What has technology got to do with the climate? the 21st century has seen far more violent swings in climate than the 20th century - lots of rain coming down in a short time, alternating with drought. Nothing technology can do about excessive rain...
The claim in the second sentence irks me. The article JUST said the last time Paris had a rain like that was 35 years ago (in the 20th century).
Both France and Britain have been experiencing a higher amount of violent storms in the last ten years. It was a matter of time that Paris experienced it - the delay is because Paris is inland, whereas London looks out to the north sea.
