The concentration of heat-trapping carbon dioxide in the atmosphere has climbed 40 percent over the last century. And, the new study reports, the Earth will continue to warm to dangerous levels. 

Steven Sherwood is a climate scientist at Australia's Centre of Excellence for Climate System Science and lead author of the report. He says the prediction of a 4-degree celsius warming is based on the role of water vapor in cloud formation.

“What we see in the observations is that when air picks up water vapor from the ocean surface and rises up, it often only rises a few kilometers before it begins its descent back to the surface. And those shorter trajectories turn out to be crucial.” 

Sherwood says under this scenario, in which clouds do not form, the Earth would absorb more sunlight. Rosanne Skirble VOA News Washington.
