The root of every issue that we collectively term “environmental problems” is human overpopulation. It wouldn’t matter if everyone on Earth drove a Hummer and used incandescent light bulbs and dumped raw sewage in their local watershed — if there were only fifteen people on the Earth. But the reverse is also true: if everyone … Read more
A table from the article “Communicating the Science of Climate Change,” by Richard C. J. Somerville and Susan Joy Hassol, from the October 2011 issue of Physics Today, page 48: There’s a lot to ponder in this table. It strikes me as an important document – a compilation of one of humanity’s most tragic miscommunications. … Read more
I read an article in the current issue of Physics Today with interest. It deals with the nature of scientific controversies, as percieved by the public and by specialists in the field in question. The author, Steven Sherwood, compares the origin of the ideas of a heliocentric solar system, general relativity, and human influence on … Read more
Picking up where we left off on Thursday’s post on the relationship between the 2011 Republican presidential hopefuls and science, we examined their statements on climate change. Today, we look at the other information compiled by NPR, their statements on evolution. Michele Bachmann I support intelligent design. What I support is putting all science on … Read more
You may have heard that the Republican party has been embracing non-scientific and anti-scientific positions lately. National Public Radio compiled a bunch of quotations reflecting this trend on their website yesterday. I thought I might take a moment here on the blog to critique their statements (both pros and cons), and then reflect on why, … Read more
Hot on the heels of my discussion of yesterday’s “end is nigh” prophecy, here’s another one, an example that more plausibly wears the cloak of pseudoscience. A cousin sent me a link to this video via Facebook, and asked me what I thought. I sat through it (ten minutes of my life I’ll never get … Read more
Outside a metro station in DC a couple of months ago, I noticed a group of people with signs, pamphlets, and earnest expressions. They were advertising the “good news” that the end of the world was soon: May 21, in fact. They’ve been getting some more attention since, and since May 21 is this coming … Read more
A few items for your perusal… Simon Winchester wrote an article that made a lot of geologists cringe; then he wrote another that dug the hole deeper. If you haven’t been following the conversation on Twitter, then you can play catch up. Some of us geobloggery types are submitting a letter to the Newsweek editor … Read more
A new poll by Gallup suggests that the proportion of the U.S. population concerned about climate change has dropped to an almost record low (51% of the “polled population worrying about climate change a great deal/fair amount”). The data are interesting to look at: (source) I thought I detected a little pattern here with the … Read more
I’ve been reading some books lately about atheism. Though I’ve been a functional atheist for many years, I’ve been paying more attention to it lately in light of religiously-inspired idiocy from around the globe. I’ve become convinced that religious belief does more harm than good, and my sense of incredulity has deepened at how far … Read more
A video, “The Dreaded Stairs,” has been getting some circulation lately on Facebook. It shows what happens when a staircase (beside an escalator) gets a makeover which features piano-style keys which make sounds when they are trod upon. Watch the video if you would like; I’m going to focus on the accompanying blurb, which reads: … Read more
A diagram on “how science works” betrays an “experimentalist” bias. This sets Callan off on a rumination on the much-maligned validity of historical science, and that leads to a discussion of the Big Experiment, which is humanity’s influence on the Earth system.
I just finished reading a book that I should have read fifteen years ago, when I first saw it in the library: Carl Sagan’s The Demon-Haunted World: Science as a Candle in the Dark. Over the past couple of years, I’ve taken to listening to the Skeptic’s Guide to the Universe podcast, thanks to a … Read more
Over the summer, I finished reading an excellent history of creationism called The Creationists, authored by Ronald L. Numbers. Many of my students at Northern Virginia Community College come to my geology classes from a creationist background. Some are true believers, some are looking for the perspective of science. Some are quiet about it, others … Read more
The following letter, signed by 255 members of the National Academy of Science, appears in the current issue of the journal Science. I wholeheartedly concur with the content of this letter, and republish it here in the interest of getting its message out to the world. Please take the next four minutes of your life … Read more
