Environmental Changes The Physical Environmental Change What is global warming? How does it affect the weather, what are the contributing factors? Global warming is the gradual process increase in earth temperature; the warming is attributed to the increase of greenhouse gases in the Earth's upper atmosphere like carbon dioxide and methane emissions caused by human activities like farming, industrial and deforestation. These kind activities discharged smoke that contributes to warming of the environment.

Many scientists believe that an increase in temperature may lead to changes in weather patterns that would cause harmful effects like flood, drought and storms. This might also harm the wildlife like plants and animals. Animals like birds may force to transfer to another place. According to Time Magazine, "heat waves storms, floods and fires to massive glacial melts, the global climate seem to be crashing around us. Scientists have been 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 the sun and raising global temperature." This is serious problem and real threat to the planet and this is happening more quickly in some parts of the world than others. Different regions are likely to experience some adverse effects of climate.

For example in China global warming has a major effect on agriculture because of temperature and because of climate 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 contributing factors on these geographical changes. These are gases in the atmosphere; the population growth; burning fossil of fuels and electric power plants. Rising in temperature are expected to increase sea levels like in Arctic Ocean.

Researchers have suspected that loss of Arctic sea ice may be causes by changing atmospheric patterns over the Arctic temperatures that result from greenhouse gas build up in the atmosphere (Recent Warming of Arctic may affect worldwide climate October 2003). The greenhouse helps to balance the global temperature by shielding the heat that surrounds the planet, this is very essential for life on Earth. It is the result of heat absorption by certain gases in the atmosphere.

Without natural greenhouse effect the temperature of the Earth would be about zero degrees, it has a small contribution to the atmosphere but it has big impact and mankind abuse the natural process by creating more greenhouse gases in the atmosphere. Because of the increasing greenhouse gas emission it poses negative consequences. According to National Resources Defense Council Arctic region is getting thinner and melting. This once permanent ice is already affecting native people and wildlife and plants.

Polar bears, whales, walrus and seals are changing their feeding and migration patterns, making for native people to hunt them. Along arctic coastlines, entire villages will be uprooted they are in danger of being swamped. The native lives in Arctic view global warming as threat to their culture identity and survival. Population growth and climate change can be linked, the size of the population can be a contributing factors.

The growing population has a great impact on the extent of global warming and its consequences for society, economy and the environment. This means that there is rising in greenhouse emission, more people means more industry. Scientists worry about the emission from developing countries which may contribute to global environment problems even sooner than expected. But not only the developing countries contributes to the emission but also rich industrialized countries have been putting carbon dioxide and other greenhouse gases in the atmosphere for many years now.

"20% of the world's population can not continue to indiscriminately pollute the atmosphere at the expense of the majority" (M. Glantz 2005). Rich industrialized countries contributes a higher percentage of emission at the atmosphere that increases the environment's temperature of global warming and results to change of weather pattern to different regions. "Africa's contribution to the increasing concentrations of greenhouse gases has been minimal, yet according to the IPCC, Africa is the most vulnerable continent to climate change as widespread poverty severely limits its capabilities to adapt" (Glantz 2005).

This only explains that in comparison Africans are poor and have a very few resources to support their basic needs like food and water, these people are more affected by climate change and can not cope up with this global warming problem. The global warming is a world's issue that being debated for several years now and needs to be resolved. The Earth's ability to provide food and energy is finite and requires the help of the world's people, industrial leaders and environment experts.

According to Norwegian Prime Gro Harlem Brutland, "The world is warming up, and we know that the issue is to be able to act quickly enough to avoid dramatic consequences that are also irreversible without.
