A Sunshade to Protect the Earth’s Climate Would be Perforated by Micrometeoroids
<p>Imagine yourself on the open deck of a ship which happened to sail just under this meteor’s fireball in 2014. Given the rainy weather at that location, you might have had an umbrella next to you as I did during our expedition. In that case, your instinct would be to shield your body by opening the umbrella overhead and hope for protection against the rain of molten droplets from the meteor. The only problem is that the thin film making the umbrella would have been perforated instantly by the iron droplets, offering no protection whatsoever. This thought crossed my mind when I read yesterday a <a href="https://www.nytimes.com/2024/02/02/climate/sun-shade-climate-geoengineering.html" rel="noopener ugc nofollow" target="_blank">major story</a> on the front page of the printed <em>New York Times</em>, regarding an initiative to protect the Earth’s climate from rising temperatures by a sunshade.</p>
