I know that, hence why I put winter in quotation marks. It was a joke.

Source? There's nothing happening now that hasn't happened before and it is not scientific to highlight something
after it has happened and say "see that's an exception" because that is just a selection bias.
I've not been affected one jot that I know of. If it wasn't for the news/internet might not even know that there was a flood on.
Bull. Austerity has no bearing whatsoever on this. The Environmental Agency
chose not to dredge the rivers,
chose to encourage flooding to encourage biodiversity that has nothing to do with austerity. The UK has shit weather when it comes to rain but remarkably calm weather when it comes to extremes. We almost never get severe earthquakes, hurricanes, tornadoes, tsunamis etc - yet the UK's Environmental Agency has 11,200 employees - more than the equivalents of Canada, Denmark, France, Germany and Austria combined. Nearly as many as the USA's Environmental Protection Agency. Last year the Environment Agency spent £2.7m on dredging rivers, £20m on total river maintenance ... but £592mn on staffing costs. Totally messed up priorities. Quite frankly we could cut 80% of the employees out the Environment Agency bringing our small islands nation down to that which covers the entirety of Canada or Germany alone and spend more on avoiding this.
There's a saying I've known since being a child: "too many chefs spoil the broth". Does it make any sense to you that the UK would need more employees in its Environment Agency than Canada which has significantly worse weather and is 36 times our size? Does it make any sense to you that the UK would need more employees than Canada, Denmark, France, Germany and Austria combined? Does it make any sense to you that we spend 220x more on wages/pensions than on actually dredging rivers etc which prevents flooding?
Source for new ones please?
97% of UK land is undeveloped, a higher proportion for most other nations. There's more than enough land.
