dr. andrews: north america does take up a lot of co2. one reason that we've taken up a lot of co2, historically, is that when the eastern part of north america was settled, a lot of forests were cleared for agriculture. and those have been regrowing over the past 100, 150, or 200 years. and so those forests have taken a lot of carbon dioxide out of the atmosphere, but they're nearing maturity, and so they probably won't be such a strong net sink for atmospheric carbon dioxide in the future. narrator: by increasing the number of tall towers, noaa scientists will enhance their ability to understand the rate that natural ecosystems are absorbing or releasing carbon dioxide. dr. andrews: we're really trying to develop a sampling network that will allow us to kind of keep our finger on the pulse of the biosphere continuously. so something that's sustainable and that we can use to monitor net carbon dioxide emissions for many years. narrator: taken together, the programs at noaa's global monitoring division have revealed not only how quickly g
