Scientists disagree about the global causes of geoengineering
Scientists around the world are splitting in two camps with one camp to support the opinion that geoengineering may cause serious damage to the earth if try to use it and the other one to support the opposite of those great fears.
For example, scientists believe the opinion of serious damage on the earth have the argument that through geoengineering some sunlight could be diverted away from the earth by using airplanes or rockets to disperse sulfur compounds into the outer atmosphere on a daily basis, copying the results of big volcanic explosions. Of course that may sounds paranoid argument but in science many situations seem paranoid.
From the other side, scientists believe that geo-engineering may cause opposite results to different countries and they argued that the real effects of such a program would be difficult to predict, producing local advantages and disadvantages even if overall food production did rise.
The scientists can’t predict that any better strategy could be discovered that would give advantages all of countries on the earth. In opposite, they predict serious problems between countries that are enveloped from sea, like islands and countries like Holland, and those countries that weather is warm and hot all the year in tropical zone because if the tropical countries face an increase in temperatures, their agriculture will have serious damages.
The final conclusion about geoengineering is that still is a sector that remains inside deep fog and needs much more research from scientists in the future. At the moment scientists may think that will be much more appropriate to follow the safest way off limiting emissions now rather than risking future generations a damage that may not be at all easy repair.
