Question to Dyson: &quot;Are climate models getting better? You wrote how they have the most awful fudges, and they only really impress people who don&#x27;t know about them.&quot;<p>&quot;I would say the opposite. What has happened in the past 10 years is that the discrepancies between what&#x27;s observed and what&#x27;s predicted have become much stronger. It&#x27;s clear now the models are wrong, but it wasn&#x27;t so clear 10 years ago. I can&#x27;t say if they&#x27;ll always be wrong, but the observations are improving and so the models are becoming more verifiable.&quot;<p>&quot;It&#x27;s now difficult for scientists to have frank and honest input into public debates. Prof Brian Cox, who is the public face of physics in the UK thanks to the BBC, has said he has no obligation to listen to &quot;deniers,&quot; or to any other views other than the orthodoxy. That&#x27;s a problem, but still I find that I have things to say and people do listen to me, and people have no particular complaints.&quot;<p>Further illustration: <a href="http:&#x2F;&#x2F;www.bishop-hill.net&#x2F;blog&#x2F;2015&#x2F;10&#x2F;14&#x2F;top-french-weatherman-suspended-for-forbidden-views.html" rel="nofollow">http:&#x2F;&#x2F;www.bishop-hill.net&#x2F;blog&#x2F;2015&#x2F;10&#x2F;14&#x2F;top-french-weathe...</a>.<p>&quot;France&#x27;s top weatherman, Philippe Verdier has been suspended from work for publishing a book about climate change which suggests that the IPCC might be just a tad unreliable and more than a little politicised.&quot;
