Aria (Advanced Research and Invention Agency) is about to risk your well being just to run an experiment on a hypothesis, on a process in progress, on the popularized notion that climate change is a natural phenomenon within human control. Aria, in an attempt to reduce incoming solar radiation, will fund cloud seeding with reflective aerosols. * If they are successful in their effort to geoengineer the planet and, by happenstance, some Icelandic or Indonesian volcano erupts as Laki did in 1783 and Krakatoa did in 1883, you’ll be wearing a double layer of your winter clothes—or maybe wearing your winter coat in summer as people did during the “Year without a Summer” (1816) that followed the successive eruptions of first Mayon in the Philippines and then Tambora in Indonesia. Volcanoes do their own geoengineering from time to time.
I’ve written about this before. I’ve warned against doing it. But who am I? Don’t the “scientists” know better? Don’t the politicians? Sorry, Am I picking on people like Bernie Sanders, Alexeandria Ocasio-Cortez, and a host of other Democrats who, with former Presidents Joe Biden and Barack Obama, have declared climate change an “existential threat” and the cause of wildfires that spread through poorly managed forests encompassing residential areas that didn’t exist a century ago? Actually, yes, because I believe Aria’s attempt would most likely hav their approval, as a similar proposal had the Biden Administration’s approval.
That a single volcanic eruption can alter global temperatures by ejecting aerosols into the stratosphere is a lesson learned as far back as the eighteenth century. Benjamin Franklin’s suspected that Laki’s 1783 eruption affected temperatures. A century later with better world-wide interconnectedness through telegraph and newspaper reports, naturalists realized that Krakatoa altered Northern Hemisphere temperatures. If you were alive in 1992, you experienced a smaller, but similar effect, after the 1991 eruption of Pinatubo lowered average temperatures by 0.5–0.6 °C (0.9–1.1 °F) in the Northern Hemisphere and decreased global temperatures by about 0.4 °C (0.7 °F). Were the people of Aria not paying attention?
But unding has erupted into Aria’s pockets, and with no real oversight by skeptics, the “science” of blocking sunlight will probably proceed. As Dr. Sebastian Eastman puts it, “It’s theoretically possible (to cool the planet) with current day technology but there are many practical questions that would need to be answered before they could be done at scale.”
Just because something can be done doesn’t mean it should be done.
You have no say in the matter, of course. In Europe and the USA voters have put in office people who have probably never studied atmospheric physics, the history of glaciation, historical geology, the several climate classification systems, the effects of continentality, land-water distribution, elevation, latitude, cloud dynamics, ocean currents, orography, semi-permanent High and Low pressure systems, atmospheric cycles and prevailing mechanisms for moving heat around the planet, precession, axis tilt, orbit shape, Sun cycles, atmosphere stratification and chemistry, outgassing from forests, natural methane seeps including methane hydrate volatility, volcanic eruptions, and… Well, who am I to say anything that contradicts the wisdom of Bernie Sanders, Alexandria Ocasio-Cortez, and the people at Aria ready to spend UK taxpayers’ funds on seeding the sky with aerosols?
