For this first week of tracking the Climate Index, the measurement of high temperatures in the world’s largest cities has been in negative territory, showing daily averages that are slightly below normal… until now. Now, the cities of the world are warming up. The Climate Index for Friday was 1.79 – that’s 1.79 degrees F. above normal.
No single day high temperatures in any single place proves that global warming is taking place, of course. That’s why I’m tracking the Climate Index day after day after day. Eventually, we’ll be able to look at this data and see some long-term trends.
The predictions of climatologists who built models of likely anthropogenic climate change in the past haven’t come true – they’ve been exceeded. Yesterday, Senator Sheldon Whitehouse stood up and advised his colleagues to pay attention to the growing climate crisis. The Senator said:
” Climate scientists predicted the atmosphere would warm, and the atmosphere is warming. Climate scientists predicted the ocean would absorb heat, and sure enough, the ocean has absorbed heat and ocean waters are warming. Climate scientists predicted the ocean would absorb CO2 and that would then lower the pH level of our ocean waters. The ocean is now more acidic than it has been in two million years, threatening coral reefs, shellfish, and the tiny creatures, such as plankton, that make up the base of the entire oceanic food chain. Climate scientists predicted glaciers and Arctic sea ice would melt and, sure enough, we are seeing record melting.”
