What are the Pope's scientific qualifications and past experiences with climate change?
The Pope has a significant background that many people may have heard of but may not know the full extent of.  The Pope has chosen to speak on climate change for a reason, and it will be crucial to explain why he is the credible and the right source to do so.  It is also important to show how Pope Francis has created his non-conventional lovable Pope status since taking the position.

Why were the main points in his speeches slightly different from that of his encyclical?
The Pope notably did not directly mention climate change in his speech.  It is important to find out exactly what the Pope said and how he changed his speeches according to the location and the people present.  The information he presented differed from the UN hall to that of the US government.

How will the Pope's and the churches history effect the response to the Pope's call to action? 
The Catholic church has a very controversial background, that cannot be ignored.  Although it is great that the Pope is trying to break down boundaries, there are many issues in his own church that also have to be addressed.  I need to find out how extensive these issues go and determine how they will and have effected the reaction to his speeches and encyclical.
