Aesthetically, the rhythm and repetition of the image is effective and strong. It shows change and the passage of time, and does provide a feeling of accumulation, or heightening circumstances, with hazardous symbols. The everydayness of the calendar feels real and close-up, and the worsening affect feels critical. It does automatically conjuer ideas about land, however with the green to red spectrum and wildfires parallel to the air quality measured herein. Maybe simple lettering as part of the calendar to label as air? I find the familiarity and the clarity of the image to be very effective in showing scale and progression as well as immediacy and proximity.
