Global Warming and Climate Change: Global warming and climate change refer to an increase in average global temperatures. Natural events and human activities are believed to be contributing to an increase in average global temperatures. This is caused primarily by increases in “greenhouse” gases such as Carbon Dioxide (CO2). A warming planet thus leads to a change in climate which can affect weather in various ways. What are the main indicators of Climate Change? As explained by the US agency

Global Warming Today‚ global warming poses the greatest threat to humanity and our planet earth. Global warming is actually not a new phenomenon by any means. In fact‚ it started alongside with the industrial revolution centuries ago. Nonetheless‚ global warming has taken an ugly turn due to rapid ongoing buildup of human-related greenhouse gases. For example‚ CO2 emissions reached 8.5 billion tons in 2008 and the average temperatures of the earth has risen by as mush as 0.2 degree Celsius

Global Warming So does the earth need us or do we need the earth? Well we know that we need the Earth but how can we help what we need? Global Warming is killing our planet that is essential for our living. So many people have different views on Global Warming. Global Warming refers to an increase in the average temperature of the Earth as a result of the greenhouse effect‚ in which gases in the upper atmosphere trap solar radiation close to the planet ’s surface instead of allowing it to dissipate

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

Since global warming appeared during the last decade as a serious environmental issue‚ it has been the subject of a lot of debate. Global warming is defined as the warming of the earth by greenhouse gases emitted into the atmosphere. But there are many questions about global warming‚ from its causes to its effects. Many people even question whether or not global warming exists. And if global warming does exist‚ people question why it exists. Well‚ there are two different viewpoints. The believers

Global Warming Global warming is the increase of world’s average temperature‚ mainly in the sector of atmosphere‚ seas and the land on Earth. here are three serious factor‚ namely the crack on the lower part of atmosphere‚ pollution on Earth an so many green houses. The first factor is on the atmosphere. Recent years‚ many researches show that atmosphere has some kind of crack because of the heat from sun’s emission. The layer of atmosphere seems can not take the heat anymore. The crack gets larger

OF GLOBAL WARMING Global warming is defined as an increase in the average temperature of the Earth’s atmosphere‚ especially a sustained increase great enough to cause changes in the global climate. The term global warming is synonymous with Enhanced green house effect‚ implying an increase in the amount of green house gases in the earth’s atmosphere‚ leading to entrapment of more and more solar radiations‚ and thus increasing the overall temperature of the earth.

Take a position: Global warming is a real problem. 1000 word Essay. Using persuasive technique Global warming is the increase in the average temperature of Earth’s surface. Since the late 1800’s‚ the global average temperature has increased about 0.7 to 1.4 degrees F (0.4 to 0.8degree C). Climate change is happening and its effects are real. However‚ the larger the change in climate‚ the more negative the consequences will become. Global warming will make life harder for most

Global warming You have probably heard about the phrase “global warming” hundreds of times. But what exactly does global warming means? Global warming is not about having a hot day or week or month in one part of the world. It has to do with the average temperature worldwide. Simply put‚ global warming is the unusual rapid increase in earth’s average temperature worldwide. The warming of the earth began in the mid 1800’s. In the beginning it was small and very slow but then in the 1980’s the
