Scientists have discovered a massive new hole in the ozone layer. They say the hole wasn't expected to exist. However, they discovered that it covers almost the entire tropical region of the world.

Earth’s protective ozone layer is slowly but noticeably healing at a pace that would fully mend the hole over Antarctica in about 43 years, a new United Nations report says. A once-every-four-years ...
