When I said "far more regular basis" I didn't actually mean every day in summer is hot. We have had temps in the late teens this week.
As for animals, what have polar bears got to do with it? We are talking about a few hot days, and I wasn't aware the UK was full of animals who dwell in only arctic like temps. Other than some forms of wildlife I image you have pretty much the same animals in the UK as we do here.
As for it being not common to have temps in the mid-30s, then why is it on an almost yearly basis we hear on the news here that it has been "hot" in the UK - and this has been going on for years (not every year, but often enough).
We are no more set up to cope with hot temps here than you are - other than air con becoming more common, but there are still many, many, people who don't have it. People complain about the heat, of course they do, but they just get on with life, do what they can to mitigate the effects and carry on as normal. We don't start the day early, or end the day early, or have siestas in the middle of the day. Never once have I heard anyone react the way MNers are on this, and other, threads.
The point I am trying to make is that with climate change upon us you are going to have to learn to deal with different weather, just as other people around the world will have to do. As I pointed out, you live in the UK, it is not actually that hot, but it seems to have been gradually getting hotter and yet so many on this thread seem to have lost the plot - and it isn't even summer yet, and you have no real way of knowing whether it will be hot or not. You will either have to adapt, or move someone colder - what else can you do?
The more time I spend on MN, the more the phrase "whinging poms" keeps going through my head.
