As the EPA prepares to axe the Endangerment Finding, essentially wiping out emissions control, Big Oil is not as pleased as you might expect. HEATED explains why 👇 substack.com/inbox/post/1... #climateaction #EPA #endangermentfinding

New study looks at extreme Greenland melting events over 1950–2023: - Seven of the ten most extreme events occurred after 2000. - Future projections under high-emission scenarios suggest that extreme meltwater anomalies could increase by up to +372% by 2100. 🌊 www.nature.com/articles/s41...

How do we predict the climate of 2030, 2050 or 2100? We have to interrogate the past. Modern weather records only go back about 150 years. To understand where our planet is heading, we need a longer memory. drtomharris.substack.com/p/the-isotop... #ClimateScience #Paleoclimate #climatechange

Predicting tipping points in complex noisy signals is hard, but essential as so many are approached. Annual and natural cycles make it even more challenging, but a new approach looks very promising. www.nature.com/articles/s41... #climatechange #tippingpoints #AMOC #Amazon #glaciers #CSD

Devastating floods have hit Portugal, Spain & Morocco in the past days, causing loss of life & billions of Euros in damages. How does climate change impact the flood risks from rain, rivers & rising seas? Watch my lecture Flooded Futures: What are We Planning For? 🌊 www.youtube.com/watch?v=wtd8...

Scientists outline the case for next-generation Ocean Iron Fertilisation (OIF) field trials in a new publication. OIF is a marine carbon dioxide removal strategy which enhances natural plankton blooms allowing them to capture and sequester CO2. journals.sagepub.com/doi/epub/10....

The presumed upcoming El Nino will help cement and quantify global warming acceleration, showing that 2C global warming is likely to be reached in the 2030s, not at midcentury.

The Methane spike in the early 2020’s has been explained in two new studies. A combination of weakened atmospheric removal and increased emissions from warming wetlands, rivers, lakes, and agricultural land are to blame. www.science.org/doi/10.1126/...  www.science.org/doi/10.1126/... #methane

Today, a new report from University of Exeter and Carbon Tracker shows how the economic models used by governments, central banks and investors are increasingly understating risks as we head toward 2°C. Read the full report here: greenfuturessolutions.com/news/recalib...

Two new studies show positive signs of how warming is increasing the destruction of the number 2 and number 3 Green House Gases. Forest soils are absorbing more methane and nitrous oxide break down in the stratosphere is accelerating. #Greenhousegases #climatechange

Just out today: The report “A Nordic Perspective on AMOC Tipping” reviews the current state of science on the risk of Atlantic Meridional Overturning Circulation (#AMOC) shutdown. 🌊 Conclusion: it's "a serious risk which requires a dedicated risk management framework". pub.norden.org/temanord2026...

As the world turns its eyes toward the Winter Olympics, a more sobering reality is unfolding across the global mountain cryosphere. Our mountains are not just playgrounds; they are the world’s most critical, and most fragile, life-support systems. drtomharris.substack.com/p/going-down...

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.

Interesting article in Nature on the implications and future science and policy implications of "overshoot". 👇 www.nature.com/articles/d41... #climatechange #Parisagreement #overshoot

Whilst US attacks on Greenland's sovereignty are creating dangerous geopolitical instability, the island's ice is rewriting the rules of global climate. New evidence shows it is no longer just a victim of warming, but an active participant in it. drtomharris.substack.com/p/the-unstab... #Greenland

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.

More evidence of AMOC weakening was published this week, in a study looking at water renewal and ventilation in the North Atlantic. Paper: www.nature.com/articles/s41... #amoc #atlantic #oceans #climatechange

⛷️ ⛸️ The 2026 Winter Olympics in Milan and Cortina d'Ampezzo, Italy starts soon on February 6! 🔥 And it's a heck of a lot warmer—+6.4°F—than the first time Cortina held the Winter Games back in 1956. 📊 Let's ski jump right in ⬇️

While newsroom focus is on Davos and Greenland, the UK Government has quietly published its National Security Assessment on Global biodiversity loss, ecosystem collapse and national security. This was ‘delayed’ since October, but sneaked out while no-one was watching this week.

The latest report from the Institute of Actuaries has just been published. The report highlights climate sensitivity and geoengineering following a warning that “catastrophic warming levels of above 2°C by 2050 are likely.” #climatechange #risk #actuaries #finance #economy #planetaryboundaries

The World Economic Forum 2026 risk report makes depressing reading but only looks 10 years ahead, I wonder why not 25 years? #WEF #Davos #globalrisks #collapse

I take some comfort in knowing that in a 3°C world that fascist governments, corrupt politicians, evil billionaires, lying media and dehumanizing corporations will no longer exist. I just wish that were the case in a 1.5°C world. Patience.

Uninteresting piece on the ‘Last Ice Area’ in the Arctic, the Queen Elizabeth Islands where the oldest ice can still be found. Warming has allowed the first ship based survey and science mission into the area. Story: www.science.org/content/arti... #climatechange #arctic #seaice

The race is on to save records of Alpine glacier ice before they melt away. An archive is being created in Antarctica for ice cores taken from around the world. The cores store invaluable scientific information that would be lost to future study. phys.org/news/2026-01... #climatechange #glaciers

Is plastic pollution a hidden driver of global warming? 🌡️ Most ESG strategies treat "Waste" and "Carbon" as separate pillars. My latest article shows that this siloed thinking is a mistake. drtomharris.substack.com/p/choking-th... #ClimateChange #Microplastics #albedo #photosynthesis

Amazing views of Jupiter last night as the Earth was at its closest to the gas giant. The bands and line of moons were clearly visible through powerful binoculars. Over the next few weeks, take a look at it, you can't miss it in East in the evenings. Enjoy!

You may have seen this new graph a few times now, but here’s why its so important. Its a measure of the amount of heat accumulating in the ocean waters, not just the surface temperature. #climatechange #oceans #oceanheatcontent #OHC #globalwarming #floods #storms #coral

Your 'moment of doom' for Jan. 3, 2026 ~ Transitioning to doom. "More hydrogen means less OH [hydroxyl radicals] in the atmosphere, which means methane persists longer and thus warms the climate for a longer period" blackout-news.de/en/news/hydr...

I want to wish all my followers on Bluesky, and my subscribers on Climate Uncovered over on Substack, the very best for the Holiday Season and for the New Year. I look forward to bringing you more science paper reviews and articles in 2026. Thank you for your support.

A new study has examined 5.7 million years of mid latitude rainfall to examine the pattern of hydro climate extremes. 300m lacustrine sediments cores were drilled and analysed for the work. www.nature.com/articles/s41... #climatechange #jetstream #hydroclimate #drought #flood #arcticamplification

Jump in SSTs 2023-24 from dual tropical Pacific warming centres & eastward-extended North Atlantic jet stream, boosted by a large global energy imbalance driven by rising grenhouse gases & falling aerosol that was exacerbated by preceding extended La Niña heat sequestration: doi.org/10.1038/s432...

Spotted this rare Red Rainbow this morning just after dawn. Just lovely 🌈 Apparently it's caused by most of the green, blue and yellow light from the low sun being scattered by the atmosphere, leaving mostly red light for the rainbow.
