW, so convinced am I that it is a “scientific” myth. But the myth has a large, vociferous, politically motivated, and almost-unshakeable following. So here goes…

Watt’s Up With That? notes

a Technical University of Denmark press release [about] what looks to be a significant confirmation of [Henrik] Svensmark’s theory of temperature modulation on Earth by cosmic ray interactions. The process is that when there are more cosmic rays, they help create more microscopic cloud nuclei, which in turn form more clouds, which reflect more solar radiation back into space, making Earth cooler than what it normally might be. Conversely, [fewer] cosmic rays mean less cloud cover and a warmer planet as indicated here. The sun’s magnetic field is said to deflect cosmic rays when its solar magnetic dynamo is more active, and right around the last solar max, we were at an 8000 year high, suggesting more deflected cosmic rays, and warmer temperatures. Now the sun has gone into a record slump, and there are predictions of cooler temperatures ahead….

The new paper is:

Response of cloud condensation nuclei (>50 nm) to changes in ion-nucleation” H. Svensmark, Martin B. Enghoff, Jens Olaf Pepke Pedersen, Physics Letters A 377 (2013) 2343–2347….

What about the seemingly high rate of increase in temperatures in recent decades? As I say here,

It should be quite evident by now that the warming trend of the past thirty-odd years merely coincides with the rise in human activity (as measured by population) but is not explained by the “greenhouse” effect…. There are alternative and compelling alternative explanations for the warming trend, including the influence of solar activity summarized above….

What else explains the apparent (but exaggerated) warming trend of the past thirty-odd years (a “trend” that ended more than 15 years ago)? Poorly sited weather stations and urban heating are the two main culprits.

P.S. So much for the prematurely predicted disappearance of the Arctic ice cap: here and here.
