It's claims like this that discredit climate change to people. Every single summer is a new record something or other, and then claiming that it's hotter than it's been in 150k years, people just aren't buying it. Theres no way they know that, none. Even with good science, ice cores, tree rings, all that stuff, people see claims like that and think "these guys are full of shit." And even to people that do believe it, the fear is fatiguing. People throw their hands up in hopelessness eventually.
I know the messaging is designed to be alarming to stir action, but it is backfiring. The claims keep getting bigger to get people to care, but they're just too big for people to believe. The people that handle this messaging, if their goal is to get people to care then they're fucking up, it's having the opposite effect.
