Global Warming Thesis Statement Examples

Ozone has been the most reactive form of molecular oxygen and the fourth most powerful oxidizing agent. It has a pleasant concentration at about 2 ppm or less, but higher concentration is irritating. It is used as a disinfectant and bleaching agent. In nature O3 is formed in the stratosphere when ultraviolet light strikes an oxygen molecule.

A photon splits the oxygen molecule into two highly reactive oxygen atoms O.

These combine quickly with an oxygen molecule to form ozone. The O3 readily absorbs UV light and dissociates into its constituent components. Being a natural constituent of the stratosphere, O3 is regularly formed and destroyed in a cyclic manner with solar radiation as the driving force.

In the absence of any other disturbances, O3 settles into a dynamic steady state in which the rate of its formation is equal to the rate of its destruction. Ozone works like an umbrella and protects from the harmful UV radiations coming from cosmic rays to earth. In spite of being a trace gas, it plays a major role in the maintenance of climate and biology of earth.

It filters out all radiations below A0 UV-B radiations that are biologically harmful, and controls the heat budget of the earth. Anthropogenic damage to the ozone layer: While most of the source gases are of natural origin, others have been introduced in nature by man.

It was thus realized that there is a growing probability of damage to ozone layer by human activities.

In early seventies, supersonic transport was the chief cause of NOx radical output into the stratosphere. Considering all other changes in trace gas system e. Development of the phenomenon occurred parallel to the increase of the atmospheric chlorine content produced by the emission of CFCs.

The ozone destroying processes in that region influence the ozone, region of the whole southern hemisphere. Since the early seventies, when CFCs came into market, a large quantity has been injected into the atmosphere.

We can give you some good examples of thesis statements about global warming. High solar activity is a serious effect of ozone layer depletion. Cosmic radiation threatens us because of ozone layer depletion.

Oxygen quantity reduction can cause greenhouse effect. The Earth's ozone layer ozone layerThe region of the stratosphere containing the bulk of atmospheric ozone. The ozone layer lies approximately kilometers ( miles) above the Earth's surface, in the stratosphere.

Depletion of this layer by ozone depleting substances (ODS) will lead to higher UVB levels, which in turn will cause increased . Ozone depletion describes two related events observed since the late s: a steady lowering of about four percent in the total amount of ozone in Earth's atmosphere (the ozone layer), and a much larger springtime decrease in stratospheric ozone around Earth's polar regions.
