Spectator by Seema Goswami: Warming signs

I felt the first stirrings of disquiet when I ventured out for my usual late-afternoon walk last week. The sun, which had until then been a balmy presence, was suddenly glowering angrily down on me. Such was the intensity of its gaze that in a few minutes I had to remove the wrap I was wearing over my shirt. And when even that didn’t do the trick, I had to admit defeat and find refuge in the shady parts of the park.
