This paper argues that the threats to humanity and the biosphere from environmental damage is much greater than is usually acknowledged, and that current political and economic solutions do not match the scale of the danger. The authors call for scientists to speak “candidly and accurately” to policymakers, businesses and the public about the risks to our future.

This book by FCRN member Paul Behrens uses paired chapters of pessimism and hope to show how much needs to be done to achieve a hopeful future, but how this would involve actively building a healthier and more fulfilling world. The book covers subjects including food, energy, climate and economics.

In this report, UK food waste NGO Feedback critically assesses the narrative that anaerobic digestion (AD) is a viable solution for producing renewable gas from organic matter such as crops and wastes. The report argues that preventing food waste in the first place is more effective than generating biogas from waste food, particularly if trees were to be planted on the land spared.

This paper addresses recent concerns about RCP8.5, a climate scenario developed by the Intergovernmental Panel on Climate Change based on an assumption of high levels of fossil fuel use. A recent commentary argues that RCP8.5 was originally intended to explore an unlikely future with no climate mitigation, but that it is now commonly referred to as a “business as usual” scenario by the media. In response, this paper argues that RCP8.5 is indeed a good match for current and stated climate policies up until 2050.

This progress report from the UK’s Committee on Climate Change assesses progress in reducing UK greenhouse gas emissions over the past year and makes recommendations on how to ensure the post-COVID-19 recovery is green and resilient. It includes discussions of agriculture, diets and land-use change.

The Global Alliance for the Future of Food held the Salzburg Process on the Climate Emergency and the Future of Food in May 2020. In this blog post, Ruth Richardson (Executive Director of the Global Alliance) reflects on lessons learned from holding the event virtually because of COVID-19, rather than physically as originally planned.

This blog post John Lynch of Oxford’s Livestock, Environment and People programme asks whether we can keep farming cows and sheep without dangerously warming the planet. He points out that it is possible to maintain stable temperatures without eliminating methane emissions entirely (in contrast to CO2 where emissions have to fall to net zero to tackle climate change). However, ruminant methane emissions are currently increasing. Furthermore, ruminants use a lot of land, some of which could be used for other purposes that might sequester more carbon.

The average number of days that US farm workers spend working in dangerously hot conditions could double by mid-century and triple by the end of the century, according to this paper. Workplace adaptations such as longer rest breaks, working more slowly, switching to single-layer clothing and having cooled rest areas could tackle this problem, but would negatively affect farm productivity, worker earnings and labour costs.

This paper uses temperature and precipitation projections across the ranges of over 30,000 species on land and in water to estimate when each species will be exposed to dangerous climate conditions. It predicts that most species within a given assemblage (group of species within a habitat) will encounter inhospitable climate conditions at the same time as each other (e.g. several species might have a similar upper limit on the temperature that they are able to cope with), meaning that disruption of the overall assemblage is likely to be abrupt.
