Experts around the world One of the latest efforts in reducing global warming effects include using a yet-unproven sun-dimming technique, which researchers believe will reduce the effects of global warming on Earth.
CNN reports that the recent study on reducing the effects of global warming was conducted by a team at Harvard and Yale Universities. The team refers to the sun-dimming technique as a stratospheric aerosol injection, claiming it could reduce global warming by 50%.
Performing the stratospheric aerosol injection will require that Earth's lower atmosphere, known as the lower stratosphere, be sprayed with sulfates stretching across 12 miles. However, it's still unclear how the chemicals will be delivered
Nonexistent spacecraft to lift the chemicals
According to CNN, there is currently no aircraft in existence which will require the chemicals. However, the team behind the idea is enthusiastic about using balloons, saying "Developing a new, purpose-built tanker with substantial payload capabilities, neither technologically difficult nor prohibitively expensive."
The sun-dimming project could cost about $ 3.5 billion for the initial setup, plus an additional $ 2.25 billion for annual maintenance over 15 years. The price tag, according to the study, is considered "remarkably inexpensive."
Is it safe?
The researchers acknowledged that their technique is still tested and is still hypothetical. Many questions After all, hazardous chemicals in our environment have so far done more damage than good by ripping a massive hole in the ozone layer hole, for example.
Nevertheless, the team behind Environmental Research Letters remains optimistic about their idea Unfortunately, greenhouse gas emissions will still be an issue, even if the technique proves to be useful
"We make no judgment about the desirability of SAI," the study reads. "We simply show that a hypothetical deployment program commencing 15 years hence, while both highly uncertain and ambitious, would be really technically possible from an engineering perspective. It will also be remarkably inexpensive. "
Experts remain skeptical
Other experts are pretty skeptical about the idea, stating that this study is more like a major issue.
"From the point of view of climate economics, solar radiation management is still a much worse solution than greenhouse gas emissions: more expensive and much riskier than the long run," Philippe Thalmann of the École Polytechnique Fédérale de Lausanne, who works in the field of economics of climate change, told CNN
"The problem with engineering climate in this way is that it's only a temporary band-aid covering a problem that is persist essentially forever, actually hundreds of thousands of years for fossil fuel CO2 to finally go away naturally," David Archer of the Department of Geophysical Science at the University of Chicago
While the sun-dimming technique sounds like an innovative way to fight off global warming, we can not forget the cause of global warming, which is the high carbon dioxide and other greenhouse gas emissions. We can not blame our climate change problems while we continue to fill our atmosphere with dangerous gases.
