Figure 1 (IMAGE) Institute for Basic Science Caption Climatic and ecological responses to dust injections of 400 million tons from a Bennu-type asteroid impact. Spatial changes of surface temperature (upper left), total precipitation (upper right), percentage change of terrestrial net primary productivity (lower left) averaged over the first 24 months, and percentage change of marine net primary productivity (lower right) averaged from 10 to 38 months after the impact relative to the control simulation.
