No challenge to this nonsense from the BBC as usual. Sea level appears to be rising at a small 3mm per year. Atolls in the Pacific nations of the Marshall Islands and Kiribati, as well as the Maldives archipelago in the Indian Ocean, have risen up to 8 percent in size (Ford and Kench, 2020). 89% of the globe’s islands and 100% of large islands have stable or growing coasts (Duvat, 2019). No island larger than 10ha decreased in size. As regards NOAA tide gauge data, let's look at some examples from around the world. N.B. All sites show a linear Relative Sea Level Trend: Kanmen, China 2.40mm/yr; Sydney, Australia 0.75mm/yr; Ferandina Beach, Florida 2.20mm/yr; Los Angeles, California 1.04mm/yr; Mera, Japan 3.8mm; Cascais, Portugal 1.32mm/yr; Newlyn, UK 1.94mm/yr. Jevrejeva, et al (2014) estimated 2 mm/year (± 0.3), and Church and White (2006) estimated 1.7mm/year (± 0.3). So that's a total rise of between 126 and 151mm (less than 6 inches) from 2024 to the end of the century. A paper from Frederikse et al (2018) shows a global trend of 1.5 ± 0.2 mm yr−1 over 1958-2014. That's 6cm by 2050, and 30cm by 2100. Or try PSMSL data: Kwajalein (Marshall Islands) 1.95mm/yr; Maldives (Indian Ocean) 3.21mm/yr; Lautoka (Fiji Islands, Pacific Ocean) 3.50mm/yr; Port Elisabeth (South Africa) 2.34mm/yr. Anyway, if you prefer satellite data NOAA's trend was +3.0mm/year Global Mean Sea Level (1993-2022), again linear last time I looked for each set of satellite data (but hey, it may have accelerated in the last month). NASA satellite data (1993-present) for Global Mean Sea Level shows a rise of 3.3mm per year. That's the same as two stacked penny coins. There is no relationship to the increase in CO2 in the atmosphere. It's going to be decades before even your big toe is submerged.
