Ozone-depleting substances caused half of late 20th-century Arctic warming, says study

Scientists determined the cause to be ozone-depleting substances—long-lived artificial halogen compounds. Although the ozone-destroying effects of these substances are now widely understood, there has been little research into their broader climate impacts.
