IPCC International Panel on Climate Change attributes global warming to the increase of greenhouse gases as Arvind Singh accurately portrays. The documentation of the panel attributes the increase of greenhouse gases to the escalating use of fossil fuels on a global basis. They cite models base on the greenhouse gases which describe the actual warming and predicts scenarios of change based on policy to reduce the combustion of fossil fuels. Beside a recommendation to aggressive reduce greenhouse gas evolution the panel suggests sequestration the removal of atmospheric greenhouse gases will be needed to return to more steady state climate without escalating global temperatures. The residence or half lives of greenhouse gases can be over a hundred years suggesting even with conclusive measures in fossil fuel reduction and sequestration the reduction of global warming might take generations.

Global warming refers to the increase in temperature of Earth. This increase has been between 0.3º C and 0.8º C over the 20th century. The chief cause of global warming is the phenomenon ‘green house effect’ in which certain atmospheric gases are transparent to incoming short-wave solar radiation but are opaque to outgoing long-wave terrestrial radiation consequently leading to rise in earth’s temperature. These gases are known as green house gases, which includes carbon dioxide (CO2), methane (CH4), chloroflurocarbons (CFCs), nitrous oxide (N2O), trophospheric ozone (O3) and water vapour. Owing to continued addition of these gases in the atmosphere the danger of climate change has increased.

The natural green house effect is essential for life on the earth as it is responsible for maintaining the earth at a salubrious +15ºC on the average, compared to dead frozen -19ºC that would have been the case in absence of green house gases.

Man is considered as engine of climatic change. Paddy farmers, dairy farmers, coal miners and shifting agriculturists contribute their might in global warming. According to some estimates paddy cultivation in the world is responsible for 20 per cent methane being added to atmosphere and the coal mining accounts for 6 per cent of methane. The deforestation is responsible for 20 per cent of carbon dioxide gas being added to the atmosphere. Similarly, industrialization is adding 25 per cent of chloroflurocarbons to the aerosol of the atmosphere. Consequently global temperature rise is by about 1.5ºC

Dear @Arvind Singh, many thanks for your reply. I would appreciate it if you could also recommend some literature sources supporting your informative answer. Best

Dear Aryan Shahabian,

Please have a look at the following PDF attachment.

Thanks!

Dear @Paul Reed Hepperly, Many thanks for your detailed reply.

@Paul Reed Hepperl @Arvind Singh

Would you please also shed some light on the difference between climate change and global warming, and their relation with sustainability?

Our increase in greenhouse gases has been conclusively linked to fossil fuel combustion as the source of the increase. Fossil fuels namely coal, petroleum and natural gas are being used at rates above their replacement naturally. Such resources which can result are being used up and are considered to be non renewable in their nature.

In contrast to nonrenewable resources renewable energy resources can be produced over and over again without depletion. A good example is wind and solar power and biomass.

As the quantity of nonrenewable fossil decreases the economics and environmental impact of these becomes accentuated. The economy and useful of renewable are improving as emphasis is put in to their development.

One way of comparing energy issues among non renewable is to look at the carbon footprint of their production and use. Accounting the nature of our activities and then adjusting accordingly is one way to redress the issues related to excess use of fossil fuels.

Not all human activities are contributors to greenhouse gas issues the management of forest resources can work to withdraw the greenhouse gases from the atmosphere and to improve the environment while producing a renewable energy resource. The use of pyrolysis is cable of producing renewable energy and long term carbon sequestration this is sustainable and renewable way to address climate change and global warming. This transformation would need to be championed demonstrated and evolved and seed funding would be needs to start this important transformation.

Greenhouse gas emissions minus the greenhouse gas sequestrations give a positive difference which contributes to greenhouse gas evolutions, zero would be a steady state and a negative sum the sequestrations overwhelming the emission leads to the ability to withdrawl greenhouse gas combating the source of global warming greenhouse gas in the atmosphere.

@Paul Reed Hepperly Many thanks for your informative reply. I didn't receive an answer to the first question in my previous comment though; Global warming vs climate change. How different are they from your point of view?

Climate change is the movement of weather patterns whether warming or cooling over an extended period of time. Ergo climate change is happening all the time to some extent. In contrast, Global warming refers to a persistent tendency toward hotter climate over some extended time scale.

Since the last Ice Age when there was a period of more cooling than not with low greenhouse gas contents we are currently experiencing persistent unnatural temperature increases or global warming.

The change in warming seems to coincide with the increase of greenhouse gases from human activities first the agricultural revolution starting about 10,000 years ago and accelerating more since the Industrial Revolution which started about 200 years ago in earnest. Both agricultural practices and industrial have led to increased generation of greenhouse gases to the atmosphere.

The previous carbon dioxide values before 200 years ago to about 1,000,000 years ago were in a range of 180 to 280 ppm.

The current reliable carbon dioxide values are 415 ppm rising about 3 to 4 ppm per year in relation to fossil fuel combustion.

The climate pattern since 200 years ago is an accelerated global warming with no evidence that the climate has stabilized or reversed itself.

Before the advent of Agriculture and Industry the effects on climate fluctuation were largely governed by natural variation in solar and volcanoes as factors acting principally in a cyclic fashion with ups and downs.

Apparently now since the Industrial revolution in particular and less so in Agricultural revolution the predominant source of greenhouse gases has been human activities which correlate well with increased temperature regimens we are experiencing.

A warmer air leads into a warmer ocean. Therefore, we get more evaporation and more energy in the air leading to stronger wind, heavier rain, etc (what we call climate change).
