Agrotóxico: seguro para quem? Ciência Suja · Episode

Este episódio novo do Ciência Suja está excelente. As queridas Carla Ruas e Silvia mergulharam nos Monsanto Papers e acharam MUITA ciência suja por lá. Vale escutar!

Hydropower Is Getting Less Reliable as the World Needs More Energy

It should go without saying that a world w/ more erratic precipitation is less suited for hydropower (imminent deadpool at Glen Canyon being exhibit A, though unmentioned in this story). Let's not build thousands more dams that will be obsolete almost from the jump.

Gladys Mae West obituary: mathematician who pioneered GPS technology She made key contributions to US cold-war science despite facing huge barriers as a Black woman.

No joke: I got angry hate mail today for writing an obituary of a Black woman scientist—because the person felt she did didn’t deserve the recognition.

Which just makes me want to share it again: www.nature.com/articles/d41...

These fossils have been chipped out of the ground over decades, but we finally managed to date them thanking to the flip-flopping of the Earth's magnetic field. And they date right from the time when the common ancestor of these three lineages would've been kicking around. 🧪

The world's biggest earth science conference is happening right now, and there are literally hundreds of presentations involving NCAR people. It's impossible to understate how central the lab is to the climate and weather science enterprise

It is hard to overstate how critical @ncar-ucar.bsky.social is to climate science in the US and around the world. It's the beating heart of our field. Generations of scientists have trained there, and almost everyone I know relies on deep collaborations with NCAR scientists. It's end is unthinkable.

Most of the scientists at the nonprofit that I cofounded, including my two cofounders, came from NCAR. It’s hard to overstate the importance of this place for climate science.

Fire Encroaches on One of the Amazon’s Most Pristine Indigenous Lands - Eos New research shows how recurring wildfires in the buffer zones around Brazil’s Vale do Javari may undermine one of the Amazon’s last great refuges for isolated Indigenous peoples.

Wildfires in rainforests threaten public health as well as ecology.

What happened at COP30? 4 science take-homes from the climate summit COP30 negotiated efforts to protect forests and ramp up financial packages for climate action, but with one glaring omission: a road map to cut fossil fuels.

#COP30 delivered climate finance and adaptation progress but no #FossilFuel phase-out plan, leaving ambition far behind science.

Here are some of the outcomes from the UN climate summit in Belém, Brazil.

Here are 3 big ideas to combat climate change, with or without COP As action from the U.N.’s huge COP30 international meeting falls short, smaller groups are banding together to find ways to fight climate change.

As CO2 Levels Rise, Old Amazon Trees Are Getting Bigger - Eos New data show resilience among the rainforest’s giants, though scientists warn that nutrient limits and rising heat could end the trend.

Carbon emissions are helping make older trees in the Amazon bigger. But “it doesn’t mean carbon dioxide is good for the forest," says Adriane Esquivel-Muelbert @camplantsci.bsky.social. "What we’re seeing is resilience, not relief.”

Covering Public Support for Government Climate Action Explore how the global majority not only cares about climate change, but wants their governments to “do more” to address it.

Story Idea: Study after study has shown that the vast majority of people, 80-89%, want governments to “do more” to address climate change. Understanding who these people are and why gov't action doesn’t align with the overwhelming public interest are all rich territory for reporting. #the89percent

Ricos no Brasil: 'brasileiro é obcecado por ricos por crença ilusória na mobilidade social', diz antropólogo que se infiltrou na elite - BBC News Brasil Autor de livro 'Coisa de Rico', antropólogo Michel Alcoforado se infiltrou entre super-ricos para estudar as diferenças de classes sociais no Brasil.

"Precisamos inventar um país em que mais pontes sejam possíveis e menos muros necessários para viver em paz. O grande problema da sociedade brasileira é acreditar que a harmonia só existe quando há grades, muros, vidros blindados, classe executiva, VIP, VIPão exclusivo." www.bbc.com/portuguese/a...

‘Computing is a Black people’s thing’ Passionate about making smaller and more efficient semiconductors, physicist Sonia Guimarães is a relentless voice for equity in Brazilian science.

Great to talk to Prof. Guimarães for @nature.com and share her research and advocacy for women and girls in #STEM. So much we don't know about the historical contributions of Black people to science!Thanks for your careful editing, @kendallsciwrite.bsky.social! :)

Good reporting on an attribution study from @nature.com:
🫠 Emissions from each of the 14 biggest #fossilFuel Firms made >50 heatwaves otherwise near-impossible
📈 Exxon & Aramco made 51 #heatwaves ≥10,000× likelier
🔥180 companies caused ~½ the rise in intensity (forest loss most of the rest)

Top US Energy Official Lobbies for Fossil Fuels in Europe - Inside Climate News European climate experts say the pro-fossil fuel arguments are based on climate disinformation.

As U.S. Energy Secretary Chris Wright lobbies for more fossil fuels in Europe, climate experts are warning his pro-fossil fuel arguments are based on disinformation, including a misleading climate report his department published this summer.
