Due to what happened last year in a deal called the "Paris Climate Deal", the entire world is going to fight towards lower the carbon emissions, as an international effort. However recent reports have been coming in saying that one can do that while reducing global temperatures.

This process is knowna as Geoengineering, Solar Geoingeering to be more precise. It goes towards nearly the most molecular level and it will introduce light-reflecting particles. These particles could be let go near the stratosphere (the outer most atmosphere) of planet earth.

These light reflecting particles are simply going to reflect the rays of the sun back into space. Since they are reflective naturally they will not take any energy while doing so. This will ultimately make the planet cooler.

However this idea has been around for decades, it was just too risky. Particle News says that scientists have found out a way to make this idea safe. When a volcano erupts it usually sends this sulfuric aerosol into the atmosphere.

This aerosol then does the same thing as what a light reflecting particle would do. It also cools the atmosphere and water vapor then it rains around the volcano. This is a natural "putting out the fire" mechanism. However Sulfur is bad for earth and humans.

Science Alert mentions that Sulfur would destroy the Ozone more. Therefore scientists are saying that perhaps they could create an aerosol that has the same properties as the sulfuric one but it is made out of a material which would never react with the atmosphere.

There are many promising propisitions going about which are getting the attention of even the news. However this idea is still very new and will take a large amount of time as well as a global participation for it to work.

Luckily both of these factors are somewhat present and so this could solve many things.
