Climate Change
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!

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:
gregladen | May 25, 2011People are asking me: Is the recent spate of tornadoes caused by global warming? The usual answer to that question is that you can't answer the question because a tornado is not caused by climate ... it is cause by weather ... and global warming (which is real, and which is cause by humans) is climate change.
However, that is not really the best answer to the question. Ultimately, I want to propose an analogy for how to think about this question, but first, a stab at a good answer, which if modified could probably be improved:
Question: Is Anthropogenic Global Warming the cause of the…
gregladen | March 8, 2011These masses of ice are now contributing more new meltwater to the world's seas than all other melting ice combined.
The Greenland and Antarctic ice sheets are losing mass at an accelerating pace, according to a new NASA-funded satellite study. The findings of the study -- the longest to date of changes in polar ice sheet mass -- suggest these ice sheets are overtaking ice loss from Earth's mountain glaciers and ice caps to become the dominant contributor to global sea level rise, much sooner than model forecasts have predicted.
The nearly 20-year study reveals that in 2006, a year in which…
gregladen | February 27, 2011An inquiry by a federal watchdog agency found no evidence that scientists at the National Oceanic and Atmospheric Administration manipulated climate data to buttress the evidence in support of global warming, officials said on Thursday.
The inquiry, by the Commerce Department's inspector general, focused on e-mail messages between climate scientists that were stolen and circulated on the Internet in late 2009 ...

gregladen | February 16, 2011How do you separate harmless belief in religion or superstition and ... well, harmful belief in religion or superstition? We have been having a bit of a go-round* between some of my regular blog readers, including my Catholic but not anti-Evolution niece whose daughter recently acted in a commercial for the Creation Museum in Kentucky. Sondrah and I respectfully agree to disagree about certain issues, but clearly do agree on the importance of having real science, and not creationism, taught in public schools. That is what a lot of people who think of themselves as religious prefer,…
gregladen | November 13, 2010I am speaking of Representative John Shimkus, R-Ill, and the truly astonishing words he uttered before Congress demonstrated in a video that is constnatly being trolled off Google and YouTube by those who don't want you to see it:
Source and more information here.
If God's Word is infallible, unchanging, and perfect, then dinosaurs did not live in a different era than humans, and not in great antiquity, and what geologists and paleontologists say about the "age of dinosaurs" must be the word of Satan designed by the dark lord of the underworld to confuse us.
If God's Word is infallible,…
gregladen | November 10, 2010You've heard that the Arctic ice cap has shrunk, and that there are sea lanes open in the northern summer that had not been open previously, and on and so forth.
Since the start of the satellite record in 1979, scientists have observed the continued disappearance of older "multiyear" sea ice that survives more than one summer melt season. Some scientists suspected that this loss was due entirely to wind pushing the ice out of the Arctic Basin -- a process that scientists refer to as "export." In this study, Ron Kwok and Glenn Cunningham at NASA's Jet Propulsion Laboratory in Pasadena, Calif…
gregladen | November 9, 2010As global warming progresses, habitats change in their suitability for various life forms. It may be that moose will not be able to live in Minnesota in the future; Of the two resident moose populations, the one that lives in the area more affected by global warming has pretty much died out probably due indirectly to the effects of increased temperature. There are regions of the rockies where entire forests are dead because of temperature changes. And so on.
Imagine a large flat landscape. As one moves north vs. south, average annual temperature changes, as does the number of days of…
gregladen | October 29, 2010Interesting to look back at this now that the Arctic Ice Cap is opening up and disappearing:
A new NASA study shows that the rising frequency and intensity of arctic storms over the last half century, attributed to progressively warmer waters, directly provoked acceleration of the rate of arctic sea ice drift, long considered by scientists as a bellwether of climate change.
NASA researcher Sirpa Hakkinen of Goddard Space Flight Center in Greenbelt, Md., and colleagues from Woods Hole Oceanographic Institution, Woods Hole, Mass., and the Arctic and Antarctic Research Institute, St. Petersburg…
gregladen | October 13, 2010I was under the impression that "Reason" magazine was a libertarian neocon climate denialist rag. I could be wrong, but that's what I thought. I was also under the impression that JREF was pro-science and at this point had gotten beyond the whole "let's remain skeptical about global warming" thaing, especially since Randi stepped in it a while back and accidentally forgot that only paid-off or delusional scientists denied AGW. But now we find the JREF site pushing Reason magaazine in a post on their site.
Someone please help me understand what I'm seeing here.
