How's this for a feedback loop?
Ice sheets build up lowering sea level → reduced water load leads to increased mid ocean ridge volcanism after a 10-20 kyr lag → volcanism releases iron → iron causes plankton blooms → atmospheric CO₂ goes down → ice sheets build up

Ocean iron fertilization from enhanced mid-ocean-ridge volcanism due to ice-age sea-level falls - Nature Geoscience
Increased hydrothermal iron inputs from mid-ocean ridges, triggered by ice-age sea-level falls, supported higher surface primary productivity during the last two glacial terminations, according to pro...

Multnomah Falls cascades down 620 feet of flood basalts from the Grande Ronde Formation. Around 16 million years ago volcanism covered this region in thick lava flows. Today springs, snow melt, and runoff from Larch Mountain erode away at it. Multnomah Falls east of Portland, Oregon, 21 Nov 2015.

For you Venus fans following the #planetaryscience feed. And for you volcanism fans. A review of volcanism on Venus. 👇
New Paper Published. I am incredibly proud of this one. I agreed to this review when I was the branch chief of research and thought I could get the paper done in about 6 months....then multiple job shifts happened and the paper was submitted just over a year and 6 months after I said yes. (1/4)

this is amazing- possible present day volcanism?
We’re pretty sure this dark ash is made and released by volcanoes. Over time, either the wind blows the dark ash around to cover Mars’s light coloured surface, or the wind blows away the light dust to reveal the dark ash below.

be the ruinous volcanism you wish to see in the world
Back in the day, Earth’s ruinous volcanism almost sterilized the planet. Fortunately for living things, Earth gradually drew the excess carbon dioxide deep into its rocky bowels, and the planet cooled back down.
Why Is Venus Hell and Earth an Eden? | Quanta Magazine
A team of scientists has investigated how Earth’s twin became so inhospitable, and whether the same will happen to our planet.

Charon and the Moon look similar for similar reasons! Ancient surfaces (pockmarked and gray) that show geologic evidence for a semi-global volcanism event that happened after the heaviest part of impact history, and filled lowland areas with smooth plains -- liquid rock for the Moon, water on Charon
Kind of struck by how much this part of the moon looks to my untrained eyes like Pluto's much smaller moon Charon (which is also tidally locked). #ArtemisII

Volcanism Could Lead to Less, Not More, Atmospheric CO₂
The atmospheric concentration of carbon dioxide temporarily fell by 50% immediately preceding a period of intense volcanism, likely because of increased weathering, new results reveal.

Cryovolcanism is really very simple - what if volcanism, but with ice! - but explaining it any further requires delving into why and how volcanism but with ice would happen, and that's where all of us get into trouble.

Though volcanism is usually associated with an uptick in atmospheric CO2, periods of intense volcanism in the late Paleozoic happened alongside decreased CO2 concentrations 🧪. eos.org/articles/vol...
