Marine turtles utilise terrestrial and marine habitats and several aspects of their life history are tied to environmental features that are altering due to rapid climate change. We overview the likely impacts of climate change on the biology of these species, which are likely centred upon the thermal ecology of this taxonomic group. Then, focusing in detail on three decades of research on the loggerhead turtle (Caretta caretta L.), we describe how much progress has been made to date and how future experimental and ecological focus should be directed. Key questions include: what are the current hatchling sex ratios from which to measure future climate-induced changes? What are wild adult sex ratios and how many males are necessary to maintain a fertile and productive population? How will climate change affect turtles in terms of their distribution?
海洋龟类利用陆地和海洋生境，其生命史的几个方面与由于快速气候变化而改变的环境特征有关。我们综述了气候变化对这些物种生物学的可能影响，这些影响可能集中在这个分类群的热生态学上。然后，我们详细关注了 30 年来对红海龟（Caretta caretta L.）的研究，描述了迄今为止取得的进展以及未来实验和生态研究的重点方向。关键问题包括：目前的幼龟性别比例是多少，以便衡量未来因气候引起的变化？野生成年海龟的性别比例是多少，需要多少只雄性才能维持一个有生育能力和有生产力的种群？气候变化将如何影响海龟的分布？
