    Although already 100 years had passed after the Tunguska event, the scientific community is still far from clear understanding of what happened in Siberia on 30 June, 1908. For three nights following the explosion in the Tunguska area, skies over Eurasia were exceptionally bright; glows diminished rapidly thereafter. Recently, the Tunguska explosion was offered as an alternative reason for global warming which is observed today. However, we remind that a loss of synchronism of a trend of temperatures in both Hemispheres of the Earth was recorded only in the first decade after the Tunguska phenomenon. Similar changes in the trend of temperatures was not noted during all the following 10-year periods. We prove that silvery clouds were not major luminescences during the Tunguska event. Therefore, we assert that changes in water balance in the atmosphere after the Tunguska catastrophe could not be the crucial factor affecting global warming.
