Merry Christmas 🎄

There's only 600 m2 of forest per person in the UK. That's less than a 25 x 25 m block. Stats from Chris Quine at #BES2025

As we move into the final days of the year, 2025 has just overtaken 2022 as warmest year-to-date for Central England.

Given the forecast, it looks likely that 2025 will end up being the warmest calendar year for this region since records began in 1659.

The top 3 warmest will be 2022, 2023 & 2025.

A three-column infographic showing that simple arrows are ambiguous because people interpret them in many different ways. The left column displays nine identical right-pointing arrows. The middle column lists possible interpretations: “First this, then that,” “Zooming in,” “Zooming out,” “This is the range,” “This element’s name is,” “The trajectory,” “All of this,” “Things come together,” and “Things split apart.” The right column offers visual alternatives for each meaning: numbered steps for sequence, magnification insets for zooming, a 0–100% bar for range, a label pointing to an element for naming, a dotted path for trajectory, a bracket for grouping “all of this,” a merging fork for things coming together, and a branching fork for things splitting apart.

Arrows are tricky. For us, as the designer of the visual, it will be super clear what it means. But for someone looking at our visual for the first time, it can be highly ambiguous. Depending on the reader, the same arrow can mean sequence, zoom, range, label, movement,...

As a researcher who straddles multiple domains, I present to you my remote sensing and ecology advent! I'll be sharing a short blog on how ecologists can use remote sensing data to ask cool questions 😎🎄

I'm on day 2, ndvi & friends.

5-month Keeby update 💙

Just launched Lazy Cats, a visual exploration of cat behaviour. Meet Lily + 27 other cats and find out what they do all day (spoiler: they mostly chill) 🐱🐾 Does your cat fit their profile?

Very proud to share my first interactive #dataviz project built with Svelte + D3! 📊

Huge team effort led by the brilliant Fabian Fischer!

3 months with Kiba 🥰

Some highlights from my week at the Interdisciplinary Summer School on Forests:
🌳 Playing with all kinds of cool data - dendrometer time series, TLS point clouds, satellite data (optical & SAR)… 🛰️
🌳 Building AR tree models & playing AR games in the forest 👾
🌳 The people! #ConnectedByTrees 💚

Congratulations Kate! 🎉

Ember's Global Electricity Review 2025 YouTube video by hankschannel

When you spend months collecting data and writing a report, you always worry it won’t actually be read by many people…

@hankgreen.bsky.social’s latest video brings our Global Electricity Review 2025 to many more (and different) people than we’d typically reach.

Check it out!

Canopy functional trait variation across Earth’s tropical forests - Nature Data from a variety of sources—including satellite, climate and soil data, as well as field-collected information on plant traits—are pooled and analysed to map the functional diversity of tropical fo...

Tropical forests are not all the same: they show many shades of geographical variation. Our new paper in Nature led by @jeaggu.bsky.social combines field and satellite data to make a first map the canopy functional traits of the world’s tropical forests: www.nature.com/articles/s41...

I'm #hiring: PDRA to join my #ukriflf project to understand how forest structure, function and dynamics are linked in Europe, using high resolution remote sensing data (TLS, UAV-LS). Based in Cambridge.

Please share! 🌳⚡🛰️🌲

Forest Productivity Decreases in Response to Recent Changes in Vegetation Structure and Climate in the Latitudinal Extremes of the European Continent Aim Climate change is driving increasingly frequent and intense extreme climatic events, pushing many forests worldwide beyond their physiological thresholds. Despite the major role played by forest...

Our newest paper led by Julián Tijerín-Triviño finds that #climatechange is slowing the productivity of European #forests: onlinelibrary.wiley.com/doi/10.1111/geb.70011

We used 3 surveys over 15-30 years from >13,900 NFI plots in Mediterranean, temperate and boreal regions (1/5)
