What is scientific consensus?

A group of scientists attending a major conference get together in a bar. They talk, but they agree on nothing because they are critical academics. The server comes along to take the beer order and says, “I noticed you all are constantly arguing. What are you arguing about?” “Sensitivity,” one of them says. “It is…

I have a few partly formed, preliminary thoughts about some people’s reaction to Baltimore (originally posted on my friend Miles Kurland’s page as a comment, then on my facebook page, edited.) What I’m mainly reacting to is the constant drone of people saying that rioting and anti-state violence in Baltimore is fully 100% wrong and…

Will 2015 be warmer than 2014?

That is a good question, and difficult to answer. If it turns out to be, it will be the warmest calendar year in the instrumental record, which goes back into the 19th century. Regardless of what El Nino (ENSO) does, 2015 will be a warm year. Why? Because everything is warm and getting warmer and…

The funniest thing ever

Just so you know. This is not something where you watch the first minute and get it and go “oh that’s funny” or not and them move on. The plot is complex you must watch it until the very very end or don’t bother. Just sayin’ this because people seem to not do that a…

Remember the last Olympics, during the parade, where instead of seeing the athletes march along grouped by country, we saw unidentifiable people who were all either taking selfies or grabbing videos of everything going on around them, but we couldn’t tell who they were because their cell phones were totally covering their faces? These days…

It is like finding a leak in your roof. I remember once up at the cabin, noticing that my waders were full of water and pointing this out to my wife. “You’re supposed to hang the waders upside down. Keeps dead mice from falling in there.” Well, I thought, if any mice fell in these…

This is Part I of a two part treatment of new research on climate change. Part II is here. There is a new paper out, Comparing the model-simulated global warming signal to observations using empirical estimates of unforced noise, by Patrick T. Brown, Wenhong Li, Eugene C. Cordero & Steven A. Mauget. It is potentially…

I once knew a young woman who was in high school and shall remain nameless. One day I picked her up at school to drive her home, and asked how she was doing. “Depressed, actually,” she said. “Why, did something go wrong at school?” “Kinda,” she replied. “The social studies teacher was out today.” “That’s…

Lomborg in Oz

I’ve written here about some of Bjorn Lomborg’s work, generally critical of it. But the Abbot Government in Australia apparently likes what Lomborg is doing well enough to have earmarked $4 million (in some currency or another) to ensconce a version of his academically questionable enterprise right in the middle of Australian academics. I would…
