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 is one of the most challenging environmental problems in existence today. Global warming is an increase in the earth’s temperature due to fossil fuels‚ industry‚ and agricultural processes caused by human‚ natural‚ and other gas emissions. It threatens the health of the earth’s inhabitants and the world’s economies every day. With global warming come longer and more intense heat waves and storms. Along with those climate changes‚ come more pests which in turn can carry devastating

Global Warming Have you noticed that our summers have been extremely hot and our winters have been less extreme than in previous years? If so you are noticing what is referred to as global warming. What this refers to is an overall increase in the temperatures around the world. Due to human activities‚ such as pollution and the amount of gas we use‚ and through natural events‚ it had caused the average temperature across the world to rise substantially. In addition‚ the rise of use in gases

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 is the average annual temperature of the earth. This topic has evidence that demonstrates it is a serious concern. This is shown in the affect of global warming on humans‚ wildlife‚ and in the image with the people at the beach. Global warming has a negative affect on humans and wildlife populations. To start‚ global warming has a negative affect on humans because it will begin to take up all of the food and water supplies from crops and gardens. Global warming is an extreme problem

GLOBAL WARMING One of the most strongly debated topics on our earth is the issue of climate change. Global warming and climate change is 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) I. Effect There are two effects of global warming which is the environmental and social changes

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

I. WHAT IS GLOBAL WARMING? Global warming is the gradual increase of the Earth’s average measured temperature overtime. This measured average temperature is derived from both the near-surface air as well as ocean waters. Scientists began measuring this temperature beginning in the mid-20th century and have continued to monitor fluctuations and deviations in measurements ever since. The average global temperature increased approximately 1.33°F over the past 100 years ending in 2005. This led the

Through the eyes of most scientists‚ global warming is seen as a very serious and severe threat. The actions taken by humans‚ such as industry and consumption of fossil fuels plus the increase in population and agriculture have played a big part in global warming. If something is not done soon the results could be very bad. By the middle of the twenty first century‚ there is evidence that the Earth will be warmer than it has been at any time in human history‚ and quite possibly since the

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.
