CO2 reaches 410ppm: Panic now because Earth just hit another slightly significant base 10 number

A trace gas in our atmosphere hit 410ppm for the millionth day on Earth says Grist and this turned the planet in to something different. Who knew 410 was that exciting?

We just hit 410 ppm of CO2. Welcome to a whole new world.

This is not normal: We’re on track to witness a climate unseen in 50 million years by mid-century.

In pre-industrial times, the concentration of carbon dioxide in the atmosphere stood at 280 parts per million. And that number has been rising ever since, warming the planet by 1.8 degrees F (1 degree C) along the way.

It’s Big Number Fear Mongering which works so well on the innumerate. It might be the first time CO2 was this high in 50 million years, but if CO2 is so important, how come temperatures  haven’t gone “to a whole new world”?

Kate Yoder on Grist has the usual calm dispassionate analysis:

As fictional carb-thief Aladdin once said: “Unbelievable sights/Indescribable feeling/Soaring, tumbling, freewheeling/Through an endless diamond sky.”

Frankly, I think Grist missed that in Base 3 this is the incredibly important 120,012 ppm.  Spooky eh?
