The report based on the work of some 2,500 scientists in more than 130 countries concluded that humans have caused all or most of the planetary warming. Human-caused global warming is often called "anthropogenic climate change".
*Industrialization, deforestation, and pollution have greatly increased atmospheric concentrations of water vapor, carbon dioxide, methane, and nitrous oxide, all greenhouse gases that help trap heat near Earth's surface.
*Humans are pouring carbon dioxide into the atmosphere much faster than plants and oceans can absorb it.
*Some experts point out that natural cycles in Earth's orbit can alter the planet's exposure to sunlight, which may explain the current trend. Earth has indeed experienced warming and cooling cycles roughly every hundred thousand years due to these orbital shifts, but such changes have occurred over the span of several centuries. Today's changes have taken place over the past hundred years or less.
SO WOULD YOU CONSIDER YOURSELVES ALSO A FACTOR CONTRIBUTING TO GLOBAL WARMING??? I would be glad to hear your opinion guys!!! ^_^

We all contribute to global warming. What we can is to slow down the possible effects of this by lessening emission of greenhouse gases and planting more trees.
i recently watch a documentary her in our country that the effect of climate change is very alarming. some parts of the land have been submerged in salt water.
lets do our part in protecting our planet.

yah right ceasar! we should start within ourselves to value nature and protect it by doing interventions like as what you've said planting trees, another is to minimize or if possible eradicate pollution, conserve water, waste segregation, keeping the environment clean and most importantly do a campaign to reach out other people and educate them the importance of helping one another to save earth. It would be of great help and I know we can do it! So let's start not tomorrow but today, right now!!!
