Flowering Late or Early - Climate Change?

With the lack of frosts and the generally moist and relatively warm conditions, there are lots of wild flowers open in my Cambridgeshire garden that would normally be dormant such as the Red Campion, Dandelion, Primrose, Knapweed, Chicory (a new self-seeded species this year) and Chickweed plus some naturalised species - Linaria, Alkanet and Corydalis. Various garden perennials are still flowering or are starting early like the Jasmine and Erysium (wallflower) while some annuals such as Cosmos and Marigolds are from this year's seeds.
