Your local librarian here to say that it’s great if you read lots of books this year, alright if you read barely anything, that audiobooks, romance and graphic novels are all valid formats and genres, and that some authors suck but we’re still not stopping you from reading them.

From 2004–2011, ~62,000 African Penguin died near Cape Town because of sardine collapse caused by climate change and overfishing. That’s ~95% of the breeding penguins! In 2024, African Penguins were uplisted to Critically Endangered on the IUCN Red List.

The thickness of #Arctic sea ice dropped to a new all-time record low this year around the North Pole (data from PIOMAS). More in my latest 'climate viz of the month' blog: zacklabe.com/climate-viz-... #OpenScience #SciComm #DataViz #OpenData

The results from Wales and elsewhere show a 25% reduction in casualties. So if you keep a 30mph limit on urban/village roads where pedestrians and cyclists mix with motors you are imposing 1/3 more casualties on your community. It's why Transport Professionals are saying #20splenty

The Met Office global average temperature forecast for 2026 suggests another year above 1.4 °C compared to pre-industrial levels (1850-1900), being the fourth year in succession exceeding 1.4 °C. Prior to this surge, the global temperature has never exceeded 1.3 °C. 🔗 Read more: bit.ly/491qWrE

Recent research reveals that deep-sea mining could dramatically threaten 30 species of sharks, rays, and ghost sharks whose habitats overlap with proposed mining zones, further endangering species already at risk of extinction. Read more in Science Daily: https://ow.ly/CtSN50XG94U

Among the places with Highest positive temperature anomalies this month we have GREENLAND For example so far this month the average temperature at Narsarsuaq has been +2.9C which is a whopping +8.4C above the 1991/2020 norm and it's even 1C warmer than its OCTOBER average:Crazy

The latest UK Hydrological Summary has been published 🌧️ November was UK's wettest month so far in 2025 & many areas have shifted from drought concerns to flood risk. Groundwater levels notably low and reservoir levels still below average in parts. Winter rainfall amount will be crucial. 🧪 1/

Warming oceans are having widespread and often negative effects on migratory seabirds, new research involving UKCEH shows. The study compared seasonal sea surface temperatures with seabird numbers to quantify effects on reproduction, survival & population trends. doi.org/10.1073/pnas... 🧪1/

Glaciers are key for climate, ecosystems & water supply. @nature.com publishes research on their extinction. Some still think that can wait or allow dirty solutions much longer. The good news is that we have already effective & affordable technologies to cut emissions! www.nature.com/articles/s41...

A pocket of very warm air (relative to average) over the North Pole enabled highs to reach above freezing Sunday. Meanwhile temps in the Midwest struggled to get above zero. Upside down day.

In the world we live in today, that is 1.3C warmer due to our continued burning of fossil fuels, the extreme rainfall leading to disastrous flooding in many parts of Asia is up to 50 to 160% more intense - new @wwattribution.bsky.social study www.worldweatherattribution.org/increasing-h...

It was my experience of deforestation in Borneo when I reached my tipping point. I stopped flying, became vegan, became an activist with @scientistsforxr.earth, and left academia to become a filmmaker. Storytelling might have more impact than my work in science. My film: fires-and-fascism.co.uk

TIL about a memorial ceremony in Iceland in 2019 to mark the end of a glacier, changing the place name from Okjökull to Ok (jökull = glacier). Uncompromising wording on the bronze plaque: "This is to acknowledge that we know what is happening and what needs to be done. Only you know if we did it".

How likely is an #AMOC shutdown? Here's our latest study based on 768 runs with 38 standard climate models (the CMIP6 models). Note these do not include any meltwater from Greenland mass loss, so might underestimate the risk a bit. 2/2 iopscience.iop.org/article/10.1...

The UK has become one of the most nature-depleted countries in the world. In this set of discussion papers, funded researchers discuss examples and approaches to deepen our understanding of place-sensitive nature recovery, exploring the links between people and nature.

We’ve had our heat pump for 12 months now estimate that we’re about £280 better off. That surprised me as we moved from oil which is cheap, and I was expecting the heat pump to be marginally more expensive. Just goes to show! Buy a heat pump folks!

5/ These winds from the east are projected to keep weakening around the Antarctic margins as a result of climate change. This means that as the climate changes, more warm water could come onto the shelf and cause more ice to melt, which could raise sea levels around the world. 📸 C. McMillian

Iceland has designated the potential collapse of a major Atlantic Ocean current system a national security concern and an existential threat, enabling its government to strategize for worst-case scenarios, the country’s climate minister told Reuters.

Heat pumps are awesome.

62 wolves have been killed in Montana since hunting season opened. Killing wolves is neither supported by science nor ethics, yet it becomes a reality when wolves lose federal ESA protections. As the numbers climb, how many more wolves will be lost without reason?

Never forget: At breakneck speed we are leaving the stable Holocene climate in which human society developed and thrived. Weather extremes are outside historical experience. Sea-level rise is accelerating. Dangerous tipping points are ahead. Graph: ed-hawkins.github.io/climate-visu...

NEW RESEARCH: Our study shows high-temperature heat pumps are the most cost-effective path to decarbonising industrial heat at low to medium temperatures. We find industrial heat pumps can cut heating costs by up to 75% vs h2 & and beat natural gas. www.cell.com/cell-reports...

Marine CO₂ removal lacks standardized indicators to quantify carbon removed and environmental impacts. This absence of reliable metrics prevents verification, inhibits investment, and blocks entry into carbon trading systems. iopscience.iop.org/article/10.1...

So what is a #Supermoon? Well, the Moon is typically ~¼ million miles away (30 Earths in a row), but thanks to its elliptical orbit, that distance changes. Tonight the Full Moon is 2-Earths closer than normal (221,823 miles away), making it appear ~15% brighter than usual hence #Supermoon! 🔭🧪

Wow. I did not know that Alfred Russell Wallace (co-discoverer of evolution by natural selection) wrote a book in 1904 about the biological potential for life on other planets, and I've just found this extraordinary paragraph setting out the insanity of atmospheric pollution [1/3]. In 1904!
