Studies indicate the mass death on Earth of a significant number of biological groups, in particular - dinosaurs, at the end of the Cretaceous, 66 million years ago. The final cause of this phenomenon remains the subject of discussion. Currently, there are two main theories: large-scale volcanic eruptions and the impact of an asteroid that formed the Chicxulub crater (Mexico). The production of sulfur-containing gases from the evaporation of the surface layers of the Earth during collisions is now considered the main source of climatic effects, since they form stratospheric sulfate aerosols that block sunlight and thus cool the atmosphere of the Earth and prevent photosynthesis. This paper presents the use of a joint climate model to study the effects of this asteroid on the Earth’s climate. It was established that, depending on the time spent in the stratosphere of the aerosol, the global annual average temperature of the surface air decreased by 18 ° C–26 ° C, remained below zero for 4-30 years and a recovery time of more than 30 years was observed.
