Plastic – A Waste Of Energy

One of the reasons for doing this calculation is because many people do not realise the energy they use by ‘consuming’ various products and their packaging. The Calculation The UK throws away over 3 million tonnes of plastic every year1. Some estimate are 5 million tonnes2. I am not going to worry too much about […]

The Climate Change Emergency

The following was written by Emma Bateman as part of our response to Lowestoft Council declaring a Climate Emergency1. Most of the information in it is from the UK Climate Change Risk Assessment 2017 Evidence Report from the Committee On Climate Change2. There is a growing understanding among the public that climate change is having […]

Air Travel Adverts On Facebook

I quite often get adverts for air travel on my facebook page so I post comments about the impacts of flying has on the environment. I occasionally get people liking my comments and some other people have done similar posts. I also get people arguing against me. However, at least it has made them think […]

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 […]

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 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

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 […]
