Carbon dioxide keeps building up in the air,” said Scripps scientist Ralph Keeling, who maintains the longest continuous record of atmospheric carbon dioxide on Earth. Prior to the onset of the Industrial Revolution, carbon dioxide levels had fluctuated over the millennia but had never exceeded 300 parts per million. Ralph Keeling and his late father Charles David Keeling have kept carbon dioxide (CO2) measurements at the Mauna Loa Observatory in Hawaii since 1958. Carbon dioxide is called a greenhouse gas for its ability to trap solar radiation and keep it confined to the atmosphere. The burning of the oil, gas and coal for energy releases greenhouse gases such as carbon dioxide and methane.
