Harvard will conduct geoengineering experiments that will affect all of humanity, reports
A $ 20 million project at Harvard University. The United States assumes the spraying of aerosols into the Earth's stratosphere, and is the world's largest experiment on the use of chemtrails.
Two American scientists say they hope to solve the problem of global warming with the world's largest and most expensive solar geoengineering project. The experiments will begin in the next few weeks.
The goal of this program is to determine if aerosol technology can mimic the cooling effect of volcanic explosions in the atmosphere, in a desperate attempt to stem climate change.
"This is not the first or only university study," said Gernot Wagner, one of the co-founders of the project, "but it is by far the largest and most comprehensive."
The basic idea is that spraying certain types of particles into the stratosphere can help reflect more heat back into space, Technologyreview.com reports. Scientists believe it might work because nature already does it. Major volcanic eruptions in the past have thrown tens of millions of tons of sulfur dioxide into the sky, helping to reduce global temperatures in the following months.
Less clear is how accurately the technology could control temperatures around the world, what materials are best to use, and what environmental side effects might arise. Notably, previous volcanic eruptions have also reduced rainfall levels in some parts of the world, and sulfur dioxide is known to deplete the protective ozone layer.
Scientist Keith Koich emphasizes that it is too early to say whether any geoengineering technology should ever be deployed. But he has argued for many years that research must move forward to better understand its opportunities and dangers, as they can significantly reduce the risks of climate change. He stressed that the experiments will have negligible environmental impacts as they will involve no more than a kilogram of materials.

Critics of geoengineering argue that the climate system is too complex to intervene and environmental risks are too high, or that even talk of technological "fixes" could ease the pressure to cut greenhouse gas emissions.
Only two known geoengineering experiments have been conducted outdoors to date: researchers at the University of California, San Diego sprayed salt particles off the coast of California as part of the E-PEACE experiment in 2011, and scientists in Russia dispersed sulfate particles from a helicopter and car. in 2009. The SPICE experiment in the United Kingdom was quickly phased out in 2012 following public criticism and allegations of conflicts of interest after several scientists applied for a patent.
In an earlier interview, Jane Long, former deputy director of Lawrence Livermore National Laboratory, stressed that researchers advancing in geoengineering experiments need to pay great attention to ensuring proper public notice, data entry capabilities and proper oversight. But she said it was time to start seriously exploring the potential of the technology given the growing danger of climate change.
“We should have started this a decade ago,” she said. "It is very important to know as much as we can and it is important to know it as early as possible."
