Feeling hot hot hot!
Jackie: We’re talking about the heatwave.
Richard: Yes. In the UK this summer has been glorious.
Jackie: Mmm and it’s making a lot of people remember 1976. Now that year it was a really, really hot summer.
Richard: It was. I was a very small boy but I can remember it quite clearly.
Jackie: Yeah. Great Britain and Ireland had the hottest summer average temperatures in the UK since records began. With temperatures reaching over 35 degrees and I think there was something like fifteen or sixteen days with temperatures consecutively over 30 degrees. [Richard: Yes] I mean that was a really big thing then, it was really unheard of.
Richard: It was. I can remember going down the beach almost every day in the summer and in... in the water. Very, very rare in the UK in those days.
Jackie: Yeah and I also remember the... the Government's advice “Save water, bath with a friend”, which was rather controversial at the time.
Richard: Yes and of course the hose pipe bans and all the reservoirs were really low. Yes, it was a really big deal in those days.
Jackie: It was, it was. So now the UK is suffering another heatwave and of course comparisons are being made. What’s the same?
Richard: Well, the cause. They think it’s all to do with the jet stream don’t they?
Jackie: What’s the problem with the jet stream then, Richard?
Richard: Well, it’s further north than normal um... and that basically means that there’s a huge high pressure system based over the north of Europe which leads to hot, hot weather and it lasts for a long time.
Jackie: Okay, so that’s also the situation at the moment. That’s the same then, isn’t it?
Jackie: So the same cause and the same effect you could say. [Richard: mmm]. But there are some differences, aren’t there?
Richard: Well, the big difference is, that it’s not just the British Isles this time is it? There’s um...
Jackie: Yes, much of the northern hemisphere is affected, Richard. Richard: Well, they talk about a number of countries, Sweden for instance.
Jackie: Now they... they’ve had forest fires in the Arctic Circle, which seems a bit bizarre.
Richard: Mmm and of course more recently, Greece. Er... 80 people have been killed in wild... wildfires near Athens.
Jackie: Yeah and Japan is suffering and loads of people have died because temperatures are over 40 degrees.
Richard: And of course all those wildfires in... in California as well. And Canada.
Jackie: Yeah, and um... Brazil too, they’re battling wild... wildfires as well.
Richard: And amazingly, Jackie, in Africa, at a weather station in Algeria in the Sahara desert they’ve recorded the highest temperature ever in Africa.
Jackie: And what’s that?
Richard: 51.3 degrees in the shade. Jackie: Wow, that’s hot.
Jackie: So it’s a global phenomena*, then Richard, rather than a local one this time, and despite the wildfires in the UK, they haven’t actually been suffering nearly as much as the other places around the world. So, why has it been such a hot summer, Richard? It’s not just about the jet stream, is it?
Richard: Well, of course we come round to that favourite, favourite topic, global warming.
Richard: So it’s been going on for several decades now since 1976.
Jackie: So global warming, what... what’s causing that?
Richard: Well, they reckon, don’t they, it’s the rising carbon emissions and it’s caused the baseline global temperatures to rise significantly.
Jackie: But they talk about that being just one degree, right? It just doesn’t seem very much.
Richard: Well, one degree is not very much on its own but the peaks and the troughs are much greater so that means it has an effect on warming the oceans, killing off coral and melting the ice caps which is really, a really big deal. In fact 17 of the last 18 warmest years on record have all occurred this century.
Jackie: I suppose a good thing about the heatwave is you can get a tan without leaving the UK.
Richard: [laughs] Yes, you don’t need to go to a hot country for your summer holidays, you can stay at home.
Jackie: Yeah, and certainly not Portugal, Richard.
Richard: Yes, the month of July has been the coolest in thirty years.
Jackie: And we... we’ve got snow on the highest mountain. Global warming is difficult to explain but that’s just weird.
Richard: We live in Portugal, maybe we should just go back to the UK for our summer holidays.
