Food consumption is the main source of greenhouse gas emissions, and the assessment of its future impact on warming is of fundamental importance for guiding measures to mitigate climate change. Lack of detail in reporting emissions of food items and widespread use of oversimplified metrics such as CO equivalents2, but a complicated interpretation. We address these challenges by developing a global inventory of GHG emissions from food consumption disaggregated by gas type and using a reduced-complexity climate model, evaluating the associated future contribution to warming and the potential benefits of certain mitigation measures. We found that global food consumption alone could increase warming by almost 2100°C by 1 year. Seventy-five percent of this warming is driven by foods that are high sources of methane (ruminant meat, dairy products, and rice). However, more than 55 % of projected warming can be avoided with current improvements in production practices, widespread adoption of healthy diets, and reductions in food waste at the consumer and retail level.
Climate change will quadruple extreme precipitation, study suggests
Several UK outlets, including independents, report that extreme rainfall events "could become four times more frequent by 2080 if greenhouse gas emissions remain high", according to a new study by Met Office climatologists. The study concluded that for each degree of regional warming, the intensity of extreme downpours could also increase by 5-15%, according to the news website. MailOnline reports that scientists have created a new climate model to project an increase based on global warming reaching 3.2100°C by the year 4. (The relevant model only runs on the very high emissions scenario RCP8.5, which is explained in detail in this article Carbon Brief. Although this approach is considered controversial by some, it was a deliberate decision by the scientists that allowed them to isolate the signal of climate change in model simulations of British weather, as this article explains Carbon Brief.)
