This report from the UK’s Committee on Climate Change (CCC) sets out the UK’s current progress towards its climate goals. It finds that, since June 2018, the UK government has only delivered 1 out of 25 essential policies needed to cut emissions and only 7 out of 24 progress indicators are on track.

Methane emissions from ammonia fertiliser manufacturing plants (which use natural gas as a feedstock and energy source) in the United States are around one hundred times higher than currently reported levels, according to this study. Researchers used a Google Street View car equipped with methane analysers to take measurements downwind of six ammonia fertiliser plants (there are only 23 such plants in the US).

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.

Decoupling of carbon emissions from economic growth is unlikely to happen quickly enough to meet the Paris climate targets of limiting warming to 1.5°C or 2°C, according to this paper. Furthermore, both historical trends and model-based projections suggest there is no evidence that resource use and economic growth can be absolutely decoupled at the global scale in the context of continued economic growth.

This paper, by John Lynch of the University of Oxford’s LEAP project, finds that carbon footprint studies of beef cattle typically do not report separate values for emissions of different greenhouse gases such as methane and nitrous oxide. Instead, studies generally report only an aggregated figure in the form of the 100-year Global Warming Potential (GWP100) as CO2-equivalent.

This paper uses economic models to calculate the extent to which both supply-side and demand-side measures could reduce non-CO2 greenhouse gas emissions from the agricultural sector, depending on carbon price.

The ongoing government shutdown in the United States means that several databases and websites with agricultural and climate data are currently unavailable. Gro Intelligence is offering free subscriptions to its web app during the shutdown. The web app provides global food and agriculture data.

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.

A recording of the launch of the report “Negative Emissions Technologies and Reliable Sequestration: A Research Agenda” can be viewed here, hosted by the National Academies of Sciences, Engineering, and Medicine. The video is around one hour long and includes an overview of the report’s findings and a question-and-answer session.
