Not disingenuous at all this article, oh no. Let's take some excerpts:
"MASSIVE GLOBAL COOLING process discovered as Paris climate deal looms; 'Could explain recent disagreements'"
"... global temperatures have actually been stable for more than fifteen years, a circumstance which was not predicted by climate models and which climate science is still struggling to assmilate"
"...Global models at the moment assume total emissions of isoprene from all sources - trees, plants, plankton, the lot - of around 1.9 megatons per year. But, according to the new research, the newly discovered "abiotic" process releases as much as 3.5 megatons on its own - which "could explain the recent disagreements" between models and reality."
But let's look at the press release that he lifted this quote from:
"Isoprene is a gas that is formed by both the vegetation and the oceans. It is very important for the climate because this gas can form particles that can become clouds and then later affect temperature and precipitation. Previously it was assumed that isoprene is primarily caused by biological processes from plankton in the sea water. The atmospheric chemists from France and Germany, however, could now show that isoprene could also be formed without biological sources in surface film of the oceans by sunlight and so explain the large discrepancy between field measurements and models. The new identified photochemical reaction is therefore important to improve the climate models."
"Thus, it is now possible to estimate more closely the total amounts of isoprene, which are emitted. So far, however, local measurements indicated levels of about 0.3 megatonnes per year, global simulations of around 1.9 megatons per year. But the team of Lyon and Leipzig estimates that the newly discovered photochemical pathway alone contribute 0.2 to 3.5 megatons per year additionally and could explain the recent disagreements."
So this reference to a discrepancy between observations and models appears to be to concern a discrepancy between isoprene models and measurements, not climate models and temperature observations. I'd go so far as to wager he hasn't even bothered to read the paper. Lame but typical. The work sounds useful though and no doubt will go into the pot and help refine GCMs, just not in the way that Lewis so desperately wants.
As an aside, it is really quite adorable how Lewis is using the Register as a platform to run his own pre-COP21 disinformation campaign. And single handedly as well because all of the Register's proper science journalists have reputations to uphold so wouldn't stoop this low.
