Too Many People

People have often told us ‘well there are just too many people in the world’. While population growth is important it cannot be used to dismiss the causes of climate change so easily. It also raises the question about whether they are saying ‘it would be good if millions of people died’. First of all […]

Correlation Does Not Prove Causation

One of the statements that is often quoted is ‘correlation does not prove causation’. That means just because two things seem to go up or down together it does not prove that one causes the other. For example the record of CO2 concentration in the atmosphere is correlated with temperature – for example the graph […]

Nuclear Power: Systemic Risk And Climate Change

Summary Humanity faces a large number of challenges in future decades including increasing population leading to increased competition for dwindling resources and climate change. These challenges could lead to ‘collapse of civilisation’ i.e. the complex system of exchange of good and raw materials, energy, food and water would be susceptible to shocks or many even […]

In Defence Of Teresa May

This is not to mean that I do not find many of the policies of the present government wrong or that I somehow feel sorry for her. However, I do not think it is useful to hurl a string of personal abuse at her – that she is depraved, evil, stupid, emotionally deprived, bordering on […]

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 0ºC. 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 […]

Climate Change: It is the extremes that kill rather than the average

This post is not about any particular prediction but is […]

Lest We Forget: Civilian Casualties of War

Although it is difficult to estimate the number of civilians killed due to war what is not difficult to realise is that they are usually forgotten when we ‘remember’ the fallen. We remember those sacrificed on the battlefield but ignore the civilians bombed, shot, gassed and starved in equal or greater numbers1. This does not […]

The Difference Between Weather And Climate

I have had people say to me on many occasions “if they cannot predict tomorrows weather how can they predict climate change”. This is a common misconception that climate and weather are the same thing. Think about heating up some water. As you heat it the temperature increase will not be uniform. The warmer water […]
