This artist’s rendering at left suggests a device that its proponents say will, one day, capture CO2 from the Earth’s atmosphere, and mitigate the growing threat of climate change. But let’s think about this for a moment.
The concentration of CO2 in our atmosphere is fairly consistent from the planet’s surface up to about 60 miles in elevation.
Given that the radius of the Earth is ~4000 miles, and that the volume of a sphere is 4/3 πr3, this means the volume of this section of our atmosphere is 4060 4/3 πr3 – 4000 4/3 πr3, = 2.9 trillion cubic miles.
How many of these devices will be required to make a significant dent in the overall CO2 concentration, given that they need to process almost 3 trillion cubic miles of our atmosphere? What’s the cost per each one? How will they be powered, given that our grid-mix is largely fossil fuels? Won’t this only make matters worse?
This is a sad joke, but even sadder, it’s not the only one out there.

Is Mitch McConnell Still with Us? It’s Important
As we all know, the GOP will stop at nothing to win the midterms, thus making it impossible to remove the sociopathic criminal from the White House.
But did any of us see this coming?
Macabre.

A Profile in Corporate Greed
I just met a woman who’s been a flight attendant for Delta Airlines since the early 1990s, who laments that her company has been ruined by corporate greed, which has trashed so many other things in our lives.
As it turns out, the CEO makes more than $20 million per year, largely based on bonuses associated with cutting costs. “Now we have tray tables that don’t work and seatbacks that don’t recline, and nobody even thinks about fixing them.”
She went on, “This shift has been particularly obvious in the case of Delta, which, when I started with them, was known for its southern charm and the feeling of welcoming its passengers. Now, that gone. It’s like it never existed.”

Firing Pete Hegseth?
Trump should fire Pete Hegseth?
Oh sure. If you’re Trump, Hegseth is the perfect leader of the Pentagon. He’s lawless, stupid, cruel, misogynistic, and racist. No one could possibly match Trump’s values with any greater precision.
