Just had a look at the latest sunspot data and I think I shall be investing in winter sports companies and some serious cold weather gear. Sunspot cycle 24 is late, and the tail end of sunspot cycle 23 is coming up with a lot of 'spotless' days. This does not bode well for those who enjoy sunbathing.
The upside is that the cooler climate we should be enjoying as a result of the lower solar output generally means better sea fishing. Cooler upper layers in the sea mean better conditions for plankton, more plankton means more fish food, more fish food means that there will hopefully be more fish.
Looks like my best investment is going to be some long underwear and a spare set of snow tyres for fall.
