UN Secretary-General Antonio Guterres issued a stark warning to world leaders at the COP29 climate summit in Baku, Azerbaijan, urging immediate action to prevent humanitarian disasters linked to climate change. Guterres emphasized that the window to limit global temperature rise to 1.5 degrees Celsius is closing. The summit saw about 200 nations participating, but notable leaders, including U.S. President Joe Biden and China’s Xi Jinping, were absent. An early agreement to establish a global carbon market was reached, but critics argue it was hastily made, undermining transparency and trust within the negotiations.
