Sokal and Mooney Op-Ed in LA Times

February 4, 2007

See Chris Mooney’s blog, The Intersection, for more introduction to this editorial that he and Alan Sokal co-authored in today’s LA Times. It’s titled Can Washington get smart about science?, and is a nice little piece of writing.

What I like is that Sokal has been known to criticize liberals and Mooney has a book about conservatives in government and their subversion of science. I like to see people team up like this and cut through the partisan crap. It’s all too easy for people to stay on “their side”, whatever that means. The partisan brain is a funny thing. People with strong partisan tendencies tend to automatically believe, agree, disbelieve, disagree with statements that have yet to be checked for its truthiness.

Sometimes when I stroll about the blogosphere I get severely turned off by ultra-partisan “liberals” spouting complete nonsense. Conservatives do the same, of course….I guess I don’t find myself strolling about their internet neighborhoods though.

Anyhow….read Chris and Alan’s article, it’s good.

Where On (Google)Earth #4?

February 4, 2007

The only clue i’m gonna give for this one is that the boundary between shallow water (light blue) and deep water (dark blue) is very sharp.

Good luck!

Commentary on commentary

February 3, 2007

Keep in mind, this is only one example of this kind of idiocy. Unfortunately, a lot of people get their “information” (opinion) from people like this. For those of you who don’t know, Neil Boortz is a Rush Limbaugh-wannabe (sad). Apparently he and another author have written a very thoughtful book about tax reform that I hear good things about. I haven’t read it yet, so I can’t comment on that but that’s not what this is about. This is about someone with a megaphone and a lot of loyal listeners (choir members) spouting stupidity about the recent IPCC report.

I neither have the time nor energy to deconstruct all of this…here’s some of my favorite tidbits from his editorial titled “Why I Am Skeptical About Man-Made Global Warming

A 21-page report from something called the “Intergovernmental Panel On Climate Change” has been released today…in Paris, no less…and as expected, it’s predictions are dire.

Sweet…right off the bat, we get some anti-French sentiment. Always a crowd-pleaser.

But really, it makes sense that the global warming crowd would come to this conclusion. After all, global warming is a religion. The anti-capitalist enviro-nazis don’t ever want the problem to be solved. After all, if global warming were to be solved tomorrow, what would they blame the United States for? They’d have to find some other reason.

The underlying motivation for being skeptical about this report is revealed in this introductory section of the editorial. It’s not about science at all….it’s about the anit-capitalist enviro-nazis…let’s call them the ACENs. The ACENs have plotting to take over the world since the first Earth Day I think. This is key to understanding this point of view. By connecting “anti-capitalist” directly to the prefix “enviro” and then throwing in the evil noun “nazi” the stage is set.

He then goes into a bunch of bullet points that are weak, unsubstantiated, and have been torn down numerous times. But, remember, it doesn’t matter because the connection between being “enviro”, whatever that means, and anti-American has already been established. Let’s look at a few of the points that actually mention climate science in some way or form (as fun as it is, we’ll move away from the ACEN theories).

Because the sun is warmer .. and all of these scientists don’t seem to be willing to credit a warmer sun with any of the blame for global warming.

Hmmm….reference? Of course, an editorialist can’t be bothered with citing. This claim, however, does not fall under opinion. To say something like this requires some backing. But, I will say this…at least he doesn’t discredit the actual warming. There aren’t many of those left. It’s mostly about cause now.

It wasn’t all that long ago that these very same scientists were warning us about “global cooling” and another approaching ice age?

The very same scientists. Who are they? He, of course, doesn’t provide a list. He wants his followers to picture a small group that meet in undergound lairs (sensu Dr. Evil) plotting to take over the world. Here in reality, we know that this report is the summation of hundreds of scientists from around the world and across disciplines.

How much has the earth warmed up in the last 100 years? One degree. Now that’s frightening.

What an idiot. When the global average temperature was 5-6 degrees colder than now there was an ice sheet a mile thick sitting over my hometown in New York state

Because that famous “hockey stick” graph that purports to show a sudden warming of the earth in the last few decades is a fraud. It ignored previous warming periods … left them off the graph altogether.

Please demonstrate the errors in this. Oh wait….all you have to do is assert that, I forgot. See this summary of the hockey stick graph debate.

Because global warming “activists” and scientists seek to punish those who have different viewpoints. If you are sure of your science you have no need to shout down or seek to punish those who disagree.

Seek to punish. Seek to punish?

