Global Warming

Global warming is the continuing rise in global average temperature specifically the temperature of the atmosphere and oceans. There are some hypotheses that the temperature has risen since the late 1900s century due to the human activity, mainly by emissions of carbon dioxide increased the greenhouse effect.

The greenhouse effect is a natural process that traps some of the sun rays in the atmosphere to regulate the temperature of the earth. This happens when the rays enters in the atmosphere. There are some of the solar rays that was trapped by the greenhouse gases in the atmosphere naturally, and the rest goes to space.

When there is too many gas, more rays are trapped in the atmosphere, and; therefore, the earth warms and the temperature goes up. This is the phenomenon of global warming. Moreover, the global warming associated with climate change that may have one anthropogenic cause or probably not.

The main effect that causes global warming is the greenhouse effect as I said before, which is a phenomenon referred to absorption by certain atmospheric gases— mainly H2O, followed by CO2 and O3— part of the energy that the ground emits, as a consequence of having been heated by solar radiation.

The natural greenhouse effect that stabilizes the climate of the earth is not a question of inclusion in the debate on global warming. That is without this natural greenhouse effect temperatures would fall by about 30° Celsius, and with such change the oceans would freeze and life as we know it would be impossible to have because of the global warming.

The evidence of warming of the climate system manifests itself in observed increases in temperature on earth and into the ocean, widespread melting of snow and ice, and rising...

...we get low the thermostat 2 degrees in the winter and up 2 degrees in the summer, we can save about 900 kilos of carbon dioxide a year.

Moreover, plant a tree. A single tree can absorb one ton of carbon dioxide over its lifetime. In addition, we must turn off electronic devices that we are not using, like the TV, DVD, stereo and the PC. If we do that, we can save thousands of kilos of carbon dioxide a year.

In conclusion, global warming is affecting the planet, and we must start doing something to stop it. I choose this topic because I am worrying about how everything in the world is getting worst. Also, all the changes in the climate and the weather are happening because of the global warming. Everyone must start thinking about this issue and also to contribute by doing all the tips that I mentioned above about how we can stop the global warming.
