Maine Public News -  The next time you shop for a cooking stove, the gas versions might show a health warning label similar to those on tobacco products. Because a stove's blue flame releases air pollution into your kitchen, California lawmakers have passed a bill that would require such warning labels on gas stoves for sale in stores and online. Gov. Gavin Newsom has until the end of September to sign the bill into law.The legislation comes after a series of lawsuits was filed against stove manufacturers, claiming they should have warned customers about potential health risks. Environmental activists are encouraging people to switch to electric stoves, part of a broader campaign to cut climate pollution from buildings.
