The United States and China, the world's top two carbon emitters, have agreed to collaborate on addressing global warming by significantly increasing their investment in renewable energy sources such as wind and solar power to reduce their reliance on fossil fuels.

A United Nations-backed report reveals that major fossil fuel-producing countries, including the United States, Russia, and Saudi Arabia, are on course to produce twice the amount of fossil fuels that exceed critical global warming thresholds by the end of this decade.

Extreme weather events such as heatwaves, floods, and hurricanes can disrupt production and supply chains.
