Question for anyone who's lived on the of for many years: The other day I visited Carlsmith Beach Park -- a favorite spot, but this was my first time there right at high tide -- and was surprised to see the paved path that leads to steps going down into the water completely submerged. Is this the way it's always been, or is it a more recent development due to rise? Mahalo for any info!

Study finds ‘direct evidence’ of amplification on continent as scientists warn of implications of loss. is likely @ almost 2x rate of rest of world & faster than models are predicting w far-reaching implications for rise. analysed 78 Antarctic to recreate temperatures going back 1,000 yrs & found the warming across continent was outside what could be expected from natural swings. theguardian.com/world/2023/sep

Weil-Accardo provide a new set of paleo sea level constraints from the Last Interglacial from Madgascar, collected using modern field techniques and measurements. They find that relative sea level in this location was relatively stable at about 3.4 m above present between 129 and 115 thousand years ago. There is no evidence of fluctuations or higher relative sea level at this location. sciencedirect.com/science/arti

Yesterday's high tide is becoming today's new normal.

"Due to rise, coastal elevations that we once knew as marking the highest water level over a typical daily tidal cycle now correspond more closely to the average level of the sea"

One thing I have always considered doing is a climate science related podcast. I never went ahead with it, because it takes a lot of time to set something like that up. However, with my current bout of unemployment, this has crept back into my mind. The question is, is their an audience for a podcast that will undoubtedly be a very nerdy look at climate science?

The Nuuk area in western Greenland (the type locality of ) is one of the places where sea level is falling! Not only is ice melting, uncovering new rocks and unloading the lithosphere, but the mass of ice that's missing no longer attracts the water, so it recedes. Read more at the Arctic Hub:

Rush et al propose, based on a high resolution sea level record from Scotland, that the 8.2 ka event was caused not by the catastrophic drainage of proglacial lake Agassiz-Ojibway, but rather from the collapse and disintegration of the ice saddle that covered Hudson Bay. The 8.2 ka event was a brief period of cooler temperatures during the relatively warm mid-Holocene period. sciencedirect.com/science/arti

Zaretskaya et al present some preliminary results of dating last interglacial (MIS 5e, 130-115 ka) marine deposits from Zimnii Coast of the White Sea in northwestern Russia. They conclude these deposits represent a transgressive event, and some of the enviornmental indicators suggest that the peak sea level coincided with cold, Arctic climatic conditions. The ages they get are kind of young for MIS 5e, though. link.springer.com/article/10.1

Robertson et al evaluate the long term uplift rates in Crete by wave cut paleoshorelines, some of which are dated using ³⁵Cl dating. One of the interesting things is that they find that one of the shorelines dates to early MIS 3, and if correct suggests higher sea level than the global proxy based sea level reconstructions. However, this area is affected by glacial isostatic adjustment, which was not taken into account. I calculate it is on the order of 10 m. sciencedirect.com/science/arti

A question for the more scientifically inclined: I was just reading a story in the Post about sea level rise in New Orleans. They said that in some places it was as much as 7 inches. Now I know that isn't world wide. My question for you is; how can sea level rise be more in one place than another if the sea is a contiguous body of water?

En términos relativos a nuestra civilización, 2300 está ahí a la vuelta de la esquina y la empieza a dar señales de derretimiento.

La proyecciones indican que su contribución al para 2300 será de 1 m ya inevitable añadiendo lo que podamos o no evitar mediante mitigación de hasta 2,5 m para +2ºC y hasta 10 m en escenarios más pesimistas como RCP 8.5.

Simple projection of coasts in northern Europe with 65m sea level rise. 65m sea level rise is what we get by melted polar caps alone. The thermal expansion of oceans will add on top.
Other effects like rising or sinking of land are not taken into account here.

collapse: effects of if ocean current stops – and when it might happen

The collapse of the Gulf Stream is a major ‘tipping point’ in the climate crisis – and scientists say it must not happen

By Alex Nelson

"In February [2021], Stefan Rahmstorf told The Guardian that further weakening of the circulation could lead to more events in , including damaging across the UK.

"A scientist at the Potsdam Institute for Impact Research scientist said, Rahmstorf said: 'In 20 to 30 years it is likely to weaken further, and that will inevitably influence our weather, so we would see an increase in storms and in , and rises on the east coast of the .'"
