<<Why are they getting so early when the winter weather has been so
unkind? Could it possibly be something to do with solar radiation rather than
global warming (and local cooling)? I understand the sunspot cycle is
becoming active but am not sure whether this means more radiation or less.
Dandelions have a fairly permanent rosette of leaves and so I wonder whether it
is possible that they act as natural radiation detectors and that a certain
level triggers off mass blooming? Gavin might know!

We're actually getting very much the same weather as we had over winter. I
keep an eye on weather patterns (I used to teach geography), and we've had
long periods with high pressure sitting over the UK. Essentially, this
means stagnant air, with little movement, and generally clear skies. In winter,
the land cools rapidly under these conditions as heat is radiated off into
space. So we get a cold spell, and if we've got snow cover, which reflects
heat straight back where it came from, it can get very cold. In summer,
with the more intense sunlight and longer days, the land warms up, and we get
a heatwave. We passed the tipping point a few weeks ago, and we're now
into the period when high pressure means increasingly warm weather.
