NZ sea level rising twice as fast (Newsroom)

The first project to incorporate climate projections with New Zealand's unique tectonics raises red flags for planners and policymakers.

We knew that there would be, over time, and so the programme is designed in a way to be able to cope with that.” “It’s going to be important to get that right if it’s going to achieve what we need it to achieve. SeaRise combines satellite measurements of vertical land movement with global projections for sea-level rise from the latest Intergovernmental Panel on Climate Change report. We’re dealing with a system that’s changing and the rate at which it’s changing is increasing.” “Things like the vertical land movement data are really helpful in terms of breaking down how it might look at different points along the coastline. Parts of the country that are rising, like Stewart Island and the Bay of Plenty, would experience much slower sea-level rise. That’s knowledge, that's power, we can plan for that right now and we must plan for that right now,” Naish said. Much of the country could cross that first 30-centimetre threshold in a matter of decades, the SeaRise research found. Two decades later, the coastline could disappear under between 57 and 61 centimetres of sea-level rise, depending on whether global emissions decline rapidly or continue to rise. The results will be crucial as local and central government start to prepare for the impacts of climate change. Levy, who also leads environment and climate work at GNS Science, said relatively small changes in sea level can have an outsized impact on the likelihood and severity of extreme events. Parts of the North Island are sinking by nearly a centimetre each year.

On 2 May 2022 the NZ SeaRise: Te Tai Pari O Aotearoa programme will release location specific sea-level rise projections out to the year 2300 for every 2 km ...

NZ SeaRise is a five-year research programme funded by the Ministry for Business, Innovation and Employment Endeavour Fund. It brings together 30 local and international experts from Te Herenga Waka-Victoria University of Wellington, GNS Science, NIWA, University of Otago and the Antarctic Science Platform to improve projections of sea-level rise in Aotearoa New Zealand. The sea-level projection and mapping tool was developed by Takiwā, a Māori-owned data management and analytics platform. The finance and insurance sector have already been asking for the data – in part driven by the Task Force on Climate Related Financial Disclosures reporting requirements that need to be met by 2024,” said Dr Levy. “We know that global sea-level rise of 25-30 cm by 2060 is baked in and unavoidable regardless of our future emissions pathway. These small but continuous changes add up, and in areas that are going down (subsiding) the annual rate of sea-level rise can double. “Twenty years ago we thought sea-level rise was like pouring water into a bathtub – if you put more water in, it rises uniformly around the world. However, local sea-level rise around the coast of Aotearoa is also affected by up and down movements of our land.

Climate Change Minister James Shaw said the findings were "sobering" and the Government’s first plan to cut emissions in every part of New Zealand, would be published later this month. Joint Otago Regional and Dunedin City Councils’ South Dunedin Future group programme manager Jonathan Rowe welcomed the new information and said it would feed into many aspects of the councils’ work, particularly that relating to the South Dunedin programme which was considering climate change adaptation options. "We have estimated future sea levels for 7434 sites around our coastline.

With seas rising, who will pay for our most vulnerable coastal ... (The Spinoff)

Insurance companies aren't going to pay for homes made unliveable by sea level rises, so where should homeowners turn? Good question, writes Tom Logan.

But this still leaves the complex financial and ethical question of what happens to existing property owners. This guidance is not mandatory, however, and many councils do not have the resources or expertise to take a risk-based approach. This would ensure the premiums paid by coastal residents stayed in the local economy to support them. When the chance of damage rises beyond what an insurance company is prepared to bear, it withdraws. Domestic and international precedent suggests the central government might compensate some property owners. The latest research tells us coastal properties will start to lose insurance cover within the next 10 years, if not sooner.

Kiwis can now see how sea level rise will affect them (1 News)

New maps - developed for communities and planners - show how much and how fast the sea level will rise along their stretch of coast.

