gollum123 writes to mention a BBC article on a study of Europe's changing climate. The study collated information from 17 nations and 125,000 studies involving 561 species. The results indicate that, at least in Europe, 'Spring' is coming earlier and earlier every year. From the article: "Spring was beginning on average six to eight days earlier than it did 30 years ago, the researchers said. In regions such as Spain, which saw the greatest increases in temperatures, the season began up to two weeks earlier. The findings were based on what was described as the world's largest study of changes in recurring natural events, such as when plants flowered. The team of researchers also found that the onset of autumn has been delayed by an average of three days over the same period."
