DoomsdaysCW<p>Physics-based indicator predicts tipping point for collapse of Atlantic current system in next 50 years</p><p>by Krystal Kasal</p><p>"The Atlantic Meridional Overturning Circulation (<a href="https://kolektiva.social/tags/AMOC" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>AMOC</span></a>) is an enormous loop of ocean current in the Atlantic Ocean that carries warmer waters north and colder waters south, helping to regulate the climate in many regions. The collapse of this critical circulation system has the potential to cause drastic global and regional climate impacts, like <a href="https://kolektiva.social/tags/droughts" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>droughts</span></a> and <a href="https://kolektiva.social/tags/ColderWinters" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ColderWinters</span></a>, especially in Northwestern Europe.</p><p>"Previous research has already indicated a weakening in the AMOC, but there has been uncertainty about when the AMOC will collapse under future climate change or whether it will collapse at all. But new research, now published in the Journal of Geophysical Research: Oceans, indicates that collapse of the AMOC is likely and that it might begin sooner rather than later.</p><p>"Using a new physics-based indicator and the Community Earth System Model (<a href="https://kolektiva.social/tags/CESM" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>CESM</span></a>), the study authors have produced new simulations of the AMOC collapse under various conditions.</p><p>"The researchers believe the new indicator better represents the water circulation compared to previously used parameters, such as the ocean's surface temperature. Instead, it represents a tipping point indicated by a sign change in surface buoyancy flux (Bflux) over a key part of the North Atlantic Ocean from 40°N to 65°N. They also compared their results to historical observations and data.</p><p>"Their simulations tested out 25 different climate models. They say that the AMOC was fairly stable until about 2020, but since then, there have been signs of weakening. Future modeling shows that, in high-emission scenarios, the AMOC collapse tipping point began as early as 2023 and as late as 2076, with a median tipping point at 2055. Under more intermediate scenarios, the tipping point was placed between 2026 and 2095, with a median of 2063.</p><p>"The study authors note, 'If the AMOC starts to collapse, it takes more than 100 years to reach a substantially weaker state. During that transition, the Northwestern European climate would change drastically and is expected to see colder winters, less rainfall, and more severe winter storms.'</p><p>"The study authors also note that many prior simulations only ran until around 2100, but letting simulations go further into the future might provide more accurate results. They say, 'Given these risks of AMOC tipping under climate change, we encourage modeling groups to simulate to at least the year 2200.'</p><p>"There were some limitations in this research; for example, most models did not include enhanced <a href="https://kolektiva.social/tags/GreenlandIceMelt" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>GreenlandIceMelt</span></a>, which could actually accelerate AMOC weakening. In some cases, background circulation can balance surface buoyancy gain. In these cases, the proposed indicator can also give false positives, but this is rare.</p><p>"There is still time for societies to limit the impact of eventual AMOC collapse or to develop adaptation strategies, but the study authors offer a stark warning, saying, 'To limit the risk of AMOC weakening and a potential collapse in the foreseeable future, global society needs to be on track of a <a href="https://kolektiva.social/tags/LowEmission" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>LowEmission</span></a> scenario and urgent <a href="https://kolektiva.social/tags/ClimateAction" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ClimateAction</span></a> is needed to guarantee this.'

What's the scale, what's the temporary tech fix, if any?<br>I have no idea. </p><p>Now I saw someone doing this simple equation:<br>50cm (global) <a href="https://fedifreu.de/tags/sealevelrise" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>sealevelrise</span></a> on a beach with 30° angle means 86cm less beach. <br>A beach with a 15° angle loses 186.6cm.<br>Don't know whether this is correct. <br>But our beach where I live is very shallow before it gets into higher, steeper dune landscape. I guess, 50cm from an AMOC collapse basically vanishes the beach within 150years. </p><p>That is, if the global 50cm rise were be the same at our beach! ... can't imagine how this would play out for real...</p>

Two key questions are how relevant is this exacerbation and whether tsunami design parameters are significantly affected. We perform a non-stationary probabilistic tsunami hazard assessment (nPTHA) in the Southern California bays of San Pedro and San Diego, with consideration of tsunamis generated by earthquakes in the Alaska-Aleutians (<a href="https://kolektiva.social/tags/ASZ" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ASZ</span></a>) and Cascadia subduction zones (<a href="https://kolektiva.social/tags/CSZ" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>CSZ</span></a>). We evaluate the changes of the maximum considered tsunami (<a href="https://kolektiva.social/tags/MCT" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>MCT</span></a>) design parameter, defined as a tsunami intensity that is exceeded with a 2% probability in 50 years. MCT elevation maps in the bays are calculated incorporating tides and SLR by means of a surrogate model. MCT elevations at assessed sites in San Pedro Bay and San Diego yield 2 m. The nPTHA shows that tsunamis generated in the ASZ zone are more hazardous in Southern California than those from the CSZ when evaluating MCT intensities. A comparison of scenarios with and without SLR also shows an increase of the MCT elevations of more than a foot in San Pedro Bay and San Diego, demonstrating that SLR causes a relevant impact, comparable to the influence of tides. The effect of SLR increasing MCT values is also comparable to the sensitivity of nPTHA results to some common earthquake epistemic uncertainties, such as the slip marginal distribution. Future tsunami hazard maps shall incorporate SLR when exposure times are long, as well as the uncertainty of tsunamigenic earthquake properties."<br> <br>Key Points</p><p> - Earthquakes in Alaska and Cascadia subduction zones produce tsunami hazards in Southern California that are exacerbated by sea level rise</p><p> - The elevation of maximum considered tsunamis (MCT) in San Pedro Bay and San Diego grow by more than a foot when SLR influence is included</p><p> - The impact of Alaskan earthquake epistemic uncertainties on MCT elevations in Southern California is similar to that of the sea level rise</p><p>Plain Language Summary</p><p>"Climate-change-driven sea level rise is expected to worsen tsunami hazards in the long term. Tsunami waves will be able to propagate over rising sea levels that will enable them to inundate higher land. In this study, we quantify the increase of tsunami hazards in Southern California due to sea level rise. We consider tsunamis originated in the Alaska and Cascadia subduction zones. Changes of tsunami design parameters, as a result of the sea level rise, are also analyzed. Namely, we analyze the changes of the 'maximum considered tsunami' (MCT) elevation, defined as the elevation exceeded with probability 2% in 50 years. We find that earthquakes of the Alaska Subduction Zone constitute the main <a href="https://kolektiva.social/tags/tsunamigenic" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>tsunamigenic</span></a> contributor. We also find that sea level rise increases MCT tsunami elevations by 0.3 m. With this increase, MCT levels reach 2 m in San Pedro Bay and San Diego. We compare the impact of sea level rise exacerbating tsunami hazards with the impact of common uncertainty sources of tsunami hazard assessment models. The uncertainty of earthquake models, for example, can produce differences in MCT levels that are comparable to the SLR influence."</p><p>Source:<br><a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2024EF005435" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">agupubs.onlinelibrary.wiley.co</span><span class="invisible">m/doi/full/10.1029/2024EF005435</span></a></p><p><a href="https://kolektiva.social/tags/ClimateCrisis" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ClimateCrisis</span></a> <a href="https://kolektiva.social/tags/ClimateCatastrophe" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ClimateCatastrophe</span></a> <a href="https://kolektiva.social/tags/TsunamiRisks" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>TsunamiRisks</span></a> <a href="https://kolektiva.social/tags/SeaLevelRise" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>SeaLevelRise</span></a></p>
