Ireland missed some record breaking temperatures on the continent last week.
The exceptional weather meant the UK joined Belgium, Germany and the Netherlands in breaking national records as exceptionally high temperatures gripped large parts of central and western Europe.
Experts warn that global warming, caused by human activities such as burning fossil fuels that are increasing the amount of greenhouse gases in the atmosphere, is making heatwaves more likely and more intense.
