Today I looked at the stats for the blog and was amazed to find there were  over 7000 viewers for just today which is a record. The odd thing is that they were not reading my latest post. So what has made this sudden jump. Is it you, Dave? 

I am reproducing the post below, of a discussion I had with a reader back in October 2021. Any comments welcome.  

 My position is that there is a modest amount of global warming, which, as the IPCC report says, is about 1.1 degrees C since around 1850, which was at the end of the Little Ice Age. (I don’t think anyone would think that this was an ideal climate!) Some of this warming is natural – most of that before 1950 and about half of that post 1950 is what scientists have estimated. So approximately half a degree C can be attributed to man. That is very modest and cannot by any means be called an emergency.     The problem is that politics has taken over from the science and this issue has now been captured by extremists, such as Extinction Rebellion and, unfortunately, the government has listened to these extremists and they are now fully embarking on a very costly policy of trying to eliminate fossil fuels, regardless of the fact that other major industrial nations, such as China and India, are increasing their fossil fuel usage which means our costly efforts will be wiped out.  Unilateral action is pointless, just as with nuclear disarmament.  

The language now being used is very extreme with terms like “climate emergency” being used as an everyday phrase.  It is the use of this extreme language, along with almost daily clips of extreme weather events on our main news channels which is designed to convince a sceptical public that the vast expense of decarbonisation (government estimate is £1.4 trillion up to 2050) is justified

Extreme weather has always occurred and the data show it has not increased in either severity or quantity when measured over the long term.   I am very concerned for the residents of the UK who will have to pay heavily for this and so I believe it is very important to speak up as a voice of reason.

My reader I Walker replied as follows:
I’m struggling to follow your logic.

The IPCC report says "Human-induced global warming has already caused multiple observed changes in the climate system (high confidence). Changes include increases in both land and ocean temperatures, as well as more frequent heatwaves in most land regions (high confidence). There is also (high confidence) global warming has resulted in an increase in the frequency and duration of marine heatwaves. Further, there is substantial evidence that human-induced global warming has led to an increase in the frequency, intensity and/or amount of heavy precipitation events at the global scale (medium confidence), as well as an increased risk of drought in the Mediterranean region (medium confidence)."

This appears to contradict your opinion that there is no emergency. Are you contesting the credibility of the IPCC’s report?

My resonse:

As I wrote, the global rise in temperature caused by humans is only about 0.5 degrees C. The rest is natural, so is it credible that this tiny change could cause the changes in climate being claimed? Also note that 1850 was the end of the Little Ice Age. If we go back to the Medieval Warm Period, there is good evidence that temperatures were warmer than today. For example Greenland was able to have a human settlement which farmed the land. It was then vacated as temperatures dropped. At several locations evidence of forests have been found beneath the retreating glaciers which have been dated as only a thousand years old. Again indicating higher temperatures within that time span. What you need to note is that the IPCC is a politicalz organisation, not an independent scientific body. What we have is a man-made emergency driven by political expediency.

Mr Walker replied again as follows:

The IPCC’s role is to analyse the science, they use levels of ‘confidence’ not shape it to a political ideology. In any case, NASA also agrees with the conclusions (that the rise in temperature is driven by man, not nature), as do most scientists. To suggest that the temperature rise is normal puts your opinion in opposing to mainstream scientific understanding. What qualification or credible source do you use to justify this position, other than your personal, subjective opinion?

My final response is below:

The IPCC’s role is to identify and quantify the human role in changing the climate, which, unsurprisingly it does. – If it did not then it would not be justifying its existence. There can be no doubt that this subject has now become a highly political one and it is quite impossible to separate the science from the politics. The actual science proving that the temperature rise is mainly down to CO2 is very weak, as there are many other factors that are simply not understood. For example the role of clouds. Research into this is simply ignored because it throws doubt over the whole CO2 driven hypothesis. My views are shared by a number of highly qualified experts on the subject. You need to read more widely on the subject and get informed on the very credible alternative hypotheses. Have a look at the Global Warming Policy Foundation website.
