The billion-year reign of fungi predated plants and made Earth livable. Ancient fungi may have partnered with algae, recycling nutrients, breaking down rock, and creating primitive soils. Far from being silent background players, fungi were ecosystem engineers. https://www.sciencedaily.com/releases/2025/10/251001092208.htm #science #biology #AncientHistory #fungi #HabitablePlanet

If Hycean Worlds Really Exist, What are Their Oceans Like?

Astronomers have been on the hunt for a new kind of exoplanet in recent years – one especially suited for habitability. They’re called hycean worlds, and they’re characterized by vast liquid water oceans and thick hydrogen-rich atmospheres. The name was coined in 2021 by Cambridge astronomer Nikku Madhusudhan, whose team got a close-up look at … Continue reading "If Hycean Worlds Really Exist, What are Their Oceans Like?"

A behavioural crisis is driving ecological overshoot and threatens the fabric of complex life on Earth

"We explore three drivers of the behavioural crisis in depth: economic growth; marketing; and pronatalism. These three drivers directly impact the three ‘levers’ of overshoot: consumption, waste and population...The evidence indicates that anthropogenic ecological overshoot stems from a crisis of maladaptive human behaviours...We have in place to deliver a framework for shifting social norms and other necessities for addressing the behavioural crisis."
https://journals.sagepub.com/doi/10.1177/00368504231201372

"Where discussion of climate often centres on carbon emissions,
a focus on overshoot highlights the materials usage, waste output and growth of human society, all of which affect the Earth’s biosphere. Just one-quarter of the world population is responsible for nearly three-quarters of emissions...Solutions that do not tackle the underlying drivers of our growth-based economies will only exacerbate the overshoot crisis."

"The system is driving us to suicide. It’s conquest, entitlement, misogyny, arrogance and it comes in a fetid package driving us to the abyss.”

Over the last ten years, the promise of a #GreenClimateFund has been a big piece of the puzzle when it comes to global climate agreement. Arguably, the #ParisClimateAgreement reached in 2015 and signed by every nation in the world (bar war-torn #Syria) in 2016 was one of the biggest steps forward in international cooperation over a global crisis in the history of humanity (while still being thunderously inadequate to the scale of the #ClimateCrisis). After decades of arguing and partial steps, 2015 was the first time a major agreement had been reached that included all the major polluting nations promising to reduce their carbon emissions towards a goal of at least somewhat #HabitablePlanet

And the pledge of a US$100bn/yr Green Climate Fund was widely acknowledged in international negotiations as a major enabler of this historic Paris Climate Agreement. Though still far from adequate (some estimates said that to be fair, it really ought to have been five times as large), it was nonetheless a solid first formal step towards recognising the massively unequal responsibilities of various nations when it comes to causing planetary #ClimateDisruption.

A #RisingTide of people seeking to put spokes in the wheels of the the #DeathMachine putting corporate profits before a #HabitablePlanet.

#Solidarity and #gratitude to the hundreds of people who used kayaks and their bodies to blockade the world's busiest #coal port for 32 hours this weekend, and to the thousands who supported them, and to the millions who cheered them on, and to the billions for whose sake they were acting. This was a taste of an unstoppable force of collective #courage, #care and #commitment

Colors of a Habitable Exoplanet

When it comes to planetary habitability, it is all too easy to let our assumptions slide past without review. It’s a danger to be avoided if we want to understand what may distinguish various types of habitable worlds. That’s the implication of a presentation at the recent Europlanet Science Congress (EPSC), which
