I am presenting a Commentary which has no attachments because their inclusion would make it difficult to circulate the Commentary with the attachments and because I can send an attachment to those who wish to see it. The whole Commentary with attachments will also be in my web site. When controversial policy issues come under discussion in the public arena, there are often weird suggestions proposing government action. And the media publicises a supposed issue to give the impression that ““something needs to be done”. Take for example the idea that action to solve the dangerous warming threat might come if school children miss school one day and parade down the streets all over the country (and in other countries too) with placards instructing our elected politicians that urgent action is required. This is just what has happened. But has this publicity simply led to the school children going back to school and are people a bit tired of being told that much quoted models “prove” that climate change action is needed by government? Do such models actually so prove.
