【 摘 要 】

Natural variability plays a large role in local climate that makes it difficult to detect the local signal of global climate change even on a multi-decadal timescale. Due to this reason, searching for climate indices that are less sensitive to natural variability and more sensitive to global climate change is an important scientific activity. Here, we show that the observed changes in Moscow's continentality index - four percent decrease per degree increase in mean annual temperature - are in line with climate model simulations, and hence they could be attributed to the global climate change, at least in principal.
