Peter Kuper's April 2023 cartoon presents four panels of road signs altered by climate effects. The upper left panel places a penguin next to a yellow warning sign showing a car plunging from an ice cliff into water. The upper right panel shows lightning, rain and a tornado beside a triangular skid sign. The lower left panel places a red stop sign and a pedestrian crossing sign amid burning trees. The lower right panel shows cars on a highway engulfed in flames with another stop sign and crossing sign.

The cartoon responds to spring 2023 news of record global temperatures, widespread wildfires in Canada and the American West, and continued Antarctic ice shelf losses. Those events followed years of rising emissions data from major oil producers and government reports on extreme weather frequency.

The visual argument equates everyday traffic warnings with planetary-scale hazards. By replacing normal road scenes with fire and flood, the panels suggest that standard safety symbols no longer match current conditions. The progression from ice to storm to fire to burning pavement underscores cumulative effects rather than isolated incidents.

The final panel's highway scene, with vehicles trapped in flames, ties personal transportation directly to the broader crisis. The repeated stop signs function as a blunt call to halt current emission trends. The signature in the corner confirms the artist's identity without altering the message.
