1 Climate Impacts of the 1982 El Chichon and 1991 Mt. Pinatubo Eruptions Joseph Carolan and Gregory Deboe Meteo 470: Climate Dynamics Fall 2014 December 15, 2014 Introduction: The changing climate has become a very important amongst the science and political communities over the past 30 years. The Intergovernmental Panel on Climate Change (IPCC) released its First Assessment Report in 1990 as a means of taking a global initiative to study the changing climate and how to respond to these changes.

Animal Migration due to Climate Change In result of climate change, the increased heat, melting ice, shifting precipitation, lack of fresh water and food are causing animals to find more livable conditions. Animals migrate for many reasons, some of them being, to find food, a new home, or to breed. As it becomes warmer the biological cycles of many animals shift, such as, frogs, butterflies, birds and other amphibians. As each decade passes, animals will start to breed earlier and earlier than they

The carbon dioxide levels in the 20th century have been highest in 650,000 years. Till 1950, the levels rose by 11% and recently the levels have risen by 40%. Arctic ice is melting rapidly. It is estimated that by 2040 the region is to have a completely ice free summer, or even earlier. More than 1 million species have become extinct due to disappearing habitats caused due to global warming. Sea levels have risen about 7 inches in the last 100 years, which is more than the previous 2000 years combined

energy applications made it necessary to begin producing it in large quantities. Chlorofluorocarbons (CFCs) were used in appliances such as refrigerants, air conditioning units, and freezers. They since been banned because of their contribution to ozone depletion. HOW IT’S USED TODAY Fluorine is not used in the funeral service industry. Although, fluorine and its compounds (mainly uranium hexafluoride) are used in processing nuclear fuel. Fluorochemicals, including high temperature plastics (i.e. Teflon)

Air Pollution…A Society’s Responsibility The purpose of this paper is to find the correlation between air pollution and society’s responsibility to promote a cleaner safer environment for its citizens. My research question is: How can society help keep the air we breathe safe? There are so many chemicals and other vapors that are emitted into the air that it becomes a chore for people with respiratory problems, i.e., asthma, to breathe without some assistance and in some cases of older individuals

Volcanoes are the eruption of magma, a mixture of rock, crystal, and dissolved gas, expelled through the earth’s crust onto the surface of the earth. Volcanoes consist of the following; a deep magma chamber where magma accumulates, pipes that lead to surface vents, and the vents through which lava is emitted during a volcanic eruption. They occur at three main settings, namely; along subduction zones, a mid-oceanic spreading centres, and above mantle plumes. Environmental effects are determined by

"Study the physiological Effects of Active Oxygen On the Muscle Stress and Blood Enzymes of some Football players" - Introduction and problem of research: Athletes continuously aim to find ways to increase their level of performance to the extent that commensurate with their individual abilities in order to achieve the required sports achievements and access to the advanced centers at all levels, so the sport is witnessing a scientific race in access to means of achieving the desired development

industries and vehicles. The smoke emitted by the factories and vehicles contain nitrogen dioxide and excess of carbon dioxide. Other gases include Sulphur dioxide and lead dioxide. When these gases released into the atmosphere. They result in depletion of ozone layer among other calamities. This layer of three oxygen atoms is key in trapping harmful sun rays that cause diseases such as skin cancer. Moreover, when then the carbon dioxide increases in the atmosphere it forms a

Even if all countries in the world contribute to the air pollution, the developed countries take the leading role on releasing carbon monoxide in the air. This toxic air increases risk of the ozone layer depletion, which potentially would expose UVB radiation at the earth. This UVB radiation has negative consequences on humans, animals, plants and other planetary creatures. In addition to UVB radiation the polluted air by itself can cause serious health

Global warming is the increase in the earth’s atmospheric temperature. Naturally occurring gases such as carbon dioxide, methane, nitrous oxide, ozone and water vapor trap heat from the sun, preventing it from leaving the atmosphere. These naturally occurring gases along with human made hydro fluorocarbons (HFCs), per fluorocarbons (PFCs), and sulfur hexafluoride (SF6) are collectively known as greenhouse gases. This essay will explain why global warming is fast becoming a cause for concern and why
