Kathie Dello, a climate scientist said the study helps to pin the blame for the heat wave on climate change.
“If searching for a culprit for the intensity of these recent European heat waves, climate change is the obvious culprit,” Dello said in an email. “Attribution is just dusting for fingerprints. Climate change will continue to be a menace when it comes to extreme heat, making these events more likely and more intense.”

Was it used in a figurative sense? What does it mean here?
