Just say ‘climate change’

September 20, 2024 By EarthWise Leave a Comment

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.

The Cost Of Heat Waves | Earth Wise

December 7, 2022 By EarthWise Leave a Comment

Heat waves are defined as periods of abnormally hot weather generally lasting more than two days. To be considered a heat wave, the recorded temperatures must be substantially above the historical averages for a given area. According to climate scientists, anthropogenic climate change is likely causing heat waves to increase in both frequency and intensity.  

According to a new study by researchers from Dartmouth University, climate change-driven severe heat waves have cost the world economy trillions of dollars since the early 1990s. 

In the study, which was recently published in the journal Science Advances, researchers combined in-depth economic data for regions worldwide with the average temperature for the hottest five-day period —a commonly used measurement of heat intensity—for each region in each year.  The research team found that between 1992 and 2013, heat waves statistically coincided with variations in economic growth and that an estimated $16 trillion was lost to the effects of high temperatures on human health, productivity and agricultural output.

The results of the study underscore issues of climate justice and inequality.  According to researchers, the economic costs of extreme heat have been and will be disproportionately borne by the world’s poorest nations.  While economic losses due to extreme heat events averaged 1.5% of GDP per capita for the world’s wealthiest regions, the researchers found that low-income regions suffered a loss of 6.7% of GDP per capita.  Most of these low-income nations have contributed the least to climate change. 

According to the research team, immediate action is needed now to protect vulnerable people during the hottest days of the year.
