New campaign urges public to reduce water use as UK emerges from heatwave
Exclusive: £75m publicity drive will ask people to treat water as precious resource and cut daily use by 28 litres

I'm sure household savings make can a difference. But telling consumers to take shorter showers on the hottest day of the year in the UK (38.1°C) in an environment where large sums have been paid to investors for years and new AI infrastructure projects are being approved in London feels outrageous.

But Thames Water is a private company that has crumbled under decades of underinvestment, cost-cutting and 78 billion paid to shareholders since privatisation. Infrastructure leaks account for 19% of water demand. Also, there are 28 planned data centres that will likely rely on Thames Water supply.

Saw a "Let's Save Water" ad in the cinema last night. In the ad, children learn that we could be short 5 billion litres of water a day in 2050 and develop outrage over their parents' wasteful water use. The ad is part of a 75mn publicity drive by regulators and water companies.

New investigation finds conflict coltan from DRC mines controlled by M23 is likely ending up in everyday tech. Five of Rwanda’s seven biggest coltan exporters bought smuggled conflict minerals. Industry due diligence systems largely failed to stop it. gwitness.org/4fBWlpM

Number of UK newspaper editorials arguing for more (blue) and less (red) climate action, 2011-2025. Some editorials also present a “balanced” view, which is categorised as advocating for neither “more” nor “less” climate action. These editorials are not represented in this chart.

This is the Raspberry Pi setup. It's attached to a microphone on the outside that records bird sounds (and only that!). The sounds are classified using BirdNet (birdnet.cornell.edu), a popular bird classification machine learning model.

I used the Google Earth Engine Python API to obtain images from NASA's Landsat 9 mission and mapped shortwave infrared light as red, near-infrared light as green and green light as blue. If you are interested in the code or have feedback, let me know. (Note: this is a personal project).

I used a combination of spectral bands that highlight burned areas and changes in soil moisture. The red spots in the 2025 image are areas affected by the recent wildfires. The cyan-colored spots in the 2024 image are peaks covered by snow in the Tehachapi mountains.

Remote sensors pick up light that is not visible to the human eye. If we map them to visible channels, we see things we would otherwise not see. These two images from NASA's satellite program Landsat show Los Angeles and its surrounding area in January 2024 and in January 2025.
