Does ‘net zero’ mean zero cows
A significant share of anthropogenic global warming comes from livestock production. There is debate about whether there can be any role for livestock in a climatically sustainable future; the debate is particularly heated for cows and sheep, largely due to the methane they burp out. However, short-lived gases like methane affect climate in a fundamentally different way than long-lived gases like carbon dioxide. Consequently, climate stabilizatio…
Are single global warming potential impact assessments adequate for carbon footprints of agri-food systems
The vast majority of agri-food climate-based sustainability analyses use global warming potential (GWP 100 ) as an impact assessment, usually in isolation; however, in recent years, discussions have criticised the 'across-the-board' application of GWP 100 in Life Cycle Assessments (LCAs), particularly of food systems which generate large amounts of methane (CH 4 ) and considered whether reporting additional and/or alternative metrics may be more …
Plant power
Burning of biomass such as wood pellets for energy has the potential to contribute to the portfolio of solutions to the climate crisis. Considered over a time span of a few decades, sustainably sourced biofuels can be considered a renewable energy source, with net zero associated emissions of carbon dioxide. However, whether or not biofuels realize this potential depends very much on the way they are sourced, and this involves an intricate and di…
Demonstrating GWP
The atmospheric lifetime and radiative impacts of different climate pollutants can both differ markedly, so metrics that equate emissions using a single scaling factor, such as the 100-year Global Warming Potential (GWP 100 ), can be misleading. An alternative approach is to report emissions as 'warming-equivalents' that result in similar warming impacts without requiring a like-for-like weighting per emission. GWP*, an alternative application of…
Meat consumption, health, and the environment
The future of meat Meat consumption is rising annually as human populations grow and affluence increases. Godfray et al. review this trend, which has major negative consequences for land and water use and environmental change. Although meat is a concentrated source of nutrients for low-income families, it also enhances the risks of chronic ill health, such as from colorectal cancer and cardiovascular disease. Changing meat consumption habits is a…
Climate impact of beef
An analysis of the climate impact of various forms of beef production is carried out, with a particular eye to the comparison between systems relying primarily on grasses grown in pasture (‘grass-fed’ or ‘pastured’beef) and systems involving substantial use of manufactured feed requiring significant external inputs in the form of synthetic fertilizer and mechanized agriculture (‘feedlot’beef). The climate impact is evaluated without employing met…
Abrupt Climate Change
Large, abrupt, and widespread climate changes with major impacts have occurred repeatedly in the past, when the Earth system was forced across thresholds. Although abrupt climate changes can occur for many reasons, it is conceivable that human forcing of climate change is increasing the probability of large, abrupt events. Were such an event to recur, the economic and ecological impacts could be large and potentially serious. Unpredictability exh…
