🚨New Paper!

Led by Joey Bisits, with @janzika.bsky.social, we explore the drivers of cabelling instability in the ocean using a first-of-its-kind turbulence-resolving simulation. See here for energy budgets, diffusion calcs and pretty pictures using Oceananigans: doi.org/10.1017/jfm....

“As the current slows down, it could impact the ocean’s ability to really absorb that extra heat and keep us protected, or keep us insulated from the impacts of global climate change.”

Strongest ocean current set to slow as ice sheets melt - ABC listen

The world's strongest ocean current could be about to slow down, as melting ice sheets see an influx of fresh water dumped into the Southern Ocean.

New research out today with colleagues Bishakhdatta Gayen and Andreas Klocker projects that the world’s strongest current, the Antarctic Circumpolar Current, may slow by 20% by 2050 in a high emissions future. So happy to have this out for the world to read!

Antarctic melt may slow the world's largest ocean current - "far-reaching impacts on global climate patterns, oceanic heat distribution, and marine ecosystems”.

Great piece by @taimoorsohail.bsky.social et al in The Conversation about the findings of their latest paper that just got out at Environmental Research Letters (doi.org/10.1088/1748...) regarding the biggest ocean current of all. 🌊

Melting Antarctic ice will slow the world’s strongest ocean current – and the global consequences are profound

Part of the system that pumps water, heat and nutrients around the globe is at risk. Climate change could slow the Antarctic Circumpolar Current down 20% by 2050.

After many years of long discussions, our paper on the new inverse method we call the Optimal Transformation Method (OTM) is finally out!

With OTM, we can infer global ocean heat/freshwater transports, correct air-sea flux products, and more!

Hello Bluesky! My new paper with Ryan Holmes is out now in JPO: using a new method to analyse time-varying processes' contributions to ocean heat transport. We found some interesting results associated with vertical mixing variability. Read it here: journals.ametsoc.org/view/journal...

This work suggests that the relative role of aerosols in cooling our climate is weakening since the 1980s, and may enable accelerated, unchecked heating due to GHGs. Check out the full text if interested!

3) We trace the drop in aerosols-driven ocean heat uptake efficiency to air-sea heat fluxes, which show reduced cooling in the tropics and sub-tropics since the 1980s.

Taimoor Sohail @taimoorsohail.bsky.social · Dec 4

2) The drop in aerosol- driven heat uptake efficiency has been centred around the tropical and sub-tropical ocean, while the high latitudes (i.e., Southern Ocean and North Atlantic) have continued to cool with the same efficiency as pre-1980s

Taimoor Sohail @taimoorsohail.bsky.social · Dec 4

1) The ocean heat uptake efficiency (how much cooling occurs in the ocean, per degree of surface cooling) due to human-released aerosols has dropped by 43% since 1980. Meanwhile, the ocean heat uptake efficiency of human-released greenhouse gasses has continued to climb.

In this work, we diagnosed the change in aerosol-driven ocean heat uptake efficiency in decadal time windows and depth and temperature layers. The main findings are:

Really proud of this work, which went from an idea back in August 2022, to a published piece this week! With co-authors Damien Irving, @janzika.bsky.social, and Jonathan Gregory, we explored the reduced impact of aerosols on our climate system:

Love how Government (& universities) in Australia crow about the amount of funding & number of grants they provide for "world-class research".

But these are tiiiiiny numbers! Basically 50 people working for 2–3 years. Peanuts🥜

More like "world-class underfunding, normalised".

Tweet from the Australian Research Council announcing the outcomes for the Linkage Projects 2023 (round 1) scheme. Just 50 projects were funded with $26 million in total.

It's harder to get funding for basic research projects than ever before in Australia.

The @arc_gov_au Discovery Projects scheme now has the lowest “success rate” ever: 16.3%.

Only 1 in 6 grants are funded.

Why? The funding available has plummeted.

Please help, Jason Clare MP❗️

Graph showing funded providing to Australian Research Council Discovery Projects, and the success rate of proposals, each year since 2002. The success rate has declined sharply since 2020, and is now at its lowest point ever (16.3%). The funding in this graph has been adjusted for inflation to 2023$.
