Global Warming
gregladen | November 2, 2011You've heard about "ClimateGate." ClimateGate was a very successful but illegal campaign by anti-science to discredit climate science and climate scientists. Rest assured, the climate science is fine and the climate scientists are just trying to do their jobs, and doing quite well at that. Nonetheless, a combination of inaccurate representation of the contents of various emails written between climate scientists and what amounts to unethical treatment of climate science by the press resulted in a shift among the general populous in the US from about half of the people thinking that Global…

gregladen | October 20, 2011Urban areas can be warmer than surrounding non-urban areas because there is a lot of combustion, pavement and other structure can collect solar heat and retain it for a while, and other factors. It is not uncommon to look at a weather map where conditions for precipitation are marginal, and everywhere but the urban zone, or only the urban zone and nothing else, is showing a weather phenomenon. Because people and airports (where weather is very important) are located in or very near urban areas, it stands to reason that a lot of the data used to estimate global temperatures would be affected…

Fool Me Twice
Fool Me Twice: Fighting the Assault on Science in America" was officially released last night in Minneapolis with appropriate fanfare and celebration. Everyone who gets to know Shawn likes him from the start and quickly learns to respect him and eventually hold him with a certain amount of well-earned awe, and like any book, we've all seen this one coming for quite some time. (I have an old pre-release copy in which every page is "00" but, surprisingly, the front cover is just like the final form.)
Shawn gave a talk at the release party, but since he is held in such high…
gregladen | October 13, 2011...I'd like to talk about an observation I made while writing for a now defunct monthly rag about global warming back in the early 1990s, and have always wanted to pursue formally, as a research project. Since I've not gotten to it yet, I thought it might be fun to outline the idea more informally, to give you, literally, a sketch or two that makes the point....

gregladen | October 10, 2011My first job as an archaeologist in Boston (having moved there from New York) had to do with Deer Island, the northern of two islands that separate Boston's Inner and Outer Harbors. The actual archaeology was uninteresting but the historical research was fascinating. Among the things I learned is that Boston's Inner Harbor regularly froze over. It no longer does. When the Continental Army placed the British in Boston under Siege at the beginning of the Revolution, the idea of holding off an assault until the harbor froze over was routine. No one expected the harbor to not freeze over.…
gregladen | September 19, 2011In order to do good climate science, you have to understand and control for the sources of variation in the system. In any system that involvs metric change over time, there are four sources of variation:
1) Measurement or observational error (goofs, inaccuracies, bad calibration). The speed was 23 feet per second but the instrument read 22.5 or the observer wrote down 32 by accident, etc.
2) Internal (secular, natural) variation. If A causes changes in B over time, variation in B that would have happened anyway don't count in understanding the A-B link.
3) Causal relationship (causal…
gregladen | September 19, 2011I want to say a word about what a proxyindicator is. And isn't.
I noticed that the term is not in some, perhaps many, dictionaries, so I guess this leaves me free to do what I want with it! But wait, the term "proxy" is of course in the dictionary. It is an ancient short version of the word "procuracy" which is the authority to act for another. Thus, a proxy vote. Proxyindicator (or proxy indicator) is a term widely used in climate science though it is used in many other fields as well to refer to a measurement that is indirect, or more accurately, that stands in for the direct measurement…
gregladen | September 6, 2011You all know about the latest dustups and new research related to climate change, including the resignation of the Editor-in-Chief of a major journal as well as some new papers about global warming. There has been so much activity over recent days that I thought a new link farm would be a good thing. So, here it is. Please let me know if I've missed anything!

On the Misdiagnosis of Surface Temperature Feedbacks from Variations in Earth's Radiant Energy Balance

