Air Quality

NIWA scientists say concentrations of ozone high in the atmosphere are projected to increase.

This is good news for the ozone hole over the South Pole.  However, modelling shows that, by the year 2100, ozone in the lower atmosphere could actually be a problem for New Zealand and for much of the Southern Hemisphere.

The statement made by NIWA Principal Scientist, Dr Keith Lassey in a TV3 news story about methane (22 Dec 2009) is correct.

The concentration of methane in the atmosphere is rising, according to measurements made by NIWA.

NIWA has today released measurements from its globally significant Baring Head station showing that southern hemisphere atmospheric methane increased by 0.7% over the two-year period 2007–08. While this increase may not sound like much, it is about 35 times more than all the methane produced by New Zealand livestock each year.
