For those concerned about our imminent deaths in the furnace that the earth is soon to become - and to help us allay the fears of the kids we teach who have been exposed to too much Gretaganda - there is a wealth of data out there that show just what a hoax this all is. One particularly measured and calm presentation, factually based, is the following. It has the merit of being short and clear. (It also includes, for those of us who follow with increasing bemusement US politics, a neat little dig at AOC). There are thousands of others, mostly delivered by highly-qualified experts. I'm glad to say that I am teaching the kids I work with NOT to accept at face value everything they hear and see simply because a supposed "scientist" is talking. I've shown them what junk science is, and am happy to say that I've been supported in that by my science teacher colleagues. In my opinion, one of the greatest threats to future generations in the West is the restriction of freedoms, especially that of speech - especially the insidious "you are not permitted to offend" sort of approach that over the past few years has become the hallmark of the intolerant, totalitarian left. At this time of year, more than any other, we have in Europe the opportunity to remember how many gave their lives, directly or indirectly, to preserve those freedoms for us. One way to ensure that we retain them is relentlessly to insist that all views, ideas, stories, webcasts, documentaries, articles, conclusions, ideologies, and beliefs should be open to rigorous challenge, irrespective of who - or how many - are promoting them. In a world of so many competing media, where money-making is often the game and where malign influences and vested interests cannot always easily be identified, the best thing we can tell our students, in my view, is "challenge, check , consider."
