A majority of Americans — 74% — believe the government should encourage schools to include climate change in the curriculum, according to a recent Heatmap News poll. But despite widespread support, only a slim majority of states earned a grade of B+ of better for science standards.

New Jersey earned a B+, according to a 2020 analysis from the National Center for Science Education and the Texas Freedom Network Education Fund. Since then, New Jersey has become the first state to require climate change be taught across subjects, not just in science classes.

The state’s new standards aim to teach students about what causes climate change, how climate change impacts local and global communities and how students can practice sustainability. They first went into effect in the 2022-2023 school year.
