Poor colour scheme aside, its quite concerning how 2023 is a significant leader in area of forest burned. Sort of shows how the impacts of climate change can compound. Drier weather leads to more fires which reduce the carbon sequestering capacity of the forest which leads to drier weather...
Except that you can't really say that for certain from the map, either—if all the areas that burned over in 2023 also burned over in 1923, I don't think you would be able to tell. There's no method for indicating that the same area was burned over twice in different years.
(Note: I am not saying that 2023 was not the worst fire year on record for Canada. I am picking holes in this presentation of the information because climate change denialists will do exactly the same thing, given half a chance. Let's create better infographics and not give them an opening.)
That statement is based on the article rather than the graph itself.
