Fact ( in question form): Is the atmosphere vulnerable
1st source: http://www.ul.ie/~childsp/CinA/Issue59/TOC4_Atmosphere.htm. The author of this source is Bill Byers. The credentials of this source is the School of Applied Biological and Chemical Sciences, the University of Ulster at Jordanstown, Newtownabbey, and Co. Antrim BT.There is one quote and it is "The optimist proclaims that we live in the best of all possible worlds; and the pessimist fears that this is true." - James Branch Cabell. This source is credible because of one thing and that is the title of the article in the source. The title is Our Vulnerable Atmosphere. To me, the title explains what I am looking for. The Source says that our atmosphere is vulnerable because the tile explains it. I believe the source because it is written by someone from a university. Also he teaches science at the university.
2nd source: http://www.ucar.edu/communications/ucar40/atmosphere.html. The author of this source is Jacque Marshall. There are no credentials for this source. This source is credible because it has the the necessary things a source needs to have to be called trustworthy. One reason I know this is because the author left is email address right next to his name at the bottom of the article. This source says that the atmosphere is vulnerable. I believe the source because it is credible in ways like one I mentioned above.
3rd source: http://www.climate.org/topics/climate-change/tickell-lecture-vulnerable-earth.html. The author of this source is Crispin Tickell. This source has no credentials. This source is credible because this is the article that was typed up from Crispus Tickell's lecture in Washington D.C.. The source says that the atmosphere is vulnerable. I believe the source because this article is on the website Climate Institute, so I know that I can trust this source because it focuses on the Earths climate and obviously the institute is looking in and has been looking in to Climate Change or Global Warming.
After reading my three sources, I have determined that my fact " Is the atmosphere vulnerable?" is true. I believe it.
