Global Warming
When we talk bout global warming, we are actually talking about having too much of something that naturally occurs. Water vapor, carbon dioxide, and other gases trap some of the outgoing energy from Earth and in turn retain the heat. This is almost the same as a greenhouse. The same way a greenhouse makes the temperature comfortable enough for plants to grow the natural greenhouse makes it a hospitable 60 degrees Fahrenheit on Earth. The problem is that people have been creating more greenhouse gases since the Industrial Revolution than at any other time in Earths history. This is thought to have already caused the loss of many of Earth's ice glaciers. If we continue at the same pace carbon dioxide concentrations are predicted to be 30 to 150 percent higher than today, by year 2100. If governments are successful at putting in policies that reduce emissions we might be able limit the effect of too much greenhouse gas.
