The climate appears to be changing in American attitudes about global warming.
The evidence lies in the graph above from a new Gallup survey. This graph got far less attention this week than a much sharper year-on-year spike in worry and the highest level of belief (in 15 years of tracking) that humans are the main cause.
Based on the short-term shifts, some campaigners already say they see a “tipping point.”
I’d love to think so, but I wouldn’t count on it. Read on for my reasoning. CONT.
