          "Contemporary climate change includes both the global warming caused by humans, "
          "and its impacts on Earth's weather patterns. There have been previous periods of climate change, "
          "but the current changes are more rapid than any known events in Earth's history. "
          "The main cause is the emission of greenhouse gases, mostly carbon dioxide (CO2) and methane. "
          "Burning fossil fuels for energy use creates most of these emissions. "
          "Agriculture, steel making, cement production, and forest loss are additional sources. "
          "Temperature rise is also affected by climate feedbacks such as the loss of sunlight-reflecting snow cover, "
          "and the release of carbon dioxide from drought-stricken forests. "
          "Collectively, these amplify global warming."
