The consistently rising temperature of the earth’s atmosphere is termed as global warming. This rising temperature is largely attributed to human activities and coincided with the massive industrialization of the 19th century. Since then, global temperatures have been steadily rising – a process accelerated in the past three decades by rapid industrialization across the developing world and the increasing concentration of greenhouse gases effected by this industrialization.
Statistically, average global temperatures have shot up by more than 0.8C since the turn of the twentieth century. This is expected to increase exponentially within the coming decades, with estimates ranging from an average increase of 1.1C to 6.4C, although there is no consensus among scientists regarding this figure.
The causes of global warming have been traced to human actions, particularly the excessive burning of fossil fuels and rapid deforestation across the world. Burning fossil fuels release greenhouse gases such as CO2 into the atmosphere. These gases act as an insulating layer, preventing the sun’s heat from reflecting back into space and thus, contributing to increased global temperatures (i.e. like a greenhouse). Rapid deforestation contributes to this process as CO2 consuming vegetative cover is destroyed, leading to an excess of greenhouse gases in the atmosphere.
Global warming presents a particularly pressing challenge to human society, even threatening the very survival of the species. Rising temperatures have been linked to highly unstable climate patterns, melting polar caps and glaciers, which, in turn contributes to rising sea levels and reduced quantities of fresh water. Global warming puts excessive strain on natural systems to sustain a growing human population – a situation that is not sustainable in the long term.
Response to mitigate the effects of global warming have largely focused on reducing the emission of greenhouse gases, increased afforestation and using alternative fuels of energy to reduce our dependency on fossil fuels.
However, most efforts to curb and control global warming have been sabotaged by the politics surrounding the issue. Many advocates of industrialization claim that global warming is caused by natural and not human factors. Additionally, developing countries claim that laws that curb their greenhouse gas emissions are anti-competitive and reduce the efficiency of their industries. Consequently, the intense debate surrounding the issue and the lack of scientific consensus has contributed to poor handling of the global warming crisis.
Global Warming Thesis Statement Examples:
* The politics associated with global warming has sabotaged efforts to curb and control this environmental crisis. The need of the hour is for the various factions to reconcile their differences and work together to retard the effects of global warming.
* The apparent lack of scientific consensus regarding global warming is smokescreen to obfuscate the agendas of oil-reliant industries.
* Global warming, as the term implies, is a global issue and cannot be tackled locally. Thus, international co-operation is the need of the hour if we are to curb and control this phenomenon.
* Greenhouse gas emissions from power plants are one of the largest contributors to rising global temperatures. A greater emphasis on cleaner, alternative sources of energy is the need of the hour to retard the upwards incline of global temperatures.
* Global warming has contributed to wildly unpredictable seasonal patterns.
* Causes lie in one area and the Effect emerges in another area. Hence, global warming is truly a global issue and needs to be tackled collectively by all the nations.
* Deforestation, though in play over the last 20 years, has not caused as much global warming as the emissions of gases from fossil fuels in the Southern African region.
* Global warming is seen to have led to the emergence of new diseases.
