Earth’s temperature has been rising year by year and it is a serious threat to the population on the earth. Most developed countries are planning to keep this static and do not allow it to rise further. Both developed and developing countries are fighting Global Warming by planting trees and reducing the use of petroleum products.

In order to keep the earth’s temperature low and keep the planet cool, Bill Gates is supporting a project to “cool” the Earth by dimming sunlight. Scientists from Harvard University are doing research named “Stratospheric Controlled Disturbance Experiment” (SCoPEx in English) with the goal of accomplishing that sunlight is reflected outside our planet’s atmosphere.

To do this, tones of non-toxic calcium carbonate (CaCO3) would be sprayed into the atmosphere.

According to the project page, “SCoPEx is a research experiment to increase the understanding of stratospheric aerosols that may be significant for solar geo-engineering.” As a maneuvering test, the Scientists will first send a balloon with scientific equipment for exploring communications and operating systems. In the first stage it will not spray CaCO3.

 “We plan to launch an instrument package around 20 kilometres into the stratosphere using a high-altitude balloon. Once in situ, a modest amount of material (100g 2 kg) will be released to generate a disturbed air mass one kilometre long and one hundred metres wide. Then, using the same balloon, we’ll measure the changes in the disturbed air mass, such as changes in aerosol density, atmospheric chemistry, and light scattering,’ they add.
