The United Nations is considering the risks of spraying “sulfate aerosols” above the earth’s surface to reduce global temperatures, according to a Reuters report.
Yesterday, a U.N. climate panel released a “code red” report that warned of “deadly heat waves, gargantuan hurricanes and other weather extremes” if drastic action isn’t taken quickly to stop man-made climate change.
According to the Intergovernmental Panel on Climate Change (IPCC), humans are “unequivocally” to blame, with U.N. Secretary-General António Guterres calling for a total end to the use of coal and fossil fuels.
According to a Reuters report on the issue, “controversial methods” of geoengineering are now being actively considered by the UN to limit and reverse global temperature increases.
“For example, humans could spray sulfate aerosols – tiny reflective particles – into the stratosphere 20 to 25 kilometers (12 to 16 miles) above the earth’s surface to reflect more sunlight back into space, which lowers global temperatures,” states the report.
However, using this method would create “uncertainty, moral issues (and) ethical issues” because “sulfate aerosols have the side effect of also lowering average precipitation.”
