Paris climate agreement aims to reduce global warming but lacks enforcement measures

The Paris climate agreement, established in 2015, is a voluntary pact aimed at reducing global warming. The U.S. is set to withdraw, joining Iran, Libya, and Yemen as the only UN countries not part of the agreement. The pact requires countries to submit emissions reduction plans every five years, but there are no penalties for failing to meet targets. The U.S. has committed to reducing emissions by up to two-thirds by 2035. Rich countries are expected to assist poorer nations with climate change, with a goal of $300 billion annually. The U.S. disputes the binding nature of this target and has historically provided less aid than its share.
