The United Nations has taken a historic step in the fight against climate change by adopting a new agreement that calls for the world to transition away from fossil fuels. The agreement, which was gaveled in by COP28 President Sultan al-Jaber, has been met with both praise and criticism, and is the latest in a series of steps taken by the U.N. to combat climate change. The agreement is seen as a necessary step in the fight against climate change, though there are worries that there are too many loopholes in the agreement.
