1) What is global warming? (History) Definition: Global warming is the observed century-scale rise in the average temperature of Earth’s climate system. Common sense:Glaciers are melting‚ sea levels are rising‚ cloud forests are drying‚ and wildlife is scrambling to keep pace. It’s becoming clear that humans have caused most of the past century’s warming by releasing heat-trapping gases as we power our modern lives. Called greenhouse gases‚ their levels are higher now than

Global warming Global warming is the increase in the average measured temperature of the Earth ’s near-surface air and oceans since the mid-20th century‚ and its projected continuation. The average global air temperature near the Earth ’s surface increased 0.74 ± 0.18 °C (1.33 ± 0.32 °F) during the 100 years ending in 2005.[1] The Intergovernmental Panel on Climate Change (IPCC) concludes "most of the observed increase in globally averaged temperatures since the mid-twentieth century is very

Global Warming: Cause and Mitigation Your Name Professor Name SCI 110 - Introduction to Physical Science June 12‚ 2013 Global warming‚ also referred to as climate change‚ is real. The question remains‚ is man or Mother Nature responsible for causing it? The Nobel Prize-winning chemist Svante Arrhenius first proposed the idea of global warming in 1896. He knew that carbon dioxide traps heat in the earth’s atmosphere and that burning fossil fuels releases

Global warming is one of the most serious environmental problems that is mainly (concerned by) the government. In terms of addressing this problem‚ biofuels‚ which are a renewable energy produced from crops including corn‚ sugar cane and palm oil‚ are considered as a way to reduce carbon emissions. However‚ biofuels cannot solve this problem effectively due to their limitations which increase greenhouse gases emissions instead of reducing it and also cause deforestation. This essay will outline the

This warming is the result of emissions of carbon dioxide and other greenhouse gases from human activities‚ such as industrial

Probably the most worrying threat to our planet at the present time is global warming. This essay will examine the reasons why global warming is occurring and discuss some possible solutions. The predominant factors resulting in the warming of the earth are the emissions of CO2 and deforestation. CO2‚ which damages the ozone layer‚ comes from several sources‚ but the most problematic are those coming from the burning of fossil fuels from power plants. This releases thousands of tones of CO2 into

He says this will happen from currently frosty areas warming‚ while the amount of “desirable” land will have a tremendous flux. There would be extremely large population drops and inclines all over the world as the climates around the world change for better or worse. Popular places like Arizona and Nevada

Global Warming The greenhouse effect‚ in environmental science‚ is a popular term for the effect that certain variable constituents of the Earth ’s lower atmosphere have on surface temperatures. It has been known since 1896 that Earth has been warmed by a blanket of gasses (This is called the "greenhouse effect."). The gases--water vapor (H2O)‚ carbon dioxide (CO2)‚ and methane (CH4)--keep ground temperatures at a global average of about 15 degrees C (60 degrees F). Without them the average

GLOBAL WARMING : WHAT LIES AHEAD GLOBAL WARMING Climate change is a change in the statistical distribution of weather over periods of time that range from decades to millions of years. In recent usage‚ especially in the context of environment policy‚ it is more generally known as "global warming"‚ which occurs due to increasing levels of greenhouse gases in the atmosphere. Most of the observed temperature increase has been caused by increasing concentrations of greenhouse gases‚ which result

Abstract What is global warming? Global warming is the heating of the earth. Global warming happens when greenhouse gases such as carbon dioxide‚ water vapor‚ nitrous oxide‚ and methane trap heat and light from the sun in the atmosphere. This is known as the greenhouse effect. It prevents heat and light from escaping the earth’s atmosphere kind of like the earth is a giant greenhouse. Global warming is a good thing‚ but at the same time‚ can have devastating effects if not properly monitored and
