Human Activities Do Have Effects to Global Warming

Introduction

Global warming refers to an increase in temperature in the troposphere, which then causes of climate change. Natural changes, human activities, or both can lead to such warming. Global climate change is a broader word which refers to changes in the Earth's climate, including temperature, precipitation and storm intensity and models.

Most of the world's climate experts say global warming is occurring, that human activity is a key element in raising the temperature, and that human activity is ultimately an increase in warming during this century. However, the difficulty for these scientists to understand climate change is extremely difficult due to lack of technology, and experimentation. In turn, that separates these two groups of scientists.

Earth's climate is strongly dependent on the sun. Without solar energy, the Earth would cool the planet that will not be able to support any life. The greenhouse effect is a natural process that also affects the Earth's climate. The greenhouse effect warms the lower troposphere and the Earth's surface due to the existence of gases called greenhouse gases. These gases are water vapor, nitrous oxide, methane, most know, carbon dioxide. Oceans are the main source, which cover most of the planet, affect climate by storing carbon dioxide and heat, evaporate and receiving water as part of the hydrological cycle, and the transfer of heat through currents (Melvin, 1992).

Causes of Global Warming

Climatic indicators: changes in sea level (blue), the concentration of 18 O in seawater CO2 concentration in Antarctic ice, divide the timeline - 20 000 years. The peaks in sea level, the concentration of CO 2 and 18 O minima coincide with interglacial temperature maxima (Nigel, 1996).

Discussion

Industrial pollution that produce greenhouse gases should be prevented or reduced by ...
