You can see I am a newcomer, joining just to give my opinion, I will introduce myself briefly on a footnote so that I can get straight to the point now. As you can see by my username, it's all very specific, the subject touches a nerve with me.
One thing I wanted to say: Winters here are most definitely NOT getting colder.
The other point I wanted to make is that about cold weather being "a novelty here". That's just plain ignorance, no offence, but you just have no idea of what you're talking about.
Thirdly, the problem is bad insulation of some houses (cheap construction), and that's a problem of recently built buildings. Most older constructions are very well built and insulated, sturdily made for proper cold like we used to have and don't have anymore.
To elaborate, I find it somewhat strange that people who have moved to BA in recent years judge that "winters are getting colder" and that "cold is a novelty here" when there's plenty of evidence to the contrary.
It used to be very common to hear people complain about chilblains, some 40 years ago when I grew up in BA*. Nowadays nobody seems to have chilblains anymore, nobody seems to know what chilblains are in fact. Ask any middle aged or elderly local (with good memory) or anyone over 40 - to 45 years of age who's grown up here.
The low temperatures we've been having for the last two or three days (July 16 to 18, 2017) used to be the normal temperature for most of the entire duration of winter, in the past in Buenos Aires. 30 years ago my house used to be a fridge inside and we had the heating turned on for most of the winter. Now the heating is almost never turned on, it's the same house but there's no need.
What's freaky is the warm winter we're having and the warm autumn we had. This cold right now, the cold of a small handful of days in June and the cold of two days at the end of May were just mere punctuations within a very warm winter, and a very warm autumn, and the warm weather is returning right away. Those isolated cold days mentioned above in this paragraph, that was what winter was like throughout, here, in BA, in the past.
Hearing people freaking out because of "the cold" like we're nearly in Antarctica when temperature is mid-teens, people going out dressed for sub-zero conditions and grimacing like braving a blizzard when it is 16° C and sunny, it just rubs me the wrong way up.
I find it deeply depressing and worrying because in my mind this is a sign that people are adapting rather too well to global warming, and that's an invitation for another discussion.
