gregladen | August 3, 2013I think there is a belief that pipelines are safer than trucks,trains, or boats for shipping liquid hydrocarbon fuels. That may actually be true. I don't know what would happen if we stopped all the pipelines and switched to vehicles. But the idea that pipelines are safe is absurd and it is time people started to realize this.
The Center for Biological Diversity has posted an interesting analysis by Richard Stover, which we can see in the form of a video.
This time-lapse video shows pipeline incidents from 1986 to 2013, relying on publicly available data from the federal Pipeline and…
dr. dolittle | August 2, 2013I just watched a neat video describing how animals adapt to their environments to increase survival:
gregladen | August 1, 2013Emily S Cassidy, Paul C West, James S Gerber and Jonathan A Foley, from the University of Minnesota Institute on the Environment, have produced a very important study for IOP Science Environmental Research Letters. (This is OpenAccess so you can access it openly!) You know Emily as one of the participants in our CONvergence panel on food last July. The research Emily and her colleagues do is some of the most important work being done right now, because it is about the food supply.
The bottom line is this: When we look at our food supply, we find that a large amount of what is grown in…
jhalper | July 6, 2013Right above the tree tops -- where most people might think there is just air -- Prof. Dan Yakir sees a distinctive atmospheric layer in which all sorts of complex exchanges are taking place. CO2, of course, is one of the important ones, and we still don’t understand all of the ins and outs of its flux through the forest, soil and atmosphere. Moisture, heat (and by extension light) and oxygen all cycle through the interface between the forest canopy and the lower atmosphere, as do a number of volatile organic compounds (VOCs) released by many trees. These compounds may contribute to the…
gregladen | June 27, 2013Here, David Letterman interviews the man who spent two years in prison for trying to sand in the way of the Bush administration's attempt to sell off your future.
More here.
esiegel | June 14, 2013"One of my favorite philosophical tenets is that people will agree with you only if they already agree with you. You do not change people's minds." -Frank Zappa
One of the most difficult things to talk about, for any self-respecting scientist, is politics. Like all of you, I have my preferences, my opinions, and my vision for what a better world would look like. I'm also well aware that if I talked about all of them, there probably wouldn't be a single one of you out there who agreed with everything I had to say.

pharyngula | May 24, 2013Molluscs have amazing super-powers.
But you know what? So do humans. We air-breathing terrestrial bipeds are able to enter strange alien worlds and return with a digital record of the events that even the lubbers among us can appreciate.
esiegel | May 11, 2013"But I'll tell you what hermits realize. If you go off into a far, far forest and get very quiet, you'll come to understand that you're connected with everything." -Alan Watts
As we move farther away from the equinox and towards the solstice, my part of the world is seeing not only more daylight, but also more sunshine, warmer temperatures, and -- at least today -- some glorious days to be out in nature. This weekend, have a listen to Vishwa Mohan Bhatt, Ronu Majumdar, Sabir Khan & Tarun Bhattacharya's interpretive nature song,
Flame of the Forest,
while I share with you my list of the…
esiegel | May 10, 2013"As seismologists gained more experience from earthquake records, it became obvious that the problem could not be reduced to a single peak acceleration. In fact, a full frequency of vibrations occurs." -Charles Francis Richter
You've all been around long enough to be familiar with the severe damage that earthquakes can cause, rattling and cracking the ground, shaking down buildings, and creating catastrophic tsunamis tidal waves. In short, the largest ones that occur in the wrong places will cause billions of dollars worth of damage and will kill thousands of people.

