WASHINGTON, Dhu-AlHijjah 9, 1436, September 23, 2015, SPA -- U.S. President Barack Obama said Wednesday that he hopes major countries agree to “aggressive enough targets” to cut carbon emissions at climate talks in Paris later this year, but said that any deal will fall short of what is needed to slow climate change. “I’m less concerned about the precise number, because let’s stipulate right now, whatever various country targets are, it’s still going to fall short of what the science requires,” Obama said in an interview with Rolling Stone magazine. According to scientists, global warming needs to be limited to 2 degrees Celsius to avoid devastating droughts and rising sea levels. Countries are submitting pledges to cut emissions ahead of the U.N. climate summit. Those pledges so far are estimated to limit warming to 3 degrees Celsius. -- SPA 00:18 LOCAL TIME 21:18 GMT www.spa.gov.sa/w
