Global warming is an increase in the earth's temperature due to fossil fuels, industry, and agricultural processes causes by human. This results in an increased emissions of greenhouse gases. The greenhouse gases are carbon dioxide, methane, and nitrous oxide. These gases occur naturally. The Earth uses those gases to warm its surface. Carbon dioxide is released into the atmosphere when solid waste, fossil fuels, wood, and wood products are burned. Each greenhouse gas absorbs heat differently. If natural gases did not occur, the temperatures would be 91.4 degrees cooler than the current temperatures. These gases trap heat and cause the greenhouse effect, rising global temperatures. Human activities add to the levels of these gases, causing more problem.
