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.

According to a new study published in the journal Geophysical Research Letters, warming ocean waters have caused a drop in the brightness of the earth.

Researchers measure the earth’s albedo by observing the light reflected from earth that illuminates the surface of the moon as well as with satellite measurements. The earth reflects about 30% of the sunlight that shines on it.  The data shows that the earth now reflects about half a percent less light than it did 20 years ago, with most of the drop occurring in the last three years.  That number had been fairly constant for most of the past 20 years.

According to the researchers at the New Jersey Institute of Technology, New York University, and a Spanish astrophysical agency, the apparent cause of the albedo drop has been a reduction of bright, reflective low-lying clouds over the eastern Pacific Ocean in most recent years.  That is the same area off the west coasts of North and South America where increases in sea surface temperature have been observed because of the reversal of a climate condition called the Pacific Decadal Oscillation, which is likely a result of global climate change.

The dimming of the earth implies that more solar energy is being absorbed rather than reflected, which may contribute further to global warming.

These results are somewhat surprising.  Scientists had postulated that the warming of the earth could lead to more clouds and therefore a higher albedo – more reflection of the sun’s light.  If that were the case, it would help to moderate warming and balance the climate system.  These new results indicate that the opposite is true.

Using Less Water

In recent times, there has been a downward trend in water use in the United States.  It has been driven by increasingly efficient use of critical water resources in the face of persistent droughts in various parts of the country and awareness of the importance of conserving this resource.
