Arrowtown may be known for its picturesque autumn scenery, but in winter this tiny Central Otago town has a problem.
Hotspots in the North Island are currently found in Aupouri Peninsula, interior Manawatu-Whanganui, and interior Hawke’s Bay. South Island hotspots are currently found in interior Marlborough, a small area near Christchurch, coastal southern Canterbury, and a portion of Stewart Island.
Part of the world’s largest ice shelf is melting 10 times faster than the overall average and solar-heated waters beneath the ice shelf are to blame, NIWA research has found.
The latest state of the environment report released today provides New Zealanders with clear evidence that our climate, freshwater and marine systems are changing, says NIWA.
Across the North Island, soil moisture levels generally changed little during the past week. In the South Island, increases were observed along most of the West Coast, interior Otago, and Marlborough Sounds, while decreases occurred in Stewart Island.
A newly formed partnership between Asthma and Respiratory Foundation NZ and NIWA aims to provide the latest air quality research to over 700,000 people living with respiratory conditions in New Zealand.
Across the North Island, soil moisture levels decreased in big parts of the island during the past week due to meagre rainfall. In the South Island, soil moisture decreases were observed across much of the island.
An increase in soil moisture in many areas across the North Island, including Northland, Auckland, Waikato, eastern Bay of Plenty, Gisborne, and Taranaki. No significant change in the South Island. Outlook is for low to moderate rainfall, countrywide.
NIWA today released its March Climate Summary which confirms temperatures during the first month of autumn were at record highs in many places.
Hotspots continue to be found across a large part of Northland, Auckland, northern Waikato, and interior Bay of Plenty, as well as central Manawatu-Whanganui and Napier south to Wairarapa.
