Ozone depletion is not a primary cause of climate change, however there exists a physical science connection between the two phenomena. The Earth's atmospheric ozone has two major effects on the Earth's temperature balance. Firstly, it absorbs solar ultraviolet radiation, leading to the heating of the stratosphere.
Conversely, ozone depletion represents a radiative forcing of the climate system. There are two opposing effects: Reduced ozone causes the stratosphere to absorb less solar radiation, thus cooling the stratosphere while warming the troposphere; the resulting colder stratosphere emits less long-wave radiation downward, thus cooling the troposphere.
This cooling is projected to result in a relative rise in ozone (O 3) depletion in the polar region, as well as an increase in the frequency of ozone holes. [36] Ozone depletion, on the other hand, is a radiative forcing of the climate system. Two opposite effects exist: Reduced ozone causes the stratosphere to absorb less solar radiation ...
The ozone layer is on track to fully recover from its depletion within the next four decades, a panel of scientists gathered by the United Nations said on Monday. U.N.: Depletion of ozone layer ...
The scientific community has been investigating the causes of climate change for decades. After thousands of studies, it came to a consensus , where it is "unequivocal that human influence has warmed the atmosphere, ocean and land since pre-industrial times."
A recent report from the United Nations included some dire news about the fight against climate change. It said current pledges from countries to curb emission will probably not stop global ...
The Montreal Protocol on Substances That Deplete the Ozone Layer is an international treaty designed to protect the ozone layer by phasing out the production of numerous substances that are responsible for ozone depletion. It was agreed on 16 September 1987, and entered into force on 1 January 1989.
In 1995, Baliunas testified before the United States House Science Subcommittee on Energy and Environment that CFCs were not responsible for ozone depletion. [23] An article written by Baliunas and Soon in 2000 for the Heartland Institute , a conservative and libertarian public policy think tank, promoted the idea that ozone depletion rather ...
