Proposing to cover the Sun to cope with global warming

This plan sounds crazy, but it is completely feasible, and even science has proven that it can reduce the Earth's temperature that way! What prevents this plan?

The Conference on Climate Change in Paris has proposed many solutions to reduce the amount of carbon that we emit into the environment. The layer of CO ₂ covering the Earth is a blanket that keeps warm for our planet, but by "adding our own" blankets to the Earth, we still have to face many more problems. global warming.

In recent years, global warming is reaching alarming levels, polar ice sheets are melting and sea water is rising. The consequences are gradually approaching the threshold of each country.

One of the measures that can be used is "returning" part of the solar energy, bringing them back into space. This method is called Solar Radiation Management (SRM) , and this is a method of using technology to combat the most viable global warming up to this point.

Global warming is reaching an alarming level.

For example, we can spray seawater into the atmosphere, creating new clouds, this is a very effective way to counter the solar heat generated. Some other plans refer to placing mirrors outside the universe, leaving them in place where the gravity between the Earth and the Sun is balanced. This amount of cosmic mirrors can reflect 2% of sunlight falling, but this plan faces a huge financial barrier.

Perhaps that solution can be used immediately is to spray small molecules to the stratosphere (about 20km in the air). In order to maximize the amount of sunlight that can be reflected, these molecules must have a surface of at least 0.5 micrometers.

We already know that volcanic dust from large eruptions reduces the planet's temperature. Typically, the 1991 eruption of Pinatubo volcano in the Philippines. About 10 tons of sulfur dioxide is released into the atmosphere, they quickly form droplets of sulfuric acid in the stratosphere. These particles reflect the sun and reduce the temperature of the Earth. Within a year after the eruption of the Pinatubo volcano, Earth's temperature dropped by about 0.4 degrees C and then returned to normal shortly afterwards.

We now have such a "crazy" technology: it is possible to pump titanium dioxide molecules into the atmosphere with large taps, lifting them up with a helium balloon. But this plan quickly went bankrupt because of a funny reason but very reasonable: what if this plan was successful, it doesn't turn out we don't need to cut emissions anymore?

Many problems arise in plans to use science to intervene in climate issues. The most important issue is that we only have one Earth to test, if the plan is "clean", what will we do? A late apology can't buy us a No. 2 Earth to continue testing. The method must be done, the method must be implemented in the long term right before our eyes right now is to reduce emissions to the environment immediately.

Is taking the cloud cover the sun is the solution?

It can be said that this "solar cover" plan will hold us back a little longer to find more solutions. But it absolutely cannot be a long-term solution or a definitive solution to the climate problems we face. Protect the Earth before everything is too late.
