'Fantasies': COP28 head says world can't 'unplug' existing energy system

Climate Change Conference, COP28, in Dubai said Sunday. "We cannot unplug the energy system of today before we build the new system of tomorrow. Much of international climate diplomacy revolves around the thorny issue of how and when to quit fossil fuels. But efforts since then to extend such a target to all fossil fuels have foundered, most recently at last month's G-20 summit in India. The goal of limiting warming to 1.5 degrees Celsius (2.7 degrees Fahrenheit) above preindustrial levels was set at the 2015 climate talks in Paris.
