Today, I was standing at the lights intersection waiting for light to turn green, when I looked up and just thought this area of intersection can easily be roofed. Well why would it need a roof, because people on motorbike who stop by at red light knows hot hot the sun is. But think about if we put a giant roof on a large city or even larger than that, So I though of Sun shield, I Google it and found their are so many discussion/research already in progress. I found one of explainer of Geo-engineering . Click on drop down menu to see other strategies.
Doing so is almost like controlling the weather, which means controlling weather of one region would affect the weather of other region that might not be in your home territory. However, Summers are just too hot to bear. If you have got any idea don't waste a single second to post it here, its a topic of serious discussion. Nobody wants to walk out in hot sun drop sweat , exposing skin to different types of diseases that can be caused by sun's radiation. Its like a punishment.
