Also published at Skeptical Science This is a climate model: T = [(1-α)S/(4εσ)]1/4 (T is temperature, α is the albedo, S is the incoming solar radiation, ε is the emissivity, and σ is the Stefan-Boltzmann constant) An extremely simplified climate model, that is. It’s one line long, and is at the heart of every computer [...]

I know that many of you will be at the annual American Geophysical Union conference next week in San Francisco. If so, I’d invite you to come by and take a look at our poster! It will be up all Thursday morning in Halls A-C, Moscone South. I will be around for at least part [...]
My Dishpan Climate Model

About two years ago, I discovered the concept of “dishpan climate models”, through Iain Stewart’s Climate Wars documentary. The experiment is pretty simple: a large bowl filled with water (representing one hemisphere of the Earth) with a block of ice in the middle (a polar region) rotates on a turntable with a Bunsen Burner (the [...]
A Vast Machine

I read Paul Edward’s A Vast Machine this summer while working with Steve Easterbrook. It was highly relevant to my research, but I would recommend it to anyone interested in climate change or mathematical modelling. Think The Discovery of Global Warming, but more specialized. Much of the public seems to perceive observational data as superior [...]
Wrapping Up

My summer job as a research student of Steve Easterbrook is nearing an end. All of a sudden, I only have a few days left, and the weather is (thankfully) cooling down as autumn approaches. It feels like just a few weeks ago that this summer was beginning! Over the past three months, I examined [...]
Modularity

I’ve now taken a look at the code and structure of four different climate models: Model E, CESM, UVic ESCM, and the Met Office Unified Model (which contains all the Hadley models). I’m noticing all sorts of similarities and differences, many of which I didn’t expect. For example, I didn’t anticipate any overlap in climate [...]
Climate Models on Ubuntu

Part 1: Model E I felt a bit over my head attempting to port CESM, so I asked a grad student, who had done his Master’s on climate modelling, for help. He looked at the documentation, scratched his head, and suggested I start with NASA’s Model E instead, because it was easier to install. And [...]

Working as a summer student continues to be rewarding. I get to spend all day reading interesting things and playing with scientific software. What a great deal! Over the weekend, I ran the “Global Warming_01″ simulation from EdGCM, which is an old climate model from NASA with a graphical user interface. Strangely, they don’t support Linux, [...]
Tornadoes and Climate Change

Cross-posted from NextGen Journal It has been a bad season for tornadoes in the United States. In fact, this April shattered the previous record for the most tornadoes ever. Even though the count isn’t finalized yet, nobody doubts that it will come out on top: In a warming world, many questions are common, and quite [...]
Beautiful Things

This is what the last few days have taught me: even if the code for climate models can seem dense and confusing, the output is absolutely amazing. Late yesterday I discovered a page of plots and animations from the Canadian Centre for Climate Modelling and Analysis. The most recent coupled global model represented on that [...]
