Arctic sea ice has melted more slowly for the past 20 years, despite global warming, a study led by @markengland.bsky.social finds.

Climate modelling suggests this is due to ‘natural climate variations’ and will be followed by faster-than-average sea ice decline.

Temporary slowdown in melting of Arctic sea ice, study finds

Arctic sea ice has been melting at a slower rate for the past 20 years, despite human-induced global warming. This comes at a time of record warming, debates about whether global warming is accelerati...

Our recent paper @natgeosci.nature.com shows that over the Med, marine heatwaves are linked to subtropical ridges rather than atmospheric blocking, the typical cause of atmospheric heatwaves in central Europe.

The brilliant ECRs Giulia Bonino and Ronan McAdam led this work!

Our paper showing the differences between European and African weather forecast accuracy has appeared online. The results will not surprise meteorologists, but the international development community needs to hear this.

Weather forecasting in Africa needs to be done differently.

New paper from Richard Keane
rmets.onlinelibrary.wiley.com/doi/10.1002/...
Both physical and machine-learning (ML) models "perform better on smaller scales and shorter lead times at middle latitudes and on larger scales and longer lead times at tropical latitudes."

Mid‐Latitude Versus Tropical Scales of Predictability and Their Implications for Forecasting

We show that forecasts perform better in mid-latitudes on shorter scales, and better in tropical latitudes on longer scales (quantified here over Europe and Africa), with a ‘crossover’ at 5–7 days, f....

During 2002-22, the Antarctic lower stratosphere cooled, a sign of decreasing ozone. A new study showed that this cooling was driven by a slowdown of the atmospheric motion that transports ozone poleward. Removing this effect showed a continued healing of the ozone layer. 🌊🧪👍 doi.org/10.1029/2025...

Big El Niños 🌊 usually come with big 🌎 teleconnections.
The one in 2023/24 didn't. Why?
Rainfall anomalies in the tropical Pacific were suppressed due to greater warming in Indian and Atlantic Oceans.

The 2023-24 El Nino, despite being ranked the 4th strongest since 1979, exhibited an unusually weak teleconnection pattern. A new study showed that warm tropical Indian & Atlantic suppressed tropical Pacific rainfall response to El Nino, and thus was mainly responsible: 🌊🧪 doi.org/10.1038/s432...
