Greenhouse gas emissions released by human activities are causing Earth's average temperature to warm, according to NASA.
However, some social media users are sharing a post that implies humans are not responsible for this warming, positing instead that Earth is being warmed by a force also causing purported warming on other planets.
"As the Earth has warmed over the last 100 years, so too have Jupiter, Neptune, Mars and Pluto," reads the caption of an Oct. 25 Facebook post.
The post garnered more than 200 shares in a month.
But the claim is wrong.
While Earth has exhibited a clear warming trend over the last 100 years, temperature records for the other planets mentioned in the social media post do not extend that far back, meaning there's no way to prove this claim. Further, there is no evidence of recent warming on Jupiter, Neptune or Mars, according to researchers.
"The simplest problem with these claims is that it is extremely difficult to measure temperatures at other planets remotely," Luke Moore, a professor and planetary scientist at Boston University, told USA TODAY in an email. "Therefore, making any definitive claim similar to what is posted (in the meme) is disingenuous and deceptive."
USA TODAY reached out to the Facebook user who shared the post for comment.
