El Nino Blamed for Observed Record High Carbon Dioxide in Atmosphere

Carbon Dioxide Increase in Atmosphere Sets New Record
The annual growth rate of atmospheric carbon dioxide measured at the Mauna Loa Observatory in Hawaii jumped by 3.05 parts per million during 2015, the largest year-to-year increase in 56 years of research, according to the U.S. National Oceanic and Atmospheric Administration (NOAA).

The development is significant because Mauna Loa Observatory is the oldest continuous atmospheric measurement station in the world and is widely regarded as a benchmark site in the World Meteorological Organization’s Global Atmosphere Watch network.
