Abstract

Estimates of future changes in the characteristics of the air temperature regime in Northern Eurasia over a five-year time interval are presented. The estimates are based on the forecasts of the Earth climate model developed at Marchuk Institute of Numerical Mathematics of the Russian Academy of Sciences. The skill of the forecasts for the territory of Northern Eurasia is discussed using standard skill scores for long-range forecasts. Regions where surface air temperature anomalies are likely to exceed the threshold targets of the Paris Agreement are identified. The consequences of a possible change in the growing season and dates of the stable air temperature above 5°C for agriculture are analyzed. The presented estimates of possible changes in the air temperature characteristics in Northern Eurasia over a five-year interval provide a more objective pattern of expected climate change and can be useful to determine optimal solutions for the development of agricultural sector in the changing climate and to minimize possible negative consequences.
