Al Gore calls for a day of prayer and reflection, and bothering your neighbor:
So please, take this day and the milestone it represents to reflect on the fragility of our civilization and and the planetary ecosystem on which it depends. Rededicate yourself to the task of saving our future. Talk to your neighbors, call your legislator, let your voice be heard. We must take immediate action to solve this crisis. Not tomorrow, not next week, not next year. Now.
Scientific American laments the plants
This measurement is just the hourly average of CO2 levels high in the Hawaiian sky, but this family’s figures carry more weight than those made at other stations in the world as they have faithfully kept the longest record of atmospheric CO2. Arctic weather stations also hit the hourly 400 ppm mark last spring and this one. Regardless, the hourly levels at Mauna Loa will soon drop as spring kicks in across the northern hemisphere, trees budding forth an army of leaves hungrily sucking CO2 out of the sky.
…
In the coming year, Scientific American will run an occasional series, “400 ppm,” to examine what this invisible line in the sky means for the global climate, the planet and all the living things on it, including human civilization.
Sorry, we already beat you to it when it comes to summing up what it means:
Since the world hasn’t ended (just like what happened with Y2K) we can now go forward from here.
T-shirts saying “I survived 400 PPM” will be made available if there’s enough interest in comments.
UPDATE: T-shirts now available due to popular demand. See here:

Or if you start with hex 0x1000000, 0.04% of that gives 0x1A36 per 0x1000000. No promises on the math, but I think I got it right.
History repeating itself

So, this is a clear sign of the fragility of the climate models – 400 ppm and no warming? If they had any sense alarmists would shut up in shame.

Just pick times when the wind isn’t blowing CO2 to the collector. The staff are not dummies.

Plant your garden, knowing CO2 will make its chakra strong.
First time in 3 million years CO2 > 400ppm all over BBC news.
Just taken the top off a bottle of Newcy Brown in respect, promise that I will restrict the outgassing of CO2 by consuming with vigour, cheers all.
Has it been studied how representative Mauna Loa is of the CO2 of the atmosphere globally?
Wondering if that is established or just assumed. It would seem to be of some importance to a theory that attaches great significance to the level of CO2 in the atmosphere.
Publicly, they wail, gnash teeth, and rent their clothing. Privately, of course, it’s high-fives all around and party time, because they figure this will give them added ammunition (which it will), which they so desperately need the rushing onslaught of truth, actual science, and rationality.
Hold steady. Don’t fire until you see the whites of their eyes.
I’d be interested in a t-shirt but I am worried that the planet might explode in flames before I received it.
True greens will rejoice, while phoney and ignorant will shed a crocodile tear, while they feast on the fruits of the CO2’s abundance.
Al Gore needs to keep ranting so that he can create/sell/invest in “Green” companies and make millions…$$$$… For a man who almost was the President… He seems to have found his “niche” to make a buck… and forget a thing called “reality”.
I think you should sponsor a HUGE cook out – with lots of charcoal (we all bring the meat and beer) to celebrate!
Guess I will be driving 200 miles to get some of them blue crabs this weekend, for my own celebration!

“Levels….will soon drop as spring kicks in across the Northern Hemisphere, trees budding forth an army of leaves hungrily sucking CO2 out of the sky.”
A note to you “Scientific American” nit wits….trees, and humans, are CARBON lifeforms….nature LOVES sucking CO2 out of the sky….monarch-monopolists LOVE sucking wealth from their serfs….and “armies” destroying lives and properties in staged conflicts, is a favorite technique. I reject this elitist front group’s claim to be “Scientific” or “American”.
My tomatoes are doing quite well this year. Must be the 400 PPM CO2. I’d buy a T with the various disasters on it.

Actually the Pacific Northwest west of the Cascades and coast ranges is a jungle, if that means “rain forest”. By a jungle is usually meant a tropical rain forest. The climax state of the western Pacific NW is a temperate rain forest. Without humans, even the floor of the Willamette Valley would be covered with towering, old growth western hemlock trees.
I’m getting low on “pithy” tees that insult “warmist’s” mentality! Put me on the list for a tee!

We hear everywhere (and it seems constantly) that 2010 was the hottest year in the last 150
According to both satellite data sets, 1998 was the warmest.
RSS:
1 {1998, 0.549},
2 {2010, 0.475},
3 {2005, 0.33},
4 {2003, 0.321},
UAH:
1. 1998 0.419
2. 2010 0.394
3. 2005 0.260
4. 2002 0.218
500 or fight! (that was for all of my Canadian brethren).
In all seriousness, though, I reckon we will never reach 500. We’ll probably be peakin’ shortly, given the way things are trending.
On to 450!
I want damvidmhoffer/vukcevic shirt.
…Can’t type……. …. turning blue…….. Plants taking over computer now……. barely hanging on….. …. love you guys…….
Curiously, the cooling northern hemisphere is part of the reason CO2 levels have temporarily hit 400 as this year’s growing season is very delayed. (at least where I live)
I would like a Tshirt too please.
The average is estimated to have reached 300 ppm in 1910. It will take a few more years for the average to attain 400. I’ll be concerned if it got back to 1000 ppm, a true greenhouse level. Some people might get headaches after prolonged exposure to that concentration. But humans don’t suffocate until several thousand ppm, as during the early Paleozoic Era.
