Two scales were used in the work: IPCC Interest and scientific interest. In order to examine the scientific interest of the phenomena examined, I used Google scholar and checked the number of articles published between 2003-2013 which are about ten years prior to the departure of the report of the IPCC which is the source of the scale to which I compared the results. In addition, in order to obtain more reliable and accurate results, the search is done in articles that are written in the English and include in their titles the names of the phenomena examined.
The second scale I used is the IPCC interest. In order to find the interest of the IPCC in the phenomena examined, I used the last report of the IPCC which consists of three parts (they can be listed). In each part, I checked the number of times the phenomenon appears in the report by using Cntl + F searching. 
In the table below, you can see the keywords used and the number of articles found on Google scholar and the number of mentions of the phenomena in different parts of the  IPCC report:
