My son was there today. He is with his grandma's, they live not far from there. Maybe a mile or two. They didn't think much of it.

We are looking at a 3rd consecutive La Nina this summer.
https://www.theguardian.com/australia-news/2022/aug/17/eastern-australia-faces-wet-weather-and-flooding-with-70-chance-of-third-consecutive-la-nina

The closest city to me Maryborough flooded 3 times last summer, so did Gympie. Brisbane flooded again, that's twice in 10 years.

Lismore flooded twice last summer and broke the flood record by an additional 2 meters.

When we had rainfall like this in 2011 the vegetation grew like crazy, followed by almost a decade of sporadic El Nino events, everything dried out and then the bushfires started.
Tasmanian forests that had never seen a severe bushfire were devastated. Over half of Fraser Island near where I live was burnt out. New South Wales and Queensland saw massive bushfires, as did south Western Australia and parts of Victoria and the A.C.T.

My household insurance went up 27% this year due to the ongoing floods. A lot of localities are now too costly to insure. It ruins the roads and ruins the crops so fruit & vegetable prices go up.
The weather extremes are a reality and the costs are adding up.

Abstract
The stability of widespread methane hydrates in shallow subsurface sediments of the marine continental margins is sensitive to temperature increases experienced by upper intermediate waters. Destabilization of methane hydrates and ensuing release of methane would produce climatic feedbacks amplifying and accelerating global warming. Hence, improved assessment of ongoing intermediate water warming is crucially important, especially that resulting from a weakening of Atlantic meridional overturning circulation (AMOC). Our study provides an independent paleoclimatic perspective by reconstructing the thermal structure and imprint of methane oxidation throughout a water column of 1,300 m. We studied a sediment sequence from the eastern equatorial Atlantic (Gulf of Guinea), a region containing abundant shallow subsurface methane hydrates. We focused on the early part of the penultimate interglacial and present a hitherto undocumented and remarkably large intermediate water warming of 6.8 °C in response to a brief episode of meltwater-induced, modest AMOC weakening centered at 126,000 to 125,000 y ago. The warming of intermediate waters to 14 °C significantly exceeds the stability field of methane hydrates. In conjunction with this warming, our study reveals an anomalously low δ13C spike throughout the entire water column, recorded as primary signatures in single and pooled shells of multitaxa foraminifers. This extremely negative δ13C excursion was almost certainly the result of massive destabilization of methane hydrates. This study documents and connects a sequence of climatic events and climatic feedback processes associated with and triggered by the penultimate climate warming that can serve as a paleoanalog for modern ongoing warming.
Because ocean intermediate waters impinge on marine sediments that often contain potentially unstable shallow subsurface methane hydrates (1–3), better understanding is crucial about the factors that contribute to intermediate water warming and their potential extent, especially in context with ongoing global warming. Simulation studies have suggested warming of intermediate waters has been limited to ∼1.5 °C to 3 °C, and that such warmings were insufficient to significantly affect the stability of shallow subsurface methane hydrates (2–5). However, the magnitude of intermediate water warming can be significantly amplified by meltwater-induced weakening of atmospheric and ocean circulation (6–11), an amplification not considered in the simulations that examined potential gas hydrate destabilization (2–5). A recent simulation study estimates the contribution of weak Atlantic meridional overturning circulation (AMOC) at 0.3 °C to 0.4 °C to the warming of the intermediate waters for a business-as-usual scenario at the end of the 21st century (12), a modest contribution compared to observations in past climate studies (6–11). An accelerated mass loss of the Greenland ice sheet and the associated freshening of subpolar North Atlantic sea surface waters represents a robust proxy of ongoing rapid global warming (13). Causally linked to this freshening is increasing evidence of a steady weakening of the AMOC (14, 15). Warming of the intermediate waters by 3 °C to 5 °C in response to a meltwater-induced AMOC weakening is a robust feature of the last deglacial (6–11). This corresponds to pockmark formations on the ocean floor and extremely negative foraminiferal δ13C values in sediment sequences that reflect methane hydrate dissociation in response to intermediate water warming related to meltwater-induced weakening of AMOC and associated changes in atmospheric circulation during the last deglacial (10, 11, 16–18). A sequence of episodic, extremely low foraminiferal δ13C values observed in Late Quaternary sediments of Santa Barbara Basin led to the formulation of the “clathrate gun hypothesis” (10, 11). The hypothesis states that episodic warming of intermediate waters during the last glacial and early deglacial led to dissociation of shallow subsurface methane hydrates and release of methane, contributing to the observed increases of atmosphere methane concentrations, further contributing to climatic warming episodes (10, 11). The key findings of our study add to a growing body of observational findings strongly supporting the “clathrate gun hypothesis” (10, 11). The magnitude of intermediate water warming in response to AMOC weakening most likely is critically dependent on the existing mean climatic state. Importantly, the interval we have studied is marked by a mean climate state comparable tofuture projections of transient global climate warming of 1.3 °C to 3.0 °C (19). Our findings thus provide insights about major meltwater-induced intermediate water warming during warm episodes like the present with the potential to destabilize structural-type methane hydrates.
In this study, we focus on the early part of the Eemian interglacial episode (128,000 to 125,000 y before present [ky BP]), the youngest episode when tropical oceans were warmer than the Holocene by up to 2 °C (20–22). We show that the combination of a warm mean climate state and a relatively brief and modest episode of meltwater-induced AMOC weakening produced an exceptionally large intermediate water warming that significantly exceeds the stability field of methane hydrates. Coincident with this warming, we demonstrate that the dissolved inorganic carbon across the entire 1,300-m water column was marked by an anomalously low carbon isotope ratio (13C/12C) which we interpret to indicate destabilization of shallow subsurface methane hydrates and ensuing methane oxidation.

That was too dense for me to read; started partying at midnight. But when I clicked on the link it said "penultimate glacial warming". Penultimate means right before the end, right?

It means second to last but in this context I think it's more of a chronological reference than a prophecy, as in "the glacial warming period most recently preceeding the current one"

OK. When was the last one? Was it one of those naturally occurring ones the right keeps bringing up, so we have nothing to worry about.

I just remember "penultimate" from my 5 year grad school poker game when the couple who hosted it said this is the penultimate hand. The professor that I worked for as a T.A. and her boyfriend, another demographer, used to be regulars in the game, but they quit coming right before I started because it was a very smoky room.

125,000-ish years ago and yeah, it was natural.  The key takeaway is that melting glaciers can slow a key Atlantic current that can lead to warmer waters at depths where methane hydrates accumulate which in turn can lead to massive fossil methane releases more or less all at once.

I thought this was one of the fairly well known feedback mechanisms? Or am I thinking of methane frozen into the ice at the poles?

Rewetting dried wetlands could stop 100 billion tons of CO2 emissions






There is a huge project going on right now.on the South end of Eureka that is attempting to reclaim former wetlands turned into ag land (and I think a former nuclear facility or power plant nearby.)

However,  the real reason they are doing this (because it was still grazing pasture with hundreds of cattle a few.months ago) is the create channels to send/divert floodwaters from the bays away from the highway and residential areas and fishing docks nearby.


Eureka, and even more so Arcata, will both be underwater within the next twenty years. And that is.an extremely generous guess. Some of the groups who did the projections say it could be underwater in five years or less,  with a few inches of sea level rise.

There has to be rich people buying up future shore property, especially where the elevation will keep it above water for a while.

Yea there were signs up around campus saying "do not use this elevator from 4-9pm" ...I don't think they actually shut the power off here though.
