📢Global Carbon Budget 2025📢 Fossil CO2 emissions continue to rise in 2025 while the terrestrial carbon sink recovers to pre-El Niño strength. The key findings are covered in two reports this year: * ESSDD (preprint): essd.copernicus.org/preprints/es... * Nature: www.nature.com/articles/s41... 1/

Components of the global carbon budget and their uncertainties as a function of time bit.ly/GCB2025-b Friedlingstein, P. et al. (2025). Global Carbon Budget 2025. Earth System Science Data Discussion, (Under Review). DOI:10.5194/essd-2025-659

New in @science.org: Calcifying plankton #coccolithophores, #foraminifera & #pteropods quietly drive the ocean carbon pump. Their traits (incl. “shallow dissolution”) are missing from many climate models. Time to put CaCO₃ back in the picture. #ClimateScience 🌊 doi.org/10.1126/scie... #protistsonsky

In Science, a new reconstruction of global sea levels spanning the past 4.5 million years reveals that oceans once stood up to 20 meters higher than today and links the waxing and waning of ancient ice sheets to shifts in Earth’s temperature and carbon dioxide cycles. https://scim.ag/42STXUm

Today, we published a study long in the making on how upper and subsurface tropical Pacific waters responded (and maybe will adjust) to warmer global climate. Here’s the story of how we got here after 15 years. many authors but shout out @jfarmersalmanac.bsky.social 🌊 www.science.org/doi/10.1126/...

The Rainfall Observers Over the past three centuries, thousands of people across the British & Irish Isles have recorded rainfall, often every day for decades. Here we recognise some of the individuals who made particularly important contributions. rmets.onlinelibrary.wiley.com/doi/10.1002/...

🚨New work🚨 led by Ph.D. student Dipesh Chuphal (IIT Gandhinagar), shows that the recent drying of the Ganga River basin is unprecedented in 1,300 years—more severe than historical famines. This ~multidecadal drying appears forced, but many models do not capture it. ☔️ 🌧️ www.pnas.org/doi/10.1073/...

"Before the 7 October atrocity about 40% of its land was farmed. Despite its extreme population density, Gaza was mostly self-sufficient in vegetables and poultry. But last month, just 1.5% of its agricultural land now remains both accessible and undamaged." www.theguardian.com/commentisfre...

There's a really nice explanation (with clear graphics) in this @quantamagazine.bsky.social article of why most molecules in the atmosphere (oxygen & nitrogen) don't act as greenhouse gases, but a lot of the far less numerous ones (like carbon dioxide and methane) do. A great teaching aid :)

Let's talk about how "ammonia" (NH₃) gets its name 🧪. Along the way, we'll talk about Alexander the Great, ancient Egyptian gods & a Roman misunderstanding. Let's start with these giant CASTLES made for PIGEONS in Siwa, Egypt, a tiny desert town built around an oasis, with 2 dry salt lakes nearby.

Why are these extinct cephalopods called "Ammonites"? The Egyptians worshiped a fertility & weather god called Amon, or Amon-Ra, often depicted as a man with the head of a ram. The Phoenicians imported this god into their deity 'Baal Hammon'... (🧑‍🎨: Masato Hattori, SciLibrary)
