Carbon dioxide (CO2) levels reported to have reached 400 ppm at Mauna Loa Observatory sent climate change activists like James Hansen, Al Gore, 350.org and Scientific American into a frenzy but Friends of Science say solar and ocean cycles are the main drivers of climate change, not CO2. With no global warming in 16 years despite a rise in CO2, the role of declining water vapor in upper atmosphere partially negates the heat-trapping effect of CO2.
