J.G. Ballard's " The Drowned World " is set in a future where our sun has entered an intense phase of solar flare activity, causing the temperature to rise on Earth, polar ice caps to melt, end of civilisation, yadda yadda yadda. You know how this sort of thing works. Ballard captures the atmosphere of intense heat, and the lethargy and disinterest it causes in his characters really well. So well, in fact, that the lethargy and disinterest proved contagious and I was bored stupid throughout the book. It was written in the early sixties, and it is showing its age. The geophysics is a bit dodgy - the sun is pumping out lots more heat and energy, and yet the climate only gets hotter. There should have been high winds, constant storms from all that warm air expanding. The female character is utterly pointless, having no opinions or ability to think for herself. She's just a device to give the hero something to do. The characters are all very British, with stiff upper lips...
