Loaded Weather Dice: How Climate Change Reshapes Extreme Heat

Daily temperature has always fluctuated around a seasonal average in a roughly bell-shaped pattern. This simulator renders that distribution as a live 3D bar histogram: adjust global mean warming and a variability (spread) change, and watch the curve shift and widen exactly as observed climate data has since the mid-20th century. Individual simulated days rain down and land in their bin, colored red once they cross an adjustable extreme-heat threshold, and a running tally converges on the exact probability predicted by the normal distribution's tail — the same statistical mechanism climatologists use to explain why once-rare heatwaves are becoming routine.
