Fellow reviewers 📣: Anonymity is a tool for honesty, not a license for cruelty. Opening a review with "This is poorly written" is unhelpful and unprofessional. Give specific, actionable critique. We’re here to improve the research and build the field up, not tear people down.

If this is accurate, it would seem that @saic-edu.bsky.social is less concerned about critical thinking and education of students and more re-education of staff. ‘We call it the P-word’: Chicago professor suspended after assignment mentions Palestinians www.theguardian.com/us-news/2026...

In their Letter to the Editor published in the Irish Times @irishtimes.com, the scientists set the record straight by rebutting multiple errors in John FitzGerald's opinion piece last week: "Framing the debate as a false dichotomy...distracts from the real choices" www.irishtimes.com/opinion/lett...

Screenshot of the first half of a letter published in the Irish Times – Letters to the Editor, October 26th, 2025. Text reads: "Climate change and farming Sir, – In his recent article “Cutting the entire cattle herd to reduce emissions makes no economic sense,” Prof John FitzGerald usefully acknowledges the scale of change required in the Agriculture, Forestry and Other Land Use (AFOLU) sector. However, his article misrepresents our recent study, National temperature neutrality, agricultural methane and climate policy: reinforcing inequality in the global food system. First, FitzGerald writes that “some of these scientists also argue that Ireland should essentially end all livestock production”, and implies that this is advocated in our study. That is incorrect. Our study does not call for ending livestock farming. Nor does it make any recommendations about its future structure or scale. Second, FitzGerald suggests our work advocates a per-capita methane quota. It does not. We presented per-capita methane as a diagnostic to illustrate disparities in methane emissions across countries. The study does not propose a quota or trading scheme. Our study highlights the risks and uncertainties created for Irish society by the Climate Change Advisory Council’s (CCAC) proposed “temperature neutrality” approach to carbon budgets, which defines climate ambition around a moving target that depends on uncertain future global emissions. It also exposes the underlying value judgments embedded in this framing, which undermine climate ambition, global fairness, food security and land use policy. Arguments that hide the scale of the climate challenge behind a flawed national “temperature neutrality” target, and the false premise that Ireland’s agricultural sector is economically optimised and feeding the world, have become increasingly common. However, they avoid the clear-headed, strategic decisions needed to set Irish farmers up for success in a rapidly changing world. 2 Text: "From a global food security perspective, Ireland exports around 90 per cent of its animal-sourced food products, yet less than 1 per cent of those exports reach low-income, food-insecure countries. Domestically, fewer than half of Irish farms are economically viable, despite the sector receiving billions in public subsidies. Post-2030, Irish taxpayers will be paying billions of euro to purchase carbon credits from overseas to compensate for missing EU climate targets. Continuation of business-as-usual sells both Irish farmers & society short by failing to invest in our land’s potential to deliver healthy & sustainable food, bio-based materials, energy, carbon removals & ecosystem services. Our study does not present an extreme position. Instead, it calls for ambitious, Paris Agreement-aligned land use policy with clear targets, enabling Irish society to steer the AFOLU sector toward a sustainable transition pathway. The potential for a positive, resilient, & diversified AFOLU sector is clearly shown in scenario modelling contained in the yet-to-be-released Land Use Review Phase 2 report completed in May this year. The question is not whether farming will dramatically change over the coming decades, but how that change can be managed to deliver the most robust, sustainable, & secure outcomes for Irish society. Framing the debate as a false dichotomy between a flawed climate target and an “end to livestock farming” distracts from the real choices involved in shaping a more sustainable, resilient, & vibrant AFOLU sector. The climate, Ireland’s farmers, & society as a whole, are best served by ambition, scientific rigour & robust debate on real choices, not by shifting goalposts, or the mischaracterisation of legitimate research & researchers as extreme or anti-farming. – Yours, etc, Dr COLM DUFFY University of Galway, Dr RÓISÍN MORIARTY University College Cork, Prof HANNAH DALY, University College Cork DAVID STYLES associate professor, University of Galway

John FitzGerald's @irishtimes.com article today grossly misrepresents scientists, science & economics –No, scientists do not say "eliminate all cattle from our fields" [our?] –Sci critiqued CCAC "climate neutrality" test –CCAC's key scenarios also show deep methane cuts – 🇮🇪 dairy is NOT "efficient"
