China launched a global carbon dioxide monitoring satellite to understand climate change, hours after it lifted nearly a week-long red alert for the worst smog that engulfed about 40 cities in the country. The 620-kg satellite TanSat was put into orbit by Long March-2D rocket from Jiuquan Satellite Launch Centre in northwest China’s Gobi Desert early this morning.
