Various natural processes have caused global warming. Increase in the content of carbon dioxide in the atmosphere is the fundamental cause of global warming. For example, all animals and humans inhale oxygen and exhale carbon dioxide and thus, replace atmospheric oxygen with carbon dioxide. Because of this natural process of respiration, all humans and animals are not only increasing the carbon dioxide content in the atmosphere, but also reducing the content of oxygen in the air. This is the natural process of respiration and there is no fault of animals or humans in this. Anthropogenic causes are the main contributors to global warming. Trees replace carbon dioxide with oxygen, but they are being readily cut down by humans. Also, as the population is growing, more and more vehicles are crowding the roads. Fuel that burns in them generates such greenhouse gases into the atmosphere as carbon dioxide (CO2), methane (CH4) and nitrous oxide (NO). Increase in the content of greenhouse gases in the atmosphere directly increases global warming. Global warming is a real problem. This can be estimated from the enormous increase in the content of carbon dioxide in the atmosphere that has occurred over the centuries. The following figure displays the rise in carbon emissions into the atmosphere since 1751. Emissions of carbon from 1751 to 2000 (Deem).

How will regional climate be affected? How will the global climates be affected? The terrain, latitude and altitude affect the climate of a particular geographical location. The nearby bodies of water and the flow of their currents also affect it. Climate includes calculations of temperature; humidity, atmospheric pressure, wind, rainfall, and particle count within the atmosphere.
