It's certainly the mildest winter I recall, and going by local tree damage the windiest for a while too at times.
Most spring plants are out in the SE, daffs, snowdrops, ramsons, blue-bells are all showing well developed shoots already, hazel catkins, all the expected signs of spring are here, the only thing holding back the full tide of spring is the amount of daylight, one natural cycle we have not managed to mess about with yet.
But I have to say I prefer these milder winters, but the lack of rain to replenish aquifers in the SE is an issue.
But if global warming has a long term planetary impact as we suspect it migt the longer term future for the UK is that it will get colder, if we lose the warm water current coming up from the Atlantic it will get much colder. Bear in mind that even southern Britain is only about 15deg-lat from the Arctic circle.
