The evidence that declines of snow and ice, other than of Arctic sea ice extent, are not consistent with reasonably expected natural variability does not rely on computer simulations alone. Detection of declining snow and ice is based on observations. Both observations and models are used to estimate natural variability in the climate system, and attribute the most likely cause for the detected declines.
