Carbon dioxide levels rising fast in New Zealand too
Carbon dioxide levels are rising fast here, though not quite as fast as those recently reported for Hawaii.
Reports on CO2 data from Mauna Loa, Hawaii, state that the recent growth rate there is averaging 1.5 parts per million (ppm) per year, but the rate exceeded 2 ppm in both 2002 and 2003.
NIWA scientists have been measuring CO2 concentrations at Baring Head near Wellington since 1973.
