US special climate envoy John Kerry on Tuesday launched an international engagement plan to boost nuclear fusion, saying the emissions-free technology could become a vital tool in the fight against climate change. Kerry said the plan involved 35 nations and would focus on research and development, supply chain issues, and regulation, and safety. “There is potential in fusion to revolutionize our world,” Kerry told the COP28 climate summit in Dubai. Fusion, which powers the sun and other stars, can be replicated on Earth with heat and pressure using lasers or magnets to smash two light atoms into a denser one, releasing large amounts of energy.—Reuters
