many scientific researches, conducted on climate change have resulted that sudden climatic changes are the cause of global warming in the environment. The term ‘Global Warming’ is defined as the gradual increase in the temperature of the earth’s atmosphere due to the greenhouse effects which results in the corresponding changes in the climate. According to IPCC’s research, Earth’s global temperature is increasing by 1.4 degrees F since 1880. As a result of global warming, there has been occurring

Many people including environmentalist, study this topic to determine the seriousness and world impact. The typical understanding of this concept “global warming” is known to be the total long-term intensification in the temperature present in the atmosphere (3). When discussing this topic, it is still important to consider the fact if Global Warming is actually fact or fiction. In order to evaluate this controversial issue, one would need to discuss evidence for or against the idea of global warming

efficiently”. The food planted needs to have enough nutrients in its roots to be able to grow and have enough nutrients for humans to survive. For human survival, we would have to plant enough plants for some to be used as creating oxygen in the atmosphere and the edible portion to our nutrition. This would keep us healthy on Mars and be able to survive. Surprisingly enough, the Martian soil contains nutrients that is even more nourished than some of Earth’s soils. This means that the soil doesn’t

Much like the glass of a greenhouse, gases in our atmosphere sustain life on Earth by trapping the sun 's heat. The Earth’s atmosphere contains several different gases that act like a blanket, keeping the Earth warm. Water vapour and some trace gases like CO2, CH4 (methane), O3 (ozone), N2O (nitrous oxide), are “IR active”, i.e. they absorb heat energy, and stop the warmth from escaping into space. Without the entrapment of heat, the earth’s mean temperature would be -180 C and life, as we know it

the earth warmer, there is way more to it in the effects of global warming than just heat. Global warming is the increment in the average temperature of Earth's atmosphere and oceans, which is observed and projected during long-time scale. And it brings with it many negative effects such as; the increase in the temperature of the atmosphere, the melting of the ice caps, the loss of species, the increase of storms, diseases, and economic consequences. The factors that cause global warming are divided

change affected the atmosphere, temperature, and water cycles. Research shows that planet Earth is in fact still warming. Senator Al Gore says this about global warming: “You see that pale, blue dot? That’s us. Everything that has ever happened in all of human

the increase in greenhouse gases in the atmosphere induced by human activities. On the other hand, the scientists believe that there are natural causes of global climate change. While the supporters of the man-made theory of global climate change reason that the major greenhouse gas causing global warming is carbon dioxide, the advocates of natural causes

fact. Certain gases in the atmosphere, such as carbon dioxide, trap and absorb the sun’s energy and re-radiate that thermal radiation in all directions, which causes the Earth’s surface to warm. This is known as the greenhouse effect, which is another undeniable fact. The greenhouse effect is not a new concept, however the media portrays its influence to be entirely harmful on the climate. Most people fail to realize that if greenhouse gases were absent in the atmosphere, the average global temperature

4 Research Methodology In last months, my centre of attention was on understanding the qualification of atmosphere factors perturbation in sound speed and comparing different acoustic tomography methods. Then, these techniques have been applied to series of synthetic and obtained data from field trials. This part contains tasks and activities will be provided with the aim of the PhD project as follows: • Estimate variations impact on tomography process • Develop tomographic method with acoustic variations
