On the Australian telly news, I saw English people having a lovely time on Brighton beach, because the weather is so warm. But I think that there's more to the story of warm days in the Northern hemisphere. Some of the heatwave effects are not so jolly. Could it possibly have something to do with climate change? https://www.youtube.com/watch?v=dG-GlVSKbJQ
And, by the way, Japan's heatwave is a problem, now, in 2018. The Tokyo Olympics are planned for exactly the same time of the year, in 2020.
