TEXTV US considers 'sun blocking' to coai the Earth lt sounds like something out of a sci-fi novel, but some researchers want to coai the earth by reflecting sunlight back into space. Sun blocking' technologies - also known as solar radiation modification (SRM) - could theoretically coai down the earth by reflecting sunlight back into space. One idea involves pumping sun-blocking particles into the upper atmosphere. This process of 'stratospheric aerosol injection' would involve planes spraying an aerosol like sulfur dioxide into the stratosphere. This mist of particles would reflect lhe sun back upwards, shading lhe earth. The method has already worked - although accidentally. When Mount Pinatubo in lhe Philippines erupted in 1991, it released thousands of tons of sulfur dioxide. The global temperature temporarily dropped by 0.5ºC. ln September 2022, researchers at Yale University argued that lhe injection method could hypothetically refreeze lhe peles. A White House report published last Friday confirms that the US is open to researching SRM. "A programme of research into lhe scientific and societal implications of solar radiation modification (SRM) would enable better-informed de.cisions about lhe potential risks and benefits of SRM as a component. of climate policy, alongside lhe foundational elements •of greenhouse gas emissions mitigation and adaptation:f'· it says. However, the repor! also clarifies lha! no decisioi:1': has been made to "establish a comprehensive research ·!"programme focused on solar radiation modification." ln February, several news outlets reported that lhe UN wanted to ,'explore' this technique. This could give the impressiori.,that lhe organisation had approved sun blocking as a viablé' toai to fight climate change. Unfortunately for tech enthusiasts, this is not the case. The UN Environmental Program's recent repor! into SRM concludes lha! it is not currently a realistic ar wise plan. "UNEP concurs with lhe panei lha!, ai present, large-scale, ar operational deployment of SRM technologies is not necessary, viable, prudent ar sufficiently safe, given lhe limited scientific understanding and uncertainty about lhe potential impacts and unintended consequences," says UNEP's Chief Scientist Andrea Hinwood. "The review concludes that SRM cannot replace reducing greenhouse gas emissions." Nonetheless, lhe body doesn't rule out the method altogether, with lhe repor! concluding that their assessment of the technique "may change should climate actions remain insufficient".
