Rising temperatures and earlier springs will mean that bees will wake up earlier. It’s estimated that they wake up five days earlier than twenty years ago. With more species blooming at the same time than in the past, there isn’t such a continuous, even supply of flowers for the bees. This mismatch between when the flowers and bees are active could threaten the bees looking for food sources. This will also reduce plant pollination and their ability to reproduce and yield crops. Rising temperatures may also mean the bees come out earlier, but they need their timing to align with the flowers to avoid being affected.
