Coastal Connections: How “Temperature Neutrality” Could Worsen

What’s This All About?

Irish scientists just published research that’s got people talking. They looked at a new way Ireland might handle climate targets called “temperature neutrality” – and they’re not impressed.

The basic idea sounds reasonable: instead of cutting our farm emissions dramatically, we’d promise not to make them any worse. But when researchers ran the numbers, they found this approach could seriously harm poorer countries.

The Simple Version of What They Found

Imagine if everyone in a village was trying to clean up a polluted river. Some people (like Ireland) have been dumping a lot of waste in it for years. Others barely dump anything.

“Temperature neutrality” is like the big polluters saying: “We’ll stop adding more waste, but we won’t clean up what we’ve already dumped or reduce what we’re currently dumping.”

Meanwhile, the people who barely pollute get told they can’t increase their dumping at all – even if they need to for basic survival.

What the Numbers Actually Show

The research team ran different scenarios through climate models to see what would happen. They found that under “temperature neutrality,” Ireland would still be producing methane at six times the global average per person by 2050.

That’s like if everyone in the world was supposed to eat one slice of cake, but Ireland was still eating six slices while telling everyone else they can’t have more.

Why This Matters Beyond Ireland

Here’s where it gets really unfair: Most of Ireland’s beef and dairy exports go to other wealthy countries that already have plenty of food. But this policy would make it much harder for poor, food-insecure countries to develop their own livestock farming – exactly where better nutrition is desperately needed.

Dr. Colm Duffy from University of Galway who led the study, puts it bluntly: “I had more, so I get more.” Countries that historically produced more emissions get to keep producing more, while countries that didn’t pollute much get restricted.

What Our Local Scientists Are Saying

Professor Hannah Daly from University College Cork points out that methane is responsible for about 40% of global warming so far. Because methane doesn’t last long in the atmosphere, cutting it quickly is one of our best tools for slowing climate change.

Dr. Róisín Moriarty, also from UCC, says this approach is basically Ireland backing down from our Paris Agreement promises when we should be doing more, not less.

The Coastal Connection

You might wonder what this has to do with our coastal communities. Well, quite a bit:

Climate Justice: We’re seeing sea levels rise and coastal erosion first-hand. We know climate change hits some people harder than others – this research shows how policy choices can make that inequality worse.

Economic Missed Opportunities: The research suggests this approach would delay new green markets that could benefit Irish farmers and coastal areas. Instead of leading innovation, we’d be protecting old ways of doing things.

Our Reputation: Ireland exports a lot through our coastal ports. If the world sees us as climate laggards who protect our own interests at others’ expense, that affects our trade relationships.

But What About Seaweed?

Many of you have asked: “Why not just feed seaweed to cows to cut methane? Wouldn’t that create jobs here and solve the problem?”

You’re onto something. Seaweed additives could potentially cut cow methane by up to 80% while creating a whole new coastal industry. The problem some still questions are near ready to do this at the scale needed.

Think of it this way: promising to use seaweed feeds to meet climate targets right now would be like promising your dinner guests a fancy meal based on vegetables you haven’t planted yet and you needed licenses to do so.

The scientists aren’t against seaweed research – they’re against making climate promises based on technologies that aren’t ready yet.

The Bigger Picture

When the researchers tested different approaches, “temperature neutrality” performed almost as badly as doing nothing at all for global warming. Only “business as usual” was worse.

If every country adopted this approach, we’d basically give up on limiting warming to 1.5°C – the target scientists say we need to avoid the worst climate impacts.

What This Really Means

This isn’t just academic research – it’s about real policy choices Ireland is considering. The Climate Change Advisory Council has proposed this approach to the government, partly to make our 2050 climate targets easier to hit.

But the research shows there’s a hidden cost: maintaining global inequality while undermining international climate efforts.

Why Should We Care?

As Nua Mara, we understand that our actions affect others and that others’ actions affect us. This research shows how climate policy can either promote fairness or entrench unfairness on a global scale.

The question isn’t whether change will be challenging – it’s whether we’ll face that challenge honestly or try to take shortcuts that hurt others.

The scientists involved – from University of Galway, UCC, University of Melbourne, and Climate Resource – are essentially saying: “If Ireland wants to be a climate leader, this isn’t the way to do it.”

The Bottom Line

“Temperature neutrality” might sound reasonable, but the science shows it’s really about protecting wealthy countries’ privileges while limiting opportunities for those who need them most.

As communities that understand both environmental challenges and global connections, we have a stake in getting this right – not just for the climate, but for basic fairness.
