"Greens must discover how to generate real resonance: speaking to people’s lived experience, hopes, fears and longings in ways that travel further and land more deeply, without hollowing out what we stand for."

Today is World Ocean Day and our oceans are being bombarded by all kinds of threats like pollution, over-fishing, acidification, etc…
But as a meteorologist, I’ll discuss the rapid warming!

We often focus on air temperatures. But the real story is in the oceans.
More than 90% of the excess heat trapped by greenhouse gases is retained in the ocean.

Each year a new assessment is released, and in 2025 the world’s oceans gained an astounding 23 zettajoules (ZJ) of heat.

In relatable terms that’s equivalent to:

🌊 37 years of humanity’s current annual energy consumption

🌊 About 380 million Hiroshima-sized atomic bombs worth of energy

🌊 More than 200 times the world’s annual electricity generation

And that’s just one year!

Why does this matter?

Warmer oceans can fuel marine heatwaves, coral bleaching and death, sea level rise through thermal expansion, contribute to bigger land heatwaves, and provide more energy for heavy rainfall and tropical cyclones. Ocean warming also stresses marine ecosystems that support fisheries, biodiversity, and coastal economies around the world.

The ocean has shielded us from much greater atmospheric warming by absorbing the vast majority of Earth’s excess heat. But that protection comes with growing consequences for ocean health.

On this World Ocean Day, it’s worth remembering that the ocean is not just responding to climate change, it’s bearing the brunt! We must protect our oceans.

Batteries cut gas ~70% during Australia's April evening peak since 2025!

I shared a post about ALDI's renewable energy program and someone asked about Coles and Woolworths.

I looked it up. By the end of 2025, Australia's three largest supermarket chains were all sourcing 100% renewable electricity across their operations.

This honestly surprised me.

ALDI was the early mover, achieving 100% renewable electricity across its Australian operations in 2021.

By the end of 2025, Coles and Woolworths had caught up.

That means Australia's #1, #2 and #3 supermarket chains have all independently arrived at the same conclusion.

ALDI alone has installed 122,000+ solar panels across 300+ stores and 6 distribution centres. Coles and Woolworths have pursued similar strategies, combining rooftop solar with long-term renewable energy agreements.

Together, we're talking about roughly 2,400+ supermarkets, distribution centres and logistics facilities.

What struck me is that most shoppers have no idea.

I certainly didn't realise my local ALDI roof was covered in solar panels until I checked Google Maps.

Which suggests this isn't being driven by marketing or virtue signalling. If it were, you'd expect to hear about it constantly.

Instead, the panels quietly sit on rooftops while customers walk underneath them every day.

The more likely explanation is simpler. The numbers worked.

When an entire industry independently converges on the same solution, it's usually a sign that economics is doing the heavy lifting.

The energy transition isn't just happening at solar farms and wind farms.

It's happening on our local supermarket roofs.

What is it that makes some people enjoy killing animals?

The excuse is often - oh it's traditional, we've always done it

You could have said the same things about slavery

F*ck tradition - no excuse for such cruelty in 2026

Nearly 100 fans from Morocco applied to go the USA.

The US blocked nearly 90% of their applications.

This is the most racist World Cup ever and it should be boycotted by everyone, the USA is refusing to let non-white people come.

How to read this graph-

The red = the months of the year we're mining our biophysical foundations to support the scale of the human enterprise.

We've been mining our foundations since 1973.
A some point, our foundations collapse.
Scary thing? No one knows exactly when 🔥

Three minutes of essential viewing from Years and Years by Russell T Davies.

Vivienne Rook, a populist figure who emulates Farage, normalising the use of “camps” to deal with a *British* population stricken by unrest and social collapse.

This is the Reform/ Restore blueprint.

The ability to grow and store grains at scale is what makes civilisation possible, we can't have one without the other.
In my article titled "On the Verge of Starvation" the first paragraph reads: "“By 2027 the world could be facing a 214 trillion calorie deficit, says Sara Menker, founder and chief executive of Gro Intelligence, an agricultural data technology company.”
That analysis predates DJT's war on Iran and the global food supply.

--What made the modern food system seem resilient was never abundance alone. It was geography. Regions like the North American Prairies, Ukrainian Steppe and northern India grow much of the crops that feed humans and livestock.

The system works because crop failures are expected to be local, not simultaneous. If one breadbasket region fails to produce one year, another could cover the shortfall. The Earth itself provides a kind of buffer, but that buffer is thinning.

Multiple breadbasket failures are becoming more likely as climate change increases the chance of simultaneous stress across major producing regions. The danger is no longer only a bad harvest in one place. It is the possibility that several of the regions the world depends on for staple crops could come under pressure at once.-- via Kevin Hester
