This eye-catching chart is from this article on Phys.org. The article says that a warm climate is more sensitive to changes in atmospheric CO2. Which means that a given rise in atmospheric CO2 raises global average temperatures more when the temperature itself is higher. Not good news. I added the red dot, which shows where the global temperature anomaly is likely to be on the same scale as the long-term section of the chart on the left. Click to enlarge. [Hat tip to JPratt27]
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. 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.
BTW, clicking on most charts will produce the original-sized, i.e., bigger version.
