Global Warming

Global Warming

A simple definition of global warming is that over the past 50 years, the average global temperature has increased at the fastest rate in recorded history, experts see the trend is accelerating. All but one of the 16 hottest years in 134 years of NASA’s record have occurred since 2000.

Some people say that there had been a pause or slowdown in rising global temperatures. But there are several recent studies and researches which denied this claim of these peoples. It has been observed that temperature of United States has been increased up to 10 degrees Fahrenheit.

List of Causes/Reasons of Global Warming

The causes/reasons of Global Warming can be divided into two major categories which are Natural causes and Man-made causes.

Natural Causes

Natural causes are playing a vital role in the global warming which is as follows:-

Spots on the Sun

There are dark spots on the surface of the sun which block hot solar plasma. Though this action might appear to decrease solar radiation, the opposite is true. On the surrounding of sunspots, there are bright patches named as faculae. These spots give off greater than normal radiation, and they are more influential than the darker, cooler spots. This means that the total energy over a 30-day solar rotation rises.

Permafrost

There is another natural reason for global warming which permafrost. It is actually a solidly frozen soil which consists of about twenty-five percent of the land area of this planet. According to a study, permafrost has locked the carbon and methane under the surface of the planet. In some areas of permafrost carbon is emitting which can potentially increase its effect on greenhouse as well may cause the boost in global warming due to the atmospheric carbon.

Vapor of Water

Carbon Dioxide induced warming by water vapor in the atmosphere. As per the studies of the NASA that two third of the heat trapped by the green house is contained in water vapor.

Causes due to Man

Global warming is increasing due to increase in greenhouse gases which trap or absorb some infrared radiations emitting from the planet. There is some man made causes which are as follows:-

Sweltering of Vestiges and Fuels (Gases, Oil, Petroleum)

Carbon Dioxide is actually the main source of global warming and most of the carbon dioxide produced by burning of fossils and fuels. When you burn fossils and fuels, the level of carbon dioxide increases which absorb the infrared energy emitted from earth, preventing it from returning to space.

Production of Electricity

Production of Electricity is another way of production of Carbon dioxide. Electricity is being produced by burning fossils, fuel and coal which produces plenty of carbon dioxide. Coal is the great emitter of carbon dioxide.

Vehicles

Transportation system all over the world consists of cars, trucks, airplanes, trains etc. These all vehicles/automobiles use gasoline, petrol, diesel etc which is the great cause of an increase of the level of carbon dioxide and ultimately global warming.

List of Effects of Global Warming

There are several effects of global warming, significant issues due to global warming are as follows:-

Glaciers are melting in all over the world

Global warming has become the reason for early snowmelt. Due to this, there may be a shortage of water and risk for wildfires.

Rise in the Sea Level

Due to increase in global warming glaciers go for melting which causes the flood in the river. The water of this flooded river goes into the sea which is the main reason for the rise in sea level.

Trouble for farms, Forest, and Cities

Global warming causes the heat waves off the way means un- seasonal heat which are harmful to farms, forests, and people living in cities.

Environmental Disturbance

Disturbance of environments such as coral ridges and Hilly Meadows could drive many plant and animal species to extinction.

Outbreak of Many Diseases

Asthma, Allergies and infectious disease outbreaks will become more communal due to increased growth of pollen producing ragweed, higher levels of air pollution, and the spread of conditions favorable to pathogens and mosquitoes.
