Just say ‘climate change’

In recent years, climate advocates have pushed for the use of more dramatic language to describe ‘climate change.’ The notion was that phrases like ‘climate crisis’ and ‘climate emergency’ better convey the urgency of the planet’s plight, while terms like ‘climate change’ and ‘global warming’ are too gentle and vague. However, it turns out that the gentler approach may actually be more effective.

According to a new study led by researchers from the University of Southern California, the terms ‘climate change’ and ‘global warming’ are not only more familiar to people than some of their common synonyms, but they also generate more concern about the warming of the Earth.

In the study, which was recently published in the journal Climatic Change, the research team found that nearly 90% of respondents were familiar with the terms ‘climate change’ and ‘global warming.’ However, familiarity dropped sharply for the other terms, including ‘climate crisis’ and ‘climate emergency.’ In fact, only 33% of respondents recognized the term ‘climate justice.’

The study, which surveyed more than 5,000 randomly selected U.S. residents, examined the degree to which each term generated concern, urgency, willingness to support climate-friendly policies, and willingness to eat less red meat.

The research team found that the terms ‘climate change’ and ‘global warming’ were most concerning and most urgent. ‘Climate justice’ was the least, with ‘climate crisis’ and ‘climate emergency’ falling in between. The support for climate policy and willingness to eat less red meat was roughly the same, regardless of what terms were used.

The research team hopes its findings will help us communicate more effectively about climate change in the future.

Small changes can yield big results

Global food production is one of the largest contributors to climate change. In fact, one-quarter of the world’s greenhouse gas emissions result from food production and agriculture. Be that as it may, we still have to eat. But what we choose to eat has a major impact on the environment.

According to a new study by researchers at McGill University in Canada and the London School of Hygiene & Tropical Medicine in the U.K., partially replacing red and processed meat with plant-based proteins can increase lifespan and mitigate climate change.

In the study, which was recently published in the journal Nature Food, the researchers drew data from a national nutrition survey to analyze Canadians’ dietary records. The study modeled partial replacements (25% and 50%) of either red and processed meat or dairy with plant protein foods like nuts, seeds, legumes, and tofu, on a combination of nutrition, health, and climate outcomes.

In the study, the researchers found that a person’s diet-related carbon footprint plummets by 25% when they replace half of their intake of red and processed meats with plant protein foods. However, dairy substitutions showed smaller reductions of up to just 5%.

Meat and dairy-rich diets are known to increase the risk of heart disease, diabetes, and certain cancers. The researchers also estimated that if half of the red and processed meat in a person’s diet was replaced with plant protein foods, life expectancy would increase nearly nine months on average, due to a reduced risk of chronic disease.

The research team hopes its findings will help people make healthier and more sustainable food choices.

Fast Food And Climate Change

March 1, 2019 By EarthWise 1 Comment

A coalition of global investors is urging some of the largest fast food companies to reduce greenhouse gas emissions. The group, which has approximately $6.5 trillion under management, wants the fast food chains to reduce the carbon footprint of their meat and dairy supply chains.

The global fast food sector is reportedly worth a whopping $570 billion annually. The coalition has targeted some of the most notable contributors to that figure, including McDonald’s, KFC, Domino’s, Wendy’s, Burger King, Pizza Hut, and Chipotle.

According to the investors, animal agriculture is one of the world’s highest-emitting sectors without a low-carbon plan. If left unchecked, emissions from animal agriculture alone would contribute 70% of the total worldwide target for emissions in 2050 that would keep the global rise in temperature below 2C. Animal agriculture also uses an estimated 10% of annual global water flows.

In their letter to the fast food giants, the investors are calling on the companies to implement clear requirements for suppliers of animal proteins to report and reduce their greenhouse gas and freshwater impacts. They want fast food companies to publish quantitative, time bound targets for reductions, and commit to publicly disclose the progress on these targets.

Climate change is increasingly a factor for investors when evaluating market risk. This investor letter comes just weeks after the EAT-Lancet commission report was published, in which their experts suggest that a sustainable diet for the planet by 2050 will require a 90% reduction in red meat and milk consumption.

Fast food may need to slow down.
