A Surprising Accord

Michael Mann is a well known scientist for folks following the science behind climate change policies.  He is lauded by people that endorse rigorous government responses to curb carbon dioxide emissions.  He is held in somewhat lower esteem by people that are skeptical on the issue.

I would fall into that latter group, FWIW.

However, I remain committed to giving credit where credit is due.

In 2015, NOAA "updated" their temperature records and insisted that there had been no "pause" in the increasing temperatures of the planet.  Two of the many reasons for my skepticism are the regular fiddling with the temperature records that go on from time to time and the documented pause in global warming that began in 1998.

While there are many legitimate reasons to adjust the recorded temperature data (i.e. change in recording equipment/location, etc.) it seems that there have been other adjustments to the record that are less legitimate.  In this case, the NOAA "update" was timed to coincide with the Paris climate conference.  Such a coincidence inspires the suspicion that this particular adjustment was done to provide a media opportunity in support of additional carbon restrictions.

There have been other examples of "adjustments" that are questionable as well.  For example, there were questionable changes made to 20th century data collected from long term sites in Australia.

As I know someone will misconstrue this, let me reiterate: there are many legitimate reasons for adjusting the temperature record.  And those legitimate adjustments can and will push the recorded data higher.

The pause in global warming is important because it was not predicted by the many models used by scientists to evaluate the impact of carbon dioxide on our environment.  Skeptics, like me, point to that oversight and respectfully suggest that the models may not accurately reflect the actual functioning of the environment.

Do you know who happens to agree with me?  Michael Mann and a host of other scientists that have published a letter in Nature Climate Change.  This summary by Scientific American is also helpful.

Now I think it is fair to say that Mr. Mann still believes that anthropogenic CO2 is a significant problem that is worthy of immediate government action.

My perspective on government action is a bit complex.  I think there are things we could do to reduce CO2 emissions that would benefit humanity even if science inevitably discovers that the climate isn't very susceptible to those emissions.  Things like promoting power via nuclear fission, nuclear fusion, and various biofuels come to mind.  I think there are things that we could do that would devastate humanity such as the various carbon tax proposals.

However, I also believe in giving credit where it is due.  In this case, Mr. Mann participated in countering a flawed process and insisted on doing the hard scientific work to make the models accurately reflect our world.  Getting it right matters.  On that subject, I agree with Michael Mann.
