The Earth is too hot and only getting hotter, according to governments and global bodies such as the United Nations; and the efforts to reduce carbon dioxide aren\u2019t having enough of an effect.<\/strong><\/p>\n

\u201cThe world is passing through the 1.5\u00b0C ceiling and is headed much higher unless steps are taken to affect Earth\u2019s energy imbalance,\u201d James Hansen, the previous director of the NASA Goddard Institute for Space Studies, warned<\/a> in January.<\/p>\n

Thus, to buy more time, on Feb. 28, scientists from NASA and the National Oceanic and Atmospheric Administration (NOAA) released a report<\/a> detailing a solution called \u201cintentional stratospheric dehydration,\u201d or in layman\u2019s terms, flying planeloads of ice to 58,000 feet and spraying ice particles into the upper atmosphere.<\/p>\n

\u201cIt\u2019s a very small effect,<\/strong>\u201d said lead author Joshua Schwarz<\/a>, a research physicist at NOAA\u2019s chemical sciences laboratory. \u201cPure water vapor doesn\u2019t readily form ice crystals. It helps to have a seed, a dust particle, for example, for ice to form around.<\/strong>\u201d<\/p>\n

The researchers report that by dispersing small particles, or what it calls ice nuclei, into areas of the atmosphere that are both \u201cvery cold and super-saturated with water vapor,\u201d water vapor in the atmosphere will \u201cfreeze-dry\u201d and rain out of the atmosphere as ice crystals, cooling the planet.<\/p>\n

The proposal is known as geoengineering\u2014and NASA and NOAA\u2019s joint plan is far from the only idea that\u2019s jumped from the pages of science fiction, \u00e0 la the 2013 Hollywood film \u201cSnowpiercer,\u201d to mainstream science.<\/p>\n

Istv\u00e1n Szapudi, an astronomer at the University of Hawaii Institute for Astronomy, has turned<\/a> to essentially geoengineering a giant parasol, or what he calls, a \u201ctethered solar shield\u201d to shield the Earth from a portion of the sun\u2019s energy.<\/p>\n

\u201cAny sunshield works by blocking a small fraction, circa 1\u20132 percent, of sunlight reaching Earth,<\/strong>\u201d Mr. Szapudi told The Epoch Times. \u201cThis is an almost undetectable amount by looking at the sun, but it would still cool the atmosphere to pre-industrial temperatures according to climate models.<\/p>\n

\u201cSpecifically, the tethered sun shield is a solution that is lighter, thus cheaper, by many orders than traditional designs.\u201d<\/p>\n

Technology entrepreneurs Luke Iseman and Andrew Song of Make Sunsets have already taken action and have been creating reflective, high-altitude clouds by releasing balloons full of sulfur dioxide (SO2) into the stratosphere, what they call stratospheric aerosol injection (SAI).<\/p>\n

\u201cWith climate change rapidly transforming our world, it\u2019s crucial that we prioritize action over words,<\/strong>\u201d Make Sunsets states<\/a> on its website.<\/p>\n

\u201cWe believe that SAI is the immediate, necessary solution to cool the planet and buy us time to transition to a more sustainable future.\u201d<\/p>\n

But scientists such as Christopher Essex, emeritus professor of applied mathematics and physics at the University of Western Ontario and the former director of its theoretical physics program, said CO2 isn\u2019t the driver of Earth\u2019s warmer temperature and that such geoengineering measures are \u201cextraordinarily dangerous.\u201d<\/p>\n

\u201cI used to run a climate panel for the World Federation of Scientists,\u201d he told The Epoch Times. \u201cAnd we had one session where we presented on exactly why geoengineering is extraordinarily dangerous. It\u2019s a crazy idea.\u201d<\/p>\n

Ian Clark, emeritus professor<\/a> for the Department of Earth and Environmental Sciences at the University of Ottawa, echoed Mr. Essex.<\/p>\n

\u201cGeoengineering the climate is a very scary prospect<\/strong>,\u201d he told The Epoch Times.<\/p>\n

\u201cIt\u2019s something that should be relegated to the fantasy realm and science fiction.\u201d<\/p>\n

The Oxford Geoengineering Programme defines<\/a> geoengineering as \u201cthe deliberate large-scale intervention in the Earth\u2019s natural systems to counteract climate change.\u201d<\/p>\n

