[ Sample weather forecasts for 2050 ](
http://www.theguardian.com/world/2014/sep/01/un-weather-forecasts-2050-climate-change-floods-drought ) might show people what global heating means in practice. Remember that 2100 will be much worse than 2050. Our reality resembles the film, [ The Day the Earth Caught Fire ](
http://www.theguardian.com/environment/blog/2014/sep/01/doomed-earth-science-fiction-climate-reality ) , though not at the same speed. I think the writer doesn't really understand science fiction; he thinks it is supposed to be a comment on our world. As a famous critic (was it Samuel Delaney?) pointed out, people who don't really understand science fiction tend to perceive it as allegory, a comment on something else, rather than a fictional world in which the events described happen. This is the heart of science fiction. I once heard a song on the radio that talked about birds' disappearing in the sky. What an alarming idea! I recall imagining what I'd ask if I saw that really happen. Were they being destroyed, or transported elsewhere? What's the cause — a natural phenomenon, a technological accident, a weapon? Would it get me next? Then I realized the song did not mean it literally, only that the birds were flying off into the distance. How pedestrian! Their disappearance would have been far more interesting. This made me realize that I have a science-fictional way of understanding a story.
