Frozen to the bone? Don’t worry, spring is coming early this year, scientists predict
Sightings of snowdrops, hazel catkins and even ladybirds and butterflies have been submitted to the Woodland Trust’s Nature’s Calendar scheme, which asks the public to report natural events which mark the changing seasons.
So far in 2015, there have been reports of snowdrops at 120 locations across the country, hazel catkins at 74 spots and even sightings of ladybirds, small tortoiseshell, peacock and red admiral butterflies, the Woodland Trust said.

A warming climate has seen spring coming earlier, and three of the last four years have seen some of the earliest spring averages the Trust has compiled from its monitoring of the seasons in Nature’s Calendar for the last 15 years.
Research looking at nature records stretching back to the 18th century has found flowers over the last 25 years blooming up to 12 days earlier than previously.
This year’s sightings come after the warmest year on record for the UK.

Dr Kate Lewthwaite, Woodland Trust citizen science manager, said: “People still seem to be surprised to see snowdrops and butterflies in early January, but our warmer climate in recent years means this is now pretty common.
“Records added to Nature’s Calendar by the public have enabled scientists to learn how trees, plants and wildlife adapt to our changing climate.
“If we can ensure our natural environment is diverse, resilient and interconnected it will make it easier for wildlife to adjust too.”
The Trust said it would be working in partnership with the British Science Association to estimate the rate spring progresses this year.
