Expert = someone with deep knowledge of a subject and makes qualified guesses (called theories) and they can still get it wrong...
I recall in the recent past Government "Experts" telling us to get diesel vehicles as they were more efficient...!
As I've said before, a genius is someone who doesn't make the same mistake ONCE.
However, again you shoot yourself in the foot whilst trying to prove your point. The "experts" maintained - correctly - that diesel cars emitted less Sulphur Dioxide, which was the issue raised by the government at the time. However, I also recall "experts" at the time raising the issue of particulates - but nobody was interested.... "only easy answers need apply". So, the answer given depends upon the question asked..... and the questions are not asked by "experts". Then their replies are taken by the media and boiled down to a headline (because all those caveats are just boring
) and implemented by a government that wants to get itself out of an immediate hole ASAP. Result - predictable.
The issue of climate change - as you keep pointing out - was first spoken of as another "big freeze", because the wrong question was asked. The concept of "Global warming" is equally misunderstood. The climate is a complex beast - a change in overall temperature can affect weather patterns and result in all sorts of climactic issues, from once-in-a-lifetime freezes that happen with unusual frequency, or once-in-a lifetime flooding, that happens twice in a decade or once-in-a-lifetime droughts, etc., etc. and, it is undeniable that the overall temperature is increasing, it can be measured. All these issues are caused by the same basic mechanism - but it's all too complex for the headlines (and those who react to them) to understand, so they call it "Global Warming" ..... and then point out how it's getting colder.
They say that a little learning is a dangerous thing - and the rise of the internet has given easier access to information that people are not necessarily able to understand - and, in parallel, it has given those who either misunderstand, or deny the evidence, the ability to spread their misinformation..... because "everyone's an expert now".
So, ask yourself - if that's true, are you happy for a plumber to operate on you, because he can see anatomy sites online??
