But Manchin’s shot should ring in his fellow Democrats’ ears, warning them that it is time to come up with an alternative to regulating carbon, a Plan B for climate change. I suggest they try smoke and mirrors — literally.
Scientists are already pondering the use of smoke (sulfur dioxide injected into the stratosphere) and mirrors (installing reflectors made of metal or lunar glass a million miles from Earth) to cool the planet. It’s time for policymakers to get serious about these and other “geoengineering” proposals to cool the Earth and remove excess carbon.
None of this means giving up on carbon reduction, which remains the only sure way to prevent man-made climate change. But as the failure in Congress to reach consensus slows progress toward an international agreement, the wasted time could be used to create a fallback plan…
To keep the Earth from absorbing warmth, we could paint roofs, roads and pavement white. We could plant lighter, more reflective grasses, or cover the deserts with reflective aluminum. Boats or planes could spray ocean clouds with sea salt to make them whiter; pumping tiny particles into the atmosphere could mimic the cooling effect of volcanic eruptions.
