To achieve the #UN Sustainable Development Goals (#SDGs) in 193 countries, we need stronger civil society participation in their implementation & monitoring.

The disastrous loss of the Gulf Stream - which would give U.K. the climate of Labrador and blight the whole world - is not inevitable. New research shows that the tipping point could be averted if emissions come down.

Good news. Bluefin tuna numbers are recovering after coming close to total collapse 20 years ago. Catch restrictions have had a dramatic effect - a lesson for other fisheries.

🌴Thanks to satellite data, we know how much forest the world is losing, and where.

Unless we know what’s driving tree cover loss, it’s impossible to know if it’s permanent or temporary; what the impacts are for people, nature and climate; and the solutions to keep forests standing. That’s where new data comes in.

Data on @globalforests, developed in collaboration with @GoogleDeepMind, reveals that 34% of tree cover losses worldwide from 2001-2025 were likely the result of permanent land use change, meaning trees won’t grow back naturally. This percentage nearly doubles in tropical primary rainforests, to 60%.

The world today is characterized by large-scale inequalities. And a climate crisis is looming over us.

We urgently need a new vision for global progress in the 21st Century. One that grounds human development and equality in planetary habitability.

What would it take to achieve high prosperity and equality while remaining within planetary boundaries?

The World Inequality Lab is very excited to launch the #GlobalJusticeReport.

Back in the 1990s some expected that climate action would ramp up as the scale of the disaster became evident. As it happens, the opposite is the case. Ever more catastrophic impacts are accompanied by diminished ambition & political attacks on decarbonisation. Hard to explain.

[Alex Veremeyenko @alex_verem]

Let me trace the timeline here because nobody's connecting it.

Step 1: Scrape the entire internet. Every book, every article, every conversation, every piece of art, every forum post. Do it without asking. Do it without paying.

Step 2: Train a model on all of it. Call it "artificial intelligence."

Step 3: Go to BlackRock's Infrastructure Summit and announce: "We see a future where intelligence is a utility, like electricity or water, and people buy it from us on a meter."

Step 3 is where you sell people's own knowledge back to them. On a meter.

They took the collective output of human thought, compressed it into a model, and now they want to charge you by the token to access a version of what you and everyone you know already created.

One Reddit user put it perfectly: "They stole all this data from us, the people, our life's work, creativity, art, by devouring the internet and blowing through all copyright laws. Now they want to sell it back to us in the form of a utility."

Imagine if someone photocopied every book in the public library, burned the library down, and then opened a subscription service for the copies.

That's the metered intelligence business model.

And they're pitching it to infrastructure investors as though they invented water.

The pace of climate change has doubled, just as political and business commitment to tackling it has crashed. Our children, grandchildren, and their descendants living in a much more hostile climate - will see this as history’s greatest betrayal.

Wind energy cut the wholesale price of electricity by 31% from where it would have been without them last year, following a 25% reduction in 2024. Ministers urgently need to ensure this is passed on to consumers.

[Prof. Katharine Hayhoe @KHayhoe]

This article says climate change is “believed to have played a role” in the UK's extreme heat this week.

As a climate scientist, let me fact-check that.

First, climate change is not a religion. No belief is required. It is about evidence.

And the evidence has been crystal clear for more than two decades: climate change is making heat waves hotter, longer, more frequent and more dangerous.

In fact, science has advanced far beyond saying climate change merely “played a role.” Today, we can quantify how much more likely and how much hotter climate change made a specific event.

Here's the bottom line:

Climate is changing. Humans are responsible. And we are experiencing the impacts now. That’s the bad news.

The good news is that solutions already exist, and the majority of people care - 89%, around the world!

But meaningful action depends on helping people understand not just what is happening: we need to know how it affects our lives (this heat wave being example A today) and what we can do about it.

That’s the opportunity this reporting missed.

⚡Electrification will dominate the new phase of global #energytransition. The share of #electricity in global final energy consumption would rise from around 23% today to 35% in 2035, & above 50% in 2050—making electricity the dominant energy carrier in the global energy system.

NEW | Wind and solar just produced more electricity than gas globally for the first month on record

In April, they produced 531 TWh (22%), compared with 477 TWh (20%) for gas.

Wind and solar generation has more than doubled in the last five years.

Norway and the UK drilled the same North Sea.

🇳🇴Norway got $2 trillion.
🇬🇧The UK got tax cuts.

Same basin,Same era.... Completely different outcomes.

Norway captured $30 per barrel in government revenue. The UK captured $11.

That gap, compounded over 50 years of production, is the entire difference.

Norway's model was simple: tax heavily (78% marginal rate), take direct equity stakes in fields via the SDFI, own part of Equinor, and put everything surplus into a fund invested abroad.

The Government Pension Fund Global now holds over $2 trillion in assets.
That's $390,000 per Norwegian citizen about 1.5% of all listed equities on earth.

The fiscal rule: only spend the 3% annual real return. Never touch the principal.

The UK started producing earlier, at lower prices, with a lower tax rate (40%) and no saving mechanism.

North Sea revenues flowed straight into the general budget.

Economists estimate the UK missed out on roughly £400 billion compared to a Norwegian style regime.

The windfall largely financed tax cuts in the 1980s rather than a fund.

Where things stand in 2026?

Norway's petroleum sector will generate $63 bn in net cash flow this year alone feeding a fund already large enough to cover 10-15% of the national budget from returns alone.

The UK is a net energy importer.
Since 2021 it has paid countries like Norway more than £100 billion for gas.

One country treated oil as a finite resource to convert into permanent financial wealth.

The other treated it as income.

Head of International Energy Agency: Fossil fuel era won't recover after global oil shock:

-Countries increasingly turning to electrification and renewables

-Long-held assumptions about the reliability of fossil fuels shattered

-Confidence underpinning global oil and gas markets weakened

-Fragility of fossil markets exposed

-Expanding fossil projects will not help

NEW ANALYSIS: What's going on in Spain?

Spain's wholesale electricity price in early 2026: €44/MWh. Italy: €127. Germany: €96. UK: €103.

Wind+solar deliver 44% of generation. Gas sets price in just 9% of hours, down from 55% in 2022.

Battery storage can now enable wind and solar to produce continuous power at an economic price, reports an international agency. The old intermittency objection to renewables is losing its validity.

Spiralling global temperatures (1850-2026)

It is exactly 10 years since I first put this animated graphic of changes in global temperature online. #ClimateSpiral

It instantly went viral.

People watched it over and over again.

It still offers the power to shock a decade on.

As I said on @bbcquestiontime - Farage’s £5m bung from some crypto tycoon in Thailand absolutely stinks. And Yusuf’s evasion here makes it stink even more. If Starmer or Badenoch had been caught doing this without declaring it, Farage & Yusuf would demand they resign.
