Chemtrails: A New Method to Slow Global Warming?

US geo engineers are about to splash out of the balloon a sun-reflecting chemical. An experiment in New Mexico attempts to cool the planet by spreading sulphate aerosols.

Two engineers from Harvard with a balloon, flying through Fort Sumner in New Mexico at an altitude of 24.384 meters, spatter into the atmosphere chemical particles that reflect solar radiation to artificially cool the planet. A natural solar geoengineering experiment aims to create a technology that mimics the cooling effects of volcanoes that exclude sulphates into the stratosphere and thus reduce the Earth's temperature. They want to do so using sulphated aerosols to reflect sunlight back into space.

David Keith, one of the scholars, argued that geoengineering can be an inexpensive method of slowing global warming, but other scientists warn that it could have unpredictable, disastrous consequences for Earth's climate systems and for food supply. Environmentalists are concerned that shifting geoengineering to climate change 'Plan B' will undermine efforts to reduce carbon emissions.

Keith, who manages the multi-million dollar geo-engineering research fund provided by Microsoft founder Bill Gates, has previously commissioned a study by an American airline commissioned by a large-scale deployment of solar geoengineering. His American experiment, conducted by American James Anderson, will take place within one year and involves the release of tens or hundreds of kilograms of particles to measure the impact on ozone chemistry and to test ways to spray droplets of sulphate aerosols into appropriate sizes.

Since the laboratory can not simulate the stratospheric complexity, Keith says the experiment will provide an opportunity to improve the modeling of how the ozone layer could be changed by much larger sulphate sprays. "The goal is not to change the climate, but to simply test micro-level processes," Keith said. "The direct risk is very small."

While the experiment does not harm the climate, environmentalists say that the significant global environmental risks of solar geoengineering have been identified by modeling and studying the impact of sulfur dust emitted by volcanoes. "Impacts include the potential for further damage to the ozone layer and rainfall, especially in tropical and subtropical areas - potentially threatening food supplies to billions of people," said Pat Mooney, Executive Director of the ETC Canadian Technology Watch. "It will do nothing to reduce the level of greenhouse gases in the atmosphere or to stop the acidification of the oceans. And solar geoengineering is likely to increase the risk of international climate-related conflicts - given that modeling has so far shown that it poses a greater risk to the southern hemisphere. "

The study, published last month, concluded that solar radiation management in North America and Northern Eurasia could reduce collisions with 15% and more than 20% in Central America.

Last fall British field the test of a balloon and a hose device that would draw water into the sky caused controversy. Government-sponsored project - Stratospheric Particulate Injection for Climate Engineering (Spice) - was abolished after a series of decrees and public protests by global NGOs, some arguing that the project is a "Trojan horse" that would open the door to widespread technology expansion. Keith said he had been opposed to Spice from the very beginning because he would not improve his knowledge of the risks or effectiveness of geoengineering, as opposed to his own experiment.

"I greet the British government for showing up and trying something," he said. "But I wish I could do it better because those who are against such experiments will see it as a victory and try to stop other experiments. "The Guardian understands that Keith plans to use Gates's fund to organize a meeting to study Spice lessons.
