The Wiki article I read was about global warming and the supposed causes and effects of it. Some things that surprised me were that the article remained very neutral on the topic. Staying neutral is a hard thing to do because global warming is a very polarizing topic, but the authors remained neutral by stating the scientific findings of global warming and keeping their opinions out of it. The article had a bunch of different paragraphs, not only discussing what we believe causes global warming but also talking about the effects it has on our environment and humans. However, I did find some inaccuracies in the article. First, the article mentions that we see the hottest temperatures ever recorded in history. However, the hottest era known to scientists was the Neoproterozoic Era. While this was several hundred million years ago, the average temperature of that era was significantly warmer than today's temperature. This leads to the second inaccuracy I found. The Wiki article talked about human's contribution to climate change, and stated a quote from the IPPC that said: "It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century.". However, this quote is very inaccurate is disproved by many scientists, including scientists from NASA. It was discovered that the sun had a bigger impact on earth's increase in temperature. When looking at a "hockey stick curve" (which shows the relationship between rising CO2 emissions and temperatures), it is discovered that the relationship between the two is not nearly as similar as the relationship between solar activity and rising temperatures. Despite these minor inaccuracies, the article covered all the information in a clear and concise way.
