According to a new national survey by the Pew Research Center, 63% of Americans say that climate change is harming people in the United States and that climate impacts will get worse over their lifetime. When it comes to the personal impact of climate change, most Americans think they’ll have to make at least minor sacrifices over their lifetime because of climate change, but a relatively modest share think climate impacts will require them to make major sacrifices in their own lives.

The Center survey of 8,842 U.S. adults conducted Sept. 25-Oct. 1, 2023, finds that 43% of Americans think climate change is causing a great deal or quite a bit of harm to people in the U.S. today. An additional 28% say it is causing some harm.

Looking ahead, young adults ages 18 to 29 are especially likely to foresee worsening climate impacts: 78% think harm to people in the U.S. caused by climate change will get a little or a lot worse in their lifetime.

About a quarter of Americans (23%) think they’ll have to make major sacrifices in their everyday lives because of climate change. A larger share (48%) expects to make minor sacrifices because of climate impacts and 28% of Americans expect to make no sacrifices at all.
