Hell in a Cell has had some pretty unforgettable matches of late, but WWE's best feud can show why it still matters.

CM Punk sent a heated message to Drew McIntyre on WWE RAW. Drew McIntyre previously took CM Punk out with a vicious attack on the September 2 episode of WWE RAW. The following week, Adam Pearce announced that McIntyre would face Punk in a Hell in a Cell Match at WWE Bad Blood.

Around that time, he was leafing through a science magazine when he stumbled across an article about climate change, which said there could be between a 30 cm to 1 meter rise in sea level before the end of the century.

Drew McIntyre and CM Punk just can’t stand each other. The two have been fighting with each other since WrestleMania 40, and despite beating the hell out of each other at two WWE PLEs, the saga between them doesn’t seem to end.

CM Punk returned to WWE RAW after being viciously attacked by Drew McIntyre, setting up their climactic Hell in a Cell match at Bad Blood. Punk declared his readiness for an intense battle, while McIntyre mocked him on Twitter and promised a decisive final showdown.
