Don Webb. Fine Green Dust. (Fantasy & Science Fiction, May/June 2011).
Climate change is making it very hot in Austin, Texas, and a middle-aged teacher is struggling, as with many, to deal with the impact on his daily life. Unlike others, particularly the young, who can see a way of coping with the change, of evolving to deal with the heat. In a wry tale, the green dust enables them to be much more cold-blooded about matters.
Title correction: the first word is “Fine”, not “The”.
Thanks for the review, as always.
