The increasing abundance of green house gases in atmosphere has led to the following effect except A. Global warming B. Depletion of ozone layer in the stratosphere C. Oxygen fertilization effect D. Carbon dioxide ferilization effect

The correct answer is C. Oxygen fertilization effect.

Greenhouse gases trap heat in the atmosphere, which causes the Earth’s temperature to rise. This is known as global warming. The depletion of the ozone layer in the stratosphere allows more ultraviolet radiation to reach the Earth’s surface, which can cause skin cancer and other health problems. Carbon dioxide fertilization effect is the idea that increased levels of carbon dioxide in the atmosphere can increase plant growth. However, this effect is not well-understood and may not be significant enough to offset the negative effects of global warming.

Oxygen fertilization effect is the idea that increased levels of oxygen in the atmosphere can increase plant growth. However, this effect is not well-understood and may not be significant enough to offset the negative effects of global warming.

Global warming is the long-term heating of Earth’s climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth’s atmosphere. The term is frequently used interchangeably with the term climate change, though the latter refers to both human- and naturally

The ozone layer is a region of Earth’s stratosphere that absorbs most of the Sun’s ultraviolet radiation. It contains high concentrations of ozone (O3) relative to other parts of the atmosphere, although still small in relation to other gases in the stratosphere. The ozone layer contains less than 10 parts per million of ozone, while the average ozone concentration in Earth’s atmosphere as a whole is about 0.3 parts per million. The ozone layer is mainly found in the lower portion of the stratosphere, from approximately 20 to 30 kilometers (12 to 19 mi) above Earth, although its thickness varies seasonally and geographically.

The carbon dioxide fertilization effect is the idea that increased levels of carbon dioxide in the atmosphere can increase plant growth. Carbon dioxide is a plant nutrient, and plants use it to produce food through photosynthesis. When there is more carbon dioxide in the atmosphere, plants can grow faster and produce more food. However, the carbon dioxide fertilization effect is not well-understood and may not be significant enough to offset the negative effects of global warming.
