保护区对于保护生物多样性至关重要，但不断变化的气候条件对其效力提出了挑战。例如，保护区网络内的新气候和正在消失的气候表明，现存物种将来可能在保护区内没有合适的气候。此外，潜在的跨界范围转移，即从一个国家转移到另一个国家的转移，也具有挑战性，因为有形（如围栏）和无形（如对比鲜明的保护政策）障碍可能阻碍气候引起的转移。通过气候类似物的透镜，我们研究了全球陆地保护区网络内正在消失的和新的气候，以及在全球变暖2 °C的情况下，保护区之间跨界范围转移的可能性。我们发现，在全球范围内，24%的保护地的气候将不再受到保护，在其中心位置的500公里半径内（表明保护区网络内的气候消失），而36%的保护地将获得以前没有保护的气候（表明保护区网络内的新气候）。此外，我们发现潜在的跨界范围转移是广泛的，但可变的;例如，在气候变化下，欧洲23%的受保护气候和非洲>50%的受保护气候位于与重点保护区不同的国家。随着全球保护界积极审议保护框架（例如到2030年达到30%），我们的研究提供了通过战略保护行动减少全球保护区网络内新气候和消失气候的流行率的见解，并强调了制定和适应超越国界的目标和战略的重要性。
Protected areas are essential to conserving biodiversity, yet changing climatic conditions challenge their efficacy. For example, novel and disappearing climates within the protected area network indicate that extant species may not have suitable climate in protected areas in the future. Further, potential transboundary range shifts, those that involve movement from one country to another, are also challenging because physical (e.g. fencing) and non-physical barriers (e.g. contrasting conservation policies) may impede climate-induced movements. Through the lens of climate analogs, we examined disappearing and novel climates within the global terrestrial protected area network and the potential for transboundary range shifts among protected areas under global warming 2 °C above preindustrial levels. We found that globally, climates in 24% of protected lands will no longer be protected within a 500 km radius of their focal location (indicating disappearing climates within the protected area network), while 36% of protected lands will gain climates not previously protected (indicating novel climates within the protected area network). Further, we found that potential transboundary range shifts are widespread but variable; for example, 23% of protected climates in Europe and >50% of protected climates in Africa under climate change are located in a different country than the focal protected areas. As the global conservation community actively deliberates conservation frameworks (e.g. 30% by 2030), our study offers insights to reduce the prevalence of novel and disappearing climates within the global protected area network via strategic conservation actions and underscores the importance of setting and accommodating targets and strategies that transcend national boundaries.
