Warmer Temps Mean UK Flowers Emerging Earlier Than At Any Time in Past 250 Years

It's the start of spring in the northern hemisphere, so it's time to (again) look at how much earlier trees are budding and flowers emerging... BBC News reports that new research published in Proceedings of the Royal Society B show that plants in the UK are flowering earlier than at any time in the past 250 years. In particular, the trend is most notable in the past quarter century.WATCH VIDEO: Focus Earth: Warming and the Weather

That conclusion was made after examining the longest continuous instrumental temperature record in the world, the Central England Temperature Record, data from which dates back to 1659. (Yes, 1659...)

After reviewing the CET, researchers determined that a year-to-year difference of 1°C equates to a difference in flowering time of about 5 days. Though there were large variabilities, on average the temperatures recorded in the CET increased by about 1°C through the 1980s and 90s.

Richard Smithers of The Woodland Trust, who worked on the project, said through "there have been other periods [in the record] when temperatures were warm...the last 25 years is certainly the period when the index has been earliest."

All in all, BBC News also reports that on average spring in the UK now arrives 11 days earlier than in did 30 years ago.
