Trying to refreeze Arctic sea ice by pumping ocean water onto its surface is infeasible and a distraction from emissions cuts, but it signals how desperate we are because we’re simply not decarbonizing fast enough (or at all).

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 www.nature.com/articles/s41...

🌡️ Today, I'm happy to launch the "Reuters Climate Monitor," a live data dashboard that aims to track the slow-moving impact of climate change at the speed of the news. You can find it at https://www.reuters.com/graphics/CLIMATE-AUTOMATED/MONITOR/akpeykqqapr/

Antarctica’s west coast missing an area of sea ice the size of France as temperatures peak 20C above average. A vast area of the Bellingshausen Sea should be covered by sea ice by now, with one expert calling the loss of ice ‘depressing’ It’s more than depressing - it’s a disaster.

A U.S. District Court has issued an order stopping the administration from censoring American history and science and ordering the restoration of unlawfully censored information displayed in national parks, including signs explaining the impacts of climate change.

NEW: The UK's 7th carbon budget will be subject to a vote of the full House of Commons, following a half-day debate. Previous budgets were voted through after brief debate in a sub-committee. Background on the budget here: www.carbonbrief.org/...

Via Altadena climate expert Edgar MacGregor: "Winter is now hotter than spring used to be."

🚨 Carbon dioxide averaged 432.34 ppm in May 2026. This marks a new record high for the month of May and the annual seasonal peak. 10 years ago May averaged about 408 ppm. This continued rise is driven by human emissions from fossil fuels, with climate change impacts intensifying around the world.

Now that Poland's vehicle sales data have been published, we have enough to cover 78% of the EU market. Current estimate is that the total EU saw 21% BEV and 12% PHEV in May.

Our new paper on the challenges of marine CO₂ removal has a pretty figure. Please admire it. 🌊🧪

Breaking News! Code UFB!!! Sea-surface temperature records are being shattered daily, and yet this El Nino is just getting started ...

On June 4, 2026, the SST was highest on record for the time of year in the Niño3.4 region, an area in the Pacific indicative for development of El Niño. The inset shows sea surface temperature anomalies on June 4, 2026, with the Niño3.4 region highlighted. arctic-news.blogspot.com/2026/05/ocea...

The 12-month running average temperature for the Contiguous U.S. continues to be at a record high.

Spring (Mar-May) temperature time series for the Contiguous U.S. It's as if something has changed. 🤔

18000 tonnes of CO₂ removal over 10 years is a time machine that takes you back ~1 second every year. TD Bank Group would do a lot more for climate if it stopped investing in fossil fuels.

🔥 Europe had their warmest spring (Mar-May) on record.

2025, more power was generated worldwide from renewables than from coal, 91% of new renewables are cheaper than fossil fuels. Renewables made 85.6% of last year’s new global power capacity additions. Each year nuclear adds only as much net global power capacity as renewables add every two days.

June 1, 2026, forecast for SST anomalies in the Niño3 region, with forecasts exceeding 4°C for part of some forecast members and exceeding 3.5°C for part of the forecast for the Coupled Forecast System version 2 (CFS.v2) ensemble mean (black dashed line). arctic-news.blogspot.com/2026/05/ocea...

I feel like the photographer could have gotten a little closer tbh

2025, wind and solar became the bedrock of European energy self-reliance. Norway has said no to nuclear and NATO backs renewables as the solution to energy security. Each year nuclear adds only as much net global power capacity as renewables add every two days. The direction of travel is clear.

Arctic sea ice volume was at a record low for the time of year on May 24, 2026, as it has been for years. arctic-news.blogspot.com/2026/05/ocea...

🌊 The ocean absorbs >90% of Earth’s excess heat, and our ability to track it depends on a fragile global network of floats, ships and sensors. New research warns that cuts to the Global Ocean Observing System could make climate signals indistinguishable from noise. www.nature.com/articles/s41...

Lol. Humans will never colonize Mars. Never! "SpaceX gave Musk a package worth 1 billion Class B shares, which vest if the company establishes 'a permanent human colony on Mars with at least one million inhabitants' and hits a series of market-cap goals that expand the company to $7.5 trillion."

152 years(ish) of average annual temperatures in Ottawa, Canada. About 2°C of warming on average.

Add hurricane seasons to the growing list of phenomena (tornado seasons, extreme rains) that climate change is tending to “clump” into more extreme intervals punctuated by quieter periods. Weather and climate weirding, if you will.

Seabirds are running out of ocean. Unlike many marine animals, seabirds don’t reduce body mass to survive climate change, they’re forced to disperse farther as their habitats disappear. By 2100, over 70% of species could lose huge parts of their range. www.nature.com/articles/s41...

Snowplants (Sarcodes sanguinea) are sneaky neat plants, they don't use chlorophyll to get energy, instead they steal sugar from a specific fungus (Basidiomycete Rhizopogon ellenae) which in turn has a symbiotic relationship with pines and firs. They live in the montane zones of western N. America.

Probably costs $120 fill up the RAV 4 today but the EV is still $11

98° in PHL today is an all-time May record and a once in a century event, in our historical climate. Now-a-days we’d expect a day like this much more often. See the chart in the thread… 🧵 #philadephia #philly #record #heat 1/

Two humpback whales have made record-breaking crossings between Australia and Brazil. Scientists say the whales were identified by their distinctive tail markings and traveled about 9,000 miles.

Back in 2012 we did a figure comparing historical emissions to previous generations of emission scenarios. rdcu.be/brDGx Surprisingly, the figure is still doing the rounds. We update it every year, with many interesting changes primarily due to revisions in land-use change emissions. 1/

Keep in mind that climate impacts for the average citizen of a low-income country at 1.5°C of global warming will not be felt by ~40% of people living in high-income countries until global warming exceeds 3°C.

Color me shocked

This is not what you want to see for snow water equivalent values in mid May. There are many basins across the western U.S. literally showing no snow.

Short answer: not really Better answer: fly less

I believe I once directly told some high up that net zero is not some abstract slogan, it is a scientifically derived and legislated target.

TLDR: this agreement does not maintain a path to net zero by 2050

Credit where it's due: this is the article where @volts.wtf gave the world the slogan "Electrify Everything." Pretty sure it predates use of the phrase by Saul Griffith or anyone else. Before that, people wrote about "beneficial electrification." One of the most successful bits of framing I know! 🔌💡

What could go wrong with increasing PM₂.₅ in the atmosphere? 🤷🏻‍♂️

The article misses a key point which is that, now that the identity of these designer particles is public, it's clear they don't make much sense as an SAI material.

Funny how the govt finally draws the line at cars. Everything else we buy in this country is made in China, but they finally get upset about cars being made in China.
