When You Heat Things Up They Do Not Necessarily Get Hotter

Let us start by looking at a couple of examples. First of all you take a pie out of the freezer and put it in a hot oven. After about 20minutes you check its temperature – it is still frozen in the middle and at 0ÂșC. After another 20 minutes you check its temperature and […]

Is Climate Change Based On Computer Models?

The idea of greenhouse gases such as CO2 is causing climate change is based on fundamental physics and chemistry and not on elaborate computer models. In fact the first calculations on the effects of greenhouse gas emissions was done by the chemist Svante Arrhenius over 120 years ago1. The idea that greenhouse gases trap infrared […]

A lot of the information give about the affects of climate change are about what happens to the average temperature, the average rainfall etc. However, it is important to realise that changes in the average also affect the probability of extreme events much more significantly. This post is not about any particular prediction but is […]

The Size Of The Atmosphere

I have had several discussions where people have said that the atmosphere is so enormous than man could not affect it. When you look up at the sky and think about the size of the Earth it is not difficult to see why they think this. I began to wonder what volume it would take […]

The Earth should emit as much energy as it receives from the Sun

This is something that I wrote quite a while ago. Basically the Earth has to emit as much energy as it receives from the Sun or else it will get warmer. The physics of this is quite well understood. The orgininal question was about using rockets to boost the earth into a higher orbit and […]
