From Belém #COP30 to Paris #IPCC… Starting my AR7 journey. The First IPCC Leading Author Meeting is underway in Paris. For the first time, authors from all three working groups are meeting for a full week to review and assess the latest climate research...

When they announced that #COP30 would be in Belém and all the logistical problems that followed, I was convinced it was a bad idea... On 09/11 flying to Belém, the plane was packed with foreigners talking and laughing... as we approached landing, we could see the forest, silence took over...

Would you #COP30

On the opening day of #COP30 here in Brazil, we will be launching this year’s “10 New Insights in Climate Science” @futureearth.bsky.social , The Earth League & @wcrpclimate.bsky.social If you are attending COP30 in person, please reach out (agenda in the comments) 10insightsclimate.science

This is another webinar organised by @wcrp-clivar.bsky.social Marine Heatwaves Research Focus 🌡️ We will have two fantastic talks by Dr. Amandine Schaeffer & Dr. Neil Malan, followed by a Q&A session 🌡️ Please take a look at the details below on how to register 🌡️ August 25 2025, 23:00 UTC 🌊

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! 🌊Link in the comments.

🌊 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.

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

🌊🌡️ In this study published @natcomms.nature.com, we analysed the simultaneous occurrence of marine heatwaves with extreme events of high acidity and net primary productivity in the equatorial and South Atlantic. Why is this important? A short 🧵... www.nature.com/articles/s41...

New study by @rrrocean.bsky.social, @froeltho.bsky.social et al. shows that the co-occurrence of #MarineHeatwaves with extremes of high #acidity and low #chlorophyll concentrations increased dramatically over the past two decades in the equatorial and #SouthAtlantic. www.nature.com/articles/s41...

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! Mahalo to Christina Karamperidou & Malte Stuecker

We've just published a study @commsearth.bsky.social about the severe 2020 coral bleaching event in the tropical Atlantic caused by massive marine heatwaves 🌊🌡️🧵 Link: www.nature.com/articles/s43...

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. 🌊🧵

As a Brazilian born during the military dictatorship, I can say this film is also an analogy for what Brazil could have become had it not been for the dictatorship. A beachfront Brazil full of friends and laughter, books and art, cigars, whisky and celebrations… 🧵

Two-thirds of the Earth’s surface experienced record heat in 2024. See where and by how much – visualised #climatecrisis www.theguardian.com/environment/...

I am proud to have helped interpret this analysis, which highlights the impacts of climate change on land and the oceans 🌊 with great visualisation... 2/3 of the Earth's surface experienced record heat in 2024! lnkd.in/d4v9rRSB

🌊 This is the first of a series of webinars organised by @wcrpclimate.bsky.social CLIVAR Marine Heatwaves Research Focus 🌊 We will have two fantastic talks by Prof Shoshiro Minobe & Hirotaka Sato, followed by a Q&A session 🌊 See details below on how to register 🌊 March 3 2025, 23:00 UTC

🌊 Consider submitting an abstract to our Session JPCM09 Atmosphere, Land, Ocean and Cryosphere Compound Events Co-coveners Regina R. Rodrigues, Christian Franzke, Kai Kornhuber, Yueng-Djern Lenn Deadline: 15 Feb 2025 baco-25.org/new/sub1/sub...

And now the heat is on! We are heading for a 10-day heatwave. Not fun waking up at 6:00am with 27C already… Though with a beautiful sky!

Climate change will affect all of us! Two weeks ago it was my turn. Record-breaking rainfall in Florianópolis where I live reached 390 mm in 36 hours. A similar event in 1995, considered the worst extreme in history, was 165 mm in 36 hours. We @wwattribution.bsky.social have released a statement.

