The effects of climate change on biodiversity are unfolding right in front of our eyes, with the science studying climate change impacts once and for all moving from a predictive to a descriptive one. Ripley et al. (2020) illustrate this new state of affairs elegantly with their research on the grass species of Marion Island, one of the sub-Antarctic islands in the Southern Ocean. There, they compared the physiological response of six out of the nine grass species of the island to warming, and link this to long-term monitoring data of the distribution dynamics of these species across the island. This is an important assessment as the island has seen significant warming over the past decades (0.26 °C per decade), steadily tilting the balance in favour of more warm-adapted newcomers at the cost of cold-adapted native grasses.

空间气候变化生态的三位一体：高分辨率气候数据，长期生物多样性监测和生理实验。评论：“南极洲马里恩岛（Marion Island）外来的入侵性草丛以增加的温度来应对，却以耐寒性为代价”。

气候变化对生物多样性的影响正展现在我们眼前，科学研究气候变化影响的科学一劳永逸地从预测性变为描述性。Ripley等。（2020）通过研究马里恩岛（Marion Island）的草种，优雅地说明了这种新的状况。马里恩岛是南大洋中的一个南极岛屿之一。他们在那里比较了岛上9种草种中的6种对变暖的生理反应，并将其与这些树种在岛上分布动态的长期监测数据联系起来。这是一项重要的评估，因为该岛在过去几十年中出现了明显的变暖现象（每十年0.26°C），并以冷适应的天然草草为代价，稳步倾斜了天平，以适应更多适应新气候的新移民。