Opinion: The damaging impact of Roy Spencer's science
In his bid to cast doubts on the seriousness of…
gregladen | September 6, 2011The question of whether clouds are the cause of global warming has been settled:
No, they are not.
The question was raised in July in a paper by Spencer and Braswell, published in the Peer Reviewed Journal Remote Sensing called "On the Misdiagnosis of Surface Temperature Feedbacks from Variations in Earth's Radiant Energy Balance." (See this.) Spencer and Braswell's paper claimed that the Earth's temperature was not really rising due to fossil carbon in the form of CO2 being pushed into atmosphere. Rather, they said, any variation we see in global temperature is a result of natural…
gregladen | September 4, 2011On the face of it, it is impossible. Cosmic rays vary over time, and climate varies over time, and the two variations do not correspond. Global temperature has been going up over the last century, in correspondence with increased of atmospheric CO2, and this makes sense because the physics says that CO2 is a greenhouse gas, and this whole global warming thing is a greenhouse effect. Bringing cosmic rays into the situation seems both unnecessary and difficult to do.
But it turns out that there is a cosmic ray - climate connection which is interesting if it turns out to be true. But this…
gregladen | September 2, 2011There has been a major dust-up in the climate denialist world. A study published in late July made false claims and was methodologically flawed, but still managed to get published in a peer reviewed journal. The Editor-in-Chief of that journal has resigned to symbolically take responsibility for the journal's egregious error of publishing what is essentially a fake scientific paper, and to "protest against how the authors [and others] have much exaggerated the paper's conclusions" taking to task the University of Alabama's press office, Forbes, Fox News and others.
Let me break it down for…
gregladen | August 22, 2011The Inspector General of the National Science foundation has completed an investigation into falsifying research data, concealing or deleting emails or other data, misusing privileged information, and seriously deviating form accepted practices in relation to climate change research by climate scientist Michael Mann. This investigation, just completed, confirms what has been determined by other previous investigations:
An Investigatory Committee of faculty members with impeccable credentials has unanimously "determined that Dr. Michael E. Mann did not engage in, nor did he participate in,…
gregladen | July 29, 2011Sunday's radio show is going to be a very special treat for all of us. Mike Haubrich and I are going to be speaking with Kevin Zelnio and John Abraham about climate change, global warming, and science vs. denialism.
John Abraham is an expert on Heat Transfer and Fluid Mechanics and stirred up a bit of trouble (in a good way) when he responded to a presentation made by AGW Denialist Chrisopher Monckton at one of our local TRC's1, Bethel University. Kevin Zelnio is a former Sbling, a science journalist, and member of the blogging teams at Scientific American Blogs and Deep Sea News. He has…
gregladen | July 29, 2011According to a newly published paper in the journal "Remote Sensing" the Earth's atmosphere releases into space more heat than climate scientists had previously estimated in a way that effectively removes concern about fossil CO2 being released into the atmosphere.
The reason scientists have this wrong, according to the article's authors, Roy Spencer and William Braswell, is that climate scientists use a fundamentally flawed model of atmospheric heat dynamics and radiation of heat from the surface of the climate system into space. The senior author, Spencer, has previously argued that…
gregladen | July 26, 2011Somewhere around 1990 I wrote an article for a monthly paper on global warming. My intention was to explain the idea behind it (the greenhouse phenomenon) and to make clear the distinction between depletion of the ozone layer and greenhouse effects (the two were getting confused on a regular basis in those days). The reason I mention this is that there was virtually nothing in that article that would not pertain today, and other than the addition of piles and piles of data, there has been almost no change in the science of greenhouse effects that has occurred since then. And by that, I…
gregladen | July 11, 2011I woke up this morning and the world was slightly different than it was the night before. Well, it probably always is a little different each day, but there are certain times when you notice this. I'm not talking about the bits of siding, roofing, and trees scattered about the landscape because of the very severe thunderstorm we had last night, although I suppose this is indirectly related.
If you are not a Minnesotan this will take some explanation:
Don Shelby newscaster, was the Walter Cronkite of the Twin Cities. Stately in appearance, white-haired (since birth, presumably), deep…
gregladen | June 28, 2011And what do we do about it?
Global warming is for real, and it is important. Just as important is the fact that global warming is largely anthropogenic. Global warming is important because conditions for life on the planet are changing due to warming as well as other changes caused by the release of fossil carbon into the atmosphere, in ways that will have, on balance, negative impacts; That it is anthropogenic is important because this means we have identified a cause of an important negative effect and thus could potentially curtail it. The anthropogenic nature of global warming is also…
gregladen | June 9, 2011There is no chance that there is any connection between the release of fossil carbon into the atmosphere, no chance, for instance that severe weather is increased because of global warming. Don't give it a second thought. The following video proves that you have nothing to worry about:
