Steven Zekowski> 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 href="https://freeradical.zone/tags/ClimateChange" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ClimateChange</a> <a href="https://freeradical.zone/tags/ClimateScience" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ClimateScience</a> <a href="https://freeradical.zone/tags/SeaLevel" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SeaLevel</a> <a href="https://freeradical.zone/tags/geography" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#geography</a>The 136 Largest Coastal Cities, including Egypt's Alexandria, face $1 Trillion Losses per Year from Sea Level Rise by 2050 <a href="https://www.juancole.com/2025/05/including-alexandria-trillion.html" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://www.juancole.com/2025/05/including-alexandria-trillion.html</a>

Rhinos Worry MeSea level rise will become unmanageable at just 1.5C of global heating and lead to “catastrophic inland migration”...the new analysis found that even if fossil fuel emissions were rapidly slashed to meet [1.5C], sea levels would be rising by 1cm a year by the end of the century, faster than the speed at which nations could build coastal defences.The researchers said the “safe limit” temperature for ice sheets was hard to estimate but was likely to be 1C or lower. Sea level rise of at least 1-2 metres was now inevitable, the scientists said.“Continued mass loss from ice sheets poses an existential threat to the world’s coastal populations.”<a href="https://www.theguardian.com/environment/2025/may/20/sea-level-rise-migration" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://www.theguardian.com/environment/2025/may/20/sea-level-rise-migration</a><a href="https://climatejustice.social/tags/Climate" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Climate</a> <a href="https://climatejustice.social/tags/ClimateCrisis" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ClimateCrisis</a> <a href="https://climatejustice.social/tags/ClimateCollapse" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ClimateCollapse</a> <a href="https://climatejustice.social/tags/SeaLevel" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SeaLevel</a>

Dr. Evan J. GowanPaleo sea level estimates from before 12,000 years ago are pretty rare. Medri et al make estimates of paleo sea level between 13.8 and 15.9 thousand years ago off the coast of central California, estimating paleo sea level between 86-99 m below present after tectonic correction.<a href="https://fediscience.org/tags/SeaLevel" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SeaLevel</a> <a href="https://fediscience.org/tags/California" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#California</a> <a href="https://fediscience.org/tags/Paleoclimate" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Paleoclimate</a> <a href="https://doi.org/10.1016/j.quascirev.2025.109408" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://doi.org/10.1016/j.quascirev.2025.109408</a>

Dr. Evan J. GowanMaxwell et al investigate fossil coral reefs on Luzon Island in the Philippines to determine past relative sea level and tectonic uplift rate. They conclude that it is 1.17 mm/yr, based on analysis of the MIS 5e terrace, currently at 155 m. <a href="https://fediscience.org/tags/SeaLevel" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SeaLevel</a> <a href="https://fediscience.org/tags/Philippines" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Philippines</a> <a href="https://fediscience.org/tags/Paleoclimate" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Paleoclimate</a> <a href="https://fediscience.org/tags/Tectonics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Tectonics</a><a href="https://doi.org/10.1016/j.geomorph.2025.109796" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://doi.org/10.1016/j.geomorph.2025.109796</a>

Dr. Evan J. GowanFatourou et al use biological proxies to investigate the connection of the Gulf of Corinth in Greece with the Mediterranean Sea during the Middle and Late Pleistocene. The connection for the past 400,000 years has been through the western Rion Sill, which is currently at 60 m depth. During glacial periods, sea level fell sufficiently to isolate the Gulf of Corinth from the Mediterranean Sea. Therefore, this record can be used as a way to estimate global ice volume. The major glacial periods of MIS 18, 14, 8, 6, 4 and 2 show a complete isolation of the Gulf.The major interglacials of MIS 17, 13, 11 and 9 indicate fully connected conditions. MIS 7 shows fluctuations, indicating that ice volume varied. This is perhaps not surprising, since there is a large interruption in MIS 7 with a sharp rise in δ¹⁸O in the marine records, likely a brief glaciation.During MIS 5, there is also fluctuations, with evidence of isolation during the MIS 5b stadial. During MIS 3, there is evidence that sea level must have risen enough that there was periodically a connection with the Mediterranean Sea (i.e. sea level > -60 m).Obviously, pin-pointing a specific sea level from these data is difficult, since the height of the sill likely varied due to tectonics, and the "connection" based on these proxies probably does not depend precisely on sea level being above or below -60 m.<a href="https://fediscience.org/tags/Paleoclimate" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Paleoclimate</a> <a href="https://fediscience.org/tags/SeaLevel" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SeaLevel</a> <a href="https://fediscience.org/tags/Greece" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Greece</a> <a href="https://fediscience.org/tags/Mediterranean" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Mediterranean</a> <a href="https://fediscience.org/tags/IceSheets" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#IceSheets</a><a href="https://doi.org/10.1016/j.quascirev.2025.109393" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://doi.org/10.1016/j.quascirev.2025.109393</a>

Dr. Evan J. GowanHijma et al provide a high resolution reconstruction of sea level change during the early Holocene from the North Sea. They find there were two periods of relatively high sea level rise, at around 10.3 and 8.3 ka.<a href="https://fediscience.org/tags/SeaLevel" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SeaLevel</a> <a href="https://fediscience.org/tags/Holocene" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Holocene</a> <a href="https://fediscience.org/tags/GlacialIsostaticAdjustment" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#GlacialIsostaticAdjustment</a> <a href="https://fediscience.org/tags/IceSheets" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#IceSheets</a> <a href="https://doi.org/10.1038/s41586-025-08769-7" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://doi.org/10.1038/s41586-025-08769-7</a>

Bob LeFridge :tinoflag:I live on a beach and this is quite big.Minimum floor levels are being raised in low-lying coastal parts of Dunedin, effective today.When my neighbour built about ten years ago, the minimum was 0.5m. The new minimum floor level is 3.05m - 3.17m above sea level "in certain areas".Three metres! While I approve the forward thinking, we'll have a lot of houses on poles.
