David Attenborough’s BBC show would better have been called “Climate: Change The Facts”

… If you are going to present a film called Climate Change: the Facts the very least you should be doing is, well, presenting the facts. Well here they are, in two of the areas which made up such a hefty part of the film: wildfires and hurricanes. Are wildfires increasing? They are according to Attenborough. One of the scientists who takes part in the programme, Professor Michael Mann of Penn State University, goes as far as to say there has been a “tripling in the extent of wildfires in the Western US”. He is not specific about his evidence for this claim, nor said over what timeframe wildfires are supposed to have trebled, but it is not a fair assessment of the data collected by the US Environment Protection Agency (EPA). This shows no upwards trend in the number of wildfires in the US over the past 30 years.

But then again, go back further, to the 1920s, and you see that both the number of US wildfires and acreage burned in them has plummeted.

That is nothing to do with the climate – more down to firefighters getting better at tackling fires. But that reduction in wildfires – which, after all, were occurring naturally long before Europeans arrived in the US – has brought with it a problem: deadwood is not being cleared out at the rate which it used to be. As a result, when a wildfire does take hold, it tends to be a more powerful fire, which is one reason large acreages tend to get burned when fires do take hold. That was a large part of the debate which followed the wildfires in California last November.

But I know what will have entered the heads of many of Attenborough’s viewers: that wildfires are being caused by climate change and that is that. […]
