Sentinel-2 and wildfires: These last few days, a devastating wildfire has been raging near Los Gallardos in Spain - sadly resulting in multiple deaths and significant destruction. This pic was taken on 10th July by Sentinel-2A, the scale of the fire clearly visible.

🐄 In the Somerset hills you will find rather less bucolic scenes There you will find “An intensive dairy unit, home to at least 1,300 cows which, contrary to the popular image of milk production, do not graze in the fields which surround the farm“ www.thebureauinvestigates.com/stories/2026...

How I mapped Britain’s hidden ‘battery cows’

I’ve been reporting on factory-farmed cattle for over a decade. The government may finally be ready to take action

1) Open this image up 2) Find the small, blue feature in the very middle Congratulations, you've spotted the Perseverance rover on Mars, photographed from orbit! 3) Trace the rover tracks as they wend their way across the surface

A complex landscape of buttes, hills, hummocks, and sand dunes, in tones of gold and teal. In the middle, a small, beetle-blue feature. Around it, faint parallel tracks.

The map shows historic landfill sites closest to rivers & survey data from the UK Big River Watch highlighting water quality in these areas. 19% of surveys within 100m of an historic landfill site rates water quality as 'very murky'. 11% for all surveys in England & Wales Coincidence or correlation?

Sun and shadow across small valleys in the Driftless-like Root River basin of southeast Minnesota, on the summer solstice. View toward the southeast. I like how the sun at certain times brings out or obscures the unchanneled drainageways dissecting the slopes. #rayshader

In this image I've used a relative elevation model to illustrate ground height in relational to the River Stour as it flows into Pegwell Bay, Kent. This #GIS technique brings alive the effects a #river has on its immediate locality, highlighting the meandering flow path as it reaches the sea. #qgis

A double win for children's health: - walking or cycling to school = more exercise - fewer cars on the road = less air pollution Children are often breathing in air at car exhaust pipe height, so they're particularly vulnerable to pollutants like PM2.5: www.theguardian.com/politics/202...

Ministers want 60% of pupils in England ‘actively’ travelling to school by 2035

Exclusive: Transport secretary, Heidi Alexander, says cycling and walking plan focuses on ‘everyday travel needs’

I want to share sad news of the passing of my father David Lovelace last month. He was an amazing dad, an inspiration for me and others around him, and made a huge contribution to landscape history, mapping and nature conservation where I grew up.

After the wildfire near the Snake Pass summit at the beginning of May, our science team returned to the site to check on the sphagnum plugs we planted in the area over the winter. While our plastic monitoring equipment had melted in the heat of the fire, 98% of the sphagnum plugs didn't burn away.

Graphic with green and red sphagnum moss in the background. Text reads: Did you know? Wetter is better. After a wildfire on Snake Pass in May 2026, our science team returned to the site to check on the sphagnum plugs we planted in the area. Incredibly, while our plastic monitoring equipment had melted, 98% of sphagnum plugs didn't burn away.
