Preventing Global Warming through Geoengineering

Most scientists are in unanimous agreement that global warming is a real threat to Earth’s ecosystem. All sorts of plans have been proposed on how to put a halt to the planet’s steadily rising temperature.

Researchers are now turning to solar geoengineering as a possible solution. The plan involves adding aerosol to the atmosphere, which will help to intersperse the sun’s solar energy and minimize its effects when it reaches Earth’s surface. The idea is to block out about two percent of the sun’s rays.

Like most plans, this one is not without its side effects. It is believed that putting such a plan into action could potentially whiten the sky during daylight hours, though there is no danger of having a milkier sky.

The research was headed by Ben Kravitz and Ken Caldeira and is published in the periodical for the American Geophysical Union.

Carbon dioxide is released into the atmosphere everyday through the use of coal and gas from vehicles and factories. This is causing the planet to heat up. Normally, an eruption from a volcano will counteract this effect. An eruption releases particles into the stratosphere and creates a natural shield from sun rays, though the Earth will reheat once the particles thin out. With geoengineering, the idea is to continuously release the particles into the stratosphere through artificial means.

Geoengineering has been tested on small scale environment models. While the plan seems promising, the sky will take on a lighter shade of blue. The sky will be a tad hazier and whiter with a bit of an afterglow from the sun’s appearance.

The human race has already inflicted an irreversible deal of damage to its only home in the last 50 years alone. Though geoengineering is an artificial solution, it may give the planet a much needed lifeline.
