New Zealand has introduced a new bill that aims to bring emissions of long-lived greenhouse gases to net zero by 2050. A separate target has been set for methane emissions from agriculture, with planned cuts of 10% by 2030 and 24% to 47% by 2050.

The UK Parliament has endorsed a motion to declare a climate and environment emergency, in response to the 2019 Extinction Rebellion protests and calls from the Labour opposition. The motion, which is not legally binding, follows declarations of a climate emergency by the Welsh Government, Nicola Sturgeon, First Minister of Scotland, and several cities across the UK.

This report from the UK’s Committee on Climate Change sets out how the UK can reach net zero emissions by 2050 using existing technologies. It notes that current policies do not do enough to meet existing climate targets, and calls for “clear, stable and well-designed policies” to be introduced across the economy without delay. If replicated across the world, the plan would give a greater than 50% chance of limiting warming to 1.5°C.

This report from the Japanese Institute for Global Environmental Strategies shows how lifestyles would have to change in industrialised countries and some industrialising countries in order to meet climate change targets.

Climate mitigation policies rarely account for the time lags associated with land-based greenhouse gas mitigation policies such as reforestation, bioenergy with carbon capture and storage (BECCS) or reduction of agricultural emissions, argues this paper, making it unlikely that commitments under the Paris Agreement will be met.

The US Global Change Research Programme has published the second volume of its Fourth National Climate Assessment, which examines the human welfare, societal, and environmental impacts of climate change and variability across many sectors, including agriculture.

The book “Narratives of Hunger in International Law: Feeding the World in Times of Climate Change”, by Anne Saab, explores two different views of hunger in the context of climate change (neoliberal vs. the food sovereignty movement) and how international law affects these narratives.

Government policies are not doing enough to support the transition to a lower-carbon foods sector, according to a report by the Changing Markets Foundation. Specifically, the report argues in favour of policies to shift the food system away from animal agriculture and towards plant-based foods.

The report “Missing pathways to 1.5°C: The role of the land sector in ambitious climate action”, by the Climate Land Ambition and Rights Alliance, assesses greenhouse gas mitigation pathways that use “low-risk” land-based solutions that protect natural ecosystems and respect human rights. The report aims to provide an alternative to the IPCC’s mitigation pathways, many of which rely on mitigation approaches such as bioenergy with carbon capture and storage (BECCS).

The current front-runner for Brazil’s presidency, Jair Bolsonaro, member of the right-wing Social Liberal Party, proposes to abolish Brazil’s ministry of environment, hand control of agricultural policies to politicians who advocate reducing land conservation and expanding agricultural lands, withdraw Brazil from the Paris Agreement on climate change, and open indigenous lands to mining.

The Intergovernmental Panel on Climate Change (IPCC) has released a special report on keeping climate change to 1.5°C. The report says, “Limiting global warming to 1.5°C would require rapid, far-reaching and unprecedented changes in all aspects of society.”

The cost-effectiveness of different methods of cutting agricultural greenhouse gas emissions is often calculated using marginal abatement cost curves (MACCs). FCRN member Dominic Moran of the University of Edinburgh has quantified the uncertainties in calculating MACCs for Scottish agricultural mitigation options, including improving land drainage, improving the timing of nitrogen application, and using controlled release fertilisers. The paper suggests that policymakers may wish to exclude options that have a high uncertainty, as they may not always be as cost-effective as the MACC suggests.

This book, by Leonard Rusinamhodzi, describes the concept of ecosystems services, shows how to identify and quantify ecosystems services in the context of sustainable food systems, and examines the challenges of maintaining ecosystems services in the face of climate change.

The University of East Anglia’s Global Environmental Justice Group is running a five-week online course on “Environmental Justice”, hosted on the Future Learn website. Several food-relevant topics will be covered, including water justice, forest governance, biodiversity conservation, and climate justice.

A carbon tax applied across the whole economy, including agriculture, could put more people at risk of hunger (in terms of dietary energy availability) than climate change itself, according to a recent paper.

Researchers have warned that a cascade of positive feedback loops could push global temperatures into a “Hothouse Earth” state for millennia, even if human greenhouse gas emissions are reduced. Some systems, such as ice sheets, forests and permafrost, could pass a temperature tipping point beyond which they rapidly become net contributors to climate change. If one is set off, the warming produced could trigger the remaining tipping points, like a line of dominoes.

Researchers from the University of Oxford’s Environmental Change Institute (of which the FCRN is part) have created a new tool - the “temperature of equivalence” - to map the impacts of varying degrees of climate change in different areas. They find that people living in low-income countries will, on average, experience heat extremes at 1.5°C of (global average) warming that people living high-income countries will not encounter until 3°C. This result is based on combining a map of predicted heat extremes with information on where people actually live within these areas. The paper also finds that, on average, people in high-income countries would experience the same increase in extreme rainfall after 1.0°C of warming that people in low-income countries would experience at 1.5°C of warming.
