Researchers are exploring ways to limit the amount of sunlight that gets to Earth and help to cool our climate. One method involves spraying aerosol particles into the atmosphere that would reflect sunlight away from the Earth, thereby slowing warming. Another method involves making clouds or the Earth's surface brighter so that they reflect more sunlight back out into space.3 MIT researchers are exploring floating frozen bubbles made of a thin film above Earth to reflect solar rays, called 'Space Bubbles'. The Biden administration is considering the idea of artificially cooling the planet by reflecting away some sunlight, citing the lack of progress fighting global warming

Yep. Already doing it with chemtrails. So they say.
