Michael Mann Vindicated (Again) Over Climategate 961

Posted by Soulskill
from the arguments-that-cannot-be-won dept.
An anonymous reader writes "Michael Mann, a climatologist at Pennsylvania State University, was one of the central figures involved in the 'Climategate' controversy, which saw many private email conversations between researchers posted publicly. Now, an investigation (PDF) by the National Science Foundation has found "no basis to conclude that the emails were evidence of research misconduct or that they pointed to such evidence." Phil Plait points out that other investigations have found similarly that claims of Mann's misconduct took his statements out of context. 'A big claim by the deniers is that researchers were using "tricks" to falsify conclusions about global warming, but the NSF report is pretty clear that's not true. The most damning thing the investigators could muster was that there was "some concern" over the statistical methods used, but that's not scandalous at all; there's always some argument in science over methodology. The vague language of the report there indicates to me this isn't a big deal, or else they would've been specific. The big point is that the data were not faked.'"

        Further, if we're tlaking science we should stop using the term "greenhouse effect". A greenhouse works by stopping convection; its effect on IR radiation actually cools the inside.

        The Earth's climate is mostly convection as well, with IR radiation from the surface a lesser form of surface cooling. As blackbody radiation goes with the forth power of temperature, and the upper atmosphere is pretty cold, it's not obvious why surface-emitted IR warming of the atmopshere would make make difference to surface

        2. Humans produce 100 times as much CO2 per year as volcanic eruptions do. Volcanic eruptions have been shown over and over to usually result in net cooling of the climate from sulfer dioxide emissions. []

        While this is possibly true (and I'm not saying it is or is not), it misses the point. The problem is balance, rate, and source. Without man made sources of CO2 the Earth ecosystem has to deal with naturally occurring CO2. If there are more producers than consumers of CO2, then ecosystems will shift over time to have more consumption of CO2. However man-made sources have increased it within the last 150 years. The rate of CO2 addition is far faster than ecosystems can consume.

      How do we reduce CO2? What will it cost to do it?

      This is a fool's errand. Let's make this learning process more granular. Break it down into separate steps:

      1. Confirm global warming is occuring.
      2. Confirm that global warming is man-made.
      3. Decide how best to counter this effect.

      Given that climate scientists are constantly attacked by political witch hunts [] (and, no, there have been no formal charges of fraud against scientists claiming global warming is fake). The heart of the problem here is that the first two steps should be almost completely scientific endeavors free and devoid of any politics. Yes, the studies cost money but there's money to be had both ways (I would even say that there's more money to be had if your findings absolve polluters of any guilt).

      Once everyone is at step two, we can proceed with the clusterfuck that is world politics. I recognize the core problem is that some politicians cobble it together and go back to step two or -- god forbid it -- step one and then attack those. Instead of recognizing that we've already made ground, we go back and people mire everything up with "extraordinary claims require extraordinary proof." And then the witch hunts begin and we're not making any progress ... meanwhile the polluters are counting their money and protecting that profit margin by lobbying and funding "think tanks" and spreading lies.

      Can we all just scientifically get to step two and then we'll go from there? The climate scientists are the experts. You're not suddenly compelled to rip apart the latest Computer Science study as an armchair computer scientists because you haven't studied it. Why are people suddenly compelled to call climate scientists -- who are basically the same figureheads in academia that computer scientists are -- into question?

In one of the contexts (presentation to the laymen) it was actually presented as one chart. What the conclusions of the "study" didn't mention is that one possible interpretation for discrepancy in the data is not an "error" (as they claimed) but that some of the variables in data collection were not accounted for. He was vindicated of the most brazen accusation. But the emails indicated the frame of mind of the scientists which is consistent with the accusation that they more than willing to overstate the certainty of their conclusions. What exacerbates this overstatement is their claim that peer-review is an adequate method for such fact finding. Peer review is only useful for repeatable experiments. Obviously, whether measurements are not repeatable. So peer review is wholly inadequate for this type of research. Fact finding based on non-repeatable events must be conducted through adversarial review. And that's precisely what they are trying to avoid.