🌊 The Marine Heatwave Research Focus is a working group of WCRP-CLIVAR, chaired by Antonietta Capotondi and me. We just published this review paper, and many open questions remain about their vertical structure, prediction and projections… rdcu.be/d2Xh0

#COP29 Painel Nexus Oceano-Clima e Sociedade promovido pela Rede Clima, rede de cientistas ligada ao MCTI discutirá ações de adaptação e mitigação do oceano, incluindo o uso de finanças azuis e cooperação entre estruturas de governança e convenções para melhor apoiar a capacitação.

Momento de tietagem na #COP29… nossa ministra dos povos indígenas!

🌊 Join us tomorrow at our UNFCCC event on Ocean-Climate-Society at #COP29 (registration online required).

So it begins… I am here with the Brazilian science delegation to the running up to COP30. I hope we can do differently in Brazil, with science and people at the centre of COP30…

Esta quarta as 18:30 será a abertura da SEPEX na UFSC estarei em uma mesa redonda com o Sergio Sacani e Eslen Delanogare. O evento é aberto ao público e gratuito. Estão todos convidados!

Don’t forget to apply or submit your abstract! 🌊

In this article, @tomphillips.bsky.social mentioned that “Scientists attributed a 2023 drought that punished the Amazon to the natural climate phenomenon El Niño.” We did an attribution study (WWA) that shows climate change, not El Niño, main driver of the Amazon drought in 2023. Link below

From @meghier.bsky.social What means for us Brazilian scientists to have to rebuild our network… not easy… even before the ban… www.nature.com/articles/d41...

🌊Celebrating the Scientific Legacy of Klaus Wyrtki We are organizing a symposium and an ENSO Winter School 2025 to celebrate the 50th anniversary of two milestone events of early ENSO research that involved Klaus Wyrtki of the University of Hawaiʻi at Mānoa.

A few weeks ago, we released an attribution study about the fires in Pantanal, the largest wetlands in the world. In the last decades, the rainfall has decreased while temperatures are sore (left), fueling fires (right). @WWAttribution ✍️https://ow.ly/oKQs50STRfF

*LAST WEEK* submit your expert input & nominate co-authors for this year's 10 New Insights in Climate Science What key recent advances in climate change research should be raised to the attention of negotiators? futureearth.org/2024/01/22/e... @wcrpclimate.bsky.social @futureearth.bsky.social

Climate change increased the likelihood of the 2023 Amazon drought 30x El Niño contributed, but climate change also led to extremely high temperatures and increased water evaporation 🌎 In a 2° Celsius warmer world, similar or worse droughts will likely occur in the region every 10-15 years:

We just released the World Weather Attribution study about the role of climate change in the Amazon drought in 2023. The message is simple:   Climate change, not El Niño, main driver of exceptional drought in highly vulnerable Amazon River Basin. Link for the full report: lnkd.in/dKuanvKE

In this study by Da Nial, Niklas Boers & colleagues, we investigate the interplay between two tipping elements of the climate system: the AMOC and Amazon forest! A potential collapse of the AMOC could lead to cooler and wetter conditions in parts of Amazon and less rainforest conversion to savanna.

In my last post of the year, in retrospect, I started 2023 writing this guest post for @carbonbrief.org, in which I discuss how the South Atlantic is overcoming its history as an under-researched ocean.    The “Improper Ocean”… Check it out here: www.carbonbrief.org/guest-post-h...

In spite of all our problems and setbacks, Brazil is making history today at #COP28  with the first Indigenous head of a delegation Sônia Guajajara, Brazilian Minister of Indigenous Peoples!

The Brazilian version of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services “BPBES” released the SPM of the Special Report on Coastal and Oceanic Ecosystems. I’m proud to have coordinated Chap. 4 on the impacts of climate changes. www.bpbes.net.br/produto/diag...

A few weeks ago, I gave a talk at the Brazilian Academy of Sciences on the current situation in Brazil: severe droughts in the Amazon, floods in the south and heatwaves in the centre due to a strong El Niño in a changing climate...

El Niño, combined with climate change, has led to many extremes this year in Brazil. Learn more in this comprehensive article by @andre_biernath for BBC Brasil
