Abstract Trends in current global and regional climate change are estimated based on observations and reanalysis data, as well as on the basis of model simulations. Special attention is paid to climate changes in the Arctic and North Eurasian regions. Temperature and sea ice changes in the Arctic and Antarctic are compared. The processes contributing to the enhancement of regional climate variability are considered. The role of natural and anthropogenic factors in climate change and the ability of models to adequately simulate current climate changes are assessed. Possible changes in relative contribution of natural and anthropogenic CO 2 and CH 4 emissions in the North Eurasian regions under global warming are discussed.
