FARGO — The continuous measurement of atmospheric carbon dioxide at the Mauna Loa Observatory in Hawaii has been interrupted because a lava flow from the now-erupting volcano has cut power to the site. The high mountain's location is rocky and far-removed from any contamination from industry or plant life. It has been measuring the gas most associated with human-caused Climate Change for over 60 years, during which time carbon dioxide has increased from around 310 parts per million (ppm) to more than 420 ppm.

It is this chemical change in our atmosphere that is the origin of the concern about the changing climate and rising sea level. The interruption of data from the Mauna Loa observatory will have only limited impact on climate research as there are numerous collaborative sites in operation around the world. Data was also interrupted during a volcanic eruption in 1984 and also by a temporary lack of funding in the 1960s.

John Wheeler is Chief Meteorologist for WDAY, a position he has had since May of 1985. Wheeler grew up in the South, in Louisiana and Alabama, and cites his family's move to the Midwest as important to developing his fascination with weather and climate. Wheeler lived in Wisconsin and Iowa as a teenager. He attended Iowa State University and achieved a B.S. degree in Meteorology in 1984. Wheeler worked about a year at WOI-TV in central Iowa before moving to Fargo and WDAY..
