Higher CO2 levels have been increasing tree size in the Amazon, potentially increasing carbon uptake but this may be short lived as larger trees can be more susceptible to climate change intensified heat & drought: www.nature.com/articles/s41...

The latest report from the Planetary Boundaries Science Lab at PIK has confirmed that Ocean Acidification has now been breached. This means that 7 of the 9 planetary boundaries have now been crossed. #planetaryboundaries #PIK #oceans #oceanacidification #climatechange

Despite what you may have heard, global warming is very real and demonstrated by looking at real satellite observations over the last quarter of a century. drtomharris.substack.com/p/a-deeper-d... #climatechange #globalwarming #CERES #EEI #albedo #greenhousegases #aerosols #clouds

Antarctic Sea Ice loss could be a tipping point after all. A new paper investigating the likely return of sea ice following CO2 removal shows that under some circumstances, the sea ice does not return. agupubs.onlinelibrary.wiley.com/doi/10.1029/... #antarctica #seaice #tippingpoint #stratification

NEW: Methane emissions could lock in 0.3°C of extra warming – pushing societies towards collapse. Our new report outlines proven, low-cost solutions across energy, agriculture, and waste that could cut emissions by 45% – protecting health, food and livelihoods.

The Caspian Sea is shrinking at record speed – water levels falling up to 30cm a year. Simon Goodman (Univ. of Leeds) warns this is a glimpse of climate risks we all face. These changes are here, now. We need forward-looking plans to adapt, and to act without delay.

A new field study has revealed unexpectedly high soil carbon emissions in wet tropical forests. The increased soil respiration increased CO2 emissions by between 42 and 204% depending on the terrain. www.nature.com/articles/s41... #climatechange #emissions #tropics #forests #feedback

Climate models tend to go out to 2100 allowing most scenarios and reports to tell us that temperatures will be X, sea level rise will be Y, but I, along with most of you, will be dead by then. drtomharris.substack.com/p/2050-is-le... #climatechange #globalwarming #economy #tippingpoint

SETI offers up a lesson on sustainability. New research concludes that the closest technological species to us could be 33,000 light years away but their civilisation would have to be at least 280,000 years old to coincide with us. meetingorganizer.copernicus.org/EPSC-DPS2025...

Two new studies in Antarctica provide new melting drivers not properly included in climate models or sea level rise predictions. One on the vast East Antarctic interior and one on the massive ice shelves. #Antarctica #sealevelrise #climatemodels #iceshelf #icesheet substack.com/profile/3195...

The amount of carbon that forests can take up is much lower than previous estimates. If we don't reduce CO₂ emissions rapidly, we can say goodbye to the Paris climate targets forever.

Safe underground CO2 storage could only reduce warming by 0.4-0.7ºC according to a new study assessing the prudent limits of CCS. When taking a risk based approach, the industry estimates are reduced by an order of magnitude. substack.com/profile/3195...

With the NASA CERES data now available to the end of June, its a good time to see how the energy flows are progressing, driving climate change. drtomharris.substack.com/p/earths-ene... #climatechange #acceleration #albedo

Given that the fossil fuel industry is using the same playbook as the tobacco lobby, this is an interesting article in itself, but also relevant to fossil fuel emissions. theconversation.com/cigarette-fi...

Most-viewed Guardian articles last night. Editors shouldn’t think that the public doesn’t want to know more about climate change. Or about ocean science 🌊! Read the article about our paper: www.theguardian.com/environment/...

The Guardian on our study published today: www.theguardian.com/environment/...

I was shocked when I first saw these results from standard climate models used in IPCC reports: for high emissions, the Atlantic overturning circulation #AMOC shuts down in all 9 models that ran past 2100, and is well on the way to shutdown by 2100. Our paper on that is out today.🧵

In our latest blog, CCAG member Professor @mazzucatom.bsky.social explains why global climate commitments need to go hand-in-hand with national economic strategy, and how they can become powerful levers for inclusive, innovation-led growth. Find out more here: www.ccag.earth/news/nationa...

