A new study may have helped to explain how the ocean storage of carbon changes with sea level over the paleoclimate. When sea levels are high, ocean carbon sink drops leading to high atmospheric CO₂ which keeps temperatures and therefore sea levels high. #carbonsink #oceans #paleoclimate #CO2
Two studies show that the Arctic Ocean may have passed a tipping point leading to a near complete lack of fish. The first study reports on barren waters north of 82º while the second exposes the biochemical drivers. #climatechange #Arctic #seaice #tippingpoint #biochemistry #foodchain #carbonsink
A new study has assessed the time horizon for the Earth Energy Imbalance to stop rising and start to fall under a high mitigation scenario. The result is a delay more than 10 years longer than earlier estimates. doi.org/10.1029/2025... #climatechange #EEI #warming #emissions #pipeline
The Elephant in the Room - Why the average UK citizen is dragging around a five-tonne energy ghost. Today is the UK’s Overshoot Day. It is the day we officially "break the bank" of the UK’s share of the Earth's natural resource budget for the year. #sustainability #overshoot #ecology #resources
Coal burning is lowering the efficiency of solar power through air pollution blocking sunlight. This is not trivial either. In 2023 it caused a 5.8% reduction, equivalent to 111 TWh—the amount generated by 18 medium-sized coal-fired power plants. #solar #energytransition #coal #power #pollution
After a short period of mass gain in 2022, related to anomalous snowfall in East Antarctica, Antarctica’s mass balance is negative again. Ice losses are steadily increasing, with the ice sheet losing 56 Gt of ice in 2023 and 82 Gt of ice in 2024. Waiting for 2026 data.

New AI Approach Reveals Ocean Currents in Unprecedented Detail. The new technique uses deep learning to recognise subtle patterns in ocean surface temperature caused by currents that conventional analysis can’t resolve. #oceans #currents #oceanography #models
The Ember Global Electricity Review 2026 was published yesterday with some great news on renewable growth and declining fossil fuel use. Key takeaways 🧵👇 Report: ember-energy.org/app/uploads/... #energy #electricity #renewables #cleanenergy #fossilfuels #energytransition
Ash clouds settling on the oceans driving increased productivity through the supply of nutrients and carbon dioxide sequestration are a key player in the late Miocene Cooling phase.

The EEI shows the energy the plant is absorbing by comparing the energy coming in from the sun, and the energy leaving through reflection and infrared radiation. As such it is a direct indicator of the heat accumulating, global warming and climate change.

A new paper has uncovered a universal temperature curve that governs all life. They looked at temperature tolerance curves for thousands of species from microbes to reptiles confirming them all to have a "universal thermal performance curve.” #climatechange #temperature #massextinction #biology
Today, March 14th, the US has used its share of renewable resources for the year. The rest of the year's resource use is being stollen from the following years and generations. #overshoot #resources #USA
The traditional model of a steady, linear climb in global temperatures is increasingly at odds with observations. We've relied on the ocean’s ability to act as a storage buffer for thermal energy. Recent data on Ocean Stratification indicates this buffer is undergoing a mechanical decoupling.
Look at the graph image again, now image the mirrors stretching widthwise 48 kilometres to the right and left.
As climate change accelerates "fire weather," we are witnessing a global shift toward successional traps—dehydrated landscapes locked in a cycle of frequent, high-intensity burning. #climatechange #wildfire #firemanagement #hydrology #watermanagement #mesophication #bioticpump #deforestation
Carbon dioxide overload, detected in human blood, suggests a potentially toxic atmosphere within 50 years according to a new peer reviewed study of 7,000 human subjects over 20 years. link.springer.com/article/10.1... #emissions #humanhealth #publichealth #pollution #blood #chemistry #biology
The CERES satellite project provides observations of Earth’s energy flows and cloud properties and the data for 2025 is now available. It shows continued acceleration of climate warming, reductions on albedo and cloud coverage and can tell us a lot about where the Earth is heading. #climatechange
Europe’s “untouched” wilderness was shaped by Neanderthals and hunter-gatherers even back during the last interglacial 125,000 years ago. A new study links ecology, archaeology and palynology (pollen) to decode hominid influence on Europe long before agriculture. journals.plos.org/plosone/arti...
It’s no surprise that the Mediterranean Sea has experienced significant warming recently, but a new biological study finds it is changing into a tropical sea from the base of the food chain upwards. #climatechange #oceans #Mediterranean #foodweb #plankton #oceanhealth
🤞 The 'temporary' rescinding of the Endangerment Finding will be as effective against the tide of global market penetration of EVs as deregulating the lead content of horseshoes would have been in 2010.
Great Frankly Nate, very thought provoking. You are absolutely right about the wide boundary constrains and the blinkers that the industry don't seem to be able to look beyond. Some AI art you might like - I call it "The day after AGI"
Fertilisation of the ocean with mineral dust promotes algal blooms that capture carbon, but when the same thing happens in Greenland, it reduces albedo leading to accelerating melting. A new study analysed dust collected from the Greenland Ice sheet and found minerals essential to algal growth.

Ancient pine trees growing in eastern Spain have quietly recorded more than five centuries of Mediterranean weather. Analysis of tree rings clearly shows that todays storms and droughts are becoming more intense and more frequent than almost anything the region has experienced since the early 1500s.
