Everybody who did feel a total eclipse knows temperature goes down and light dims. So the idea is to build something that would stay between us and sun all year long...But this is easier, at least theoretically, than you might intuit. There's a gravitationally quasi-stable point, in between the Earth and the Sun, which will always effectively dim the light from the Sun. Known as the L1 Lagrange point, it's the ideal location for a satellite that you wish to remain directly between the Earth and the Sun. As the Earth orbits the Sun, an object at L1 will constantly remain in between the Earth and Sun, never straying at any point throughout the year. Its physical location is in interplanetary space: approximately 1,500,000 kilometers closer to the Sun than the Earth is.<a href="https://www.forbes.com/sites/startswithabang/2018/05/26/ask-ethan-can-we-build-a-sun-screen-to-combat-global-climate-change/#6807de0e1f00" target="_blank">read more</a></blockquote>