Antarctica is experiencing abrupt changes, suggesting regime shifts in a number of critical systems. A recent review paper lays out the evidence and the likely implications for these changes. drtomharris.substack.com/p/antarctica... #Antarctica #climatechange #sealevelrise #icesheet #penguins

Whenever a story appears about increasing risk of wildfires, some helpful chap always likes to comment “that global burned area is declining so stop being alarmist.” A new paper explains the paradox. www.science.org/doi/10.1126/... #climatechange #wildfire #fireweather

Heat isn’t just a physical health risk, it also gets us down emotionally. A study analysed 1.2 billion social media posts linked to geographic, weather and economic levels to measure the mood under different temperatures. Paper: www.cell.com/one-earth/ab... #climatechange #heat #mentalhealth

Ozone will warm the planet more that expected according to a new international study led by the University of Reading. By 2050 the increased ozone warming will be equivalent to 15% of the additional CO2 warming. acp.copernicus.org/articles/25/... #climatechange #ozone #EEI #clouds #albedo

This SINGLE WEEK of Spanish wildfire emissions surpassed ANNUAL total carbon emissions of each of the 100 lowest emitting countries in the world‼️ Carbon sinks are turning into sources We can’t expect nature to clean up our mess.

A recent paper examined the 200 year story of greenhouse gas emissions and based on projected GDP growth suggested the world could pass +3ºC by 2050. Is that even possible? drtomharris.substack.com/p/3c-by-2050... #climatechange #emissions #GDP#economicgrowth #paris #carbonintensity #carbonbudget

This is an excellent article and well worth the long read. Grab a coffee first 👇

Hurricane Erin passed north of the Caribbean over the weekend with a rarely observed show of strength. It’s only the 43rd Atlantic based Cat 5 on record and ties for the 4th earliest. It also had the 4th highest recorded strengthening rate, gaining 85mph in 24 hours. #hurricane #climatechange

Truly devastating for Trump's climate report. It just shows once again: if you task a group of "climate skeptics" with a climate report, you get a mass of easily refuted falsehoods, as they simply do not have honest arguments on their side. interactive.carbonbrief.org/doe-factchec...

Marine heatwaves are an increasingly common component of climate change. Their intensity and regularity are increasing as warming accelerates, the oceans adapt and we reduce pollution. drtomharris.substack.com/p/worse-thin... #climatechange #oceans #marineheatwaves #fisheries #coralreefs #SST

Analysis of coral skeletons have shown that sea level rise started accelerating in the late 1950s, earlier than previously thought. The study extends the precise record of Indian Ocean sea level back to 1900. www.nature.com/articles/s41... #climatechange #sealevelrise #coralreefs #oceans #maldives

Overshoot scenarios are the only way to meet the Paris goals. They involve massive carbon dioxide removal which will be hard and expensive. Are they required though? Won’t net-zero do the job of keeping us safe? drtomharris.substack.com/p/overshoot-... #climatechange #paleoclimate #overshoot

That's just one of many instances of distortion and misinformation in the US Department of Energy "Critical Review on the Impacts of Greenhouse Gas Emissions". Which in fact is a fossil fuel propaganda scam. Let's hope Americans are not that easily fooled. tamino.wordpress.com/2025/08/03/s...

A global study has identified an upswing in land based photosynthesis since 2003, but a decline in the oceans. Net Primary Productivity through photosynthesis captures CO2 and is the foundation of all food webs. Overall the result is an increase but the numbers are small.

Wow, that is quite a clever deception to downplay sea-level rise in the DOE climate report. You have to read the vertical axis label in their graph and understand what “trailing trend” means. StatisticianTamino explains it nicely in his blog. tamino.wordpress.com/2025/08/03/s...

Ocean oxygen decline threatens deep-sea fish population, ocean health and carbon sequestration according to Mediterranean fossil evidence from the last 10,000 years including the last anoxic event. www.nature.com/articles/s43... #climatechange #oceans #oxygenation #anoxic #Mediterranean
