Bad news from the EU.Regressions from the most climate progressive region on the planet.Highly concerning, especially with Trump in power.Also, the FinancialTimes today published that 79% of solar energy projects globally are taking place in China.What is changing? www.politico.eu/article/cent...

1/🧵To my non-Spanish-speaking colleagues: A quick thread on the new Advisory Opinion OC-32/25 from the Inter-American Court of Human Rights (IACtHR) on Climate Emergency and Human Rights. A landmark moment for climate law in Latin America & the Caribbean.👇

New research in Nature strengthens the case for holding fossil fuel companies accountable for climate-related damages. By Callahan & Mankin, the study links emissions from 111 coal, oil & gas firms to trillions in economic losses from extreme heat. 1/n www.nature.com/articles/s41...

“The consequences of these decisions have already extended beyond U.S. borders,” writes @pedrocig.bsky.social. How the U.S. isn’t the only country paying the price for climate denialism 🌏:

As diverse communities around the world remember the legacy of Pope Francis, I would like to share some insights into one of his most significant legacies, particularly in the realm of climate justice: Laudato Si. 1/n 👇🧵

For nearly 15 years the US Dept of Interior's Climate Adaptation* Science Centers have supported hundreds of scientists studying how ecosystems respond to climate change & pollution, invasive species, sustainable wildlife & wild lands management, and more. Now the admin wants to cancel them all.

Thanks for the space @conversationalist.org !

“Effective climate action requires not only environmental responsibility but also a commitment to global justice, equity, and shared prosperity. The current U.S. approach only undermines these principles...” More by @pedrocig.bsky.social:

Trump is back—and so is climate denialism. In this piece for The Conversationalist , I explore how Trump’s return is impacting global climate efforts ahead of COP30. Read it here: conversationalist.org/2025/04/11/i...

Interesting litigation development in protecting biodiversity. 👇 www.theguardian.com/environment/...

The SCOTUS (with dissenting opinions of Judge Alito and Thomas) has allowed climate lawsuits against major Texas oil companies like Exxon and Chevron to proceed. This could set a significant precedent for holding corporations accountable for their role in climate change. apnews.com/article/supr...

Just for putting things in perspective. Last year at the COP29,developed countries committed to mobilising $300 billion annually by 2035 to support developing nations climate mitigation and adaptation efforts. In one year, the US defence budget tripled the climate finance goal agreed at the COP29.

The acceleration of climate inaction is a growing concern. Denialism is impacting policies and decisions in the US, potentially influencing other stakeholders to reduce climate ambition in alignment with current directives. www.nature.com/articles/d41...

Carbon removal is crucial for net zero, but misusing it risks failure. Most 1.5°C pathways need all sustainable CDR for hard-to-abate emissions & overshoot. Yet, it's often used elsewhere, driving up costs. Nice insight in this paper. www.nature.com/articles/s41...

Last week, @science.org published two articles on Trump's new presidency: 'Climate Deja vu' on Trump's decision to leave the Paris Agreement. (www.science.org/doi/10.1126/...) 'A world less safe and secure' on Trump's decision to leave the WHO. (www.science.org/doi/10.1126/...) Please,read both.

President Trump announced today that he would seek to remove the US from the #ParisAgreement. “Such a move is in clear defiance of scientific realities and shows an administration cruelly indifferent to the harsh climate change impacts that people in the US and around the world are experiencing.”

11AM: How bad could the new administration be? 4PM: And Elon did that how many times?

States, local governments, civil society, companies, and communities are essential to implementing the Paris Agreement. When federal leadership is absent, these stakeholders must and will step up and lead the way.

Tomorrow starts 4 complex years of resistance against the power of those who want to destroy ecosystems, the climate, human rights, international law, and democracy.

This insightful paper proposes a theoretical framework examining how aversion to disadvantageous inequality weakens motivation for climate cooperation across the broader population. Climate decisions and policies require considering climate equity. www.nature.com/articles/s44...

It's been a while since I last posted here. This year, I’m looking forward to continuing discussions on climate change, particularly around climate law, climate equity, corporate net-zero targets, and urban climate action.

