While denialists witter on about how cold it is in the USA ( Alaska is warmer than Florida) it's mid-summer here in Oz and we're having record, record heat. That by itself of course doesn't prove there's global warming, but if we know (and we do) that global temperatures are rising rapidly, then a record heat wave is significant. And it's likely to be followed by more records being broken. And then even more. How long before significant chunks of the world become uninhabitable in summer?
Disclaimer. After nearly 40 years managing money for some of the largest life offices and investment managers in the world, I think I have something to offer. These days I'm retired, and I can't by law give you advice. I do make mistakes, but I try hard to do my analysis thoroughly, and to make sure my data are correct. Remember: the unexpected sometimes happens. The expected does too, but all too often it takes longer than you thought it would.
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.
