At the time of the ludicrously inept propane-bomb attacks in London and Glasgow last summer, my biggest worry was that apparently those involved in the attacks were practising medicine. I would always hope to be treated by doctors with better knowledge of basic science than was demonstrated by those terrorists.
It is now emerging that one of the doctors, at least, was just the brother of the Glasgow suicide arsonist, who may or may not have been aware of the direction of his brother's activities, but who is not accused of being active in planning them. That's good news; there's every chance that the defendant, Sabeel Ahmed, may be a competent doctor.
The idiot arsonist himself was no doctor, but, apparently, a "climate change expert".
I would love to claim that climate alarmists generally are ignorant of chemistry and physics, but that is clearly not the case. I might with slightly more justification claim that there is a common tendency involved, which is to jump to worst-case conclusions. It is actually possible for a propane/air mixture to explode very destructively, it's just very very unlikely without a very sophisticated process of using the right proportions and mixing very well. It is possible that the feedback effect of the climate system to CO2 forcing could be positive rather than negative, but that likewise is very unlikely. The alarmist case is based on climate models that appear to show that the feedback is indeed positive.
As an argument, that's still a bit of a stretch; it's worth thinking about it but I wouldn't expect it to change anyone's mind. The actual irony of this case is that Ahmed S. was pursuing an activity -- climate alarmism -- which has a serious chance of weakening or destabilising western civilisation. Even competent terrorism is less of a threat than climate alarmism. To give up green activism in favour of incompetent terrorism is, for an opponent of Western domination an own goal of Gary Sprake proportions.
