CH4
A
more efficient at absorbing heat but spends less time in atmosphere than CO2
6

are humans the cause?

sharp increase from 1950s in anthropogenic CO2 emissions
- cooling of upper atmosphere, heating of lower
- winter warming faster than summer and nights faster than days

- less heat escaping to space
