Modified atmosphere

The atmosphere is a clear odourless gas that envelopes the Earth, held together by gravity. Everyone on the planet has the right and access to the atmosphere, making it a global common. There are many components that make up the atmosphere, the main components is nitrogen, which makes up 78.09% of the atmosphere, and oxygen, which makes up 20.95%. Around 1% of the atmosphere is comprised of water vapour, methane, carbon dioxide, sulphur, argon and particulates (e.g. dust). There are a total of…

Until recently it was believed that the earth had only experienced 4 to 5 glacial periods, all of which occurred in the past 2 million years. (Louis Agassiz, 1837) However, globally conducted research has revealed that countless glacial advances have appeared over 200 million years ago, thus broadening our insight of the history of the earth system by 100 times. These astonishing advances have witnessed the introduction of a new sub-discipline—palaeoclimatology, which specialises in the study of…

Global climate change is modifying the population of microorganisms and the distribution of their species. Microorganisms live in environments where more than type of species exist. Each species of microorganism plays a major, minor or no role in intricate groups. There is variation amongst microorganism and because of this all species of microorganisms will not react to global climate change in the same way. These microorganisms have a vital role in ensuring components such as carbon and…

EVIDENCE OF GLOBAL WARMING Only a person who has been away from our planet for some time would claim that global warming is not happening. The evidence shows abundantly on all the continents of the world. Several aspects of climate have been affected. For instance, in the temperate zones, the summers are warmer and more humid. Droughts are more frequent, particularly in Africa. Rainfall and snowfall are more intense and, in some cases, quite destructive. Snow (or ice) cover on mountaintops is…

more of a problem. Global warming, as a result of these human activities, can have many large-scale consequences. The earth 's atmosphere is constituted to allow sunlight to stream in uninterrupted. After striking the earth 's surface, this solar energy is reflected as longer wavelength infrared radiation. Some of this radiation is subsequently trapped in the atmosphere by clouds…

In four-hundred and sixty million years ago in the Ordovician era the plates are moving again and a new continent is formed called godiwalla. There should be plants and animals now because of the oxygen level, but there is only one reason why there isn’t any life on land yet, the sun. The sun is blasting the earth with deadly radiation, life on earth would not survive at all. With thirty miles from the earth 's surface the oxygen meets the sun 's radiation it forms another gas called the ozone.…

Have you ever wonder why there’s no running waters on Mars? Many of us might be questioning why we can’t survive on Mars; well, the main reason is there’s lack of air, oxygen, and importantly water. There are resources clarifying that there are water on Mars; however, the water are all frozen into ice. Scientist are discovering the reason that causes the water to turn into frozen ice. The article “Climate cycles may explain how running water carved Mars' surface features” written by Matthew…

many factories have been built emitting carbon (Harvey 1) , but most of all the burning of fossil fuels has emitted an enormous amount of carbon-ten million metric tons(Bringham 25) in the atmosphere! Every car, train, plane, house heating system uses fossil fuels for energy but also emits carbon in the atmosphere. At…

Both of the given reading assignments written in joint efforts with a myriad of researchers and our upcoming speaker Dr. Kessler took an in depth look at the Deepwater Horizon Oil spill. The first report published in Science magazine focused on the effect of the methane (CH4) release. In contrast to the earlier published article the second, published in Environmental Science magazine amassed data on the spread of the CH4 plumes. While in ordinary conditions CH4 in the ocean is no cause for alarm…

Wind Energy-The Power of the FUTURE How does wind energy work? When the sun warms the land on the Earth, the atmosphere heats also. Warm air rises and cool air sinks, therefore, when the warm air rises, the cool air from the sea replaces it. This movement of air is what makes the wind blow. When the wind blows against the wind turbines, this spins the blades. These blades capture some of the kinetic energy from the wind. The generator takes the kinetic energy from the spinning blades and turns…
