When #SeaLevelRise touches septic tanks, communities are in deep doo-doo.
"In 1999, with evidence that water quality was deteriorating along parts of the #Florida Keys, the state mandated that the island chain eliminate the use of tens of thousands of #SepticTanks and other outdated waste systems. The cost reached roughly $1 billion as Monroe County built centralized sewage and hooked up thousands of homes and businesses.
"#Mangroves are threatened by deforestation, development, pollution, and dam construction, but the risk to these ecosystems is increasing due to #SeaLevelRise and the increased frequency of severe storms associated with climate change. #ClimateChange threatens one third (33%) of the mangrove ecosystems assessed."
An international tribunal on Tuesday delivered a decision that green groups and leaders of small island nations celebrated as a “groundbreaking victory for ocean and climate protection."
"Big changes to #Antarctic sea ice will have a profound effect on other parts of the planet. In addition to protecting the exposed edges of Antarctica’s continental ice shelves from waves, the formation of sea ice acts as an engine for ocean currents and influences weather patterns in the Southern Hemisphere, the researchers said."
"A team of glaciologists led by researchers at the University of California, Irvine used high-resolution satellite radar data to find evidence of the intrusion of warm, high-pressure seawater many kilometers beneath the grounded ice of West Antarctica's #Thwaites Glacier."
NEW STUDY: "#Ocean water is pushing miles beneath #Antarctica’s “#DoomsdayGlacier,” making it more vulnerable to melting than previously thought, according to new research which used radar data from space to perform an X-ray of the crucial glacier."
"...scientists have estimated 👉its complete collapse could ultimately lead to around 10 feet [3 meters]of sea level rise👈 — a...
...catastrophe for the world’s coastal communities."
"....we have solid observations of what is going on.”
"In a separate study, also published Monday, researchers from the #BritishAntarcticSurvey looked at the reasons for the record low levels of sea ice surrounding Antarctica last year...used #ClimateModels to predict the potential speed of recovery from such extreme sea ice loss and found that 👉even after two decades,...
...the world’s widest glacier and roughly the size of Florida.
It’s also Antarctica’s most vulnerable and unstable glacier, in large part because the land on which it sits slopes downward, allowing ocean waters to eat away at its ice."
"He said the faster rate of rising sea-level on #Bangladesh's coast will increase the vulnerability of coastal people and their livelihoods.
Salinity, coastal inundation, and storm surge height will increase. It could impact agriculture, food security, disaster management, health, drinking water supply, and coastal infrastructure.
The world's largest #mangrove forest and its ecosystem will be affected by rising sea-level and salinity."
"Many of the scientists envisage a “semi-dystopian” future, with famines, conflicts and mass migration, driven by heatwaves, wildfires, floods and storms of an intensity and frequency far beyond those that have already struck."
People here read things like "mass migration" and only picture people from Africa, the Middle East and further afield, coming to Europe.
What people here aren't yet considering is how soon they themselves could be forced to collect as much as they can carry, and leave their homes to find higher ground.
"Generally, the city envisions a response that resembles a long jigsaw puzzle: small and varied projects that lock together to form one continuous flood barrier. All together, the projects would cost several billion dollars."
"Satellites equipped with radar or specialised sensors can measure the height and structure of forests... Satellite images can also help engage local people in restoration efforts and... help scientists map changes along the coast and assess how vulnerable mangroves might be."

"The conditions beneath ice sheets play an important role in governing ice sheet behavior and determining their vulnerability to climate change..." https://www.youtube.com/watch?v=ufUBYl65nEg#Glaciers#Cryosphere#SeaLevelRise
"There is now a real danger that some significant #SeaLevelRise will occur in the next few decades as the ice sheets and glaciers of west #Antarctica continue to shrink. These are being eroded at their bases by warming ocean water and could disintegrate in a few decades."
Rapid melting of ice sheets and glaciers drives a unique geometry, or fingerprint, of sea level change. As an ice sheet loses mass, its gravitational attraction on the nearby ocean is reduced, causing ocean water to migrate away from the ice sheet. https://www.youtube.com/watch?v=lD_t-7YQnO8#SeaLevelRise#Glaciers#Cryosphere
