If you’re wondering what killed the George Harrison memorial tree in L.A.’s Griffith Park, the short answer is irony. I think. I learned about irony from Alanis Morissette, so hopefully I got that right, but I’d better just let Randy Lewis at the Los Angeles Times explain:

Thanks, Randy. (Yes, we’re talking about that George Harrison.)

So that’s the short answer. The long answer, however, could be climate change. The Harrison tree was a Cayman Islands Pine, and bark beetles love pine and bark beetles love it hot. Fewer cold snaps mean fewer beetle die-offs, but even more frighteningly, warmer temperatures may be speeding up the beetles reproductive cycle, triggering a massive increase in the beetle population.
