Hitting books: Sci-Fi strategies may be needed to prevent climate change
The temperature of the earth is too high. Unless we can get our planet to stop the heating trends, and soon, our species continue to be here very much in danger. Of course, we have implemented countless climate change remediation schemes in the past few decades but in fact the fixed that our chances of window to overcome this problem are quickly closed. It might be time in the near future so we stop farting with half steps and removing a big weapon of the saying, namely geoengineering and terrororation.

If everything fails, can we calm the earth using improved extreme technology? In the worst scenario, protecting billions of people will take unprecedented engineering achievements. Geoengineering aims to overcome climate change using intentional and large-scale technology interventions. Think of our own planet terraforming. To be honest, most of these ideas come directly from the science fiction page. But many get serious scientific attention. By 2030, we must know which one is our best bet.
Geoengineering comes in two flavors. The first option is blocking the sun to reach the earth. The second is to suck greenhouse gases from the atmosphere. Both are high-risk interventions insanely in complex systems.
There are several ways to block sunlight, starting from the cosmic level. Establishing a giant sunlight between the earth and the sun will do work well, with potentially stopping around 2 percent of the heat coming in from the sun. The numbers have been colored. We will need hundreds of thousands of sunlight 10 square feet (1 meter-square) weighing around 20 million tons (18 million metric tons). In total, it will cost some trillion dollars and last around 50 years. But this does not help sea acidification, because carbon dioxide will still build in the atmosphere. If we continue to emit, even if we block the incoming sun radiation, the ocean will be steady more acidic – one of the main causes of past mass extinction. In addition to costs and technical challenges, giant sunlight tends to bring unexpected consequences: for example, change the weather pattern throughout the world.
Maybe the most widely discussed geoengineering solution is to throw millions of tons of small small particles to the atmosphere to reflect heat back into space. We know this successful. Every major volcanic eruption issued ash to the upper atmosphere. It has a measurable effect on the climate. When Mount Pinatubo erupted in the Philippines in 1991, the planet was cooled a little for several years after the initial eruption, but this impact was short-lived because these particles disappeared in the upper atmosphere in several years. The scale of this type of intervention must be very large: around 3.3 to 5.5 million tons (3 to 5 million metric tons) sulfur is issued every year.
Cloud Seeding or Whitening is another option. Rummaging the seats can throw salt particles into the atmosphere that helps the formation of the cloud. More clouds will reflect more heat back into space and may cool the planet. This idea can be used locally to protect coral reefs, for example. However, on a global scale, this will require a broad fleet of autonomous vessels that stab the ocean forever.
