The evidence that present rates of decline in the extent of Arctic sea ice are not consistent with reasonably expected natural variability does not rely on computer simulations alone. Detection of the decline 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 decline.
