In July 2018, Mann commented on recent extreme weather events striking across Europe, from the Arctic Circle to Greece, and on the other side of the world, from North American to Japan. He said, “This is the face of climate change", “We literally would not have seen these extremes in the absence of climate change". “The impacts of climate change are no longer subtle", “We are seeing them play out in real-time and what is happening this summer is a perfect example of that". “We are seeing our predictions come true", “As a scientist that is reassuring, but as a citizen of planet Earth, it is very distressing to see that as it means we have not taken the necessary action".
