 Located just beneath our search-volume graph is our news-reference-volume graph. This graph shows you the number of times your topic appeared in Google News stories. When Google Trends detects a spike in the volume of news stories for a particular term; it labels the graph and displays the headline of an automatically selected Google News story written near the time of that spike. Currently, only English-language headlines are displayed, but we hope to support non-English headlines in the future. Below the search and news volume graphs, Google Trends displays the top cities, regions, and languages for the first term you entered."

Second, "as a Google Labs product, it is still in the early stages of development," meaning it is prone to error because "several approximations are used when computing your results," but Google does not say what these are.
