A couple of days ago when I was looking for rabbit damage I noticed that the hawthorn (Crataegus monogyna) seedling in Medlar Wood was already showing green and ready to burst.
This is several weeks ahead of normal bud break time despite the fact that it has been a fairly cold winter.
However, I am sure this is not global warming. Maybe young plants for some reason come into leaf earlier, though I cannot see how this could be an advantage. It would seem to make them more vulnerable to hungry browsers and late frosts.
