Soaring temperatures. Unusually hot oceans. Record high levels of carbon pollution in the atmosphere and record low Antarctic ice. We’re only halfway through 2023 and so many climate records are being broken.

    I’ll have to find the source later, but I read somewhere that each 1 degree Celsius rise in temperature reduces overall crop yields by 10%. Also, tropical forests that rely on high humidity environments will start drying up causing drastic ecological and an increase in fires. Yes, the fear mongering sells news, but that doesn’t mean you can write off climate change as a big deal.

      each 1 degree Celsius rise in temperature reduces overall crop yields by 10%.

      That sounds on the high side, so I’d want to read a source before I accept it. Let’s say it’s true for a moment, and crop yields decline by 20-40% over the next 80 years. Take a look at global wheat yields over time. The use of technology to improve yields has resulted in explosive growth to output. Our continued improvements for the next 80 years will more than make up for even a 40% reduction.

      I must be clear: I am well aware that there will be consequences to a 2-4C increase in temperature. I’m claiming that those consequences are not as bad as the millions of people dying each year at present because they lack access to cheap energy.
