The CWR Survival Guides to Avoiding Atlantis
By China Water Risk 24 November, 2020
Seas are rising faster than we think – how will 20 APAC cities that generate US$5.7trn of GDP be affected?
Hong Kong, 23rd November 2020 – CWR releases a series of “survival guides” to avoid Atlantis in its Coastal Capital Threat Series, which benchmarks risks for 20 coastal capitals and economic hubs in APAC from Tokyo to Sydney. According to CWR, urban real estate equivalent to 59 Singapores will be underwater without serious adaptation measures if we continue with business-as-usual. And that’s just for 20 coastal cities.
Seas are rising faster than we think so CWR has curated a “survival guide” series of five reports to help avoid this dire future. The five reports include an overview of the latest science on rising seas; a ground-breaking CWR APACCT 20 Index to benchmark risks; physical threats levels of 20 APAC cities; what governments are or are not doing to protect from existential threats; analyses of sovereign and clustered financial risks from GDP and trade to bank loans; as well as next steps and to-do lists for multiple stakeholders to waterproof APAC.
Running out of time to protect APAC cities
We think we have more time to avoid Atlantis, but we don’t. We will likely hit 1.5°C of warming by 2030. Reaching this 70 years earlier than the intended Paris Agreement target date of 2100 means we will feel the impact of rising seas sooner. As it is, we are already 1.1°C warmer than the pre-industrial period.
“Bangkok & Jakarta could be permanently submerged by 1.94m & 2.37m respectively by 2050…
Instead of 1m, ice experts now say that sea level rise as high as 3m is plausible by 2100. Unfortunately, as many cities are sinking and face typhoons across APAC, coastal threats will be felt sooner. According to CWR, ASEAN cities like Bangkok and Jakarta could be permanently submerged by 1.94m and 2.37m respectively by 2050.
Elsewhere in typhoon prone North Asia, both Hong Kong and Tokyo could see storm tides of 5.5m+ today if typhoons arrive at high tide.
… storm tides plus rising seas could reach 10m+ by 2100 for Hong Kong”
Costs from storms are set to balloon – just seven typhoons between 2017 and 2019 cost APAC US$60bn, yet CWR estimates that storm tides plus rising seas could reach 10m+ by 2100 in their worst-case scenarios for Hong Kong.
According to CWR’s reports, a person standing in front of the AIA, Hong Kong Club, HSBC, Mandarin Oriental or Standard Chartered buildings in the city’s Central financial district will be hit by waves as high as 5.69m.
We’re not prepared: APAC impacts are severe & clustered
“If we are not prepared, APAC’s coastal capitals will become the new Atlantis. Impacts are severe as they are clustered – around 3m of SLR will paralyse trade-reliant APAC economies and wipe out millions of homes and jobs”, warned Debra Tan, the Head of CWR. “Just 20 coastal cities in our CWR APACCT 20 Index drive around a quarter of global sea and air cargo volumes; yet at 1.5°C we’d lock-in the loss of 20 ports and 12 airports that serve these cities. This clearly puts the recently inked RCEP trade deal at risk” she adds.
Managing coastal threats is integral to avoiding Atlantis. As part of its survival guide, CWR worked with the financial sector to develop the CWR APACCT 20 Index for 20 coastal capitals and economic hubs. Over 100 finance professionals from chairs/directors of bank boards to credit/equity research analysts plus financial industry associations, asset owners and financial regulators helped build this inaugural index which not only benchmarks physical coastal threats but also government adaptation action to protect cities as it can reduce risks.
“At 4°C 100mn people will lose their homes, urban real estate equivalent to 59 Singapores will be underwater…
…plus all 23 ports and 23 out of 25 airports will be permanently submerged…for just 20 coastal cities”
The risk snapshot CWR provides is sobering. CWR’s index shows that rising seas will cause 28 million people to lose their homes, urban real estate equivalent to 22 Singapores will be underwater. And this is under the best-case scenario of 1.5°C, which we will lock-in in 10 years’ time.
Inaction means our current climate path of 3°C-5°C will send us headlong into a dire future – swathes of APAC will be underwater – the 4°C CWR APACCT 20 Index shows that over 100mn people will lose their homes, urban real estate equivalent to 59 Singapores will be underwater plus all 23 ports and 23 out of 25 airports will be permanently submerged without serious adaptation measures. And that’s just for 20 coastal cities.
“These sea level rise impacts were supposed to hit us a few hundred years in the future but now we may feel the locked-in impacts of 1.5°C as early as 2100, and for 4°C by 2200.” said Tan. Latest research released this year indicates that Greenland and Antarctica are losing ice 6x faster than they were in the 1990s plus our oceans have warmed at an alarming rate, equivalent to dropping 5 Hiroshima bombs per second into the ocean for the last 25 years. Both accelerate rising seas. Given this grim future, “APAC must move to implement no-regret adaptation for locked-in impacts at 1.5°C plus commit and fast-track carbon neutrality to avoid 4°C” urged Tan.
