This just came in from NBC Last week, Clinton said, "I have been waiting for the administration to make a decision," she said last week in Concord, NH. "I thought I owed them that. I worked in the administration. I started the process that is supposed to lead to a decision. I can't wait too much…

Look at the graph at the top of the post. This is a graph from the now famous Exxon documents that date to 1981, explaining how Exxon scientists were projecting global warming with continued release of the greenhouse gas CO2 into the atmosphere.

Every now and then an animal shows up where it is unexpected. Why just the other day a black bear had to be coaxed out of a tree down by the middle school, a couple of blocks form here. Even though our marshes, woodlands, and small patches of prairie house cougars, coyotes, deer, and all the…

We drove north for two days, to arrive at a place that existed almost entirely for one reason: To facilitate the capture and, often, consumption of wild fish. The folks who run the facility make a living providing shelter, food, boats, fishing tackle, easy access to a fishing license, and they can…

Eating your enemies is a time honored method for winning. It is rarely used by American politicians or their supporters. Here is how you eat your enemy. I'll use a generalized example based on several events during the GOP debates. Moderator: Mr. Trump, you've said 'bla bla bla bla'. Alternate…

Liquid fuel powering internal combustion engines is inherently inefficient. This is because innumerable explosions causing kinetic work to be done also makes piles of heat, and for other reasons. The same amount of energy put into an electric motor and an internal combustion motor produce more…

OK, not really, I just made that up. But it should be! As all the kiddies are going back to school, especially yours if you've got 'em, and you are going to have your first meetings with the teachers (Parent Night, Conferences, etc.) over the next few days, this is a good time to bring your kid's…

The National Snow & Ice Data Center has declared that the Arctic Sea ice extent has reached its annual minimum and is now starting to expand. I was thinking that it was too early to say this, since in past years what looks like a minimum can sometimes be reversed by some additional melting.…

After, not before, you get to the hospital, I always say. But seriously, Robert Martin, the famous primatologist, has an interesting piece in Psychology Today exploring this question. Go read it. I've got a few thoughts spurred by this research I'll list briefly here. First, it seems that wild…

September is when the melt of the Arctic Sea Ice stops, and the re-freeze starts. We are probably not at the minimum yet, but the amount of melting is starting to level off so we can see where we are. The above graphic, made here (go and play with the interactive graph) shows the first ten years…

Someone just asked on Facebook if humans are naturally carnivores. My response: What is a carnivore? Taxon? A certain percentage of meat in the diet? Some, even if just a few, humans living mostly off meat? What? Then, what is “naturally”? Genetically determined and unavoidable? Required because…

I'm on my way to a taping of the Humanist Views with Host Scott Lohman. I do these now and then and have done so since I first moved to Minnesota back when it was still cold here. We'll be talking about science knowledge, and why basic science knowledge is important. We'll also be talking about…
