Despite the small size of this year’s ozone hole, scientists cannot yet say whether this ozone hole season marks the start of a sustained recovery of the Antarctic ozone layer or just year-to-year variation.
NIWA is looking at the long-term effects of motorways and wood smoke on air quality. Scientists are assessing the impacts of Auckland’s southern motorway on air quality in a surrounding neighbourhood. They are doing this to understand more about the health effects of air pollution.
The HIAPER jet recently flew very low over NIWA’s atmospheric climate research station at Lauder. The international mission is taking a slice of the atmosphere, so scientists can learn more about greenhouse gases globally.
A paper to be published in the prestigious science journal, Nature, this week offers a rare piece of good news on climate change but signals that the atmosphere may be more variable than previously suspected.