Pleased to say that my article on #COP29 has just been published by the Law Society of Scotland: tinyurl.com/dpd4jbws. I take a pretty dim view of the proceedings. Do tell me where I got it wrong!

After the first week of state submissions to the ICJ on the climate change advisory opinion, key tensions between developed and developing countries arised. Here’s a breakdown of some of the issues: 🧵

The oral submissions made by countries this week to the ICJ regarding the advisory opinion on climate change are inspiring. This historic and unique procedure deserves much more media attention than it currently receives.

Next week, the ICJ begins hearings on the advisory opinion on climate change. While expectations are tempered—given the ICJ's traditionally cautious approach—it will be relevant to see the positions countries present in comparison with their COP29 stances on,for instance,climate finance.

It would be more accurate if newspaper headlines read, 'Rich countries fall short of the $1 trillion needed by vulnerable nations to address climate change,' rather than celebrating a $300 billion commitment that leaves the critical funding gap unaddressed.

To understand how consensus at COPs differs from unanimity, please type in google: “Bolivia rejects Cancún Agreement” and “Rule 42 of UNFCCC procedural rules.” Bolivia’s COP16 dissent showed consensus allows adoption despite objections, as unanimity isn’t required.

1/ The latest climate finance agreement shows some progress compared to previous drafts. While not perfect, it includes some key advancements worth noting. 🧵

I believe it's positive to see the 1.3 trillion in the #NCQG decision. Having it as a soft goal to be reinforced in subsequent COPs gives the chance to push for it. At the COP30 the call for the 1.3 trillion should become a goal. That's the challenge and the opportunity that this decision gives.

The recent NCQG text on climate finance defers decisions to the future. #COP29

Carbon markets of Article 6.4, after 9 years of negotiation, adopted.

This paper, published in the last issue of the npj climate action of Nature Magazine, is key to understanding the current discussion and obstacles that Parties are having for achieving an agreement at COP29. Many thanks, Andreas Sieber and Iskander Erzini Vernoit, for this clarifying piece.

300 billion of climate finance by 2035 is a slap in the face, especially considering the increasing climate impacts that developing nations will have to face by then.

In 2023, according to the World Bank, the global GDP was around 105 trillions. In COP29, developing nations are asking for 1.3 trillions annually by 2035 for financing decarbonisation, adaptation and loss and damage. Around 1% of the global GDP. Not too crazy, no?

Tomorrow around 10.00 am. will be the closing plenary of the COP29. Still parties and organisations with certain levels of hope on an agreement for the NCQG on climate finance.It is difficult to have hope, but I'm sure there are many negotiators still trying to achieve the best output towards COP3O.

Influential paper by @natureportfolio.bsky.social discussing how climate litigation impacts firms' value: "Financial markets view such litigation as a significant financial risk". 👇 www.nature.com/articles/s41...

👇

No cover text. No agreement on quantum. No agreement on ambition. Fossil fuel inclusion blocked by oil states. With all this in mind—though I hope to be proven wrong—substantive progress at COP29 seems unlikely.

OUT NOW! The latest Climate Change Performance Index 2025 paints a mixed picture: While 61 of 64 countries have increased the share of renewables in their energy mix, too many countries are still clinging to prolonging the fossil fuels business model. 🔗 ccpi.org

It was a pleasant surprise to see the Dutch 🇳🇱 Appellate Court cite Brazil’s Climate Fund decision 🌳⚖️ in its discussion of European case law on human rights and climate change in the recent Milieudefensie v Shell ruling. 🌍🔥 Here is what the court said:

I made a starter pack for those working on global climate change litigation. Who else should be here? go.bsky.app/RzfDPjB

Climate finance and the international financial system reform as relevant elements of the G20 declaration. Also, an explicit call to reinforce multilateralism (before Trump arrives) www.gov.br/planalto/pt-...

Why is the G20 Summit scheduled during the second week of COP29? Doesn’t this split global focus at a time when unified climate action is crucial? Opinions?

Staying below 1.5°C is increasingly unlikely, and a new Nature paper adds weight to the urgent call for decisive decarbonization and credible, durable carbon removals.