What happened to the Medieval Warm Period? In 1996 the United Nations Intergovernmental Panel on Climate Change issued a chart showing climatic change over a period of 1000 years. This graph showed a Medieval warming period in which global temperatures were higher than they are today. In 2001 the IPCC issued another 1000 year graph in which the Medieval warming period was missing. Why?

Oooh…juicy. Conspiracy. More here.

There are about 160,000 glaciers around the world. Most have never been visited or measured by man. The great majority of these glaciers are growing, not melting.

The great majority….what is that 70%? Reference? Of course not.

Rising sea levels? The sea levels have been rising since the last ice age ended. That was 12,000 years ago. Estimates are that in that time the sea level has risen by over 300 feet. The rise in our sea levels has been going on long before man started creating anything but natural CO2 emissions.

One of my favorite things people like this do is confuse the issue by constantly bringing up facts about the Earth’s climatic fluctuations. What about rate of rise instead of magnitude, Mr. Boortz? If you look at the sea-level curves for the last 12,000 years you see the rate of rise slow until about 5,000-6,000 years ago. Since then the rate of rise is very small, hence we’ve been at a “stillstand” in sea level (see Lambeck & Chappel, 2001).

During the last 20 years — a period of the highest carbon dioxide levels — global temperatures have actually decreased. That’s right … decreased.

Another assertion with no reference.

Why are global warming proponents insisting that the matter is settled and that no further scientific research is needed? Why are they afraid of additional information?

I definitely want to know what scientist ever said they didn’t want more data…..that’s all we want! We can’t get enough of it…give me a break.

There’s a lot more of this kind of stuff in that particular editorial as well as out there on the airwaves, TV, and internet. The “great majority” of it is repetition of the same assertions that are, at best misconstrued and, at worst downright false. The fact that these assertions are seldom referenced by people like Boortz is because he knows by citing a particular study he is inviting rigorous scientific critique of his information (which has been done already). By doing this in an editorial fashion he doesn’t have to reference and he continue preaching about the real message: that the anti-capitalist enviro-nazis (ACENs) are plotting to take over the world.

Day in the Life

February 2, 2007

Lab Lemming and Highly Allochthonous decided to answer the question: “What do scientists actually do?”.

See what they do on a typical day here and here.

For me, not sure this is a typical day…it’s Friday and I just finished a draft of a long paper 2 days ago and gave to advisor. But here goes anyway…

8:15-8:50: train ride into office
8:50-9:25: check email and make blog post about French turbidites
9:25-10:00: chat with colleague on phone who just started a tenure-track position this month, discuss possible future collaborations
10:00-11:15: update spreadsheet database and associated plots with new radiocarbon ages for Holocene sediments offshore southern CA; get excited about how well-constrained this basin is temporally
11:15-11:45: chat with colleague on phone about the above; directions to go for writing it up
11:45-12:20: lunch
12:20-2:00: research possible job opening; start application process
2:00-2:15: get information together for rock samples I need to start processing next week
2:15-2:45: look for said rock samples in inefficient and messy storage area in the attic of building i’m in
2:45-2:50: have a little freak out moment when can’t find rock samples (they are all the way from South America!)
2:50: remember I already put them aside right under my desk…phew
2:50-3:40: search for paper online that i’ve been meaning to look at; found it and read abstract, intro, and looked at figures
3:40-now: write this blog post
after now-later: go home and go out to dinner with girlfriend and another friend in San Francisco

Pretty easy-going day all in all

Friday Field Foto(s) #10: Turbidites in the French Alps

February 2, 2007


Instead of one photo this week, i’m gonna show a series of photos from a trip I took to southeastern France last June. Most of my research is involved with characterizing and understanding the deposits of turbidity currents, or turbidites. Essentially, picture an underwater ‘avalanche’ of sand and mud. The sediment travels down a slope into the deep water in fast-moving turbulent flows. Additionally, this very outcrop is where, in the late 1950s Arnold Bouma developed what has come to be known as the ‘Bouma sequence’.

The photo above and to the right is a succession of alternating sandstone beds and mudstone beds (note trees for scale).

A road snaked its way up this mountain so we were able to look the rocks in more detail in the well-exposed roadcuts.

This photo shows the character of bedding at a scale of a few meters. The thicker sand beds are typically a little coarser-grained and tend to be more resistant and stick out of the cliff. The finer-grained material is commonly in thinner beds and more recessive.

Statistics of bed thickness patterns have been done for many years on turbidites. The variability is so great from place to place that there doesn’t seem to be a very systematic pattern. Some workers have documented some interesting relationships (Talling, 2001 has a good summary of this).

