It enrages me that companies-BP seek short term profit over the future, it could so much better for people (more money and more comfortable homes) For anyone that's interested I was interviewed by Toby Foster on BBC Radio Sheffield (26/02/25) 4.10 - 4.30pm www.bbc.co.uk/programmes/p...

Starmer's apologists will tell us "it's too soon to criticise him" until 2028, whereupon they'll tell us, "it's too close to the election, now is not the time." There is never a wrong time to hold your government to account.

Since 1979, Arctic ice declined by more than 2 million square kilometers The pale color of ice reflects more than 80% of light that hits it back into space But when ice melts, light instead hits the darker seawater below it, which reflects only about 10% of sunlight climate.mit.edu/ask-mit/how-...

The UK has fully privatised Energy, France fully nationalised.

Post 302 (incl. posts on X) The global sea-ice area still VERY low. Antarctic lost only 48,000sq. km and holding at joint 3rd. Arctic up 149,000 km and kept at the worst in the record. Antarctic at 2,019,000sq. km and 787,000km below average. Arctic at 13,943,000km and 1.5million km below average.

👏🏼👏🏼👏🏼

Post 301 (incl. posts on X) The global sea-ice area lowest ever recorded. Antarctic lost 292,000sq. km and holding at 3rd. Arctic up 284,000sq. km and kept at the worst in the record. Antarctic at 2,891,000sq. km and 824,000km below average. Arctic at 13,794,000km and 1.6million km below average.

QUOTE OF THE DAY…

Reform UK’s Richard Tice says it’s ‘absolute garbage’ to say human activities are the main cause of climate change Heaven help us

Donald Trump sees his trade war as a show of strength. In fact, it’s the opposite | Larry Elliott

Post 300 (including X) Scared now for both cryospheres bad things happening? Antarctic lost 672,000km & dropped to 3rd (10th last wk). Arctic GAINED 55,000 & kept at the worst in the record. Antarctic at 2,359,000km & 836,000 below average. Arctic at 2,359,000km & 1.7million km below average.

It's utter madness. In today's column I discuss how Labour in the UK, just like Trump in the US, is dismantling the administrative state. And how this makes its other plans, including the good things it's trying to do, impossible to implement. www.theguardian.com/commentisfre...

In 2004, it took the world a year to add a gigawatt of solar power — now it takes a day

Bird flu is now spreading from birds to pets to people, but Donald doesn't want you to know that because it might make him look bad.

AOC, one of my heroes! You go girl!

Wow! The number of @bsky.app users just passed 31 MILLION!👏 LETS DO THIS!

Received a letter from POTUS today purporting to remove me as Commissioner and Chair of the FEC. There's a legal way to replace FEC commissioners-this isn't it. I've been so fortunate to serve the American people and stir up some good trouble along the way. That's not changing anytime soon.

I've been encountering over the past few days the claim that the planet is warming twice as fast as predicted. This is entirely untruthful and unhelpful. The planet is warming AS fast as predicted, which is cause enough for dramatic action. The truth is bad enough!

480 million years old: Octopuses have sex chromosomes more ancient than dinosaurs Now Spain wants to factory farm and breed over a million Octopuses stuffed in tanks in constant light and then freeze them to death interestingengineering.com/science/olde...

Scientists estimate that one extra death is caused for every 4,434 tonnes of CO₂ emitted. The top 12 billionaires combined emit almost 17 million tonnes a year—causing around 3,800 extra deaths a year, or an average of 320 deaths each. No wonder they're in denial...! References👇

I think this should be worthy of intense media coverage as January 2024 records a temp 1.7oC institutions.newscientist.com/article/241623… In addition, the Arctic has LOST 148,000sq km of floating ice over the last 5 days (Spring ice lost usually begins an about a month). Stay aware this is serious

Post 299 (incl posts on X). Worrying data for both cryospheres; Antarctic lost 687,000km and dropped to 10th (16th last wk). Arctic LOST 67,000 and dropped to the worst in the record. Antarctic at 3,031,000km and 538,000 below average. LESS ice in Arctic 13,455,000km & 1.5 million km below average.

I have many regrets about Earth, but making humans in a wide range of colors, shapes, and temperaments is not one of them. Celebrate thy diversity. Love each other.

In the 20th century, they were known as "concentration camps." Now, they are simply called "housing." Doesn't that sound so much more humane? Voila, problem solved!

Post 298 (including X posts) Antarctic holding compared to last week. losing 558,000km this week and dropped 16th (15th last wk). Arctic gained 309,000km but dropped to 2nd worst in the record, Antarctic at 3,718,000km and 243,000 below average. Arctic at 13,522,000km & 1.2 million km below average.

Spiteful, orange little man.

Any journalist who thinks that coral bleaching on the GBR was “first seen in 2024” hasn’t been paying attention. Mass mortality of corals due to climate change was 1st recorded in 1998, following by 2002, 2016, 2017, 2020, 2022 & 2024. See www.cell.com/current-biol...

This is #climate change and proof that Earth is warming not cooling A strong Jet stream that normally keeps cold air locked in Arctic increasingly weakened due to Arctic melting, allowing cold air to seep further south as far as Florida and warm air to flow to Alaska

If she can do it, we can all do it.

This is the face of courage and compassion. Thank you Bishop Mariann Edgar Budde for speaking truth to power on behalf of the marginalized.

At the National Prayer Service, Bishop Mariann Edgar Budde delivered a heroic, spontaneous act of rebellion—a sermon calling for mercy for immigrants and LGBTQ+ people. Naturally, Donold and his cult are big mad. Let’s break it down.

Doesn’t get more conclusive than this.

Post 297 (incl. posts on X). Still a wide split but Antarctic rapidly worsening, it lost 1,018,000km this week and dropped 15th (25th last wk). Arctic only gained 225,000km and stayed at 3rd, Antarctic at 4,276,000km and 235,000 below average. Arctic at 13,213,000km and 1.3 million km below average.

The more urgent the need to address climate change, the more intense the fossil fuel forces darkness push back against action. Shame on them. #ClimateCrisis #LosAngelesFires #ClimateAction
