aThe researchers then analyzed how much carbon dioxide was in the atmosphere above each of these sites over time. “Less carbon dioxide has remained in the atmosphere, relative to the amount of fossil fuel emissions, today compared to 50 years ago,” Tans said. Even including the effects of ...

Fresh, young black carbon tends to be resistant to water. Over time, the particles age and become more hygroscopic, or able to absorb water from the air. But when does black carbon start absorbing water, act as cloud nuclei, and remove itself from the atmosphere?
Molecule for molecule, many of these other gases cause more warming than carbon dioxide does—in the case of methane, 120 times more warming the moment it reaches the atmosphere. But methane doesn’t stay around as long as carbon dioxide. Ultimately, what really matters isn’t the amount of...
pathways it takes from emission source to the atmosphere or carbon reservoirs such as oceans and forests. Combined with satellite observations such as those from NASA’s recently launched OCO-2, computer models will help scientists better understand the processes that drive carbon dioxide concentrations...
So what happens is, when we burn this carbon—OK, it doesn't really release a whole lot, compared to the amount that’s already there in the atmosphere, but it adds to the pool.And over years it accumulates. Think of the atmosphere as a big bathtub:It’s basically already filled to...
Carbon dioxide plays a key role in plant life and helps keep the earth warm. Increasing levels of carbon dioxide in the atmosphere, though, are linked to global warming.
