| Dr Sparks was one of the lead authors of a Europe-wide study, published last August, that provided "conclusive proof" that the seasons were changing. | |

| The researchers said spring was beginning on average six to eight days earlier than it was 30 years ago. | |
| He said that the latest figures from the Met Office came as no real surprise, and were consistent with climate models that projected a rise in temperatures. | |
| "Certainly, this years is going to see a very early spring, there is no doubt about that. we have seen lots of things leafing or flowering a lot earlier that we would expect to see them appear. | |
| "This spring has demonstrated that different species change at different rates to temperature," he added. | |
| "The most obviously sign of this at the moment is that oak trees have come out into leaf very well, but many ash trees are still quite bare. | |
| This could present problems for local food chains, he observed. | |
| "You may have a situation where an insect relies on a particular plant, and birds or other animals rely on that insect further up the food chain. | |
| "If there is a breakdown in the synchrony between them then it could be disastrous," Dr Sparks warned. "We may have a butterfly species, for example, whose caterpillars feed on only a very narrow range of plants. | |
| "They must maintain synchrony with those plants; if they don't then that species will suffer badly." |
