Year: 2018, Number: 1, Pages: 8-23

Trends of climate change on the islands of Far Eastern seas has been studied by the examples of the Komandorsky, the Kurils and the Poronaysky nature reserves. It was figured out that in recent decades climate warming has taken place in all islands, and it increased in the XXI century. Climate changes have regional particularity, expressed in terms of different intensity of warming on various islands by year and by season. In the Poronaysky and the Kurils reserves warming is the most considerable in winter, and summer warming is specific for the Komandorsky reserve. There are no clear regularities in annual and seasonal distribution of precipitation, the patterns are multidirectional. According to the chronicles of nature the response of ecosystems to climate change is ambiguous. In the Komandorsky nature reserve displacement of some phonological events has been detected and it can be interpreted as response to warming, in the other two reserves clear unidirectional changes have not been found out.
