It looks like scientists are willing to try anything to stop climate change. A new idea suggests dimming the sun to deal with global warming. This means spraying chemicals into the Earth’s atmosphere to block out UV rays. The process could significantly cut down on global warming. However, it might pose a completely new danger to future generations.
The idea has been proposed by researchers from Harvard and Yale in an effort to combat climate change. The technique known as stratospheric aerosol injection (SAI) requires spraying large amounts of sulfate particles into the Earth’s lower stratosphere. The chemicals would be injected into altitudes as high as 12 miles.
Scientists believe that the technique can effectively cut the effects of climate change in half.
But how will scientists manage to introduce these sun-dimming chemicals into the atmosphere? The sulfates will reportedly be delivered by specially designed high-altitude aircraft, balloons or large naval-style guns. In fact, the team is currently “developing a new, purpose-built tanker with ‘substantial payload capabilities’ and would neither be ‘technologically difficult nor prohibitively expensive.'”
Although it sounds like a plausible idea, the report also stressed that the technique is purely hypothetical at the moment. It may take several years before the SAI system can actually be developed.
The ambitious project might cut the effects of global warming down by half but it could also be costly. According to the report, the cost of launching the SAI system is estimated at $3.5 billion. In addition to that, there will be running costs of $2.25 billion every year.
Although SAI can stop UV rays, it can’t do anything about rising greenhouse gas emissions.
Not all scientists are convinced by the idea. David Archer of the Department of Geophysical Science at the University of Chicago says “it’s only a temporary Band-Aid covering a problem that will persist essentially forever.”
“It will be tempting to continue to procrastinate on cleaning up our energy system, but we’d be leaving the planet on a form of life-support. If a future generation failed to pay their climate bill they would get all of our warming all at once.”
First Image From The Surface Of Mars Revealed After NASA’s InSight Successfully Landed
It has been a long curiosity as to what Mars actually looks like. Images of the planet from afar have been shared to the public multiple times, but nobody really knows what the surface of the Red Planet really looks like until now.
NASA has successfully landed a probe on the surface of Mars. After a nearly seven-month journey and gripping landing sequence, NASA’s InSight lander has already returned its first image of the Martian surface.
China Creates Artificial Sun That Is Hotter Than The Real One
It seems that you can build anything right now, even the sun. A new report revealed that China has built an “artificial sun," which is designed to replicate the real. The reactor is a part of a project to turn hydrogen into green energy.
China’s “artificial sun” has reached a temperature of 180 million ºF (100 million C) with a heating power of 10 megawatts, according to scientists at the Chinese Academy of Sciences’ Institute of Plasma Physics, where the experiment was conducted. The device called the Experimental Advanced Superconducting Tokamak (EAST) is built to harness the energy of nuclear fusion, the same process that powers stars.
No, Not All of Earth’s Water Came From Asteroids, According To New Research
The belief that water came from asteroids is a “blind spot,” according to these experts.
Contrary to what most scientists would tell you, it looks like not all of our planet's water came from asteroid matetials after all. One recent research in the United States is now challenging that, claiming our science books may have not been entirely accurate all along.
It has always been believed that Earth's water came from asteroids since it was discovered that ocean and asteroidal samples contain similar ratio of deuterium to normal hydrogen. We've mostly been taught this "fact" in school but those science textbooks may have to be rewritten soon enough.
