A new report from an environmental group indicates that summer temperatures in most European capital cities have risen sharply over the past 30 years.
The study by WWF International, formerly the World Wildlife Fund, covered the 15 capitals of the pre-enlargement European Union as well as the Polish capital, Warsaw.
It says the findings add to evidence of the accelerating impact of climate change.
WWF International blames most of the warming on pollution from power stations and has urged the EU to set tougher targets for emissions of greenhouse gases, notably carbon dioxide.
The largest average temperature rises were in Madrid and London, 2.2 degrees Celsius and 2 degrees respectively, with the lowest in Dublin and Copenhagen at 0.7 and 0.2 degrees.
