Date Time Trophic layers are re-shuffled as nature’s calendar shifts across a continent With climate warming, nature’s springtime events are becoming earlier and autumn events later. By bringing together data across the massive region of Russia and its neighbors, a new study shows that how much events advance, or delay, depends on when and where they occur, and what type of species they concern. Overall, these differential shifts make food chains wobble in the changing climate. Climate is shifting and so is the timing of nature. Over the last decades, research has shown how springtime events become earlier and autumn events later. A new international study shows just how much this rule of thumb differs between regions.
