What would happen if the UK tempuature in winter went from 0-5C to 20-30C within a week and would it work

On Wednesday next week here it's gonna be 4C, the next Wednesday it's 7C which is the January average. The lows over the next week are minus. But what if we had a winter with summer tempautres. Would it work, what would actually happen? Just thinking as this time last year it was freezing cold but went to 10C later. Would it lead to a hot summer and climate change.

It would mess up our ecology. We need periods of frost to help kill off certain pests, and many seeds need a period of frost in order to germinate. So a lack of frost would be felt later in the year, and in subsequent years. Equally, if some food plants start to grow too early, they don’t produce as good a harvest. My apple farmer relative lost his whole first crop when spring came too early a few years ago. The trees blossomed too early, before the bees were ready to do their fertilisation role, so not enough apples grew, and those that did mostly did not reach maturity because of later weather fluctuations.

So our ecology would have to change drastically to something more Mediterranean, I imagine.

If it was that temperature in midwinter, it would be absolutely disastrous for the natural environment, including agricultural crops.