No-sense strategies: Governments not taking action despite high exposure warrant sovereign re-rating
“CWR’s index rankings reveal unexpected behaviour – not all governments are taking action to protect their cities despite high exposure to coastal threats”
Yet, CWR’s index rankings reveal unexpected behaviour – not all governments are taking action to protect their cities despite high exposure to coastal threats. At the bottom, at No.20, is Taipei in the 1.5°C CWR index; and Macao in the 4°C CWR index. Surprisingly, other cities with lacklustre adaptation despite high vulnerability are Hong Kong and Tokyo.
At the top, Singapore leads the pack: No.1 in both 1.5°C and 4°C CWR APACCT 20 Index rankings – it’s spending over SGD100bn on adaptation including raising critical infrastructure by 5m. Shanghai, Shenzhen and Guangzhou, are all vulnerable but their adaptation efforts including reinforcing and building sea walls see their rankings materially improve. Jakarta’s extreme plans of moving its administrative capital plus building sea walls and polders see it to the Top 5.
CWR’s analysis also reveals that not all cities from the same country are taking the same amount of action despite significant GDP at risk. If this continues, the region will be in for a hard landing. As Dharisha Mirando, lead author of the series stated “The high concentration of financial risks is concerning. In APAC, people, assets and GDP are clustered in coastal capitals and key cities – the 20 APAC cities in our index generate US$5.7trn of GDP per annum, this is greater than the combined GDP of Germany and Canada.”
“Our analysis has led us to put Japan, Hong Kong, Macao and Taiwan on our watchlist”
Mirando further cautioned that “These cities drive their national/territorial GDP – around 20% plus more for Tokyo, Seoul, Sydney, Auckland, Bangkok, Manila and Taipei to 100% for Hong Kong, Singapore and Macao. Such levels have implications for sovereign credit risk. Our analysis has led us to put Japan, Hong Kong, Macao and Taiwan on our watchlist. These governments should step up action to protect their cities, especially since they can afford to.”
Highly concentrated risks could trigger financial collapse
Risks expand beyond GDP and trade. CWR’s reports reveal bank loan books, markets and pension funds are also clustered and exposed to coastal threats. Central banks and financial regulators are taking action to address climate risks and credit rating agencies have also started to warn of coastal threat implications for sovereigns. But chronic risk assessments and inclusion of coastal threats in valuations have yet to manifest. This missing chunk of chronic risks results in an incomplete APAC risk snapshot that perpetuates a vicious cycle – capital continues to be deployed to vulnerable locations while ongoing investments in carbon intensive industries further exacerbates vulnerability.
“Sooner or later, we must bite the bullet and discount terminal values… This is finance 101; not natural capital accounting”
Banks are acting with recent carbon neutrality pledges but CWR says they are not acting fast enough. “The longer we ignore chronic tail risks, the worse it becomes. Sooner or later, we must bite the bullet and discount terminal values – the permanent overhang from rising seas effectively turns the valuations of all vulnerable assets from “freehold” into “leasehold”. This is finance 101; not natural capital accounting. Don’t just prioritise carbon transition risks – banks must start to assess and spread physical coastal threats plus ensure capital adequacy” said ex-banker Tan.
Governments & central banks must act to waterproof APAC
Indeed, the statistics in CWR’s reports are compelling as they are shocking; a much needed urgent wake up call to action. With so much at stake, CWR hopes that all stakeholders use their 3-step survival guide – Step 1: Get on top of existential threats; Step 2: Assess exposure; and Step 3: Take action to waterproof APAC with tailored to-do lists for different stakeholders. Sounds simple right? As Tan summarised “It’s time for finance and governments to make sensible plans to ensure that APAC is ready and can survive capital threats and systemic shocks ahead. Together we must waterproof APAC to avoid Atlantis. The alternative is unthinkable”.
Recommended next steps:
- Read “Waterproofing APAC to Avoid Atlantis” for an overview of what you need to know about the changing risk landscape, how to assess threat exposure and next steps;
- Use the CWR APACCT 20 Index to gauge relative coastal risks by seeing index rankings of 20 APAC cities for various scenarios; See who the 100+ finance experts were that inputted into the development of the index and what they had to say in “Avoiding Atlantis: CWR APACCT 20 Index”;
- Assess absolute risk exposure to each of the 20 APAC cities using the “CWR APACCT 20 Index City Factsheets”;
- Use our How-to-Guides in “Changing Risk Landscapes: Coastal Threats To Central Banks” to conduct in-depth analysis of SLR, subsidence and storm risks for hotspots;
- Assess what governments are doing to protect cities in hotspots compared to what’s at risk in terms of GDP “Sovereigns at Risk: APAC Capital Threats”;
- Understand actions by financial regulators as they will act to avoid the lethal cocktail of 1) no-sense climate strategies; 2) over-valuation of all assets in vulnerable cities; and 3) concentrated financial risk, which can trigger financial collapse;
- Supplement the analysis with other recommended tools – the CWR APACCT 20 Index was created to plug a gap in the existing toolbox, but this does not mean the other tools are not useful; and
- Follow our to-do list for all stakeholders as well as the more specific next steps for central banks & financial regulators, asset owners & asset managers, banks, and governments.
