There is currently a heatwave in Europe. There is plenty of information about the heatwave, with sites such as the BBC running stories related to the extreme temperatures:
While the story in that link does identify that heatwaves are a common occurrence, it also notes that due to human activity, average temperatures have increased, and that heatwaves may become more common.
Most climate scientists are likely to agree that human activity may have some role in warming, but the level of overall warming and the relative influence of human activity have not been determined by any empirical data. Bearing that in mind, it is also worth noting that the current temperatures are NOT unprecedented, as is shown in this story from the New York Times in 1935, when temperatures of 127F (52C) were recorded in Spain.
