Nasa has launched a mission dedicated to measuring carbon dioxide (CO2) from space.

The US space agency is to launch today a satellite that tracks atmospheric carbon dioxide, a leading greenhouse gas that contributes to global warming.

The US space agency (Nasa) will make a second attempt on Tuesday to put a high-resolution carbon dioxide observatory in orbit.

The first satellite was destroyed on launch in 2009.

Five years after a NASA satellite to track carbon dioxide plunged into the ocean after liftoff, the space agency is launching another almost exactly like it — this time on a different rocket.

According to new data released this week, May 2014 is officially the warmest May in recorded history.

Sea level rise is threatening the majority of Nasa's launch pads and multi-billion dollar complexes famous for training astronauts and launching historic missions to space, scientists said on Tuesd

The collapse of the West Antarctic Ice Sheet, which holds enough water to raise global seas by several feet, has begun.

A large section of the mighty West Antarctica ice sheet has begun falling apart and its continued melting now appears to be unstoppable, two groups of scientists reported on Monday.
