These measurements, supplemented by analyses of air bubbles trapped in ice core samples, show unequivocally that atmospheric CO2 has increased from a pre-industrial level of 277 ppm in 1750 to present day concentrations that are approaching 390 ppm.

The project will bring insights into Earth's climate cycle through the analysis of air bubbles trapped in ice.

Not exact matches

The paper, «Reconstruction of past atmospheric CO2 concentrations by ice core analysis», acknowledges that, due to impurities, liquid water can exist as low as -50 deg C. Diffusion of CO2 into this water, due to its far higher solubility than nitrogen and oxygen, will partially deplete the CO2 from trapped air bubbles.

These estimates resulted from studies of air bubbles recovered in ice cores from deep within Antarctica, Greenland and other glaciers, as well as chemical analyses of coral samples from beneath the sea.
