Expect to hear a lot more about climate change in the news next week – and a lot about NIWA’s work underpinning the science that is signalling a warmer world right now and its effects in the future.
As part of CarbonWatch NZ, NIWA atmospheric scientist Dr Peter Sperlich is sending specially designed glass flasks on fortnightly trips from Wellington to Fiordland to collect air samples that are then analysed in Wellington, Taiwan and the US.
Top prizewinners: Blake Shepard, a Year 9 student from Rongotai College, won the $500 Royal Society of New Zealand Wellington Branch prize for the runner-up best overall exhibit with his project: “Is Cotton Rotten?”.
Everything from eating brownies made with bugs to a substitute for stickers on fruit has had a scientific eye cast over it ahead of this year’s NIWA Auckland Science and Technology Fair.
Frustration with buying fruit and vegetables that are never ready to eat prompted a 13-year-old Tauranga girl to a design a machine to help.Bay of Plenty Science Fair 2019 winner Anamaya Taylor.
A 12-year-old has taken on the most damaging honey bee parasite in the world to win the NIWA Waikato Science and Technology Fair.He compared the use of oxalic acid via cardboard strips and vaporisation on several beehives to determine which method was the most effective.
Two reports released today by NIWA and the Deep South National Science Challenge reveal new information about how many New Zealanders, how many buildings and how much infrastructure could be affected by extreme river and coastal flooding from storms and sea-level rise.
EQC, GNS Science and NIWA have joined forces to further develop world-leading natural hazards risk modelling for New Zealand. Mr Morgan said the new partnership will broaden use of RiskScape to include more government, council and infrastructure company users, enabling more people to get a better understanding of the potential costs of natural hazards.
That’s more than double the national standard of 50, with hourly concentrations peaking at 314 micrograms per cubic metre,” says project leader NIWA air quality scientist Dr Ian Longley.
“During summer, heatwave conditions scorched our seas for the second consecutive year, while several areas of the country suffered ongoing drought conditions, including Nelson-Tasman where prolonged wildfires occurred and a state of emergency was declared,” says NIWA meteorologist Ben Noll.
NIWA staff plunge into Evans Bay for their mid-winter's swim on 20 June 2019. NIWA forecaster Ben Noll says in the Far North, the winter solstice has about 4 hours and 45 minutes less daylight than the summer solstice, but in Southland the difference is more than 7 hours.
Understanding how the Antarctic oceans work is vital to predicting the world’s future climate and the implications of climate change for humankind and the planet.
LakeSPI surveys have been carried out on 12 Rotorua Te Arawa lakes (Ōkāreka, Ōkaro, Ōkataina, Rerewhakaaitu, Rotoehu, Rotokākahi, Rotomā, Rotomāhana, Rotoiti, Rotorua, Tarawera, and Tikitapu) since 2005 and NIWA freshwater ecologist Tracey Burton says she has seen positive and negative changes.
It’s a huge step forward for the leopard seal according to NIWA cetacean biologist Dr Krista Hupman, who largely attributes this success to Owha who made the Waitemata Harbour her home in 2012. NIWA Cetacean Biologist/Ecologist Dr Krista Hupman has helped getting leopard seals a new residential status in New Zealand waters.
The surface temperature of debris on the glacier was 21.6ᵒC when the photo was taken, while the surface temperatures of the lake and surrounding rock ranged from 3.5ᵒC to 30.2ᵒC [Image: Andrew Lorrey, NIWA].
Periods of extremely warm sea surface temperatures persisted for a prolonged period of time and extended thousands of kilometres [Photo: Dave Allen, NIWA]. For the past two summers, the Tasman Sea has experienced a marine heatwave, where periods of extremely warm sea surface temperatures persisted for a prolonged period of time and extended thousands of kilometres.
“Weather is such a vital element of a successful America’s Cup campaign,” said Emirates Team New Zealand CEO Grant Dalton.
Recent analysis by NIWA has shown that about 800,000 New Zealanders are exposed to fine particles in the air that exceed World Health Organisation guidelines every winter, the majority of which is due to home heating emissions.
Hotspots in the North Island are currently found in Aupouri Peninsula, interior Manawatu-Whanganui, and interior Hawke’s Bay. In the South Island, only subtle soil moisture changes were observed in the past week.
A weekly update describing soil moisture across the country to help assess whether severely to extremely dry conditions are occurring or imminent. Due to the anticipated rainfall amounts over the next week, soil moisture levels will likely increase at least slightly across much of the North Island.
A newly formed partnership between Asthma and Respiratory Foundation NZ (ARFNZ) and NIWA aims to provide the latest air quality research to over 700,000 people living with respiratory conditions in New Zealand.
However, hotspots remain in place across western Northland and Aupouri Peninsula, a small portion of central Waikato, southern Manawatu-Whanganui, and much of Wairarapa and southern Hawke’s Bay. In the South Island, soil moisture levels generally did not change significantly in the past week.
NIWA principal scientist climate Dr Brett Mullan says the high March temperatures were consistent with our warming climate and when seen in context with other warm months a clear trend was evident.
