Scientist to use Limestone could control global warming

These particles are highly reflective and would reflect a right amount of sunlight back to space and in essence, cool the planet.

Global warming has become a scary realization today. It is perceived to be one of the biggest threats today. So much that over 80 countries met in Paris to create a treaty promising to reduce greenhouse gasses releases.

A group of scientists has used the volcano as a model to create an alternative way to control the temperature. A volcano releases sulfate gasses when it erupts. These gasses help reflect sunlight and reduce the temperature of the earth.

But the scientists acknowledged that they cannot use the Sulfate gasses because they are highly toxic. However, they found an alternative in the form of calcite particles.

This technique of altering the atmosphere is called Geoengineering. They intend to add calcite molecules around 15 miles above the ground. These particles are highly reflective and would reflect a right amount of sunlight back to space and in essence, cool the planet.

"We can be certain there would be unintended consequences," said David Keith, professor of applied physics and public policy at Harvard. "What they would be nobody has looked at in a serious way because of this taboo against research."

But some sections argue that altering with the atmosphere would spell disaster. Mother Nature would push back with dire consequences. The first argument is that the foreign particles are heavier than atmospheric gasses and would sink. This would lead to the ocean and rainforest surfaces being covered by the smog.
