Global warming is caused by a variety of factors, but perhaps the most critical contributing factor is the carbon dioxide that has been released slowly to the atmosphere for the past 400,000 years. The Industrial Revolution at the turn of the 20^th century greatly increasedcarbon dioxide emission.

In this age of business travel, burnt fuel from the planes is actually contributing much of the emission. Therefore, as a responsible Human being, we have to pay attention to plantation to nullify the effects of Global warming.

Carbon dioxide measurements on the earth’s surface vary from season to season each year. Carbon dioxide emissions peak when it the late spring in the Northern Hemisphere. It declines during the Northern Hemisphere’s spring season. This is because the plants remove some of the carbon dioxide from the atmosphere. What this means are those global warming levels also varying from season to season.

Global warming is also affected by the Earth’s orbiting around the sun, volcanic eruptions, and concentrations of greenhouse gases in atmosphere. There is much debate within the scientific on exactly how much each factor contributes to global warming, but the consensus among scientists is that global warming is largely due to human activity, like journeys travel by travel tourists. This has been made clearest during the past fifty years.

The phenomenon of global first caught the world’s attention with the discovery of the greenhouse effect by Joseph Fourier in 1824. Svante Arrhenius investigated the greenhouse phenomenon quantitatively in 1896. Greenhouse effect refers to the process by which atmospheric gases warms the planet.

Global warming by the greenhouse effect is nothing new. In fact, it is not even disputed. Naturally, occurring greenhouses have been warming the planet out of necessity. Without the greenhouses gases the earth would not be habitable. The debate on global warming actually lies on how much human activity dramatically increases the concentration of greenhouse gases.

Carbon dioxide concentration is currently at 383 parts per million. This level is expected to rise as more fossil fuels (in the form of crude oil and gasoline) are used to fuel human activity. Therefore, it will be in fact a novel idea to plant a tree after your every tour like trip to Morocco.
