  1. 6-12 inches? Won't that cover MDR?

    El Nino is growing, and becoming more dangerous than ever, because we've allowed the richest of the rich, the sociopaths' club, to rule us with their hateful, racist, corrupt, con artist insanity. All they give a rat's ass about is money. Not life. Not kids. Not the future. Not you. Not me. Not the country. Not the planet. They are selfish beyond belief. Their beliefs are born of stimulant abuse - the things they say are what my parents' generation called "drugs talking." Yet the people of this planet won't rise up, and worse than that, continue to use their abusive AI products.

    You're all doing this to us, arm-in-arm, like you're at a HS pep rally. Go team.

  5. California coast braces for another battering as new El Niño-related wave emerges in Pacific

    California beach communities are expected to see rising sea levels in the coming weeks as El Niño continues…

  6. Coastal Flooding At Predictable Hours

    “When do coastal floods happen? ⏱️🌊
    A new study [link above] shows that, in many tide-dominated coastal regions, flooding tends to occur at specific and recurring times of day. Rather than being completely random, flood events often cluster around predictable hours driven by local tidal patterns.
    By analysing coastal flood observations from the UK and the US, [the authors] show[ed] that the timing of flood events can be highly structured, with some locations experiencing floods disproportionately during certain parts of the day.
    This adds a temporal dimension to coastal flood risk. We often focus on how frequently floods occur, how severe they are, and where they happen. This study highlights that when they occur may also matter, particularly as rising sea levels increase the frequency of coastal flooding.
    The findings provide a useful perspective for coastal adaptation, risk communication, and emergency planning…”

    “Flooding is typically perceived as a sudden and unpredictable hazard. Here, [they] show that recurrent flooding can occur at highly predictable times in tidally dominated coastal systems. This predictability stems from phase-locking of tidal constituents and constituent pairs with the solar day, causing peak tides to recur at consistent local times set by regional tidal propagation. Using tide-gauge records from the United States and the United Kingdom, [they] quantif[ied] the intraday timing of coastal flood events and show strong clustering at specific hours, particularly where semidiurnal or mixed tides dominate. For example, floods in Boston cluster around noon and midnight, whereas in southern California they occur in the morning. Sites with stronger non-tidal variability show weaker clustering. This temporal predictability extends beyond nuisance flooding to larger consequential events involving inundation, road closures and infrastructural damage, highlighting opportunities for anticipatory risk communication, emergency planning and time-sensitive coastal adaptation…”

  7. Beyond The 100-Year Flood - Probabilistic Flood Hazard Assessment For King And Pierce Counties Under Future Climate Scenarios

    [part of my old stomping ground as an engineering geologist]
    H/T @Kees Nederhoff
    “Flood maps are usually built from a single design storm. For King and Pierce Counties in the Pacific Northwest (USA), [the authors] tried the opposite - simulate 82 years of actual coastal and river conditions (plus 18 synthetic years) with SFINCS and let the statistics fall out cell by cell. That took about 5,400 yearly simulations and 194,000 CPU hours on USGS's Hovenweep HPC. Worth it!
    The design-event shortcut turns out to hide a real hazard. A deterministic 10-year event underestimated flood depths by up to half a meter compared to the continuous runs.
    The bigger surprise [to the authors] was how one-sided the climate signal is. One metre of sea level rise takes King County's expected annual flooded area from 161 --> 787 hectares, almost a factor of five. Changes in storminess over the same horizon barely register. And somewhere between 100 and 150 cm of SLR, land that never floods today starts flooding fast. If you plan adaptation in Puget Sound, that threshold matters more than any single return-period map.
    [They] also propose Expected Annual Flooded Area (EAFA) as a probability-weighted alternative to the binary "inside or outside the 100-year zone" label…”

  10. The impacts of fossil fuel emissions are gnawing on Australia's coastline

    "Australia's exposure to current and future risks from the sea, including coastal erosion, king tides and rising sea levels, was "very high", The Insurance Council of Australia.

    "Sea level rise caused by climate change would mean the issue was not going away, and Australians needed to consider what we valued about our coastline."

    "Why a seawall might not protect both beaches and homes from coastal erosion...We'll end up with a giant wall around our beaches, or around our whole coastline. That's not saving the landscape, that's saving the infrastructure. We've got to slow down development and look at what we value about the beach."

    Professor Kennedy "said governments would need to consider buying back beachfront land and rehabilitating it, to protect both infrastructure and the beach."

  11. Ocean water is rushing miles underneath the ‘#DoomsdayGlacier’ with potentially dire impacts on #SeaLevelRise

    By Laura Paddison, CNN
    Published May 22, 2024

    "The #ThwaitesGlacier in #WestAntarctica — nicknamed the 'Doomsday Glacier' because its collapse could cause catastrophic sea level rise — is 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.

    "#Thwaites, which already contributes 4% to global #Sea Level rise, holds enough ice to raise sea levels by more than 2 feet. But because it also acts as a natural dam to the surrounding ice in West Antarctica, scientists have estimated its complete collapse could ultimately lead to around 10 feet of sea level rise — a catastrophe for the world’s #coastal communities."

  13. To start off the 1 paper per week challenge of this year, here is my #PaperOfTheWeek, or rather #PreprintOfTheWeek 😀

    tc.copernicus.org/preprints/tc

    They present and evaluate a new one-layer dynamical model to improve the fine-scale representation of #melt patterns under #Antarctic #IceShelves. Interesting to see how this can be applied to improve future #SeaLevel projections!
    Quite technical but interesting for #ocean and #IceSheet #modelers!
