Earth to sustain life is known as the "greenhouse effect." However‚ vital this effect is for human life‚ it may also be what eventually causes the next ice age‚ bringing all life to an end. About half of all solar radiation reaches the earth’s surface. The other half‚ is either returned back in the form of heat‚ or is used for such things as photosynthesis‚ changed to heat energy‚ then sent back into the atmosphere. Gases such as carbon dioxide hold onto heat‚ in turn‚ warming the earth’s surface. Without

Global warming is caused by air pollution Global warming has been around our Earth for centuries‚ but recently has become a bigger problem for our environment. There has been debate whether or not global warming is a natural occurrence for our planet‚ and doesn’t really exist. While others argue that human activities is causing global warming. Global warming is caused by many things such as pollution that is damaging our environment. The causes are split up into two groups. There are the natural

Topic: Climate Change Question: What are the factors that affect climate change? Causes of climate change The earth’s climate is dynamic and always changing through a natural cycle. What the world is more worried about is that the changes that are occurring today have been speeded up because of man’s activities. These changes are being studied by scientists all over the world who are finding evidence from tree rings‚ pollen samples‚ ice cores‚ and sea sediments. The causes of climate change can be

In the documentary film Earth Story: The Big Freeze‚ they stated that geologist before discovered that some parts of the northern hemisphere were covered in gigantic ice sheets. Scientists learned that waxing and waning of these ice sheets are the products of the warming and cooling of our climate millions of years ago. And

Climate change has a wide range of adverse effects on the natural world and manmade systems. The main concerns are the risks posed on the Earths geophysical and ecological processes. Many causes influence climate change with the main cause being increased atmospheric greenhouse gases. Other major causes include deforestation‚ land-use changes‚ and chlorofluorcarbons

Climate Change Essay I claim that human activities‚ like emitting greenhouse gases‚ are causing global warming. Some scientists have decided that we‚ through the greenhouse effect‚ are causing global warming by burning oil‚ gas‚ and coal. The greenhouse effect helps to keep the Earth hot enough that it can sustain human life. Sunlight come down through the atmosphere‚ and then clouds reflect some of it off and back into space. Most of it is used to warm the planet. When the ground is warmed‚ the

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
