Glow-worm in Oxfordshire. Found in the UK after a hot dry day Jun-July 10PM-midnight. It's a challenge to photo only using the light from the beetle itself. #photography #insect #macro en.wikipedia.org/wiki/Lampyri...

I had a very rare clear night, but I was too ill to go outside in the cold. I had to see what I could get out of the window. #photography #urbanlandscape #astrophotography

Rainfall in the UK is increasing. That’s a fact. Graph below from the Met office. As the planet heats, more moisture is absorbed into the atmosphere which means rainfall increases. 2024 was the hottest year ever recorded.

Melting 12 billion tons, 12,000,000,000,000 kg of ice in a single day requires 4 EJ (exajoule = 10¹⁸ joule) of heat.
That's 63,500 Hiroshima bombs worth of energy, at 63 TJ (terajoule = 10¹² joule) each.
Humanity’s global energy use is about 1.64 EJ per day.

Our rivers are polluted, bills are rising, and private companies are failing. It's time the Government acted and brought water back into public hands.

NEW: For over a year, the Israeli government has deliberately denied Palestinians in Gaza the minimum water needed for survival, most likely resulting in thousands of deaths.
