Another attention-seeking billionaire with too much time on his hands, dreaming up Hollywood-style schemes? A planned small-scale test is in the offing.

The Microsoft co-founder, who has donated about $50 billion to various charitable causes, considers climate change one of the most acute problems humanity is facing and has spearheaded several initiatives on research and development of clean energy, says Sputnik News.

A Bill Gates-backed project aims to stop climate change by dropping tonnes of chalk dust into the stratosphere, The Times reported.

According to the newspaper, the initiative funded by several private donors, including the Microsoft co-founder, will be the first serious attempt to deal with the issue of climate change by dimming the Sun.

Essentially, scientists will attempt drop chalk dust in the atmosphere hoping it will create sunshade that will reflect some of the Sun’s rays and heat back into space and dim those that get through, thus preventing our planet from getting warmer.

This summer scientists plan to launch a large balloon carrying 2 kg of chalk above the Swedish town Kiruna and then drop the chalk. Researchers will then monitor how it interacts with the atmosphere.

This information will be used to run simulation tests to see whether increasing the amount of chalk dust will help deal with the issue of climate change.

The scientists behind the project were inspired by the 1991 volcano eruption in the Philippines. Back then, Mount Pinatubo released an enormous ash cloud containing millions of particles of sulphur dioxide, which then formed into droplets of sulphuric acid that floated in the air for more than a year and acted as sunshade.

Scientists say that global temperatures went down 0.5 Celsius as a result of this.

Excuse for Politicians and Potential Impact on Weather System

Despite its popularity, the project has raised concerns among the scientific community.
