How one country’s potential climate backslide could block others from feeding themselves, and… The Dangerous Allure of ‘No Additional Warming’.

What if wealthy nations could lock in high methane emissions and still claim climate neutrality?

That’s the risk with “temperature neutrality”.

Here’s the plain-English version of our new study:

If “no additional warming” replaces net zero, is that progress — or backsliding?

Ireland is our case study in a new paper 🔗 doi.org/10.1088/1748...

We found it:
(1)Grandfathers high emissions from wealthy livestock nations, (2)Shifts burden,
(3) Fails on food security

Over 80% of badgers culled in government TB programme found to be free from the disease More than 8,000 badgers destroyed by DAFM in a nation-wide crackdown to eradicate bovine tuberculosis were found to be infection free following post-mortems.

I've always been puzzled as to why there is so little public outrage over the mass-slaughter of badgers in Ireland - a gentle animal that pays a heavy price for the failings of the livestock industry

Trump freezes $2bn in Harvard funds after it rejects demands The White House sent a sweeping list of requirements to the university last week, which it said were aimed at fighting antisemitism.

Harvard sets an example for other US universities by standing up for intellectual freedom and the right to protest - both key to responsible science.

One fuels innovation and critical thinking; the other ensures accountability and alignment with public values.

Is Chatgpt being a little more sycophantic latley?

Its constant applause of my questions is starting to make me feel like I am chairing a Trump cabinet meeting.

For every Irish person that saying "I don't like Conor McGregor... But"

Let me remind you, as recently as 2008 thousands went abroad looking for work, we were damn glad of our social welfare system then too, we were all on it!

Xenophobia and racism are bloody light sleepers!

What the world needs now is more fossil fuels, says Trump’s energy secretary Chris Wright signals abandonment of Biden’s ‘irrational, quasi-religious’ climate policies at industry conference

You couldn't make it up ...

"The Trump administration will treat climate change for what it is, a global physical phenomenon that is a side-effect of building the modern world,” he added. “Everything in life involves trade-off.”

It is getting pretty nauseating watching certain US political leaders running around insisting the whole world "thank them" every time they're challenged on something.

Pretty damn needy if you ask me.

<1% of animal sourced food products make it to low-income countries, yet, the argument often is, we should be producing more nutrient dense animal sourced foods till everyone has access ....

No amount of doing the wrong thing will ever make it right—just more wrong.

Ukraine ‘gambling with world war three’, Trump tells Zelenskyy in fiery meeting Talks between US president and Ukrainian leader degenerate into shouting match before being cut short

This is not a man that deserves any respect at all, and neither does his shitheel vice president.

It's time for the world to move on from the US.

There is no leadership to be found there.

It acknowledges the need for redistribution and food system transformation.

It frees up the shrinking emissions pie so others can build resilience.

It recognizes that our current system of excess is unhealthy, unjust, and unsustainable.

Reducing emissions-intensive consumption in the Global North doesn’t redistribute food—but it does something just as critical:

This misses the point entirely. The problem isn’t just about food distribution—it’s about who gets to use the planet’s limited resources.

High-income countriesexceed their fair share of planetary capacity, while lower-income countries are unable develop sustainable food systems.

The arrogance in the #DublinDeclaration astounds:

"Taking goods away from high-income populations does not make them more available to low-income populations. A steak that is not eaten in the Global North does not turn into eggs that are therefore more available to stunted children in Africa."

I thought this was a good response, not that it is on the front pages.
