Spring the fastest warming season in the UK due to climate change
Data given to BBC Weather by Nature’s Calendar, external — a citizen science project by the Woodland Trust — demonstrates how climate change is triggering natural events.
Since 2000 they have used public sightings of plants, animals and fungi to log the effects of weather and climate on nature.
Alex Marshall from Nature’s Calendar explained how important the data is to “see how nature is responding to our changing climate”.
Looking at when bluebells and frogspawn start to appear in the spring shows some clear trends over time.
Both are appearing earlier in April and March respectively.
Frogspawn sightings were the earliest on record in 2024.
First sightings averaged across the UK on 24 February, 17 days before the benchmark or average date, according to Nature’s Calendar.
