We seldom think about sea level rising. What was it ? A few milimeters in a hundred years, according to Trump. And of course he is wrong.
But we don't. We put it away in some dark corner.
But on the other side of the planet, it's a very different story.
Take your time for this one.

"Jun 11, 2025
Rising Tides, Shifting Powers delves into the poignant reality of Pacific islanders grappling with the existential threat of climate change and the complex geopolitics involving the United States and China. The episode opens with Millicent Barty, a climate activist and entrepreneur, whose daily life exemplifies the immediate dangers faced by Pacific communities. As sea levels rise, their cultural heritage is at risk, mirroring the precarious future of the entire island nation.
Simultaneously, Suluafi Brianna Fruean, a Pacific Climate Warrior, represents the voice of young Pacific Islanders on a global platform. She campaigns for the urgent need for climate action for the Pacific.
The episode weaves together these personal stories with the broader themes of superpower competition, revealing how the Pacific islands, while small and geographically distant, are at the forefront of major global issues. The finale of Rising Tides, Shifting Powers leaves viewers reflecting on the resilience of Pacific peoples and the critical role they play in shaping their destiny amid rising environmental and geopolitical challenges.
Fight for the Pacific, a four-part series, showcases the Pacific’s critical transformation into a battleground of global power. This series captures the high-stakes rivalry between the US and China as they vie for dominance in a region pivotal to global stability. The series frames the Pacific not just as a battleground for superpowers, but also as a region with its own unique challenges and aspirations."

Oh, right! Insolation was higher.
Thanks, hadn't thought of insolation at all.

What do you think, +4m higher than today in Thailand translate to on the global scale?

Miller 2020 and Rohling 2021 put the global sealevel for MIS6 at -65m and -67m or thereabouts compared to today.
Rodbell's 2022 tropical glaciers were re-growing and already exceeded their pre-industrial state.
And Loulerque's 2008 methane was decreasing, also suggesting a cooling in the tropics.

So bar glacial contribution to global #sealevel, if sealevel did rise in 190ka in Thailand's Southern Malay Peninsula, earth quake activity is a very good suspect.
Especially considering how the 2004 earth quake uplifted some land parts by 1,20m and subsided others by 65cm in the direct neighborhood.

Hong et al investigate sediments in a submerged/buried valley in southeastern South Korea to investigate sea level changes. They conclude that the penultimate glacial maximum (MIS 6) sea level lowstand was about 10 m lower than the Last Glacial Maximum.

Leknettip et al investigate some fossil beach ridges on the Malay Peninsula in southern Thailand. Surprisingly, the beach ridges date to MIS 7 (~190 ka) and imply relative sea level of about 4 m higher than present.

Webster et al present new sea level indicator points from the Great Barrier Reef in Australia from the Early Holocene. They find little support for the so-called "Meltwater Pulse 1B", a hypothesized >11 m sea level rise in 350 years.

> At our current rates of burning coal, fossil gas and petroleum, if we got 8 inches or so of sea level rise by 2050, the world’s largest 136 coastal cities would suffer $1 trillion per year of losses.

"A slow-moving crisis of sinking land and rising water is playing out along America's coastline.

In the past 100 years, sea levels have climbed about a foot or more in some U.S. cities – 11 inches in New York and Boston, 12 in Charleston, S.C., 16 in Atlantic City, 18 in Norfolk, Virginia, and 25 in Galveston, Texas, according to the National Oceanic and Atmospheric Administration..

Seas are forecast to rise from 8 inches to 23 inches along the nation’s coasts by 2050, with the higher increases along the northern Gulf Coast and mid-Atlantic. Every inch of additional water is expected to move farther inland making flood events worse and putting more properties at risk.

Meanwhile, in many coastal areas, the land is sinking, making flooding an even greater issue."

#ClimateChange #SeaLevel - Warming of +1.5 °C is too high for polar ice sheets - "Here we synthesise multiple lines of evidence to show that +1.5 °C is too high and that even current climate forcing (+1.2 °C), if sustained, is likely to generate several metres of sea-level rise over the coming centuries, causing extensive loss and damage to coastal populations and challenging the implementation of adaptation measures." - Stokes, C.R., Bamber, J.L., Dutton, A. et al. Warming of +1.5 °C is too high for polar ice sheets. Commun Earth Environ 6, 351 (2025). doi.org/10.1038/s43247-025-022
