gregladen | April 6, 2014I just watched a report on ABC news about anti-vaxers causing the current and alarming measles outbreak. It was a reasonable report for MSM though I missed large parts of it because I was multitasking ineffectively. But an idea came to me that would go a long way to manage this problem of anti-vaxers threatening everyone else's health and well being. Lives, even. They are threatening our lives.
Here's the deal. Most public schools have a mealy-mouthed policy that allows people to send their kids to school unvaccinated because they are dumb asses. That's a problem and that should be…

gregladen | April 3, 2014I grew up (and beyond) in the US northeast. There, the weather was pretty good at coming at us from the West, though a nor'easter blowing in from the North East (unsurprisingly) was not uncommon in New England. Although I had studied sea level rise and some Pleistocene climate reconstruction, when I first went to the field in Central Africa I was pretty unschooled in areas of climate and weather. I remember the first several days in the Ituri Forest. I though I knew which way was North, South, East, etc. but then I would get turned around because the big storms -- that came in every single…
gregladen | April 3, 2014The 538 comment system appears to not be working, probably because of my current highly suspicious location, so I figured I'd put my comment here (since I spent a whole minute writing it):
"Long-range forecast models have come to a consensus recently that a minor to moderate El Niño pattern may develop six to nine months from now.
That just isn't true. Forecasts suggest a 50-50 chance of El Nino, but this is hard to predict. There is no consensus that an El Nino will develop among forecasters who are always super cautious about this prediction and there is only a 50-50 chance.
Also, I see…
gregladen | March 31, 2014STFU.
Seriously. For your own good.
Every time you make a move you seem to create your own pile of dog do and step in it. The latest own-goal for those who deny climate science was scored after an unreasonable and obnoxious attack on Professor Lawrence Torcello, of RIT. Details here and here.
Those mentioned above, and others such as the Drudge and Infowars, lied. They lied knowingly, blatantly, obnoxiously. They willfully misconstrued Lawrence Torcello's word and his research in order to make climate scientists look like Hitler. This is not a new tactic and it didn't work before.
And…
gregladen | March 28, 2014I'm going to update this graph every now and then.
There are 12 lines on this graph.
The colorful squiggles up along the top are the first ten years of Arctic Sea ice extent for the period for which we have really good data. So this is 1979 - 1988. There is reason to believe that this is the "normal" sea ice extent track over the year from which we have seen significant deviation over recent decades.
The dark thick line is the average of all of the years from 1979 to 2010. Notice that the first ten years are all above the average except for a few little bits.
The partial line below all…
gregladen | March 27, 2014Salamanders can be a proxyindicator for climate change. Changes in salamanders have been linked to climate changes during ancient times, and in a very recent study, salamanders in the US Appalachians seem to have changed in relation to anthropogenic global warming. In fact, the changes observed in these Appalachian salamanders is quite large, very rapid, and thus, alarming. I’m going to describe this study in some detail, and as a bonus for sticking with me on this, I’ll throw in some entertaining Climate Science Denialism near the end. As an additional bonus prize, you’ll get a nice new…
gregladen | March 27, 2014Michael Mann, Byron Steinman, and Sonya Miller have just put out a new paper on climate change which addresses a number of key concerns. The paper is called “On Forced Temperature Changes, Internal Variability and the AMO.” Here’s the abstract:
We estimate the low-frequency internal variability of Northern Hemisphere (NH) mean temperature using observed temperature variations, which include both forced and internal variability components, and several alternative model simulations of the (natural + anthropogenic) forced component alone. We then generate an ensemble of alternative historical…
gregladen | March 26, 2014We know know what the famous announcement by the European Southern Observatory is. They found an asteroid with ring! Two of them!
...the remote asteroid Chariklo is surrounded by two dense and narrow rings.
Telescopes at seven locations in South America, including the 1.54-metre Danish and TRAPPIST telescopes at ESO’s La Silla Observatory in Chile were used to make this surprise discovery in the outer Solar System.
This unique finding has sparked much interest and debate since it is the smallest object by far to have rings and only the fifth body in the Solar System — after the much larger…
gregladen | March 26, 2014Above is the nifty interactive graphic from the National Snow and Ice Data Center showing sea ice extent in the Arctic for the current year (the lower squiggle). This year's squiggle looks like a peak, and it is possible that Arctic Sea ice extent is now on the decline. Minimum extent is typically reached in September.
