While most of the CO2 emitted by far is the result of natural phenomena — namely respiration and decomposition, most attention has centered on the three to four percent related to human activities — burning of fossil fuels, deforestation.

They looked at the potential long - term consequences of oceans ever richer in dissolved carbon dioxide, as humans burn ever more fossil fuels and emit greenhouse gases that continue to warm the atmosphere.
