Harvard Profs Plan Geoengineering Experiment, Igniting Ethics Debate
Researchers at Harvard plan a geoengineering experiment injecting calcium carbonate dust high over the Southwestern US to see if it can help lower the temperature of the air below.

CleanTechnica Report: A case study into a technology that should be set aside until 2050,…
Researching air-carbon capture for use post-2050 remains a very good means of establishing the intellectual capital and basic technologies for when it makes sense to use them. But attempts to commercialize them today are premature.
Oceans Need Geoengineering, Not The Atmosphere
Solar geoengineering is a bandaid on the symptoms, not a cure for the causes. It’s like putting out the fires caused by an arsonist wandering around with a flamethrower instead of confiscating and shutting off the flamethrower itself. Global heating would slow and stabilize if we stopped forcing more CO2 into the system. But it’s unclear if that’s as true for oceanic carbon uptake.
“Dimming The Sun” — The Killer Argument For A Profoundly Dangerous Climate Fix
A handful of scientists want to dim the sun to cool the planet. A recent debate shows the idea is perilous, impractical — and immensely appealing.
Chevron’s Fig Leaf Part 7: Carbon Engineering’s Fuel Is At Best 25x The Cost, 35x…
Carbon Engineering will produce transportation fuels that cost 18-25 times more and have 22-35 the CO2e emissions as just using electricity in an EV
Chevron’s Fig Leaf Part 6: Carbon Engineering’s Air-To-Fuel Plan Is Even Worse
Carbon Engineering is planning to build high-cost and comparatively high-emission transportation fuels by combining their expensive CO2 with hydrogen which they will get via expensive electrolysis.
Chevron’s Fig Leaf Part 5: Who Is Behind Carbon Engineering, & What Do Experts Say?
Air carbon capture, especially as Carbon Engineering is doing it, is a fig leaf for the fossil fuel industry.
Chevron’s Fig Leaf Part 4: Carbon Engineering’s Only Market Is Pumping More Oil
Carbon Engineering’s solution is only useful in tapped-out oil wells and as greenwashing for fossil fuel companies.
Chevron’s Fig Leaf Part 3: Carbon Engineering’s Scale & Power Problems
Carbon Engineering’s solution would require 2-kilometer long, 20 meter high walls of noisy fans to capture 4 orders of magnitude less carbon than would be useful.
Chevron’s Fig Leaf Part 2: Carbon Engineering Burns Gas For 0.5 Tons Of CO2 For…
Carbon Engineering’s solution is a natural gas hog that produces a half ton of new CO2 for each ton captured from the air.
