The Physical Environmental Change

What is global warming? How does it affect the weather, what are the contributing factors? Global warming ***** the gradual process increase in earth temperature; the warming is attributed to the ***** of greenhouse gases in the Earth's upper atmosphere like carbon dioxide and methane em*****sions caused by human activities like farm*****g, industrial and deforestation. These kind ***** discharged smoke that contributes ***** warming of the environment. Many scientists believe that an increase in temperature may lead to ch*****ges in wea*****r patterns that would cause harmful effects like flood, drought and s*****rms. This might also harm the wildlife ***** plants and animals. Animals like birds ***** force to transfer ***** another place. Accord*****g to Time Magazine, "heat waves storms, floods and fires to massive glacial melts, the global climate seem to be crashing around us. Scientists have ********** calling this shot for decades. This is precisely what they have been warning would happen if we continued pumping greenhouse gases into the atmosphere, protecting the heat that flows in from ***** sun and rais*****g ***** temperature." ***** is serious problem ***** real threat to the planet and this is happening more quickly in some parts of ***** world than others. Different regions ***** likely to experience some adverse effects of climate. For example ***** China global ***** has a major effect on agriculture because of temperature ***** because ***** ***** change Africa's supply of foods and water is endangered, even in the deserts of Arabia where summer temperature top 50 centigrade, snow fell.

There are many ***** factors on these geographical changes. These ***** gases ***** the atmosphere; the populati***** growth; burning fossil of fuels and electric power *****. Rising in temperature are expected to increase sea levels like in Arctic Ocean. Researchers have suspected ***** loss of Arctic sea ice may be causes ***** changing atmospheric ***** over ***** Arctic temperatures that result from greenhouse gas build up in the atmosphere (Recent Warming of ***** may affect worldwide climate Oc**********r 2003). The greenhouse helps to balance the global temperature by shielding the heat that surrounds ***** planet, this is very essential for life on Earth. It is the result of heat absorption by certain ***** in ***** atmosphere. Without natural greenhouse effect the temperature of the Earth would be about zero degrees, it has a small contribution to ***** atmosphere but it has big impact and mankind abuse the natural process by creating ***** greenhouse ********** in the *****. Because of ***** increasing greenhouse gas emission it poses negative consequences. According to National Resources Defense Council Arctic region is getting thinner ***** melting. This once permanent ***** is already affecting native people and wildlife and plants. Polar bears, whales, walrus and seals ***** changing their feeding and migration patterns, making ***** native people to hunt them. Along arctic coastlines, entire villages will be uprooted they are in danger of being swamped. ***** native lives in Arctic view ***** warming as threat ***** their culture
