I don't disagree with those numbers, but I still don't understand how they bolster the assertion that, "the chance we get into serious trouble due to climate change is significantly reduced". Just because something could happen doesn't mean that it will happen, or if it does, that it will happen when we need it to or that it will even be enough.

Two years ago we needed to start reducing emissions by 4% every year. We didn't. We must now reach a whopping 50% emissions reduction by 2030 to limit temperature increases to 1.5C, because the current path we are on could increase temperatures by 4.4C by 2100.

Getting every nation to ditch their ICE vehicles has to happen, yes, but it's not that simple. You can't just ban the sale of new ICE vehicles and expect that 7% to drop to 0%, because everyone who already owns an ICE vehicle is going to keep driving it until they've decided they're done with it for whatever reason. So, the only way to get to 0% ICE vehicles by 2030 would be to make it illegal to operate one - today.

Politics is involved. Getting large swaths of America (or anyone in any nation with an affinity for an ICE vehicle, but this subset of folk is a great example) to give up their gasoline and their trucks and their mustangs is like asking someone to stop breathing. Asking developing nations with little money or ability to modify their infrastructure to support only ICE vehicles over the next eight years is an outstandingly daunting task. I could go on and on, and while I admire your hopefulness, what you're saying requires the entire world to accomplish the same goal in a far shorter amount of time than we actually have.

I want to view the future through rose-colored glasses. I want to have high hopes that EVs will save us.

They won't.
