Guest essay by Jim Steele, Director emeritus Sierra Nevada Field Campus, San Francisco State University and author of Landscapes & Cycles: An Environmentalist’s Journey to Climate Skepticism Recently advocates of CO2 catastrophic climate change have been trumpeting a new paper in PNAS by Kyle C. Cavanaugh et al :“Poleward expansion of mangroves is a threshold…
Addendum by Anthony: This graph is an eyebrow raiser. The infrastructure at Yosemite has increased to handle increased tourism, and the weather station records this by a reversal of the Tmin and Tmax relationship. In this case, the heat sinks are a road, a building, and stacked metal pipe and beams surrounding the station, which…
Essay by Jim Steele, Director emeritus, Sierra Nevada Field Campus, San Francisco State University The heat wave and near record-breaking temperatures in Death Valley provides a superb teaching moment to show why CO2 has nothing to do with heat waves whether the record is ever broken or not. Most heat waves are associated with dry…
Back in 2007, Wired Magazine mused: It’s only slightly less ridiculous than the other bee killing theory that year – cell phones. I published a story about the loony idea that was proposed by some researcher in Europe about “cell phone radiation may be killing bees”. I pointed out that it was garbage then, as…
Two years ago, it was “Study says global warming shrinks birds” now thanks to impressive further study, they’ve discovered it’s “Bigger birds in central California, courtesy of global climate change.“ Can’t they get their story straight? Why don’t they ask Jim Henson Hansen? From San Francisco State University Bigger birds in central California, courtesy of…
From San Francisco State University another indication that nature is such a poor engineer that phytoplankton can’t adapt to a small change in ocean pH. But then again it is a closed lab experiment, not the ocean, and there’s those weasel words of “might”, “could”, and “may”. Researchers explore plankton’s shifting role in deep sea…
I just finished reading: Turning a More Vivid Shade of Green: Caltrans Takes a Stand on Climate Change, Global Warming from the Caltrans website. The road sign below (from this online sign generator) rather sums up what the essay says and the scale on which it says it. Only one small problem here, climate doesn’t…
