Recent Daily Average Mauna Loa CO2

Out of 15,256 readings, which can be found at the Observatory's data page, extending back to May 17, 1974, almost 50 years ago, 424.96 ppm is the highest ever recorded. More telling it is the only such reading of the 40 that exceeded 424 ppm that didn't take place in 2023.

We're off to a great start in 2024, aren't we?

I know, I know, I know, solar wind, "zillion percent" "by 2050" or "by 2040" "by 2060" or "by whenever", electric cars...

I don't know who we think we're kidding, but some of us are clearly kidding ourselves, but as kidding goes, it's not even remotely funny.

I trust you're having a nice day, and if you are driving in the Northeast, that you are safe.

1. More coal will solve everything. Right? *cough*

2. I remember back when we were terrified that Mauna Loa would someday go above 400 ppm

How naive we were.

Here's a clip that I've been known to watch occasionally, laughing so "that I may not weep." Enjoy.
