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...

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.

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.

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...

The 2023/24 El Niño event exhibited unusually weak extratropical teleconnections - Communications Earth & Environment Extreme sea surface temperature warming in the tropical Indian Ocean and Atlantic in 2023 suppressed the rainfall pattern induced by the 2023/24 El Niño, reducing its tropical and extra-tropical impac...

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.

Job alert: we are looking for a postdoc to join the Atmospheric Dynamics group in Oxford to study Arctic atmospheric dynamics. The focus is on energy transfers between scales and implications for predictability. More details here: tinyurl.com/yc6h4b35

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...

In this new paper we describe the trade off between forecast precision and accuracy. The smaller the location you are considering, the lower your forecast accuracy and to get acceptable accuracy we need to increase the spatial scale, the longer we try to predict

It was great to give an overview of my research so far at the RMetS Early Career conference earlier today! And great to hear about the variety of other research from early career scientists in the field.
