led by Yale University researcher Wake Smith. Those jets would themselves release copious amounts of carbon dioxide high up into the atmosphere, it's worth noting. But despite the harmful emissions, Smith claims it'd still be worthwhile.Aerosol Shade According to the plan, microscopic sulfur dioxide particles — that's the stuff you smell from a burnt match — would be released from 125 air-to-air refueling tankers flying at 43,000 feet over the planet's poles.
These particles would then block some sunlight from the surface below, shielding the polar regions from the Sun's heat., just over 13 tons of particles released at just the right times of the year could cool the polar regions by an appreciable 3.6 degrees Fahrenheit.Plans for solar geoengineering have been met with vocal opposition, with experts arguing that releasing harmful carbon dioxide emissions from planes flying at high altitudes is a terrible idea.
They also say that solar shading could have unintended consequences, including negative effects on agricultural systems, according to
