Experts have warned that making artificial clouds to fight global warming could make things worse.
Scientists had come up with the idea of man-made clouds to reflect sunlight and heat back into space almost twenty years ago.
Health Effects of Global Warming
Greenhouse effect causes excessive heat to build up in the earth's atmosphere causing global warming and affects the environment and health.

It was proposed men can form clouds over the oceans by injecting salt spray into the air from a flotilla of sailing ships.
However, this concept of 'geoengineering' - deliberately altering the global climate - can actually hamper natural cloud formation over the coastal regions of the continents because of other pollutants from industrial activities.

UN Secretary General Ban ki-Moon on Monday called on world governments to work with the United Nations to vastly improve women's and children's health by 2015.
Professor Professor Ken Carslaw, of the University of Leeds, and his colleagues found, using a computer model, that it was hard to create a uniform layer of saltwater spray. Also, natural particles in the air, called aerosols, could interfere with the process.
"Our research suggests that attempts to generate brighter clouds via sea spray geoengineering would at best have only a tiny effect and could actually cause some clouds to become less bright," the Independent quoted him, as saying.
He added: "In some locations, the artificial spray particles may hinder natural drop formation and could have an opposite effect on climate to that intended. In practice, generating a uniform covering of reflective clouds over large regions of the world's oceans would be extremely challenging."

Global Fight Against Tuberculosis may be Helped by Body's Own Proteins
The re-emerging threat of tuberculosis (TB) may actually be countered with help from proteins from our bodies, scientists from Ohio are hoping.
