There's also the North Atlantic Oscillation (NAO) to screw with our weather - this was only discovered 90 odd years ago. Plus the magnetic pole is due a flip as well as an ice age or a super-tsunami.
Finally, a large meteorite is overdue that could stop global warming; either by wiping out a large amount of the population (and their carbon emissions) or by throwing up loads of material into the atmosphere that will block the warming from the sun.
Finally, fossil fuels will dwindle and other sources of energy will need to be used. So in 50-100 years time when we all have cold fusion reactors powering our cars, ships, trains and planes, then the problems of the 'sandalista' will need to change tack.
I would rather bet on West Ham winning the Premiership 3 times over the next 100 years than try to predict what the weather/climate/environment has in store over the same time period.
