Interactive map shows #Florida parcels that will be flooded (blue shading) using sea level as of 2016 plus a two foot rise in sea level. Click any parcel for attribute data. H/T @ai6yr for the map idea.
Map covers all of Florida. It is centered on Miami Beach when it opens.
Glaciers exposed to the #ocean are melting much faster than previously predicted. 🧊 ☀️
Melt #water underneath the #glacier in the 'grounding zone cavity' significantly increases the projections of glacier mass loss as these zones reduce the amount of resistance glaciers experience as they flow out into the sea.
The result is that past models underestimate the severity of #sealevel rise over the coming decades

Le pitch : « Quand les terres ont été submergées par les océans, d'autres problèmes n'ont pas tardé à arriver. Avec les ressources de plus en plus difficiles à obtenir, les humains sont devenus leurs propres ennemis se battant pour le moindre lopin de terre émergé. »
NASA Climate Change: Towards a New Generation of Glacial Isostatic Adjustment Models: Climate Seminar
"Broadly speaking, glacial isostatic adjustment is the study of how the solid Earth and gravity field respond to changes in regional- to global-scale ice mass redistribution...." https://www.youtube.com/watch?v=LmVYlMe-k_g#Glaciers#IceAge#SeaLevel#Cryosphere
Modelling paleo sea level in western France has been notoriously difficult, so much so that researchers thought it would be impossible without using complicated 3D Earth models. Although preliminary, PaleoMIST 1.0 (my paleo ice sheet/topography reconstruction) does a pretty good job using a simple spherically symmetric Earth model. #PaleoSeaLevel#IceSheets#SeaLevel#ClimateChange#France
Marra et al date two shoreline deposits in the west side of Italy, which correspond to the MIS 5e interglacial and MIS 5c interstadial. They found that the MIS 5c sea level was similar to present day. Even accounting for tectonic uplift, which seems relatively small considering the elevation of the MIS 5e deposit at 9.5 m, this site implies much higher sea level than infered from marine δ¹⁸O records. #paleoclimate#SeaLevel#PaleoSeaLevel#LastInterglacialhttps://agupubs.onlinelibrary.wiley.com/doi/10.1029/2023PA004679
Richards et al determine an estimate of global mean sea level for the Mid-Pliocene (~3 million years ago) using a dynamic topography model constrained using sea level indicators in Australia. They estimate that sea level was about 16 m higher than present, which would correspond to Greenland and West Antarctica completely retreating, with a possibility of part of East Antarctica retreating as well. #PaleoClimate#SeaLevel#IceSheets#ClimateChangehttps://www.science.org/doi/full/10.1126/sciadv.adg3035
80 percent of the #Maldives is less than a metre (three feet) above #SeaLevel.
And while fortress-like walls ringing tightly-packed settlements can keep the waves at bay, the fate of the beach islands the tourists come for are uncertain.
FOR OVER three decades the Pacific island country of Tuvalu has implored industrialised countries to cut their greenhouse-gas emissions. For over three decades global temperatures have ticked up. Tuvalu’s government warns that its territory could slip underwater by the end of the century. “It’s a matter of disappearing...
I’ve been doing some investigations into sea level data for work and I wanted to share this sub ice elevation map of Australia and surrounds because it looks pretty. 🗺️
"We conclude with a high degree of confidence that #GulfStream transport has indeed slowed by about 4% in the past 40 years.
The Gulf Stream affects regional #weather, #climate, and coastal conditions, including European surface air temperature and #precipitation, coastal #SeaLevel along the Southeastern U.S., and North Atlantic #hurricane activity. "
I'm nearer to the Great Lakes than I am to any ocean, so this is all mostly abstract for me, although this Sea Level Rise slider from NOAA makes things concrete (for the case of the U.S. anyway...) https://coast.noaa.gov/slr/
