Ideile surprinzătoare ale lui David Keith privind schimbările climatice

Injecting particles into the upper atmosphere could cool the planet quickly and at a fraction of global GDP, just as volcanic eruptions have temporarily done in the past. Although this approach could offset rising CO2 levels almost instantly, it introduces side effects like potential ozone depletion and moral hazards that could undermine emissions reduction efforts. As the pace of climate change accelerates and traditional solutions stall, society must openly debate the risks and ethics of radical interventions now possible through science.
