The causes of global warming are broadly divided into two categories - natural causes and anthropogenic (man-made) causes. Natural Causes Natural causes of global warming include the release of methane gas from arctic tundra and wetlands‚ climate change‚ volcanoes etc. Methane‚ a greenhouse gas which traps the heat within the earth’s atmosphere‚ is let out in large quantities in the arctic tundra and wetlands. In case of volcanoes‚ when a volcano erupts‚ tons of ash is let out into the atmosphere

Global warming is the term used to describe a gradual increase in the average temperature of the Earth’s atmosphere and its oceans‚ a change that is believed to be permanently changing the Earth’s climate. Even though it is an ongoing debate‚ it is proved by the scientists that the planet is warming. The 29th century is experiencing a continued increase of Earth’s mean atmospheric temperature by about 1.4 degrees F and about two thirds of it occurring since 1980. This is global warming is affecting

While Al Gore’s multi-million grossing and revolutionary documentary An Inconvenient Truth seemed have to strongly entrenched pre-existing beliefs about the massive role of humans in global warming‚ the movie I saw just a couple of days later in LCH seemed to challenge all of them. Was almost everything we’d been hearing about our in global

This is the question that has been the ground for major debate for many years‚ is our advancements causing global warming? When debating global warming the first thing to consider is what the cause of global warming is‚ and the answer to this basic question is greenhouse

paper products‚ also cut countless trees each year. Loggers‚ some of them acting illegally‚ also build roads to access more and more remote forests. This process just leads to further deforestation. Forests are also cut as a result of growing urban populations. Hydroelectric dams are quite controversial because while they help to power communities‚ they also contribute to deforestation. Damming opponents believe that the building of such structures not only has a negative environmental impact‚ but it

In the controversy over whether Global Warming there is two sides in which people can choose either human caused or just Mother Nature doing her thing. Most scientists will tell you that Global Warming is mostly the cause of humans. While there are some who will disagree and say that it is just nature doing what it has done for thousands of years. For most scientists the topic of global warming is one that is caused by us humans. They have many facts data to back this up. Some examples of these

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. Global surface temperature increased 0.74 ± 0.18 °C (1.33 ± 0.32 °F) during the 100 years ending in 2005.[1][2] The Intergovernmental Panel on Climate Change (IPCC) concludes "most of the observed increase in globally averaged temperatures since the mid-twentieth century is very likely due to the observed increase in anthropogenic

The issue of global warming has become a hot topic in not only in American‚ but all over the world. For years‚ many politicians have evaded the issue of global warming. But now‚ all of a sudden‚ the Democratic Party vows to combat global warming. Now that the Democratic Party has majority in both houses on Congress‚ they have taken an emphasis over environmental issues‚ mostly involving global warming. On January 30th‚ 2007‚ Congress held its first hearing about global warming. What was concluded

Even though climate change is partially caused by the natural cycles of Earth‚ humans are still a major part of it. Greenhouse gases‚ such as carbon dioxide‚ absorb and emit heat in the atmosphere‚ keeping Earth warm enough to support life. However‚ human activities‚ such as burning fossil fuels‚ are adding large amounts of greenhouse gases to the atmosphere. Earth must get rid of energy at the same rate it receives energy. More greenhouse gases mean that more heat is being held in the atmosphere
