For centuries, British flowers have been blooming like clockwork. A few months into spring, sometime around May or June, the nation bursts into color.
Since the early 1980s, however, hundreds of plants have grown out of sync with the seasons, which means they're also unraveling from the complicated tapestry of interactions that keep ecosystems sustainably functioning.When analyzing the first blooms of 406 plant species from 1753 to 2019, researchers found a clear and worrisome shift.
Obviously, not all plants bloom at the same time. Herbs and trees are the first to flower, sometime in mid-April. While shrubs take about a month longer to open up.Today, human-caused global warming is progressing at a rapid and unprecedented rate, and it's impacting the very function of Earth's ecosystems.Early spring warming in the UK appears to be changing the amount of rain that falls and the snow that melts, and both of these factors are important when it comes to a budding flower.
