The Blatant Errors in the SkepticalScience Video “Global Warming over the Last 16 Years”

David Rose’s October 2012 article in the MailOnline generated a multitude of responses around the blogosphere.  The article was titled Global warming stopped 16 years ago, reveals Met Office report quietly released… and here is the chart to prove it.  There have been so many blog posts about the article it’s not practical to list them all.

SkepticalScience—a blog run by advocates of human-induced global warming, not global warming skeptics—attempted to counter the Rose article a number of times.  They included a YouTube video in their January 2013 effort 16 More Years of Global Warming.

The following YouTube video On the SkepticalScience Video “Global Warming over the Last 16 Years” is my reply to it.  It illustrates and discusses the blatant errors contained in the SkepticalScience video. I’ll go into more detail in a follow-up post.  I simply wanted to upload this video in advance of that more-detailed discussion, which will be an update of and expansion on previous posts.

UPDATE:  My apologies to those who are new to this discussion. I tried to limit the time of the video and that meant I couldn’t include a detailed explanation of the mechanisms that cause the natural warming of the oceans.  However, I should have provided links to additional information in the post.  The primary mechanism for the natural warming of the global oceans is El Niño-Southern Oscillation. It is discussed in detail in the following two-part video series titled “The Natural Warming of the Global Oceans”. Links: Part 1 and Part 2.

Also refer to the illustrated essay “The Manmade Global Warming Challenge” (42MB).

    Watched the video. According to you what is causing the net warming during the pacific decadal oscillation. I didn’t see any explanation for the mechanism for that. One would expect that if the ocean were net warming that after each oscillation the temperature would climb during the period when deep stored warm water is able to spread back over the surface. During the storage phase any cooling by upwelling cold water could certainly be masked by a strong enough forcing. You did not propose what that forcing was.

    Brian: Thanks for taking the time to watch the video. Sorry about the limited explanation. I tried to limit the time of the video and that meant I couldn’t include a detailed explanation. However, I should have provided links to additional information in the post. I’ll provide an update.

    First, the PDO is an aftereffect of ENSO, so please put the PDO out of your mind. Second, the mechanism (El Nino-Southern Oscillation or ENSO) is discussed in detail in the following two-part video series.

    Watched the first of the new videos. Sorry, I’m not well versed in this area and did not know that the ENSO and PDO were different things. I actually meant the ENSO in my first comment. I see from the video that the forcing is reduced cloud cover during the La Nina event warming the cool upwelling water and storing it the west pacific. One can see that with longer or more frequent La Ninas there is a natural mechanism to increase forcing built into the system. Like if your home furnace turns on more frequently, and for longer periods then your house will become warmer. The short periods during which that extra heat is accumulated seems like very strong evidence that recent warming has be mostly driven by reduced cloud cover. CO2 concentrations in the air do not change in an on in off fashion that could explain this. Also why would smooth increases in CO2 only raise ocean heat content during the La Nina? CO2 cannot explain the increase. I think we can know CO2 does, all other things equal, to increased temperatures but it must be a minor factor in recent warming.

    Brian, too bad more “climate scientists” aren’t as perceptive as you.

  5. Bob Tisdale says:

    Richard: Too bad more climate scientists don’t examine data and attempt to determine the role of Mother Nature.

  6. Wrote a few tweets, the first mention that you made this video response. Here the 2nd and 3rd:

    Btw, I’m not 100% sure I’m blocked at the site, but at least years ago they refused to accept my comments with facts, so that I had to give up. I wonder when the Skeptical Science disciples understand that truth isn’t accepted. (The problem is of course the power grab ambitions from the environmental movement, driven by a message of moral superiority; thus a comparison with religion is adequate.)

    Very off-topic, but I also tweeted this video and that “prof. Chris Landsea (formerly in IPCC) says that only 1/4 of the warming may be due to CO2”.

  7. Here comments on Skeptical Science, when the site (maybe for the first time) stopped comments from being posted at Youtube:
