Global Warming: Rodriguez Tony P.3
Global warming is caused primarily by carbon dioxide from burning coal, oil and gas.
Certain gases that trap heat are building up in Earth's atmosphere. The primary culprit is carbon dioxide, released from burning coal, oil and natural gas in power plants, cars, factories, etc. (and to a lesser extent when forests are cleared). The second is methane, released from rice paddies, both ends of cows, rotting garbage in landfills, mining operations, and gas pipelines. Third are chlorofluorocarbons (CFCs) and similar chemicals. Nitrous oxide (from fertilizers and other chemicals) is fourth.
Earth's average temperature has risen about 1 degree F in the past 100 years and is projected to rise another 3 to 10 degrees F in the next 100 years.
While Earth's climate has changed naturally throughout time, the current rate of change due to human activity is unprecedented during at least the last 10,000 years. The projected range of temperature rise is wide because it includes a variety of possible future conditions, such as whether or not we control greenhouse gas emissions and different ways the climate system might respond. Temperatures over the US are expected to rise more than over the globe as a whole because land areas closer to the poles are projected to warm faster than those nearer the equator.
Global warming is real and it’s mainly caused by human activities and presents serious challenges. Earth's climate has been warming at a rapid rate since the start of intensive use of coal and oil in the late 1800s. The ozone hole does not cause global warming. Global warming will have significant impacts on people and nature.
As temperatures continue to rise, precipitation is projected to come more frequently in the form of heavy downpours. We can probably expect more extreme wet and dry conditions. Plant and animal species will migrate or disappear in response to changes in climate. While global warming will have impacts on natural and human systems all around the world, the largest

Global Warming Paper Cameron Conolly For years many people have believed that we are causing the Earth to warm up faster. Global Warming is the heating of the climate. Others believe it is due to natural climate processes. Either way, we know that Global Warming is a serious issue for our Earth. One of the reasons we think Global Warming is occurring is because of Orbital Variations. “Orbital Variations” is part of a theory developed by Milutin Milkankovic. An astonishing fact about Milankovic…

Global Warming

Global Warming Jenny Mallory Argosy University Rise of Modern Science Following years of debate publicly on whether global warming is due to natural activities or is the result of mankind, evidence suggests that extreme climate and weather changes are caused by humans. Over the years, the earths’ climate has wavered many times, from periods of record breaking heat to the ice ages. Changes in the sun’s force and the earths’ course around it, along with natural elements such as; erupting volcanos…

Global Warming Essay

GLOBAL WARMING Global warming, also called climate change, has become a topic of concern over the past decade. Climate has changed drastically over the past decade, “From 2001 through Feb, 2011 the atmospheric carbon dioxide increased by 22.2% of the total increase from 1800 to 2001” (Pangburn). Although I wasn’t completely aware of global warming and it’s circumstances until recently, I can honestly say that it is a issue to be concerned about. Global Warming is an indisputable…

Essay on global warming

GLOBAL WARMING: NATURAL OR MAN-MADE There is no question that there is an increase in Earth’s temperature and we are experiencing what is referred to as global warming. The Earth has experienced this many times in history on a much larger scale, but, humans did not exist (and would not have been able to exist) at the time. The questions now are whether human actions are accelerating the process of global warming and possibly decreasing Earth’s future sustainability; and, if so, what, if anything…

Essay on Global warming

What Are the Causes of Global Warming? What is global warming? According to NASA Earth Observatory, global warming is the unusually rapid increase in Earth’s average surface temperature over the past century primarily due to the greenhouse gases released as people burn fossil fuels. Global warming is the warming near the earth's surface that results when the earth's atmosphere traps the sun's heat. The earth is getting warmer. The changes are small, so far, but they are expected to grow and speed…

Persuasive Global Warming

Global warming is the gradual heating of Earth's surface, oceans, and atmosphere. According to the Environmental Protection Agency, “Earth's average temperature has risen by 1.4 degrees Fahrenheit over the past century.” Sadly enough, “temperatures are projected to rise another 2 to 11.5 degrees Fahrenheit over the next 100 years.” As a consequence, global warming has emerged to have one of the biggest environmental issues in the last two decades. For the past years, scientists have been struggling…

Global Warming Essay

endless debate going on about global warming. Some people say that global warming is a threat to us socially, economically, politically, and immediate actions should be taken to minimize it. Whereas, other people say that global warming is beneficial and is a natural process that is required for the sustainability of life on earth. Hence, in my opinion, global warming is a potential threat that causes harm not only to humans, but also to the planet as a whole. Global warming can be defined as the increase…

Global Warming. Is it caused by us? “…Climate change is now with us. It will not go away.”(Musil, 17) Many of us have noticed that our Earth is getting warmer. We seem to ignore what is going on and just continue with our everyday life. There is evidence that our climate has been getting warmer ever year. Some scientist believe it is because of green house gases. Green house gases include the carbon dioxide from gases that our industry produces, methane gases that cows put off, and some believe…
