A recent article centered around a idea proposed by a scientific aid to U.S. President Obama concerning a way to reverse the currents of global warming by sending up enough dust particles into the atmosphere to block out part of the sun’s radiation and cause global cooling. The idea, proposed by John Holdren, the President’s science advisor, would involve send up enormous amounts of pollution particles, possibly by a “controlled” nuclear blast, that would prevent the some of sun’s rays from reaching the earth, and result in cooler temperatures that would enable the Arctic and Antarctic ice caps to “repair themselves” by freezing over again.
Recent revelations that massive ice shelves are melting at both the extreme northern hemispheres, which would result in rising sea levels and eventual widespread ecological damage to world coastal areas, have caused some scientists to believe that the solution would be for the world to actually cool down by several degrees – even if this might result in severe winter weather to many areas and possibly even a “mini ice age” to countries such as Canada, Russia and others.
While the idea might possible work, at least from a temperature reduction standpoint, the long term effects of such an idea might prove even more damaging to life on earth than global warming itself. Professor Holdren believes that such an idea would reduce the amount of CO2 emissions that the present phenomenon of global warming is causing, creating the so-called “greenhouse effect”. But by blocking out the sun’s rays to kill some of the algae and other micro-organisms the contribute to this CO2 gas, it would also severely reduce the benefit of the sun’s life-giving warmth and light necessary for the survival of life itself – resulting in a nuclear winter effect as has been predicted to be the outcome of a nuclear war.
A number of climate theorists and paleontologists (those who study the earth’s earlier life forms) believe that the extinction of earlier life forms such as the dinosaurs were caused by severe nuclear winter-like atmospheric conditions caused by either a large asteroid striking the earth or by a number of large volcanoes erupting within a short period of time; thus preventing the sun’s rays from reaching the earth, and causing massive starvation to the creatures inhabiting the planet. A similar fate could be in store for us if we are deprived of the sun’s energy which gives life to all living things.
