🚨 ‘Earth system engineers’ and the cumulative impact of organisms in deep time sciencedirect.com/science/arti... Honored to be among the long author list of this new paper out now in @cp-trendsecolevo.bsky.social that looks to bridge the ecosystem engineering and paleontological literature.

Ed Davey, "It's so frustrating, so infuriating that Nigel Farage gets such an easy ride from the media" "As he lies, as he divides, the BBC and others given Farage so much time and attention" "But they never hold him to account for all the damage he has already done" "The damage of Brexit"

One of the weirder oceanic things is Whiting Events, when the sea turns milky white with little aragonite crystals. They were first recognized in the Bahamas, then in the Persian Gulf, we found indications in the Med, and now reported in the Red Sea. 🧪🌊 Link: onlinelibrary.wiley.com/doi/10.1002/...

I hate it when people compare the amount of heat the ocean has absorbed to the power of atomic bombs dropped on Japan. It’s gruesome and not relatable. As my Japanese PhD student said when he heard the comparison, “It’s not a good memory for us.”

Ed Davey, "I'm afraid Nigel Farage should be apologising for helping cause this problem in the first place" "Before Brexit we didn't have a small boats problem because we had 27 return agreements with EU countries and we could return people" -Maybe we should call them Farage's Brexit Boats

Nigel Farage should apologise for his role in causing the small boat crisis, Lib Dem leader Sir Ed Davey has demanded www.mirror.co.uk/news/politic...

Power is the rock on which truth founders. The mainstream media, with a few exceptions, is a single-issue lobby group, whose purpose is to assert the rights of capital. Here's what I've learnt about the industry in 40 years in journalism. www.theguardian.com/commentisfre...

We are psyched about this as the ice ages are cool (sorry!) - but also as figuring out these processes by which the ocean took up 100s of gigatonnes of CO2 from the atmosphere in the past may help us better understand the controls on its capacity for carbon uptake in the future… 📈🌊

This likely acted in concert with other processes (changes in winds, circulation, sea ice, iron) to draw down CO2 during the ice ages. It can also explain why biogeochemical records from the North Pacific and Southern Ocean share similar structure (Haug & Sigman‘s “polar twins” 👯)

Notably, this is achieved without any change in Southern Ocean upwelling, sea ice or iron supply - it’s simply the result of having less carbon in the upwelled water.

The consequence - shown here - is that less CO2 would be delivered to the Southern Ocean. This by itself reduces Southern Ocean CO2 outgassing by as much as 50%.

In previous papers we and others have shown that these intermediate depth N Pacific waters were better ventilated during glacial periods (e.g. figure here from Rae 2020 and see also Rafter 2022 and Keigwin 1998 among others!) www.science.org/doi/full/10....

Part of the inspiration for this study was an interesting paper by Haidi Chen showing that much of the CO2 outgassed in the Southern Ocean today is sourced from the intermediate depth North Pacific. As these waters are old and CO2 rich they have huge outgassing potential (red colours below).

Another Tory has joined Reform you say? Why it would almost appear as of Reform were not an insurgent force of outsiders but … dare I say… the same old shit in a different package… by which I mean unutterable Tory wankers.

I've written to Keir Starmer, Kemi Badenoch and Nigel Farage, urging them to join me in condemning Elon Musk's dangerous remarks inciting violence yesterday. As leaders, we must stand together and make clear Musk will face serious consequences for these actions.

Must happen

I’m a broken record on this, but — there are so many examples of famous people radicalised by midlife career/personal knockbacks. Ant Middleton was on yday’s march. He got done for tax offences and lost his TV work. Now he’s mates with Tommy Robinson.

The future - just like history - is comprised of layers of possibility, cycling outwards from now in ways we can barely imagine. New life, old life, ancient life. Last week's rains give the ferns renewed autumnal life that echoes the ancient rivers that formed these rocks.

Our next #mesocosm study has started. Over the coming weeks, international researchers led by GEOMAR will conduct an experiment in closed marine tanks on the coast of Gran Canaria to investigate the effect of various methods of ocean alkalisation on the marine ecosystem www.geomar.de/en/news/arti...

Appalled by the violent scenes of police being attacked at the Tommy Robinson rally today. Those responsible should face the full force of the law. These far right thugs do not speak for Britain.

NEW: In July, we discovered the third-known interstellar object. It’s now erupting all sorts of stuff, from cyanide (normal) to nickel (weird). And as one source put it: “If it is an alien spaceship, it’s done a really good job disguising it as a comet.” www.nationalgeographic.com/science/arti...

Well this is very interesting!

Could we please stop pretending that the flags being hung from streetlamps or painted on roundabouts are innocent expressions of patriotic pride? This is the far right marking out its territory. It uses these flags to intimidate its traditional victims and opponents. 🧵1/3
