Protesters joined a worldwide wave of marches Saturday demanding leaders craft a pact to avert a climate catastrophe when they gather in a still-shaken Paris. Some 150 leaders including US President Barack Obama, China's Xi Jinping, India's Narendra Modi and Russian President Vladimir Putin will attend the start of the Paris conference, which is tasked with reaching the first truly universal climate pact, binding 195 nations to new emission limits from 2020. The goal is to limit average global warming to two degrees Celsius (3.6 degrees Fahrenheit), perhaps even less, over pre-Industrial Revolution levels by curbing fossil fuel emissions blamed for climate change.
