To Fight Global Warming

World is facing major problem in the form of climate change. People must be aware of the impact they generate in this earth. Planting trees is the order of the day but I don’t think people are realizing the importance of it. Recently scientists have come up with more information regarding this matter.  I hope you find it interesting. The threat of devastating climate change is now so great that some scientists say it is time to investigate a Plan B - geo-engineering on a planetary scale. Such methods of altering the world’s climate may become necessary, they say, unless emissions of greenhouse gases fall within five years. Ideas that were once the realm of science fiction - such as creating artificial trees to absorb carbon dioxide, or reflecting sunlight away from the Earth. One method is to make clouds brighter - especially in the Pacific where the ocean temperature has great influence on world climate.

If these clouds can be brightened so you increase the sunlight reflected it looks as though that could be enough to prevent most of the effects of global warming. The crystals would act as nuclei around which water vapor could condense and thus raise the clouds’ reflective power, bouncing more of the sun’s energy back into space. Critics warn that although such schemes might lower temperatures swiftly, they must be maintained for long periods and the side-effects are unknown.
