Last year, Helen led landmark research alerting the world that the #PlanetaryBoundary for ocean acidification has now been exceeded, bringing global attention to the urgency of the situation we now face.

Pushing closer to catastrophe: Seven of nine planetary boundaries breached A worrying new report reveals humanity has breached the 7th of 9 critical planetary boundaries, with severe consequences for Earth’s life support systems.

Humanity has breached the seventh of nine critical planetary boundaries. The newly breached #planetaryboundary is ocean acidification, caused by excess carbon dioxide from #fossilfuel emissions.

"Holding on to 1.5°C is not a goal or target.
It is a limit, a #PlanetaryBoundary

Above 1.5°C we enter, with high certainty, the terrain of dangerous #ClimateChange.
() we have to do everything we can to limit warming below 1.5°C, even if we temporarily exceed it in a period of overshoot"

Humans Just Pushed Earth across Another ‘Planetary Boundary’ Earth has breached a critical boundary for ocean acidification, with potentially grim effects for ocean ecosystems and human livelihoods

More than half of the world’s land area is in a precarious state, according to a new study mapping the #PlanetaryBoundary of functional biosphere integrity - in spatial detail and across centuries. 38% of global land is already in the high-risk zone. 👇

oceans acidified I've covered ocean acidification many years ago, when it was beginning to emerge as a threat to corals and other calcifying sea organisms, and I've written about the planetary boundary concept (most recently, when chemical pollution was found to have exceeded the boundary). Thus the new research suggesting that ocean adicification is also outside the planetary boundary (as the seventh of the nine parameters in the original planetary boundary paper) presented a good opportunity to visit both issues in one go. My feature is out now: **Oceans acidified beyond boundary** Current Biology Volume 35, Issue 15, 4 August 2025, Pages R739-R741 Restricted access to full text and PDF download (will become open access one year after publication) Magic link for free access (first seven weeks only) See also my new Mastodon thread where I will highlight all this year's CB features. My mastodon posts are also mirrored on Bluesky (starting 22.2.2025), but for this purpose I have to post them again, outside of the thread. (I think threads only transfer if the first post was transferred, so once I start a new thread it should work.) Last year's thread is here . The cover image is not really related to my article, but to me it also symbolises the interaction between the oceans and the atmosphere, because: "Bluebottles or man-o'-war, cnidarians in the genus Physalia, use a gas-filled float and sail to catch the wind and sail the ocean surface." Cover of Current Biology, vol. 35, issue 15, 2025.
