A leading climate change institute says last month was the hottest June worldwide since records began.
Head of Copernicus Climate Change Service, Jean-Noel Thepaut, says the average temperatures in Europe were on average 2 degrees Celsius above the defined normal range for the month.
Mr Thepaut says temperatures over the southwestern region of Europe during the last week of June were unusually high and similar events are likely to occur in the future due to climate change.
