"Global warming" is a misnomer, as it is more appropriately named "climate change," thus the varying experiences.
It's human perspective vs geological and cosmic perspective. A couple degrees don't mean much to us over the course of our very short lifespans. But the average temperature over hundreds and hundreds of years shapes ecosystems.
Pew research finds that all the statistics in the world don't usually sway the masses. You need what's called a "broker of trust" to influence people. Climate change is just too big, too overwhelming, and too scary to consider for most people.
The West Coast is having an almost biblical drought. "Man, this is so weird. Can't wait for it to rain again."
Storms are getting more intense, more unpredictable, and more frequent. "Man, can't wait for these crazy storms to stop popping up. That's so weird."
The coasts are changing, coral reefs are disappearing, and the saline levels are falling around the globe. "Man, what's up with the oceans? That's so weird."
It's too late and it's already here. Unfortunately, this is one cake we've spent years baking and it's just started rising. Even if we stopped all carbon output, all methane production, all that we are currently doing, we've basically already pushed hard enough on the pendulum that it's going to keep moving for years to come. It's not a boiling pot we can keep an eye on and turn down if it starts bubbling over.
The only thing greater in force than the momentum of climate change is the inertia of people.
I think the only way we're truly going to check ourselves as a global civilization is by destroying most of ourselves first.
