Unfortunately it appears that life on this planet as we know it is seriously running out of time. Ice caps are melting faster than they are forming and this process is not only accelerating but irreversible. 2016 was the hottest year on record and every new year seems to break new records. Even worse, the severity and number of droughts and the number of forest fires keeps on increasing too.
Earth is already too hot and the average global temperature needs to be cooled down by 2 degrees Celsius ASAP. Global warming is already increasing droughts and terrible Co2-forming forest fires throughout the world leading to a possible runaway greenhouse effect releasing vast amounts of methane (a deadly greenhouse gas 20 times more potent than Co2) trapped in the melting permafrost in Siberia and other places around the Arctic Circle. This release of methane could rapidly send the average global temperature up another 5 degrees Celsius, and by 2030 this drastic increase in temperature could cause a mass extinction of nearly all biological life on this planet.
Unless the Sun miraculously cools down, the fastest way I know of to prevent this nightmare scenario from finishing us off is to redirect the orbit of asteroid Ceres (the smallest and closest dwarf planet that orbits between 2.9773 AU and 2.5577 AU or around 258 million miles from the Sun) into the stable L1 (langrangian) point one million miles away from Earth between Earth and the Sun so it would act as a massive space sunshade. Ceres is 587 miles (945 kilometers) in diameter, large enough to reduce the solar energy reaching the Earth by approximately 0.5% to 1%.
The relocation of a dwarf planet can be done gradually over time, using small explosions to nudge it back to within one million miles of Earth's orbit around the Sun to a point where it would constantly stay directly between the Earth and the Sun. However Ceres might still not be large enough to provide all the shade required to more fully cool the planet. Therefore we may actually need to add more asteroids as well, such as Vesta which has a diameter of 326 miles (525 kilometers) and could help shade the Sun by another 0.5%. A large number of many smaller asteroids can also be parked at this point with the advantage that they would be easier to move, but a much larger number of them would be required to create the same effect.
This project may be the only hope for the future of human life and all other life on Earth as we know it. We need to get NASA and other space agencies around the world to devise a plan to make this possible. The Sun is also going to start heating up very slightly anyway over the centuries ahead as it begins to exhaust its supplies of hydrogen, therefore making this project doubly important. If this idea sounds crazy enough, then the idea of allowing all the ice caps to melt and the oceans to rise would be even more insane. All the coastal cities around the world will flood if this catastrophe is allowed to happen. All life on Earth could go extinct as the planet effectively moves out of the Solar System's habitable zone and into the hot zone.
