Paris climate agreement faces challenges as US plans withdrawal

The Paris climate agreement, established in 2015, aims to limit global warming to below 2 degrees Celsius. It is a voluntary pact, requiring countries to submit emissions reduction plans every five years, but lacks mandatory enforcement. The United States is set to withdraw from the agreement, joining Iran, Libya, and Yemen as the only UN countries not participating. This withdrawal follows President Biden's rejoining the pact shortly after taking office. While the agreement has not fully prevented global warming, projections show a potential increase of 2.7 degrees Celsius. The U.S. withdrawal may affect its influence in climate negotiations and the global renewable energy market.
