Earth’s vital signs are failing and to prevent planetary crash and burn, “we need…cooperation and political will”, UN Secretary General António Guterres said, challenging world leaders gathered in Dubai for COP28 to show real global climate leadership. The UN chief delivered his impassioned appeal at the high-level opening of the Global Climate Action Summit, which will see world leaders and Heads of State and Government taking centre stage for the next two days in the Al Waha Theatre in Dubai’s iconic Expo City.
