Researchers at the IBS Center for Climate Physics have simulated the effects of a medium-sized asteroid impact on Earth’s climate. The study reveals that such an event would lead to a dramatic disruption of the climate, atmospheric chemistry, and global photosynthesis. The impact would cause a “global impact winter” with reduced sunlight, cold temperatures, and decreased precipitation. However, the study also suggests that plankton in the ocean could recover and even increase in abundance, potentially alleviating food crises.
Forecast for 6 months: The immediate effects of the asteroid impact, such as scorching heat, earthquakes, and tsunamis, will continue to be felt. The global climate will remain in a state of chaos, with reduced sunlight and cold temperatures. However, the ocean’s plankton population may start to recover.
Forecast for 1 year: The global climate will continue to be severely disrupted, with temperatures dropping by 4°C and precipitation decreasing by 15%. The ozone layer will also experience a 32% depletion. However, the plankton population in the ocean may have recovered and even increased in abundance.
Forecast for 5 years: The global climate will slowly begin to recover, but the effects of the asteroid impact will still be felt. The ocean’s plankton population will continue to thrive, potentially alleviating food crises. However, the terrestrial ecosystem will take longer to recover.
Forecast for 10 years: The global climate will have largely recovered, but the effects of the asteroid impact will still be visible. The ocean’s plankton population will have become a crucial component of the ecosystem, potentially leading to new food sources and economic opportunities.
