The vast majority of climate scientists believe that climate change is largely caused by humans. Survey after survey confirms this: the average of the data below is 90%. And less than 4% of the average of 8 surveys says that there is little or no human effect. So why do the climate change denialists refute this? Do they also tell their brain surgeon how to do his job? Their doctor? The aviation engineer who designed their plane? The boffins who created computers? The engineer who built the bridges they cross every day? The architect who designed skyscrapers into whose lifts they daily trust their lives? Of course not! But, don't you know, yesterday was a bit chilly, so, no there is no such thing as global warming.

But I can't by law give you advice, and I do make mistakes. Remember: the unexpected sometimes happens. Oddly enough, the expected does too, but all too often it takes longer than you thought it would, or on the other hand happens more quickly than you expected. The Goddess of Markets punishes (eventually) greed, folly, laziness and arrogance. No matter how many years you've served Her. Take care. Be humble. And don't blame me.
