Ozone layer

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.

However, according to Canadian researcher Ching-Bin Lu, it has been around since the 1980s. It is estimated that the hole has existed since the eighties, but only now has its large size been realized.

The ozone hole has shrunk thanks to the ban on harmful chemicals. This is clear from a NASA study, Nova TV reported.

The chief source of new problems is solutions to old problems. The ammonia that we used in domestic fridges as a coolant in the early-20th century was poisonous if it leaked, so in the 1930s we replaced it with chlorofluorocarbons (CFCs), which you can breathe all day without harm. Problem solved.

Turkey is set to sharply cut its imports of substances that damage the Ozone layer, due to the United Nations' Montreal Protocol, the Environment Ministry has announced.

NEW YORK - Serbian President Tomislav Nikolic has said that developed countries are responsible for ozone layer depletion and global warming, but they now want to establish rules that poor countries will not be able to adhere to.

BELGRADE - Serbia is doing everything it can to enact new regulations that will limit the use of materials that damage the ozone layer, Serbia's Minister of Agriculture and Environment Protection Snezana Bogosavljevic-Boskovic said on September 16, the International Day for the Preservation of the Ozone Layer.

Earth’s protective ozone layer is beginning to recover, largely because of the phase-out since the 1980s of certain chemicals used in refrigerants and aerosol cans, a U.N. scientific panel reported Sept. 10 in a rare piece of good news about the health of the planet.
