Sinking Global Warming: Is There a Reliable Way to Track Atmospheric Carbon Dioxide Levels?
The planet soaks up excess carbon dioxide via oceans, plants and soils, among other natural systems, locking away some of the greenhouse gases emitted by burning fossil fuels . In fact, every year these natural "sinks" absorb a larger and larger tonnage of emissions—but thanks to the increasing amount of CO 2 and other greenhouse gases dumped in the atmosphere by human activity, the proportion that is reabsorbed is beginning to dwindle, according to new studies.
