Global Warming: A Comprehensive Analysis

Global warming is a hike in average temperature of the earth due to excessive green house gases in the atmosphere and depletion of ozone layer in the stratosphere.
It is the vital and chronic disease of earth, where we human lives in. The relationship of human being with earth are predator since decades. We exploit natural resources of earth and in return we are harming it.
Uncontrolled emission of Nitrous oxide (N[SUB]2[/SUB]O) , Carbon Dioxide (CO[SUB]2[/SUB]) , Methane (CH[SUB]4)[/SUB] and Chlorofluorocarbon (CFC) by vehicles, factories and deforestation led us to thickening of green house effect and thinning of ozone layer, which consequently cause global warming.
It dates back to industrial revolution , in the late 18[SUP]th [/SUP]century, the introduction of machine into human society, to reduce human effort and increase productivity, in terms of agriculture, textile, mining and transportation. It had a profound effect on social, cultural and economic conditions. It had begun in United Kingdom and then subsequently spread throughout Western Europe, North America, Japan and to the rest of the world. Initially industries had been kicked off to produce more goods and cope with their individual territorial demands. Later on expansion of trade, emerged Commerce Revolution- which led them to opened trade route for selling their goods and to import raw material to generate finished goods and then exchanged with other countries. At that time the main source of power to run industry were flowing water, steam, internal combustion- which are the main cause of Green House gases.
The British formula of industrialization stimulated other countries to generate their own products- and here the race of industrialization begun throughout the globe which transpire Second Industrial Revolution- the machine of industrial revolution in the 18[SUP]th[/SUP] and 19[SUP]th[/SUP] century were simple. New scientific techniques unlocked the secrets of physics and chemistry which unfolded the generation of electricity and the use of atomic fission, led them to electrical industry and chemical industry. Human power was replaced by machine power. Electricity enable industrialist to operate their machine on non-stop basis, which further increased emission of hazardous gases into the atmosphere.
The transition from industrialism to post-industrialism- machine to technology, the computer era, led by United States America. The era in which we live now, headed towards urbanization and consequently over population in major cities of the world.
Despite industrial revolution, in todays world the main causes of global warming are, deforestation. Plants & trees are responsible to absorb CO[SUB]2[/SUB], construction of buildings, expansion of urbanization and burning of woods as a fuel are the sources of deforestation. Increase in number of vehicles and factories to cope up with the demands caused by over population.

CO2 levels usually bottom out in late September or early October before the exhale of CO2 begins. Levels at this exhale point have always dropped below 400 parts per million (ppm)the milestone at which scientists say it will be difficult to keep climate change in check once crossed. In the next few weeks, when this exhale point is upon us once again, we could very well cross that milestone and bid farewell to a sub-400 ppm world once and for all. Source: Forbes
The negative impacts of global warming are, glacier melting, which makes rise in sea level, the conversion of land into sea (subduction of continental into oceanic crust). Rise in sea level has a great threat to Persian gulf and gulf of Mexico. Unusual thunderstorms, rainfall, cyclones, tsunamis, hurricanes are the signs of global warming. It destroy coastal human population, marine ecosystem, acidification, disturbance in mangroves forest. On top of that if the current rate of warming not properly mitigated the Islands throughout the world are vulnerable to sink in sea in coming decades.
To mitigate global warming there are several ways which an individual can input; these are tree plantation, reduce, re-use, re-cycle all the waste. Turn off electric devices when not in use.
The main emitters of green house gases are china and United States America together responsible for 40% of the worlds carbon emission into atmosphere. Recently In September 2016, leaders of G20 gathered at Hangzhou, China ratified the Paris climate agreement, which is considered the first ever deal in the history regarding climate change.

Paris agreement: Key points

  1. [*=1] To keep global temperature increase "well below" 2C and to pursue efforts to limit it to 1.5C
    [*=1] To peak greenhouse gas emissions as soon as possible and achieve a balance between sources and sinks of greenhouse gases in the second half of this century
    [*=1] To review progress every five years
    [*=1] $100bn a year in climate finance for developing countries by 2020, with a commitment to further finance in the future.
    [*=1] Once the deal comes into force, countries that have ratified it have to wait for a minimum of three years before they exit
It is an unprecedented step towards control on climate change. Sustainable development and awareness are the major needs to deal with this issue. Let the planet earth be impeccable for future generation.
