Government scientists have proposed a novel idea to potentially cool the overheating Earth by adjusting the upper atmosphere to make it drier. This concept aims to reduce the concentration of water vapor, a natural greenhouse gas that traps heat, similar to carbon dioxide. The new proposal highlights innovative thinking on climate intervention that could complement other strategies in addressing global warming. In related news, U.S. Climate Envoy John Kerry reflects on the latest international climate negotiations, emphasizing the urgency to phase out oil, gas, and coal, known as the root cause of global warming. Kerry's reflections underline the need for timely and comprehensive agreements in climate talks to expedite global efforts in reducing greenhouse gas emissions and promoting sustainable practices.
