• Resumen

  • This article reports on the expected world-wide growth of carbon dioxide levels. World carbon dioxide levels are estimated to grow 75 to 150 percent in the next century, and the productivity of green plants was expected to increase as well. Furthermore, high CO2 led to algae that had higher chlorophyll content but were smaller in size and often very weak under normal conditions. Although photosynthesis picked up, the algae also respired more oxygen, emitting more CO2 than normal in the process. The findings appear in the September 30 Nature, the same day Russia signed the Kyoto Protocol to cut emissions. Once ratified by the Russian parliament, the protocol becomes an international treaty.
