First direct observation of carbon dioxide's increasing greenhouse effect at Earth's surface

Scientists have observed an increase in carbon dioxide's greenhouse effect at Earth's surface for the first time. They measured atmospheric carbon dioxide's increasing capacity to absorb thermal radiation emitted from Earth's surface over an 11-year period at two locations in North America. They attributed this upward trend to rising carbon dioxide levels from fossil fuel emissions. 

"We see, for the first time in the field, the amplification of the greenhouse effect because there's more CO2 in the atmosphere to absorb what the Earth emits in response to incoming solar radiation," says Daniel Feldman, a scientist in Berkeley Lab's Earth Sciences Division and lead author of the Nature paper.

The measurements also enabled the scientists to detect, for the first time, the influence of photosynthesis on the balance of energy at the surface. They found that CO2-attributed radiative forcing dipped in the spring as flourishing photosynthetic activity pulled more of the greenhouse gas from the air.