Solar Shield<\/h2>\n

According to Mr. Szapudi, climate change is a looming threat, and greenhouse gases, such as CO2, are a driving cause of that threat.<\/p>\n

He published a report<\/a> on July 31, 2023, outlining his proposal for a tethered sun shield, what he calls solar radiation management.<\/p>\n

\u201cSolar radiation management\u00a0(SRM) is a geoengineering approach that aims to reduce the amount of solar radiation absorbed by the Earth to mitigate the effects of climate change<\/strong>,\u201d he wrote in his report.<\/p>\n

\u201cTwo strategies proposed for SRM involve adding dust or chemicals to the Earth\u2019s atmosphere to increase the reflected fraction of sunlight or reduce the incoming radiation from space with solar shades or dust.\u201d<\/p>\n

He\u2019s advocating for a sun shield because he believes it is less risky.<\/p>\n

When asked to comment on Mr. Essex\u2019s claim that geoengineering is \u201cextraordinarily dangerous,\u201d Mr. Szapudi said: \u201cSpace-based geoengineering, especially if it is modular and reversible in design, carries less risk than Earth-based SRM injecting dust or chemicals into the atmosphere, and [it is] vastly less risky than doing nothing.<\/p>\n

\u201cGiven what we know today and the known risks of climate change, a tethered sun shield near the L1 Lagrange point at 1.5 million kilometers from us would not present an obvious risk to Earth. The benefit is preventing and even reversing negative effects of climate change.\u201d<\/p>\n

NASA defines<\/a> Lagrange points as \u201cpositions in space where objects sent there tend to stay put\u201d because of oppositional gravitational forces. The agency has identified five such points.<\/p>\n

Mr. Szapudi acknowledged that there could be unknown risks and said that his proposal would need to undergo a more detailed scientific study, followed by a preliminary engineering study.<\/p>\n

\u201cSuch a study would specify the location, the design, the materials, etc., that are most suitable.<\/strong> At that point, a quantitative and thorough risk assessment can be done, and a decision can be made [on] whether to go ahead with the implementation,\u201d he said.<\/p>\n

\u201cIn general, any big project would go through many layers of risk, cost, and benefit analyses as the design shapes up, and any showstoppers identified would halt the project. Ultimately, only the most cost-effective and safest design, if any, will be implemented.\u201d<\/p>\n

But Mr. Essex, who built his first computer climate model in the 1970s and was<\/a> chairman of The Global Warming Policy Foundation\u2019s Academic Advisory Council, said part of the problem with a sun shield is that it looks at the climate from an engineering perspective instead of a scientific one.<\/p>\n

\u201cYou might be able to generate some plausible argument for defining the actual parasol and getting into space,\u201d he said. \u201cBut the part you don\u2019t understand is how climate will respond to it.<\/p>\n

\u201cBecause we\u2019ve been pushing this propaganda as being able to solve a problem, it starts to appear like an engineering problem where you can do trial and error and see if it works or doesn\u2019t work. <\/strong>But the climate problem is not an engineering problem; it\u2019s a fundamental scientific problem. … It\u2019s much more subtle and complex.\u201d<\/p>\n

Mr. Essex explained that solar radiation travels through the atmosphere, and while some believe that radiation causes warming at that point, that\u2019s not what\u2019s happening. Instead, the shortwave radiation hits the Earth, which heats the surface, and then the ground radiates that energy as longwave radiation into the atmosphere, increasing temperature.<\/p>\n

\u201cWith the parasol, they\u2019re trying to control shortwave radiation,\u201d Mr. Essex said. \u201cAnd it\u2019s an indirect way of controlling what goes on with the longwave, the infrared.<\/p>\n

\u201cPeople like to think the Earth is like a brick, and it\u2019s getting too hot, so we need to cool it down\u2014global boiling, that\u2019s the slogan\u2014well, that\u2019s ridiculous. It\u2019s just about hyping up anxiety and fear so the people will go along with things and not question what\u2019s going on.<\/p>\n

\u201cThere\u2019s so much going on in the atmosphere. It\u2019s complex, conductive, and turbulent.<\/strong>\u201d<\/p>\n

Balloons of Sulfur<\/h2>\n

Like a sun shield, reflective aerosols fall under the definition of solar radiation management. But unlike a sun shield, reflective aerosols aren\u2019t modular or immediately reversible.<\/p>\n
