SUMMARY: Canada is continuing research on future wildfires in circumpolar forests related to the global warmirig. In contrast to the research ofB. J. Stocks and others (1996) in which climatic change and their impact on wildfires, fire emission and effects on the atmosphere was analyzed by use of monthly data from four models of the general circulation, in the most recent research ofFlanningan and others (1998) daily data and just one model of the general circulation (Canadian General Circulation Model - GCM) were used. Daily data, rather than monthly data, were used because the weather and, consequently, fire behavior can change dramatically over time periods much shorter than a month. The simulation and fire history results suggest that the impact of global warming on northern forests through forest fires may not be disastrous and that, contrary to the expectation of an overall increase in forest fires, there may be large regions of the Northern Hemisphere with a reduced fire frequency. In this paper the most essential parts from the study ofFlanningan and others, titled "Future wildfire in circumboreal forests in relation to global warming" will be presented together with an insight into the situation over area of Croatia and Slovenia based on the enclosed maps simulating conditions by the end of the new century (about A.D. 2100).
