Caribou will likely face population declines rarely experienced in 21,000 years due to climate change. That’s the main finding from our recently published research on the historical resilience of caribou populations.
Caribou, also called reindeer, are a majestic species with remarkable adaptations to the cold Arctic environments of Eurasia and North America. Despite surviving through large climatic fluctuations in the past, future climate warming may cause a drastic decline in caribou populations. Arctic environments are extremely sensitive to climate change, and they are expected to warm two times more than the global average.
In our research, we simulated how caribou population abundance shifted in response to climate change since the last ice age to the present day, and projected it into the future to 2100. This allowed us to directly compare past and future rates of declines.