The other squiggles are all the years since 1979 that seem to have had peaks later in the year than this year's apparent peak of a couple of days ago. Those years are 1992, 1997, 1999, and 2010. In other words, for the available data set, four out of 34 years, or just over…
gregladen | March 26, 2014This is a followup on Are the climate science deniers criminals?, which explored recent work by Lawrence Torcello, a philosopher at Rochester Institute of Technology. (See: Is Organised Climate Science Denial Criminally Negligent?)
Professor Torcello's point was made in part by reference to the tragic events at L'Aquila, Italy, where a screw up mainly by non-scientist government official seems to have resulted in unnecessary deaths due to an earthquake. Torcello notes:
If those with a financial or political interest in inaction had funded an organised campaign to discredit the consensus…
gregladen | March 26, 2014Trigger warning: Explicit video of a homeless man being executed by the cops.
I strongly recommend that you don't call the police. If you do, because for some reason you have to, get the hell out of there before they arrive. Why? Because our Post-9/11 first responder philosophy is not the first responder philosophy you grew up with. First responders have one primary directive: Protect themselves, at all costs. Your safety is the cost. For firefighters and the like this means running the other way when there is danger, because of 9/11. Recently, a New York City fire chief was quoted as…
gregladen | March 26, 2014From meteorologist Paul Douglas:
Published on Mar 14, 2014
Weather seems to be staling. Look into how the speed of the jet stream causes this "stuck in a rut" weather pattern. Meteorologist Paul Douglas also takes a look back as to how this winter compares to years past. Checking out extreme drought conditions, snow cover and cooler temperatures overall. This did not only impact the U.S. but other areas of the world. England experienced their wettest winter yet!
gregladen | March 25, 2014Today, Wednesday, an immense storm will move into the Canadian Maritimes after grazing the US East Coast. In the US the storm may severely affect Cape Cod with many inches of snow and hurricane force winds. At sea, in the northern Gulf of Maine and points north, there is a severe risk to boats with very high waves and very severe winds. Halifax could get a foot or two of snow and there will be high coastal waves and strong winds.
This is a rare storm, but of the class of storms that seems to have become more common as the global system of air currents shifts under conditions of global…
gregladen | March 25, 2014UPDATED: THIS is the discovery.
The European Southern Observatory will make an announcement tomorrow (or later today depending on where you read this, but Wednesday) about an amazing new discovery they made in outer space.
I'm not going to tell you what they found because it is top top secret. But it is very interesting and cool. What I can show you is part of the hilarious twitter feed called #ESOrumors that sprung up today in the Astronomy community.
That's just a sampling.
Stay tuned!
gregladen | March 25, 2014Dean Snow was one of my two advisors in undergraduate school. I have fond memories of all six months of college. But that's another story. Anyway, several years ago, Dean got wind of the research showing that humans exhibit sexual dimorphism in the ratios of the middle digits of the hand. It is believed that this is accounted for by differential rates of bone growth during early development that happen to be different, on average, between males and females. There is probably not an adaptive explanation for this. Rather, at some important developmental stage there is an endocrine effect…
gregladen | March 25, 2014After 16 minutes, Michael Mann on climate change, climate sensitivity, etc.
Why does Joan of Arc Being look so worried? The fire hasn't even touched her!
Mann uses the analogy of a person jumping (or being thrown?) off a tall building, and as he passes the third floor notes that everything is fine. Another analogy that might be helpful is being burned at the stake. After they tie you to the stake and pile up the wood, you're fine. Then they light the wood on fire and you're still fine. For a while.
The climate sensitivity graph above is from here.
gregladen | March 25, 2014It is very hard for me to view the world without my Anthropological glasses, since I’ve been one kind of Anthropologist or another since I was 13 years old. Thinking about climate science deniers, I realized what makes them annoying to me. Let me tell you what I mean.
The ongoing conversation at an archaeological site.
When Archaeologists (a kind of Anthropologist, in the tradition I was trained in) dig a site, they are constantly learning about what is under ground at that location, and throughout the process develop a model of what it all means. As an aside I should mention that…
