Jimmy Dore: Geologist and climate change critic Tony Heller joins the show to discuss the recent IPCC admission that the most extreme high-emissions scenario (SSP5-8.5), which produced apocalyptic warming projections of 4°C by 2100 and fueled many media scare stories over the past 15 years, has been officially labeled "implausible" for the 21st century based on trends in renewable energy costs and climate policy. He notes that James Hansen, NASA's leading expert in 1988, predicted that lower Manhattan would be underwater by 2018—which did not happen—and that climate alarmism has been driven by exaggeration since the 1970s, when Steven Schneider openly advocated telling scary stories to get the public's attention.
Heller warns, however, that the climate scare movement will likely return in a few months, as a severe drought and heatwave in the western US—caused by low snowpack and overuse of Colorado River water for decades—will be blamed on Trump's cuts to climate research funding. He says that the western US has been using more water than is available for over a century, and that an expected El Niño could provide temporary relief, but long-term solutions are needed since cities like Phoenix and Las Vegas cannot be relocated.
