There’s something weird going on with the Earth’s atmosphere. Scientists have found that a man-made gas banned long ago in a global agreement to save the ozone layer is mysteriously reappearing. But they’re not sure where it’s coming from.

Atmospheric measurements in Hawaii show that an ozone-depleting gas called CFC-11 is decreasing at a slower rate, which shouldn’t be the case if all the countries that signed on to the 1987 agreement are following the rules, a study published in the scientific journal Nature says.

“The evidence points to an increase in emissions nearly 10 years after the production was supposedly phased out, so it was very much a detective story for us to try to unravel,” said Stephen Montzka, a scientist at the National Oceanic and Atmospheric Administration and one of the study’s authors, told VICE News.

In 1987, 197 countries signed the Montreal Protocol, which set goals for decreasing the production of ozone-depleting chemicals like chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs). A complete ban on the production of new CFCs began in 2010. Any new CFC production has to be reported to the United Nations Environment Programme. And the agreement has worked pretty well. A January NASA study found that there was 20 percent less ozone lost during the 2016 Antarctic winter than there was in 2005.

The ozone layer absorbs most of the sun’s UV rays and keeps them from reaching Earth. A change in the amount of UV rays making it through the atmosphere would be really bad for humans, plants, animals — anything that’s alive. UV radiation damages DNA, and can cause skin cancer and cataracts in people. The State Department says full implementation of the Montreal Protocol could prevent as many as 280 million cases of skin cancer in the U.S. alone by the end of the century.
