Why is the Earth getting warmer? If you look into it, the process is basically the following:
1. The Sun emits some of its radiations towards the Earth;
2. Those radiations enter the Earth’s atmosphere;
3. When those radiations (infra-red) bounce the planet’s surface they go back to space or are reflected back to the surface, due to greenhouse gases, making Earth hotter.
Therefore, there are two possible fronts to consider if we want to stop global warming:
1. Diminish the amount of greenhouse gases;
2. Diminish the amount of infra-red radiation absorbed.
Yes, that’s right. Scientists are trying to block part of sun rays, in order to lower the temperature in the atmosphere. One of the solutions proposed by the scientific community was the placement of giant mirrors surrounding the planet. That way, some sunlight wouldn’t pierce atmosphere, thus fighting against global warming. Just imagine the change it would be for someone who would go to outer space and watch Earth, not as a blue planet, but as a shining planet.
These kinds of bioengineering projects at a world-wide scale have been considered absurd, but now, with a rapidly increasing world crisis coming our way, they are starting to be considered as a possible solution. From blocking sun power with oversized mirrors to releasing iron particles in oceans to enhance algae’s carbon dioxide absorption, or even release sea spray into the air, so that clouds may gain thickness and reflect more sunlight, bio-engineering projects should be studied for they can make a difference between life and death for many human beings as well as other creatures in our planet.
We made this mess and it’s up to us to stop it.

I agree with you completely, i think that since it was us humans that destroyed our planet than it should be us that should clean it up.
ReplyDeleteThe video was a good idea and really interested the viewer.

In my opinion cover the Earth with this reflected materials it is not so far the best solution for the problem. But I think it is the solution to cover the problem. I ask myself how it is possible to cover ten percent of the Earth with reflected materials. I must say that people's attitudes has to change!
ReplyDeleteThese ideas don't sound that bad when we are already feeling the consequences of global warming but they still look rediculously over-proportioned. I don't the situation is so bad that we need to resort to them. For now, the main focus should be makeing clean energy the only energy world wide.
