The TERMS CHART is a breakdown the 250 terms projected in the Basemap, and their use, year-by-year, across the 5 industry groups.
The goal of this visualization was to see if there were shifts in words being used to describe climate risk across the 6 years of data (i.e an obvious growth or decline of certain terms), and also to reveal a finer grained analysis of which words were particularly favored by which industry groups. Slide across the different colors on the bars (representing the different industry groups), and you will get a raw occurrence account per industry group per year of the use of this term.
Three things to note: 1) the scale of the “Totals”, is not the same as the individual words year by year. This was a compromise in being economical with our visuals that simply needs to be pointed out; 2) one term, "Weather conditions”, was of such larger size than all the other terms that we simply removed it from the graph because it rendered all our histograms much less visible and harder to interpret; and 3) also within this visualization, you can see a version of the "heatmap" idea implemented year-by-year across the industry groups by clicking on the "maps" button next to the year. This is basically the same idea as described in the Basemap visualization, except that we made annual base maps, so the map changes each year making comparison between years and sectors more difficult
One overarching finding deserves immediately to be pointed out looking at these bar charts of the 5 sectors. Referring to the “Totals" for each year, we clearly see that in terms of ink spilled discussing climate risks, the bulk of the discussion seems to be happening in disclosures related to "Electricity and Coal" and "Oil and Gas”. Over the 6 years of the corpus, 85.51% of the “climate risk” conversation is being lead by these two sectors ([62,018 term occurrences “Electricity and Coal” + 70780 term occurrences “Oil and Gas”]/ 155,286 overall term occurrences). There is very little penetration, in other words, of these issues in the other three sectors, despite the fact that they all face "material" consequences from a changing climate.
Afterward, there is a great deal to explore regarding the question of shared vocabularies of "climate risk”, which we invite you to do.
