"Researchers are also looking into launching a giant parasol into space to manage the amount of solar radiation hitting Earth. This idea has been around for decades, but has only recently gained momentum.

For example, a 2018 paper from the Journal of Aerospace Technology and Management describes launching what the authors call the HSS, or Huge Space Shield. The plan is to put a thin, wide sheet of carbon fiber into a Lagrange point, which is a relatively stable point in the complex system of gravitational pulls between the Earth, moon, and sun. The sheet would only block a small portion of solar radiation, but it could be enough to drop global temperatures below the 1.5 degrees Celsius limit set by the International Panel on Climate Change.
