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 [...]

Part 1 of a series of 5 for NextGen Journal. What’s wrong with these statements? I believe in global warming. I don’t believe in global warming. We should hear all sides of the climate change debate and decide for ourselves. Don’t see it? How about these? I believe in photosynthesis. I don’t believe in Newton’s [...]

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 [...]

I apologize for my brief hiatus – it’s been almost two weeks since I’ve posted. I have been very busy recently, but for a very exciting reason: I got a job as a summer student of Dr. Steve Easterbrook! You can read more about Steve and his research on his faculty page and blog. This [...]

Last time, we talked about the energy budget – the process of radiation coming in from the sun, being absorbed by the Earth, and then emitted as infrared radiation, which we perceive as heat when it hits us. Remember that this outgoing emission of energy is what determines the temperature of the Earth. So how [...]
