Global warming has both natural causes and human causes. However, the results from both are the same: the earth’s temperature is rising. It is rising at an average of 1 degree Fahrenheit per century (green.nationalgeographic.com). National Geographic also outlines that due to global warming, sea levels are rising (news.nationalgeographic.com). Some believe that global warming is not the result of natural problems or human lifestyles but rather that it is a part of a natural cycle (www.cnn.com).

Is this change of temperature based on current levels of emissions or what future levels are estimated to be?
This is a good start to your topic. Will continue by discussing specific natural and human causes?
You mentioned that global warming is caused not only by human causes, but natural causes as well. What would some examples of those natural causes be? I really like the template of your blog. Good choice.
This change in temperature is based on the climate change over the past centuries through data collected and stored and through research in the temperature of air pockets.
Can you explain more about global warming being a natural cycle?