"I think it's true - for a long time New Zealanders have thought about climate change as a problem that's happening at some point in the future to someone else, somewhere else in the world. "We know that the temperature has already increased by about a degree over the last century. So we do have to adapt to the effects of climate change that have been caused by the pollution we've already put into the atmosphere." Their aim is to improve projections of sea level rise in New Zealand and new data they released on Monday shows sea levels are rising twice as fast as previously thought in some parts of the country. Many parts of Auckland will see the sea level rise 30-50% faster than what was previously thought. The maps - developed for communities and planners - show how much and how fast the sea level will rise along their stretch of coast.

Cyber attack hits website showing projected sea level rise (RNZ)

A new website designed to show how New Zealand's coastline will be affected by rising sea levels and land subsidence, has been hit by a cyber attack.

''We have estimated future sea levels for 7434 sites around our coastline. Rowe said for South Dunedin, the new data confirmed previous guidance, that further sea level rise of 24cm-35cm was predicted by 2050-60, and up to 112cm by 2100, depending on global emissions. ORC operations general manager Gavin Palmer said the information would also feed into flood protection planning to mitigate the impacts of sea level rise in other parts of coastal Otago, such as the Clutha Delta and the Taieri Plain. Joint Otago Regional and Dunedin City Councils' South Dunedin Future group programme manager Jonathan Rowe welcomed the new information and said it would feed into many aspects of the councils' work, particularly that relating to the South Dunedin programme which was considering climate change adaptation options. Naish said continuous small and large seismic events were adding up to cause subsidence in many parts of New Zealand, and the new projections showed the annual rate of sea level rise could double. The NZ SeaRise website shows location-specific sea level rise projections to the year 2300, for every 2km of the coast of New Zealand.

Cyberattack targets sea level rise website on the day of launch (Stuff.co.nz)

The website was being hit a thousand times a second in the morning before the site was brought down by a cyber attack.

Our bustling capital newsroom published nearly 3800 stories in the past year on this city, wind, hail, horizontal rain or shine. Though sea levels may be rising universally due to climate change, the land itself could be rising or sinking over time depending on the geological characteristics of the area, so the net sea level rise at specific points on the coast may vary wildly. He said a lot New Zealanders wanted to know location-specific sea level rise information but couldn’t get it from the website on the day of the launch. Naish said the website was being hit a thousand times a second in the morning and their website developers at Takiwā noticed a lot of overseas IP addresses attempting to access the site. A new website showing detailed projections of sea level rise around New Zealand was targeted by a cyberattack on its first day live. Cyberattack targets sea level rise website on the day of launch

The cost that needs to be borne won’t fall on one party.” “You are going to see the impacts of quite damaging sea level rise much sooner than we thought. “We have less time to act,” Naish said. Yes, it is a bit terrifying but there is still time and I think that is the way to look at it.” NZ SeaRise co-leader Tim Naish, a professor at Wellington’s Victoria University, said while the global sea level is expected to rise about 0.5 metres (19.8 inches) by 2100, for substantial parts of New Zealand it could be closer to 1 metre (39.4 inches) because the land is sinking at the same time. While the global sea level is expected to rise 5 metres by 2100, for large parts of New Zealand, it could be 1 metre because the land is sinking too.

New Zealand: Cyberattack hits 'SeaRise' website to show sharp rise ... (Republic World)

New Zealand website 'SeaRise' was hit by a cyberattack, leading to false reports showing sea levels rising twice as fast as previously thought.

"Property owners, councils, infrastructure providers, and others need to know how sea level will change in the coming decades so that they can consider how risks associated with flooding, erosion, and rising groundwater will shift." Meanwhile, project co-leader and GNS Science associate professor Richard Levy stated that the team had linked vertical land movement data with climate-driven sea-level rise in order to provide locally-relevant sea level data. "We're trying to get it back up and running," he added.

It could be described as a perfect storm - rising sea levels and cities that are slowly sinking.

People know that in a disaster that the government steps in." "Part of the reason the market is ignoring the risk is because they're not seeing any intervention by government.