A lot of turbidite sequences include intervals of chaotically deformed material. It may look like good ol’ tectonic deformation but it is the result of slumping and sliding of material on the sea floor. In steeper areas of the slope leading to the deep sea, material that was deposited may sluff
off as submarine landslides. The blocks can stay
relatively intact in many cases.


Here’s a larger-scale view of a famous outcrop called Chalufy (note trees for scale). This face is cool because you can see the sand-rich bodies pinching out into the blue-gray fine-grained rock. If you notice there are two distinct sand intervals that successively pinch out as wedge shapes from left to right.

This represents the edge of the deep-marine basin. A series of sand-laden turbidity currents came down the slope and incrementally deposited material that started filling in this hole. This kind of complex stratigraphy is more the rule than the exception. These are not simple layers. These flows both create and respond to sea-floor morphology with channels, levees, fans…you name it. The challenge is to take a preserved ancient succession like this and interpret the processes and morphology that existed on the sea floor. From there we build up and start to understand how the basin filled, what controlled the patterns, and relate it to the tectonic evolution.

I’ll be posting a bunch of web resources for turbidite research soon….still working on that.

IPCC report

February 2, 2007


This is clearly one the biggest science news stories of the day/week/month/year/decade and there’s tons o’ hype…so i’m not going to do a lot of commenting until I have a little time to look at it. Not that i’m any sort of authority…but I like to go over things at least a little bit before trying to summarize and/or synthesize.

The actual Intergovernmental Project on Climate Change (IPCC) report can be obtained here today (2/2/07). The last report was in 2001…this is a significant body of work involving hundreds of scientists from around the world. The review process to decide on the final wording was quite rigorous.

The one thing I’d like to remind people is that this, the first report in a series, is the scientific background. The full report about policy is forthcoming (although there is a short summary of that too). It is extremely important to separate these. Yes, of course they are linked…I don’t deny that. But, we should emphasize the objective information at this point.

There will be tons of noise about this report from every direction…..don’t read mainstream media summaries that try to present “both sides”…and don’t read your favorite op-ed columnist’s pre-emptive commentary. Just read the dang report!

If you got to the end of this post and are lazy…here’s another link to the IPCC website to download the report. Do it.

RealClimate, as usual, has a great post and good discussion going here.

Infant Ocean Basin

February 1, 2007


This is great. The quality and amount of data we are collecting these days regarding the movements of the tectonic plates is fantastic. This article in Science Daily talks about a study looking the East African Rift Valley….a proto-mid-ocean ridge.

The most dramatic event came in September 2005, when hundreds of deep crevices appeared within a few weeks, and parts of the ground shifted eight metres, almost overnight. More than two billion cubic metres of rising molten rock — magma — had seeped into a crack between the African and Arabian tectonic plates, forcing them further apart.

These researchers are going to sample this new rock. Because this process typically occurs at mid-ocean ridges, it is inherently challenging to take samples. The East African rift is in a very early stage of developing into an ocean spreading center. Once the relatively thin and dense oceanic crust begins to form, the basin will eventually fill with the ocean to create a narrow seaway.

The importance of the Hubble telescope

January 31, 2007

When put into service in 1990, the Hubble space telescope was supposed to last about 15 years. Thanks to servicing via spacewalks, it is still going pretty well. Unfortuantely, one of the cameras onboard has stopped working. The ACS (advanced camera for surveys) can detect light from the ultraviolet to the near-infrared end of the spectrum and has been invaluable for astronomers since it was installed in 2002.

“Technically speaking, it is more risk. Is it worth taking that risk? I would say yes. If I were the administrator, I would go save Hubble. I can’t even begin to tell you all the technological advances Hubble has given us. More importantly, think what we can gain in its future,” retired shuttle Cmdr. Jim Wetherbee says.

The images and information that the Hubble telescope has provided has led to significant progress in understanding our universe…they likely would not have happened by this point without it. It seems every couple of years, the telescope faces challenges, whether it be breaking down or the threat of losing funding. Let’s hope NASA keeps servicing Hubble until the next generation space telescope is put into place.

Woman (with iPod) in the Landscape

January 29, 2007


My very first post on this blog was about the famous “face on Mars” image. Here’s an image from Earth that resembles the profile view of a woman. The shading under the chin and on neck is fantastic.

Put these coordinates into GoogleEarth (or GoogleMaps w/ satellite turned on):
50° 0’38.20″N 110° 6’48.32″W

This is in eastern Alberta, Canada.
Pretty cool, eh?

No, I don’t look at GoogleEarth all the time…I found this here while browsing for science news.
