Mediterranean summer marine heatwaves triggered by weaker winds under subtropical ridges - Nature Geoscience

Reduced winds below subtropical ridges are a key factor in the initiation of summer marine heatwaves in the Mediterranean Sea, according to a statistical analysis of large marine heatwave events.

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!

🌊 Last day of the One Ocean Science Congress #OOSC heading to the UNOC3… lots of good science to back up our decisions. #ScienceForTheOcean

Thanks to @jpgattuso.bsky.social for leading this extraordinary meeting and @froeltho.bsky.social for chairing our session on extreme ocean events!

Recommended read: @al-jazeera-english.bsky.social ran a long-read about efforts led by Brazil’s Indigenous Maxakali community to protect and restore the rainforest in Minas Gerais.

With song and seed, Brazil’s Indigenous Maxakali confront climate change

The Atlantic Forest used to blanket Maxakali territory. But as the forest disappears, the group faces intense heat.

It was indeed a day of great learning from the discussion about the ocean climate nexus! 🌊

🌊🌡️The frequency and intensity of these triple compound events have increased dramatically over the past two decades, occurring practically every year since 2016. This threatens the capability of marine ecosystems to recover from these compound extremes. Example for the eastern equatorial Atlantic...

🌊🌡️The adverse effects of ocean warming combined with acidification on marine ecosystems can be mitigated by increased food availability. However, this is not possible when extremes of warming and high acidity co-occur with low net primary productivity, i.e., a decrease in food availability.

I just returned from Hawaiʻi, energised by two fantastic events at the Univ. of Hawaiʻi at Mānoa

The symposium celebrating the scientific legacy of Klaus Wyrtki & the ENSO winter school

I made new acquaintances, met old friends & learned a lot!

The increase in the severity of the marine heatwaves in the western tropical Atlantic is not accompanied by trends in the strength of the local drivers, suggesting that weaker forcing can lead to more devastating marine heatwaves as the global ocean temperature rises due to climate change.

The extreme warming during the summer/fall of 2020 led to the largest bleaching event recorded along the Brazilian coast, with 85% of stony corals and 70% of zoanthids areas bleached in Rio do Fogo.

Marine heatwaves are 5.1 times more frequent and 4.7 times more intense since the records started in 1982, with the 10 most extreme summers/falls in terms of marine heatwave cumulative intensity and spatial extension occurring in the last two decades.

The PIRATA committee is currently facing the challenging task of determining which buoys in the array to keep in the water. This decision will disrupt the long-term series established in 1997.

What a sad way to show that science has no borders.

For many years, I have been involved in the Prediction and Research Moored Array in the Tropical Atlantic (PIRATA) Programme, and I can attest to this. PIRATA is a successful collaboration among the US (NOAA), Brazil, and France. However, its data are assimilated and used by many across the globe.

I have been receiving the sad news about massive NOAA firing.

I cannot explain how important NOAA is for science globally. The data and model outputs generated by NOAA globally allow researchers from countries that don’t have the funding or capability to develop those to do their own science. 🌊🧵

These social reforms were considered too “communist” and deservedly a military coup backed by the USA to stamp them. The results were an ever-unequal and impoverished Brazil or Latin America… A situation that has finally got back to bite Americans' asses... pardon my language...

Regina R Rodrigues @rrrocean.bsky.social · Feb 23

The alleged reason for the coup was the social reform the then President Goulart proposed. You can guess the main points: land, education, and voting reforms, but mainly fiscal reform, which increased government regulation and stopped money evasion... the very reason we have now the Musks and Trumps

It is estimated that 434 people were killed, a small number when compared to the Argentinean & Chilean dictatorships. But it killed the very best people with political aspirations in Brazil. A vacuum that was filled gradually by the worst.
