Eco global survival plant rice1/2/2023 Data from these studies can offer many potential insights into how climate change causes extinction and how species might persist. Many of these studies documented local extinctions (i.e., apparent disappearance of a species from one or more sites ref. These historical surveys are then combined with more recent resurveys to infer shifts in species ranges over time, shifts that are potentially related to climate change. These studies typically utilize data from historical surveys, which documented the presence and absence of species at sites along elevational and latitudinal transects. Numerous studies have now documented shifts in species geographic ranges that are potentially related to climate change ( 23 ⇓ ⇓ ⇓– 27). One powerful way to approach these questions is to analyze local extinctions that have already happened. Nevertheless, they may be crucial to predicting how many species will likely be lost in a warming world. Specifically, will species be able to persist by dispersing to remain within their current climatic niche ( 2, 13 ⇓– 15), by shifting their niches to accommodate modified climates ( 16 ⇓– 18), by both, or by neither ( 19 ⇓ ⇓– 22)? To our knowledge, these urgent questions have not been addressed empirically at a broad scale (i.e., across many species, taxonomic groups, and regions). Yet, one of the most basic questions remains largely unanswered: Which changes in climate will actually cause extinctions? For example, will populations and species be driven extinct by shifts in temperature or in precipitation, by changes in annual means or extremes ( 9), and by overall amounts of change or by rapid rates of change? Similarly, the mechanisms by which species can potentially persist in a changing climate are also unclear. There has now been important work on mechanisms of decline in certain species ( 9 ⇓ ⇓– 12). ![]() However, accurately predicting biodiversity loss from climate change may require a more detailed understanding of what aspects of climate change cause extinctions, and of the mechanisms that can allow species to survive. ![]() Different scenarios for species survival are then based on these projected future distributions, combined with different assumptions about the extent to which species can disperse to track their current climatic niches over space. These predictions are generally based on ecological niche modeling of species distributions under future climates, assuming that species’ climatic niches will remain similar over time (where the climatic niche is the set of large-scale temperature and precipitation conditions where the species can and does occur refs. Overall, our results help identify the specific climatic changes that cause extinction and the processes that may help species to survive.Ĭlimate change may be a major threat to global biodiversity in the next 100 years (y) ( 1 ⇓ ⇓ ⇓ ⇓– 6), with predictions for species loss ranging from as low as 0% to as high as 54% ( 5). Specifically, considering both dispersal and niche shifts, we project that only 16–30% of these 538 species may go extinct by 2070. However, we show that niche shifts appear to be far more important for avoiding extinction than dispersal, although most studies focus only on dispersal. Based on their past rates of dispersal, we estimate that 57–70% of these 538 species will not disperse quickly enough to avoid extinction. Surprisingly, sites with local extinctions had significantly smaller changes in mean annual temperatures, despite the widespread use of mean annual temperatures as proxies for overall climate change. We found that locations with local extinctions had larger and faster changes in hottest yearly temperatures than those without. ![]() We used data from surveys of 538 plant and animal species over time, 44% of which have already had local extinctions at one or more sites. ![]() We then use this information to predict the extent of future biodiversity loss and to identify which processes may forestall extinction. Here, we identify the specific changes in climate that are associated with the widespread local extinctions that have already occurred. Although there has been important work on mechanisms of decline in some species, it generally remains unclear which changes in climate actually cause extinctions, and how many species will likely be lost. Climate change may be a major threat to biodiversity in the next 100 years.
