Climate Files is organized by categories of documents and by keywords assigned to documents. Our Advanced Search page includes a drop-down feature showing all of the categories of documents so that you can more easily narrow your search. The topic field of our Advanced Search page also has a drop-down menu. You can try typing in a word to see if it corresponds with one of the tags assigned to a document. If you try a topic keyword and it doesn’t appear, try to see if a similar term that describes your document does appear.
