UN chief, Gore, others give heated warnings in climate talks SHARM EL-SHEIKH, Egypt (AP) — With the world on “a highway to climate hell with our foot on the accelerator,″ the United Nations chief on Monday told dozens of leaders to ”cooperate or perish,” singling out the two biggest polluting countries, China and the United States.Barbados Prime Minister Mia Mottley called for a massive overhaul of international development loans and a 10% tax on fossil fuel companies, which she said made “$200 billion in profits in the last three months.” “I don’t need to repeat the horror and the devastation wrecked upon this Earth over the course of the last 12 months since we met in Glasgow,” Mottley said.“Whether the apocalyptic floods in Pakistan or the heat waves from Europe to China or indeed in the last few days in my own region, the devastation caused in Belize by Tropical Storm Lisa or the torrential floods a few days ago in St. Lucia.” Ahead of this year’s conference, known as COP27, leaders and experts have been ringing alarm bells that time is running out to avert catastrophic rises in temperature.We are at the beginning of a long, challenging and urgent transformation.” More than 100 world leaders will speak over the next days at the gathering in Egypt, most from developing countries demanding greater accountability from the richest, most polluting nations.Much of their focus will be on telling their stories of devastation by climate disasters, including a speech Tuesday by Prime Minister Shahbaz Sharif of Pakistan, where summer floods caused at least $40 billion in damage and displaced millions of people."
