A meeting of the Group of 20 major economies (G20) in India on Saturday failed to reach a consensus on phasing out fossil fuel emissions after objections from some producing countries. Scientists and activists are furious that international bodies are dragging their feet on steps to limit global warming, even as extreme weather from China to the United States underscores the climate crisis facing the world. Together, G20 members account for more than three-quarters of global emissions and gross domestic product, and the group's cumulative efforts to decarbonize are key to the global fight against climate change.
