Global warming

Global warming as one significant environmental issue catches more and more eyes from all over the world with the overwhelming effects.   The Earth is heating up, and how the warming effects on Earth may affect crops and climatic conditions. Several current trends clearly demonstrate that global warming is directly impacting on; rising sea levels, the melting of icecaps, and significant worldwide climatic changes. In my understanding, global warming represents a fundamental threat to all living things on earth.

Any object in universe has electromagnetic radiation. Objects’ temperature get higher, the wavelength of radiation get shorter. When the electromagnetic radiation cross the atmospheric and down the ground there part will inverse radiation. The ground will be getting warmer and warmer. That means the atmospheric keep the ground warm. This is the principle of atmospheric greenhouse effect.

Atmospheric greenhouse effect brings global warming issues.
Global warming stems directly from the human's nearly barbarous activities. the most important point is the Increasing human population numbers which are putting great pressure on many of these limited resources and make almost use of these energy resources, no doubt that human activities are altering the equilibrium involved in these natural processes and cycles. What’s more, the pressure of the growing population also makes changes of the use of energy that acreats the emission of carbon dioxide. Finally, with the development of technologies, the atmosphere like the ozonosphere is becoming thinner day by day.

Fossil fuels, industry, and agricultural processes caused by human, natural, and other gas emissions. This results in an increased emission of greenhouse gases. Short-wave solar radiation sinks into the Earth's atmosphere and warms its surface; while long wave infrared radiation emitted by earth's surface is absorbed, and then re-emitted by trace gases.

Nowadays, some parts of...
