Cutting methane emissions is a smart, fast way to tackle climate change. This satellite was such a crucial tool for tracking who’s emitting methane and helping to hold them accountable. It’s a sad day.

I've been a fan of Nature's newsletter 'Anthropocene' for a while now and was so happy to see my @chemistryworld.com article on period products featured in today's edition 😊 Read the story here: www.chemistryworld.com/features/how...

In many ways, the debate around glyphosate highlights long-standing scientific questions. How should we weigh evidence, and how do we calculate risk overall? @broadwithp.bsky.social gets into the weeds of the controversy in this article, but that's not all we have on glyphosate this week...

UK writers, anyone else having trouble with logging into ALCS?

The glyphosate debate: nice to see our own @hmetcalfe1.bsky.social quoted in this in-depth feature by @barbarapinho.com www.chemistryworld.com/features/the...

In 2023, the EU approved glyphosate for another decade of use. This got me thinking: how does this decision affect British farms in a post-Brexit Europe? I explore this and more in my latest feature for Chemistry World.

📢 Methane emissions are underreported - by a lot A new study finds that inconsistencies in carbon accounting standards lead to a massive underreporting of methane emissions - up to 3.3Gt CO₂ equivalent, depending on the metric used. 🔗 www.nature.com/articles/s41... #Climate #Methane #SciComm 🧪

Pesticides Harm More Than Pests A large-scale analysis of 1,705 studies shows that pesticides negatively impact non-target plants, animals, and microbes - raising concerns about biodiversity loss. 🔗 www.nature.com/articles/s41... #SciComm #Biodiversity #Pesticides 🧪

🐟 Cod shrinking from centuries of fishing A new study reconstructs 1100 years of Atlantic cod fishing. Viking-era cod were 25% larger & lived 3x longer than today. Overfishing drove size & age declines - not climate. 🔗 www.science.org/doi/10.1126/... 🧪 #Ecology #Fish #SciComm

🌍 Wetlands & methane: a warming cycle Wetlands are releasing more methane due to rising temperatures, about 6–7 million tonnes more each year since 2000. Climate change is fueling this increase, making it harder to slow global warming 🔗 bg.copernicus.org/articles/22/... #SciComm #ClimateCrisis 🧪

🐟💧 PFAS and Cancer: A Link in Drinking Water A new study connects PFAS ('forever chemicals') in US drinking water with cancer risks. Researchers estimate up to 6,800 yearly cases are now tied to these contaminants. 🔗 doi.org/10.1038/s413... #PFAS #SciComm 🧪 #Health

NEW: 2024 has just been confirmed as the warmest year on record, and the first to breach the 1.5C threshold. We used a ridgeline (Joy Division inspired) chart to visualise daily temperature anomalies since 1940. 2024 clearly stands out with 100% of its days above 1.3C and 75% above 1.5C.

‘Hollywood is just content now!’ Well then watch non-English-language stuff. Watch independent films. Watch stuff made for $10m max. Watch shorts. Watch guerrilla documentaries. Watch experimental filmmaking. Watch kooky animations. It’s still film if it wasn’t made in California for $100m.

Really not a fan of "in-person conferences are the best because it let's everyone get together and chat". Sure - undeniably, it provides networking opportunities, but to not offer hybrid options makes it inaccessible for many. And let's not pretend those "chats" don't benefit some over others.

This is really interesting! Weird, but interesting The author of this @technologyreview.com article copied every story from the 125th anniversary issue of MIT Technology Review into the AI tool, and let the system generate a 10-minute podcast of the results I wasn’t ready for the final result

Vanuatu's statement on the outcome of #COP29 sums it up nicely: “It’s not enough. It was never going to be enough.”

Since our microbiomes can have such a large impact on our body’s function I try to think of microbiomes as part of an organism And therefore I find it weirdly comforting knowing that some of my deceased loved ones’ microbial communities live on in me 🤷🏼

This article highlights some of our work over the last few years on NW India's agricultural fires, a seasonal and episodic source of regional air pollution. It was great to talk to Karishma Mehrotra at WaPo, and these anecdotes from farmers are especially important. #fires 🔥 #AirPollution 💨 #India

2023 was one of the worst years for wildfires in the EU in over two decades. 🔴 500,000 hectares of natural lands affected, 🔴 The largest single fire in the EU since tracking began, 🔴 ‘Megafires’ are on the rise and fire season prolonged. → europa.eu/!KyvRhh

Meltwater from Greenland and the Arctic is weakening ocean circulation, speeding up warming down south Explainer from Laurie Menviel and Gabriel M. Pontes, off the back of their new article in Nature Geoscience ⬇️ @ccrc.bsky.social UNSW @clarepeddie.bsky.social theconversation.com/meltwater-fr...

Summer UK temperatures have warmed faster than global average temperature. But the very hottest days have warmed 4x faster than the global average, especially in south-east England. Global warming is not "just" 1°C or 2°C. The effects of climate change are non-linear, especially for extremes.

And secondly a deep dive into what historians of future ages will make of us, living as we do right now, surrounded by ephemeral data. Will there be anything left to know what we cared about/how we lived? And who gets to decide what gets saved? www.technologyreview.com/2024/08/19/1...
