A new Ian McEwan novel is always an event, although I must confess that this one is not very new - it was published in 2010. The world (well, me anyway) has been waiting for a long time for the great climate change novel and if anyone can do it, McEwan can.
Ian McEwan is known for his grasp of science and for novels that interweave rational argument and emotion. Enduring Love features a science writer, Saturday a neurosurgeon and now, with Solar, we meet Michael Beard, a Nobel prize-winning physicist.
So how does McEwan tackle this most complex and rather boring subject? Dystopian futures and eco-thrillers have been the main weapons of choice for climate change novelists, but McEwan does something different - he makes us laugh.
Michael Beard is a fat, randy has-been who has done nothing significant since his prize-winning Beard-Einstein Conflation many years ago. Offered a place on an artist's trip to the Arctic to examine the effects of climate change, Beard jumps on a jet to Norway (carbon off-set of course). Soon he is getting his delicate parts caught in a zip while urinating at minus forty degrees and fleeing a hungry polar bear on his skidoo.
Getting on board the solar bandwagon, Beard reassures his business partner, "Here's the good news. The UN estimates that already a third of a million people a year are dying from climate change. Bangladesh is going down because the oceans are warming and expanding and rising. There's drought in the Amazonian rainforest. Methane is pouring out of the Siberian permafrost... Now the eastern Antarctic is going."
Yes, this is black comedy at its best. The boot room on the frozen-in boat where the artists are staying becomes a metaphor for the planet as it descends day by day into further chaos.
"How were they to save the earth," Beard wonders, "when it was so much larger than the boot room?" There is also a laugh-out-loud moment when Beard helps himself to a stranger's chips. This in turn becomes a metaphor for our need to re-examine known facts in light of new evidence.
While Solar might not be the hallelujah moment in fiction that climate change activists would hope for, it does carry an important message - a flawed scientist does not mean that the science is wrong.
You can also just read it for laughs.
