Wow. Carbon dioxide concentrations measured at Mauna Loa on April 3 were 421.21 ppm.

Accessed April 8: Recent Daily Average Mauna Loa CO2


April 07: 418.46 ppm
April 06: 418.64 ppm
April 05: 418.71 ppm
April 04: Unavailable
April 03: 421.21 ppm




I never saw a number like that before there, but I will for sure see many more such numbers in the future.

Heckuva job humanity, heckuvajob.

2. We are so screwed.

Even if climate change wasn't an issue, we are destroying the planet in so many other ways.
There is a video on weather.com right now describing a swath of tree deaths from Maine to Florida from salt water incursion.

4. Look at how the Covid pandemic and the related shutdowns took a bite out of that rate

Not a HUGE bite, but a nibble. Didn't last long though.

5. Not even much of a nibble

The dip you see isn't COVID so much as the vegetation of the northern hemisphere making their regular seasonal withdrawal of carbon from the atmosphere. That's clearer if you look at basically the same graph extended back over last few years; there's maybe a little dip in the running average (black curve) but much smaller than you might guess from the single year's worth of data:
