A growing body of research suggests that humans are changing the environment in ways that are having profound effects on our health and our planet.
A new survey of 5,000 people by the University of Michigan and the American Association for the Advancement of Science (AAAS) found that for the first time in the last two decades, more Americans than ever said they were concerned about climate change.
And the findings suggest that this fear isn’t just about carbon emissions, but also about our health.
In the last year, a new survey by the AAAS and the University at Buffalo found that a third of Americans have been at risk of dying from climate-related diseases due to their increased use of fossil fuels, which has been blamed for a rise in asthma, allergies, depression, obesity, and other illnesses.
The survey found that nearly half of Americans (47 percent) say they have seen or heard of climate change, up from about one-third in 2012.
More than half (55 percent) of Americans say they believe climate change is a “real and serious problem,” up from 38 percent in 2012, according to the survey.
A large proportion of Americans are concerned about their own health, and they are more likely than others to see climate change as a threat than they are as a positive thing.
For example, nearly three-quarters (76 percent) said that they believe human activity is a major threat to the health of the nation, up slightly from 74 percent in 2011.
In a survey conducted by the National Institute on Aging in January, about a quarter of Americans said that climate change was a serious problem, while the rest said it was not a major problem.
And about two-thirds (66 percent) believed that climate changes would cause more extreme weather events, up sharply from 62 percent in 2009.
While these trends are troubling, they aren’t necessarily unprecedented.
In fact, in the 1990s, the percentage of Americans who believed climate change would cause an increase in extreme weather was lower than today’s, according an analysis by the Pew Research Center and the Yale School of Forestry and Environmental Studies.
For the first five years of this century, climate change became the number one concern for most Americans, the Pew report found.
The trend was reversed by the turn of the century, however, when climate change took a backseat to the threat of the pandemic.
The year 2000 saw the worst year for extreme weather in at least a century, with severe thunderstorms and floods that killed more than 1.3 million people.
By 2017, the number of Americans worried about climate changed increased to more than four in ten.
In 2018, the AAAs survey found climate change to be the top concern of the majority of Americans, followed by an increasing number of people concerned about rising temperatures.
And it was the number two concern in 2020.
More than four-in-ten (41 percent) Americans in 2020 believed climate changes were likely to cause more severe weather events than they had in recent years, a sharp jump from 21 percent in 2016.
And while climate change has been the focus of recent policy discussions, it is likely to remain a hot-button issue for a long time to come.
The issue is particularly sensitive in the 2020s, as Americans are beginning to look at the science behind the changing climate.
In 2020, only 13 percent of Americans were confident that global warming was occurring in a way that was causing them serious problems, while more than a quarter (27 percent) were skeptical of the possibility of human-caused global warming.
More Americans believe climate changes are not a threat to their health than do the public at large, according a Pew poll conducted in 2016, before Trump was elected president.
And more than half of the public believes that climate science is reliable and up to date, compared with just 30 percent of the general public.
Still, climate issues are increasingly seen as a major issue by Americans, and there are several trends that suggest that Americans are likely to take more seriously their health and environment concerns as the climate continues to change.
The rising tide of climate-induced wildfires has made wildfires more intense in the past few decades, and climate change could be responsible for more of those fires in the future, according the University and Cornell University researchers.
And a new study published in the Proceedings of the National Academy of Sciences found that, even though climate change caused wildfires in the 1930s and 1940s, they did not become as severe or more frequent until after World War II.
In other words, fires may be less of a threat today because of the climate.
As climate change continues to become a major concern in the US, Americans are taking more seriously the health and environmental impacts of climate.
