Harvard scientists will soon send chemicals into the atmosphere to test whether a last-ditch planet-hacking plan could keep Earth habitable - ultimately using Chemtrailing

To help cool the planet, some scientists are proposing the use of solar geoengineering, a method in which chemicals are sprayed into the atmosphere to reflect the sun's rays back into space.
A team of Harvard scientists plans on starting a real-world solar geoengineering study in early 2019.
In late November, researchers at Harvard and Yale published their findings about the potential costs of implementing solar geoengineering methods. The researchers found that the most cost-effective way of releasing sulfate particles into the stratosphere would be using a high-altitude aircraft. Such a program would cost about $2 billion per year for the first 15 years of use, according to the study published in Environmental Research Letters.
