Climate Change Facts

Is climate change real?

There has been much in the media recently about climate change skeptics, such as Lord Monckton. They challenge the concept that climate change is occurring and that it is caused by humans. Why spend money developing solar power and other renewable energy sources if this is the case? Let us look at the facts.  Continue Reading…

Is climate change bad?

Climate change poses an existential challenge for the future of the human race. Most climate change impacts confer few or no benefits, and may do great harm at considerable cost. The following list examines the possible outcomes of unchecked climate change.  Continue Reading…

Nearly all hypotheses will fall by the wayside during this testing period, because only one is going to answer the question properly, without leaving all kinds of odd dangling bits that don’t quite add up. Bad theories are usually rather untidy.  Continue Reading…

Over the same period temperature measurements of the air and sea showed that the Earth was gradually warming. It was not surprising therefore for most scientists to put two and two together and assume that it was the warming sun that was increasing the temperature of our planet.  Continue Reading…