jdupuis | April 29, 2013What kind of place has Canada become?
The kind of place that closes world-class research facilities in the arctic and in lake country. (Thanks, Ontario!)
The kind of place where the government actively muzzles it's own scientists and librarians, the scientists for wanting to share their research and librarians who want to talk about the importance of preserving our heritage, scientific and cultural.
The kind of place where Environment Canada would take their own name off their weather service website. Really? Yeah, really.
The kind of place where the Federal Government slashes its own role…
jdupuis | April 28, 2013hardly ever does The Globe and Mail books section every Saturday feature more than one, maybe two, books that I'm interested in. They're pretty heavy on the Canlit side, with a heavy helping of the kind of public affairs books that don't really do it for me. The mystery roundup feature is usually my best bet. Well this week there were three -- count'em three -- books that really piqued my interest. And a pretty diverse bunch too, one physics, one horror fiction and another environmental non-fiction featuring the kind of intersection between food, science and policy that I find so interesting…
pharyngula | April 8, 2013This is a very special bird from Arkansas that will become much more common with more oil pipelines running through the middle of the country. Won't it be great to be able to readily make an entry in your birding book, soon enough?
pharyngula | April 1, 2013You know those deep icy fields of methane hydrates Japan wants to tap for natural gas? (One of the worst ideas ever, by the way.) They're inhabited, by polychaetes like Hesiocaeca methanicola.
(via NatGeo, which is a bit too uncritical of the idea for my taste.)
jdupuis | March 22, 2013You would think that such apple pie issues as public science, basic research and the free and open exchange of scientific information would be hard to disagree with. You would think that a resolution in the Canadian parliament would to such effect would meet with resounding support, resulting in a unanimous vote, the room resounding with shouted Yays.
You would think that anyone who would vote nay to such a resolution would be a virtual pariah in an open democratic society, a society that values an informed citizenry and evidence-based decision making.
Apparently you would be wrong.…
pharyngula | February 26, 2013I just got back from this evening's Cafe Scientifique — where were you guys? — and I got to see lots of pretty pictures of halos and sundogs and light pillars. One of the nice things about living in Morris is that we actually get a lot of that weird atmospheric phenomena here, because we have lots of the raw material for them here: ice crystals. Vast drifting clouds of hexagonal crystals, flat and columnar, of various proportions, floating in the sky at various orientations to both refract and reflect light into our eyes.
I won't go into all the details, since you weren't there. And since…
pgleick | February 8, 2013Welcome to the first post in my new National Geographic ScienceBlogs column “Significant Figures.” I look forward to sharing my thoughts with you on a wide range of environmental science-related issues, data, and people, and to a productive and constructive interaction.
My background? I’m an environmental scientist by training and inclination, with experience in engineering, hydrology, climatology, and interdisciplinary analysis. My research and writing have, for over thirty years, focused on water resources, climate dynamics and change, energy, risk assessment, and the synthesis and…
pharyngula | February 7, 2013It's always gratifying to see a scientific organization step up and use their collective expertise to make a clear statement on a political and economic issue. The Society for Integrative and Comparative Biology (SICB) has published an open letter to President Obama rejecting the Keystone XL pipeline. The pipeline is a ghastly stopgap that hinders the promotion of better, cleaner alternative energy sources by encouraging ever more desperate and destructive efforts to harvest marginal energy sources…efforts to keep us on our petroleum addiction until the last drop of oil is wrung out of the…
cwhyte | February 1, 2013Inspired by the internet comic “The Up-Goer Five”, which used only the 1,000 most commonly used words to describe the Saturn V Rocket, scientists across the internet are attempting to describe their work using the just this small set of words. And it’s tough! But one of Brookhaven’s atmospheric scientists was up to the challenge. Alistair Rogers, who works in our Environmental Sciences Department, gives it a go:
Understanding change at the top of the world so we’ll know what is going to happen later
When we drive cars and warm our homes we give out bad stuff that ends up in the air. The bad…
esiegel | January 30, 2013"Concentrate all your thoughts upon the work at hand. The sun's rays do not burn until brought to a focus." -Alexander Graham Bell
Imagine a beautiful, clear day. The Sun is shining, the skies are clear, and you couldn't ask for a nicer day.

All of a sudden, the Sun itself appears to brighten, just for a brief amount of time, like it released an extra burst of energy. That night, some 17 hours later, the most spectacular auroral display ever brightens the night in a way you never imagined.
