I think climate change, also called global warming, refers to the rise in average surface temperatures on Earth.Other human activities, such as agriculture and deforestation, also contribute to the proliferation of greenhouse gases that cause climate change.
Give me the importance of your opinion.
glasshouse effect are the biggest cause for global warming.. global warming is one of the sign of climate change
beside that, deforestation (ilegal logging) are the main cause too.. but you know what?? the greatest causes are HUMAN!
