New model correction improves predictions of Antarctic ice shelf melt - ACEAS A new study led by ACEAS PhD researcher Claire Yung from ANU introduces a correction to ocean models that could significantly improve global sea-level rise predictions from Antarctic ice shelf melt.

🌏 Better models = better climate predictions.

A new paper led by ACEAS PhD researcher Claire Yung (ANU) shows how a refined equation used in ocean models can significantly improve the accuracy of Antarctic ice shelf melt predictions.

New paper: we show that variability in the Zonal Wave-3 mode - an atmospheric pattern made up of three pairs of cyclones and anticyclones circling the Southern Hemisphere - does influence the formation and export of dense waters around Antarctica over multiple years.

Stratified suppression of turbulence in an ice shelf basal melt parameterisation Abstract. Ocean-driven basal melting of Antarctic ice shelves is an important process that affects the Antarctic Ice Sheet, global climate and sea level. Basal melting is controlled by small-scale pro...

Our paper on a new ice shelf basal melt parameterisation is out! tc.copernicus.org/articles/19/...
Small-scale processes in the ocean drive ice shelf basal melt, and large-scale ocean models can’t resolve these processes. Therefore, models use melt parameterisations, but these can still be improved.

For so long, fossil fuel projects have said their contribution to climate change is "negligible".
Turns out that's wrong.
Our research in NPJ Climate Action proves it.

Australia to woo US’s ‘smartest minds’ disfranchised by Trump research cuts

Stand Up for NOAA Research – The Time to Act is Now The AMS is a global community committed to advancing weather, water, and climate science and service.

The 2026 budget passback plan calls for eliminating NOAA Research, the scientific backbone that keeps weather forecasts, alerts, and warnings accurate and effective. This would have disastrous consequences.

Read the AMS statement, in partnership w/ @nwas.org: bit.ly/4cz2RtC

It's even worse than removing the grant funding for university research (in groups like mine at UC Irvine). NOAA labs and cooperative institutes collect the climate data we use, develop the predictive weather and climate models, and train the students we hire.

This demolishes U.S. climate research.

Graph of science funding of NASA from 1980 until present with estimated 50% cut included. This drops NASA Science to under $4B. Image source: Casey Dreier/The Planetary Society

Cuts to #science of >50% at NASA and >75% at NOAA would end US climate and space science research.
