After COP 15 - what to do to make the Earth less hot?

As a result of the failure of the International Conference on Climate Change in Copenhagen (COP 15), research agencies have returned to find ways to implement technical initiatives to reduce the atmospheric temperature of the atmosphere. land.

Volcanoes spray sulfur into the atmosphere

1- Spread sulfate to the atmosphere

Based on the practice of the Pinatubo volcano explosion (Philippines, 1991), sulfur dust bounced into the atmosphere, causing the Earth's temperature to drop by 0.5 ^° C two years later. But the side effects must be solved: without increasing the acidity in the ocean, the ozone hole does not expand and does not create more clouds in the sky.

2- Planting food crops with slippery leaves

The area of ​​growing food crops is huge. Selecting, breeding or genetically modifying the leaves of these trees is more slippery and glossy, reflecting more sunlight back into space, making the ground cooler.

3- Create lots of white clouds

The cool ground is due to the cloud cover and is even cooler when the clouds become whiter, reflecting more solar radiation. It is possible to create white clouds by firing up the air at the center of the nucleus. Salt vapor rising from sea water is the most available.

4- Shading the Earth

The idea is bold and dangerous: shoot millions of millions of small discs away from the ground to create a shadow to cover the globe.

5- Planting artificial forests

Another costly measure is the planting of artificial tree forests that can strongly absorb CO2. Just planting 100,000 trees of this type can suck up the pollutant emissions of the whole UK.

Snow ice Alps (Switzerland) melted too early (June 2008) compared to before.This phenomenon will cause millions of people to lack drinking water

6- Iron fertilizing the oceans

In order to help marine plant plankton grow stronger, more photosynthesis, thereby absorbing more CO2 emissions. Experiments have begun, but people fear that in the long run will increase the proportion of acid in the ocean.

7. Carbon capture and burial

This technique has been mentioned very early, in order to transfer CO ₂ emissions from coal-fired power plants to solids and then bury them in abandoned mines. Hopefully this can be deployed massively from 2015.

8- Plant algae on high-rise buildings

To exploit the photosynthesis ability of algae to absorb CO2 emissions in cities, transformed into fuel to reduce oil dependence. Algae are grown in PBR (photo-bioreactor) tubes, covering the outside of buildings.
