The United Nations warns in a new report that humanity is doing far too little to limit global temperature rise to less than 1.5 degrees Celsius, a target of the 2015 Paris climate accord that would prevent the worst effects of catastrophic climate change. The U.N. found the rate of global carbon dioxide emissions rose last year for the first time in four years and is expected to climb again for 2018, with the world on pace to see a global rise of 3.2 degrees Celsius—or nearly 6 degrees Fahrenheit—by the end of the century. Such a rise would see devastating droughts, floods and extreme weather, with higher sea levels, crop failures, mass migration and global conflict. The U.N. is calling for new investments in renewable energy and for governments to replace subsidies on fossil fuels with taxes to discourage their use. The stark warning came ahead of U.N. climate talks set for Katowice, Poland, next month. Democracy Now! will broadcast from the talks during the week of December 10.
