Global warming will continue to melt mountain snow caps and the polar ice, causing extreme weather across the planet. These calamities will become more regular, and more furious. Corrective action by all countries is urgently required for the safety of the planet and all life on it. Are we already too late?
The International Energy Agency in May released its Net Zero by 2050: A Roadmap for the Global Energy Sector. It says a net-zero pathway requires annual additions of solar photovoltaic cells to reach 630 gigawatts by 2030 and of wind power to reach 390 GWs, quadrupling the level in 2020 and accounting for almost 70 percent of electricity generation globally.
