Global warming : Natural or human- induced

Scientists and environmentalists have defined the term global warming in different ways Global warming refers to the heating of the surface which leads to climate change and rising sea levels this is mainly due to emission of gases (www .planningportal .gov .uk . Others attribute global warming to the consequences of the green house effects

It is also believed that global warming occurs when temperatures of the earth surface increase due to rise of carbon dioxide causing climatic

br changes hence global warming . Global warming has in the recent past become a subject of interest among scientists environmentalists and governments among other groups . This is due to the far reaching effects especially the climate change . The question that now begs an answer is whether global warming occurs naturally or it is due to human activities

There has been an increase in global temperature since mid 20th century

There are scientists who hold that global warming is caused by human activities like the emission of gases such as carbon to the atmosphere burning of fossil fuels , deforestations and similar activities (Job D .A 1994

Human activities have been cited as the causes of global warming by environmentalists , who urge for discontinuation of the said activities

Green house gases are highly cited to cause the rise in the temperature of the earth . This is mainly due to anthropogenic GHGs . However this argument is discredited because rising levels of carbon dioxide (CO2 and green house gases GHGs does not correlate with global warming

Some scientists argue that if the green house gases were causing climate changes through temperature rise , then the troposphere would warm faster than the earth surface and this according to them is not observable

Temperature measurement indicate that temperatures increase with the rate of the temperature surface . Temperatures have risen and fallen due to the change in the levels of carbon dioxide in a time span of after 1000 years (Net T . 1999

It is uncertain to attribute global warming to the humans . Global warming is due to the effects of natural occurrence such as ocean currents and when the solar system increases its solar activities

Ocean currents are the movements of ocean water in a continuous way Ocean currents within the ocean of hot or cold rivers . Forces generate currents which acts upon water causing planet rotation , wind affects the temperatures , this leads to differences in the moon gravitation

Ocean currents may flow for long distances even thousands of kilometers . They determine the climates in areas surrounding the oceans Some examples are the Hawaiian Islands where the climate of the area is cool than the tropical latitudes . Deep ocean currents are driven by destiny and temperature gradient

Global warming is mostly believed to be caused by human activities Some researchers have tried to examine patterns of heat in the temperature warming over land and water in both warm and cold areas Results revealed some specific patterns regarding the green house...
