Climateflation: the food system in crisis

Jonathon Porritt 11th Dec 2025

Someday soon, our mainstream media is going to blow the gaff on today’s self-appointed tribunes of the people who, often in the very same speech, will inveigh against the ever-rising cost of living (and the scourge of food inflation in particular) while robustly asserting that climate change is a myth—a middle-class obsession that imposes outrageous costs on working families.

I can’t say I much like the word, but the portmanteau ‘climateflation’ should provide a bit of a heads-up for these loathsome hypocrites. Food prices have been rising for all sorts of different reasons, and it’s not easy to attribute a particular percentage of these rises to the impact of climate change on food crops and supply chains. But figures of anywhere between 10% and 20% have been cited, with specific reference to extreme heat reducing crop yields around the world (all crops have their own heat tolerance limit), as well as the growing frequency of floods and droughts.

Major food retailers in both Europe and the US are much more exercised about the way this is translating into price rises for fruit and veg in particular, although the language they use often steers clear of pinning it explicitly on climate change. How about this for a classic euphemism from the British Retail Consortium: “seasonal food inflation driven by weather”!

……………………………………………. climateflation is already with us, with an average temperature increase of around 1.5°C since the Industrial Revolution. No surprise then that projections for future impacts (with average temperature increases of 2°C+) are getting truly scary. The European Central Bank looked at potential impacts by 2035, causing food prices in Europe to rise by between 1% and 3% every year, adding 0.3% to 1.2% to whatever the rate of inflation might be in any one year.

The reprehensible get-out for politicians is that even the most sophisticated climate models are still not much cop when it comes to projecting extreme weather events, let alone the movement of pathogens (pests and diseases) as the weather goes on getting warmer. It’s always after the event that the true scale of the damage becomes clear—as with the killer bacteria ‘xylella fastidiosa’ that has been ravaging Italy’s olives over the last decade, resulting in significant hikes in the price of olive oil. The prices of both chocolate and coffee have been similarly affected by different climate-induced factors.

All that’s bad enough, but we should be thanking our lucky stars we don’t live in one of the many countries directly affected by retreating glaciers. A report from UNESCO in March this year (the World Water Development Report) confirmed that the food and water supplies of around 2 billion people will be affected over the next two or three decades by what is now the fastest rate of glacier melting on record. We’re not just talking about food inflation here—we’re talking about life and death for hundreds of millions of people…………………………………………………………………….

The cruellest response to all this that we hear from the politicians is that farmers must ‘adapt.’ But there’s really not a lot the individual farmer can do as once-reliable weather patterns go berserk, as warmer temperatures steadily reduce moisture in the soil, and as demand for irrigation water steadily rises—even as food retailers remain as greedy and inflexible as ever.

So is that it then? Just factor in the inevitability of worsening climate inflation and invest in more food banks for those already struggling with the cost of food? Absolutely not! In fact, there are four big things the UK government needs to be focusing on right now:

Get really serious about food security. (Professor Tim Lang’s report earlier this year (“Just In Case”) written for the National Preparedness Commission, provides the clearest possible warning of the vulnerability of the UK’s food system to external shocks).
Regulate the hell out of all those companies profiting so handsomely from the sale of ultra-processed food.
Encourage consumers to eat less meat.
Reduce food waste — both at the farm gate (particularly in poorer countries) and post-consumer.

Uncomfortably, that means acknowledging that Big Ag (that drives or benefits from each of these meta-impacts on our health and the environment) poses as great a threat to the well-being of people and to our prospects as a species as Big Oil. Which is why you won’t find many politicians venturing into this increasingly controversial territory. https://jonathonporritt.com/climateflation-food-system-crisis/
