Hands up if you know what Global Goal 4 is!

Who wants some good news? The overwintering monarch population, which had plummeted last winter, has doubled this winter! www.worldwildlife.org/stories/east...

Up and up it goes! For the first time in human history, CO2 has averaged over 430 ppm. Off the charts. We are locking in suffering. Time to change habits. Fast.

Exciting news for Scotland!

On Friday, a whole mountain west of Glengarriff was burnt, with a wall of flames visible through the night for miles around. It's pure ecocide, layered on top of ecocide (sheep), and it just beggars belief that this is still going on in the year 2025.

🇺🇸 The USA is no longer a serious nation. It’s not April yet. 🇬🇱 www.congress.gov/bill/119th-c...

Progress in the 21st century is under threat. The sustainable development goals are now, surely, a pipe dream. How inhuman the wealthiest countries are. And how shortsighted.

Let’s find this footage — I think I have it on VHS (!!) but it has to be ‘out there’. Black and white film. First footage from space. Can’t find it. Pint for anyone who identifies it.

Physics teachers - help please! I think the original 1999 BBC ‘The Planets’ has a clip of one of the first rockets (with a camera) going into space. But I can’t find it. Anyone remember the episode please? Or have another source?

Frost on solar thermal panels — good for teaching absorption and reflection of radiation! Location: Cambridge

From “British Petroleum” to “Beyond Petroleum” to “Burn Planet”

Reality check. Thank you, Financial Times.

For over a decade, I’ve spoken to whole year groups at school, often on my own, about Sustainability issues, for PSHE. Tomorrow, I see year 11. Here’s a sneak peak of the first two slides. These are getting VERY hard to do.

As the brilliant @petraboynton.bsky.social has pointed out, this piece makes no mention of FRS Elon Musk who is directly responsible for much of the threat science is currently under.

UK's net zero sector growing at 3x rate of rest of the economy, growing 10% in 2024, wages £5,600 higher than the national average "The Conservative and Reform parties did not respond to requests for comment" 😂😂😂 Because it shows their position is bollocks www.theguardian.com/environment/...

☄️ 🔭 The impact probability of asteroid 2024 YR4 has dropped from 2.8% to 0.16%. Thanks to new observations, Earth is now at the edge of our shrinking ‘uncertainty window.’ If this trend continues, the risk may soon reach 0%.

Science Hole.

Burning food in transport is mad. Electrification makes far more sense physically and arithmetically.

The Many Lives of James Lovelock is the next BBC Radio 4 Book of the Week! Tune in to the first episode read by Richard Goulding on Monday at 11.45 and learn how the pioneer ecologist came to have “two loves: the natural world and bombs.” www.bbc.co.uk/programmes/m...

Good grief. That’s not a mistaken gesture.

It matters that scientists speak out against what is being done to US science. Staying silent is neither "objective" nor "staying out of politics". Silence now *is* political - it supports the status quo, says "nothing to worry about". We need to sound the alarm. www.nature.com/articles/d41...

I was lucky enough to meet Sir John Houghton at Cambridge University Press. Here 25 years ago, he and @georgemonbiot.bsky.social discuss Climate Change as understood in January 2000. Remarkable listen. Ask yourself: what’s changed in our approach today? www.bbc.co.uk/sounds/play/...

From the ECIU: Slow transition to EVs could cost UK car industry thousands of jobs The UK's car industry could support 167,000 more jobs by 2035 in a speedy transition compared to a loss of 404,000 in a slow, worst case scenario eciu.net/analysis/rep...

measles is one of the most infectious diseases out there and it is a dangerous illness, particularly for young children - vaccination has kept it at bay for decades. Not vaccinating - and not suppporting vaccination - has consequences

The suffering this change inflicts! Education is the most important issue in the world.

Anyone teaching gears soon might like to get pupils to inspect this image!

very cool to be living through the Twitter takeover except for weapons of mass destruction fortune.com/2022/11/06/t...

Makes you wonder where all the future engineering applicants are going to get their A Levels in Physics and Maths from…

One of the most shocking graphs I've made. Using NASA CERES data, IPCC forcings and very low-, mid- and very high- climate feedbacks multiplied by the NASA GISS temperature trend. If the NASA satellite data is right, the IPCC forcings and feedbacks are likely all wrong More soon

A fine point.

Science being under attack means our knowledge and understanding of the way the world works is under attack. Nobody gains from this.

‘I do not want a fellowship that can include such actions.’ Elon Musk's fellowship is undermining the purpose of the Royal Society, writes resigning fellow @andrewmillar.bsky.social. In this piece, he tells us why he feels enough is enough. www.researchprofessionalnews.com/rr-news-uk-v...
