Scientists are naturally conservative with predictions. It's unfortunately the case that climate change is generally happening much faster than those conservative predictions. All the more reason for urgency from governments.

Global renewable energy generation surpasses coal for first time Record solar expansion and steady wind growth driving world’s shift away from fossil fuels in 2025, report finds The world’s wind and solar farms have generated more electricity than coal plants for the first time this year, marking a turning point for the global power system, according to research. A report by the climate thinktank Ember found that in the first six months of 2025, renewable energy outpaced the world’s growing appetite for electricity, leading to a small decline in coal and gas use.

Wastewater treatment plants are a major source of pharmaceutical pollution, study finds Municipal wastewater treatment plants are ineffective at removing Prozac (fluoxetine) and other common pharmaceuticals in wastewater, causing the drugs to be discharged into lakes, rivers and streams where they pose a risk to aquatic organisms.

Conventional municipal wastewater treatment plants are unable to effectively remove many pharmaceuticals, resulting in the release of active drug compounds into rivers and streams. doi.org/g94rq5

This is the playbook, folks.

If you're not paying attention now and doing something about it, then you're going to have to sit down the rest of your life because democracy is being taken away.

Many companies are using this tech already, the improvements made in the last couple of years have been unprecedented. As AI is now contributing to its own development, I don't see this momentum slowing. Combine with things like vertical farming and regen agriculture we can make positive changes.

I need to make clear that I'm not an expert. We have people in the partnership that are better qualified to answer this question. However, I think advances in AI and computer vision could help spot early signs of food going off, cut waste, and make supply chains more transparent and efficient.

NEW RECORD: The UK just recorded its hottest summer on record, per the @metoffice.gov.uk

Four heatwaves, persistently warm nights, and widespread water shortfalls pushed the season into unprecedented territory.

Human-driven climate change made this summer about 70x more likely.

Leaving the ECHR won’t β€œTake Back Control” – it will hand your rights to politicians The myths are seductive, the reality is very different – without the ECHR your freedoms rest on whichever Home Secretary wakes up grumpy

🧡 Farage is whipping up anger against the ECHR with false claims (see thread).

As The Bear brilliantly writes: β€œThe ECHR [is] the foundation that protects you from your own government.”

That's why leaving the ECHR would be a Really Bad Idea.

There’s a persistent myth that new solar farms don’t really help tackle climate change because panels are β€œmade with coal” and β€œnever pay back” their carbon debt.

This is simply false.

- UN: solar ~8x cleaner than gas, ~19x than coal per kWh
- panels repay CO2 in 4 months; save 57x over life
