Global Warming

Introduction

The average increase in temperature of the earth is called global warming. Global warming wasn't an issue before, but nowadays it's a burning issue. For the past 100 years, the temperature of the earth has increased by 0.74 degrees. The reason behind the global warming is green house gases. The greenhouse gases like carbon-dioxide, methane, nitrous oxide, hydro-fluoro-carbons, sulphur hexafluoride and water vapour are covering the earth's atmosphere more than required.

These gases act as a blanket for the heat energy reflecting back to the space and heat the earth's atmosphere more and more resulting in extreme temperature pattern. If the atmosphere is without greenhouse gases, all the energy that comes from the sun radiates back to the space, resulting the earth as a cold ball. However, if the greenhouse effects becomes stronger, more of the heat than needed gets trapped, and the earth becomes less habitable for humans, plants and animals. Different climatic changes like climatic imbalances, draughts, storms, wildfires, hurricanes, rainstorms, sea level increment, extinction of mammals and different typical problems have become the common news nowadays (Americans college of physicians, 2007). Every single day is becoming hotter and hotter, which increases in chance of daily deaths and spreading of diseases.

Discussion

There is great chances of food poisoning and breakdown of infectious and communicable diseases. Developed countries could provide health services to some extent, but the undeveloped and developing countries will have the adverse affect on their health. Developing countries are in more risk of catching health problems as health standard are variable with developed countries. Extreme temperature also results in population displacement in marine life (NASA Home, life on earth). The carbon-dioxide when mixed with water in presence of air changes into carbonic acid changing the chemistry of water in seas and oceans. Mostly northern and southern hemispheres are influenced with extreme temperature(Vensmark 2007).

It results in melting of ice caps and extinction of rear animals like polar bears and snow leopards. Green house gases get emitted from different industrial products and human actions. People are making their life easier by using technological products. China is considered as the main country in the world in manufacturing more technological products in huge amount in cheaper prices. But, these products are the main emitter of greenhouse gases. Currently, China is the leading greenhouse gas emitter country in the world (Howard Steve and Wu Changhua, 2008). Drought and deforestation are happening all over the world. This will push the world into hunger.

Solution

Global warming is a big issue, but it can be overcome. By checking the level of greenhouse gases concentration, the deadly impacts of global warming can be alleviated. The most recent warming is caused by human activity, rather than by geological or astronomical process. The impacts of global warming on human health are starting to hit home and climate change is not going away anytime soon (Americans college of physicians, 2007). China is a leading manufacturer of solar ...
