Global warming is leading the world into a point of no return. Humans have been modifying the environment exponentially‚ and since the industrial revolution the “carbon dioxide in the atmosphere has increased by about 35%” (Le Treut 97). Who is the responsible of these changes‚ how do we know they are true‚ and how does these changes would impact our living in the future? This carbon dioxide increase is known to be mainly caused by the deforestation of forests‚ and the combustion of fossil fuels

15 Dec 2011 Global Warming/Climate Change Before we get into the specifics‚ lets define the terms global warming and climate change. Global warming or the greenhouse effect is a more specific term that refers to a gradual increase in planet-wide temperatures which is now well documented and accepted by scientists as fact. It is the warming of the lower atmosphere which is a result of the increase of a number of gases that have been classified as greenhouse gases. It is a specific type of climate

Global Warming [Client’s Name Appears Here] [Client’s College/University Appears Here] Date Global warming is a threat to earth and mankind. Global warming refers to the increase in the temperature of earth’s atmosphere. The increase in global temperature has been occurring in the past several years. According to Nardo et al.‚ author of Climate Crisis: The Science of Global Warming‚ “scientists noted that of the 21 hottest years recorded‚ 20 of which occurred

Websites researched were NASA‚ ICUN‚ National Geographic‚ BBC News‚ The Independent‚ IPCC‚ Arctic Council‚ National Resources Defense Council‚ UN News and D.V.D. called ‘An Inconvenient‚’ truth. Evidence researched supports the conclusion that scientists believe global temperatures have been rising and that human activity is a significant contributing factor.

October 3‚ 2013 Period 8 Senior Science Global Warming Controversy Humans have known about global warming for many years now. But Al Gore did not discover global warming. Neither did Tim Flannery‚ Peter Garrett‚ Greenpeace or Malcolm Turnbull. However they did add their scientific two cents and made everyone more knowledgeable on what this topic is really about‚ and stressed the importance it has on the Earth. Scientific concern about global warming is not new. This is nothing surprising or

The biggest threat to life on earth comes from global warming. Rich industrialised countries in the West have been burning fossil fuel such as coal‚ oil and gas for about 150 years‚ pumping out vast quantities of carbon dioxide. This gas traps the heat from the sun and causes the Earth and the atmosphere to get warmer. This is called the greenhouse effect. So why global warming is a problem? Well‚ high level of these greenhouse gases in the atmophere causes climate changes‚ which also lead to

Global Warming “The Earth ’s climate has changed throughout history. Just in the last 650‚000 years there have been seven cycles of glacial advance and retreat‚ with the abrupt end of the last ice age about 7‚000 years ago marking the beginning of the modern climate era — and of human civilization. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives.” (NASA.GOV) Going through the history in our planet’s

GLOBAL WARMING Global warming is the ‘talk of the town’ in this century‚ with its detrimental effects already being brought to limelight by the recurring events of massive floods‚ annihilating droughts and ravaging cyclones throughout the globe. The average global temperatures are higher than they have ever been during the past millennium‚ and the levels of CO2 in the atmosphere have crossed all previous records. A scrutiny of the past records of 100 years indicates that India figures in the first

Global Warming Global warming is the most pressing challenge facing the world today. After examining what global warming is‚ I have realized that human activities have a large impact on how the earth’s surface temperature is due to the greenhouse effect. I also have realized the impact that global warming can have on the earth. We as human’s need to do what we can to lower our contributions to the global warming before it is too late. Global warming is the increase of earth’s average

Thesis: Global warming is a human induced phenomenon causing a dramatic rise in average global temperatures and posing a major threat to our planet and it’s ecosystems. Points of Evidence: The science is clear: Human activity is causing our climate to change. -When we extract and burn fossil fuels such as coal or petroleum‚ we cause the release of carbon dioxide (CO2) and other heat-trapping “greenhouse gasses” into the atmosphere. Though natural amounts of CO2 have varied from 180 to 300
