Just seen this in an article in S China Morning Post, re the East Lantau Metropolis = Lantau Tomorrow Vision plan:
Charles Ng Wang-wai, chair professor of civil and environmental engineering at Hong Kong University of Science and Technology, said concerns about rising sea levels due to climate change were nothing short of “excessive” and “absurd”.
He pointed to data from the UN-backed Intergovernmental Panel on Climate Change, which indicated that Hong Kong sea levels would rise 0.6 metres by the middle of this century and surpass one metre by the end of the century.
“These are not major considerations in my opinion,” Ng said. “If a two-metre sea wall isn’t high enough, then you build one that’s four metres high. What’s the big deal?”
I commented:
Prof Charles Ng seems unduly confident re sea level rise prediction by IPCC.
Compare in California; scientists saying should prepare for sea level rise of around 3 metres by 2100, and factor this into plans for infrastructure.
Also evidently clueless about storm surges, even after Mangkhut, along with waves on top driven by hurricane force winds - the kind of waves in Typhoon Jebi that flooded Osaka airport, which engineers had "guaranteed" against flooding by building defensive wall. Engineers' hubris is no real match for power of nature, especially as climate change drives stronger storms; especially if only content to look at best case scenarios.
Note that IPCC may be underestimating sea level rise; various reports suggest ice is melting faster than expected. See, for instance:
Experts say the IPCC underestimated future sea level rise: A new study surveys 90 sea level rise experts, who say sea level rise this century will exceed IPCC projections

Reclamation dangerous in a time of climate changing
Communities in vulnerable areas such as north Norfolk and south Devon have already seen these devastating events play out, with homes left inundated with water and cliff-top buildings sent crashing into the waves.
Experts have warned that this will only get worse as the effects of climate change play out across the country in coming decades, and many coastal areas will be left uninhabitable."
