Our new paper is out: We're exploring the intersection of electrochemical OAE and concrete waste recycling - turns out they're a match made in heaven. One produces weak waste acid and the other requires weak acid to valorize demolition waste!

Negative Emission Enabled by Combining Ocean Alkalinity Enhancement and Waste Concrete Upcycling

Electrochemical ocean alkalinity enhancement (OAE) is a promising technology for negative carbon emissions, but the resulting dilute acid stream poses a disposal challenge. This study presents an inno...

I'm not sure many folks realize just how persistent the warming from CO2 is.

Here is a set of 1000-year climate model runs (using FaIR) simulating one year of CO2 emissions (40 gigatons in 2020); a millennia later the world has not cooled back down!

Whoa. GORGEOUS new image from JWST 🔭 dropped today: "what appears to be a craggy, starlit mountaintop kissed by wispy clouds is actually a cosmic dust-scape being sculpted by the scorching radiation and punishing winds of massive newborn stars" (!) More info at: webbtelescope.org/contents/new...

A golden-rusty "mountain" rises infront of a field of sparkling white stars set in shades of blue, with wisps of smoky cirrus-like clouds near the peak of the "mountain."

This dramatic scene captured by NASA’s James Webb Space Telescope looks like a fantastical tableau from J. R. R. Tolkien’s The Lord of the Rings. But truth is even stranger than fiction. In reality, what appears to be a craggy, starlit mountaintop kissed by wispy clouds is actually a cosmic dust-scape being sculpted by the scorching radiation and punishing winds of massive newborn stars.

Called Pismis 24, this young star cluster is home to a vibrant stellar nursery. Super-hot, infant stars – some almost 8 times the temperature of the Sun – are carving a cavity into the wall of the star-forming nebula. Dramatic spires jut from the glowing wall of gas, resisting the relentless radiation and winds. They are like fingers pointing toward the hot, young stars that have sculpted them. The fierce forces shaping and compressing these spires cause new stars to form within them.

One of the closest sites of massive star birth, Pismis 24 resides in the core of the nearby Lobster Nebula, approximately 5,500 light-years from Earth in the constellation Scorpius.

New paper estimates the capacity of underground CO2 storage to be just 1290–2710Gt of CO2 www.nature.com/articles/s41...
That's not as much as it sounds - only 30-60 yrs of current emissions, that's all - we couldn't even pay back our CO2 debt this way, never mind keep burning fossil fuels with CCS

Clearly we need more data to constrain global circulation models if we want to reduce the uncertainty in OAE predictions. We hope that this work will inspire, direct and inform future data gathering and experiments.

Mike Tyka @mtyka.bsky.social · Sep 4

Finally we tried to simply turning off all the sophisticated biology modeling in ECCO-Darwin (i.e. the Darwin part). It turned out that this made virtually no difference to the OAE uptake trajectory - OAE-driven CO2 uptake appears to be primarily a function of bulk transport and gas exchange.

Mike Tyka @mtyka.bsky.social · Sep 4

We also looked at the difference attributable to the divergent prediction of the horizontal plume trajectory (even if the gas exchange parametrization had been equal) and find that plume trajectory is significant. This is especially true of plumes end up going under ice or towards a high-wind zone.

Mike Tyka @mtyka.bsky.social · Sep 4

We tried to figure out what other aspects of each model are responsible for the observed differences (other than subduction). The first suspect is the parameterization of wind speed and carbonate chemistry. The difference in wind params (and therefore gas exchange velocity) was the major influence.

Mike Tyka @mtyka.bsky.social · Sep 4

It's interesting too that the models disagreed more for coastal injection sites but agreed better for sites further off-shore. This might have to do with the complexity of the near-shore water movements.

Mike Tyka @mtyka.bsky.social · Sep 4

The inter-model variation is greater than the inter-annual variation within a model.

Mike Tyka @mtyka.bsky.social · Sep 4

Unsurprisingly there is a strong correlation with the rate of subduction experienced by the alkalinity plume. We find this is the primary driver of the differences. If the model predicts faster subduction, the OAE efficiency suffers more.

Mike Tyka @mtyka.bsky.social · Sep 4

Later into the simulation however there is some degree of convergence, which we expect to continue past the timeframe we simulated, since it should eventually converge to the predicted maximum set by the carbonate chemistry.

Mike Tyka @mtyka.bsky.social · Sep 4

It turns out that the predicted uptake efficiency following an OAE deployment varies quite a bit in year 1-10 depending what model you ask. Here we compare CESM2/MARBL (1x1 deg, the one used for the atlas (www.nature.com/articles/s41...) with ECCO-Darwin LLC270 (0.3x0.3deg).

Mike Tyka @mtyka.bsky.social · Sep 4

Our new paper with Mengyang Zhou, Elizabeth Yankovsky, and Dustin Carroll is out as a preprint: egusphere.copernicus.org/preprints/20... "Substantial inter-model variation in OAE efficiency between the CESM2/MARBL and ECCO-Darwin ocean biogeochemistry models"

This would more or less halt the ability of scientists and academics from visiting the US to give talks, attend meetings and workshops, collaborate with peers on research and I think that is the primary point. 🧪

The largest photomosaic of the Andromeda galaxy, assembled from Hubble observations, took more than 10 years of data collecting and was created from more than 600 snapshots!

➡️ And it's available for download in really large sizes: go.nasa.gov/44Uvyhc 🔭 🧪

The Andromeda galaxy, a spiral galaxy, spreads across the width. It is tilted nearly edge-on to our line of sight so that it appears as an extreme oval on its side. The borders of the galaxy are jagged because the image is a mosaic of smaller, square images. The outer edges of the galaxy are blue, while the inner two-thirds are yellowish with a bright, central core. Dark, dusty filamentary clouds wrap around the outer half of the galaxy’s disk. At 10 o’clock, a smaller dwarf elliptical galaxy forms a fuzzy, yellow blob. Hubble’s sharp vision distinguishes about 200 million stars within the image. The background of space is black. There are what appears to be steps toward the bottom, mainly toward the middle, which indicates where no data were taken.
