Humans cross the 400ppm climate threshold.

This should scare everyone who's been paying attention:
The level of the most important heat-trapping gas in the atmosphere, carbon dioxide, has passed a long-feared milestone, scientists reported Friday, reaching a concentration not seen on the earth for millions of years. Scientific instruments showed that the gas had reached an average daily level above 400 parts per million -- just an odometer moment in one sense, but also a sobering reminder that decades of efforts to bring human-produced emissions under control are faltering.
It's the first time in 3 million years we've had readings above 400ppm. But there's nothing to worry about, right?
"It symbolizes that so far we have failed miserably in tackling this problem," said Pieter P. Tans, who runs the monitoring program at the National Oceanic and Atmospheric Administration that reported the new reading.
We can probably kiss our chances goodbye of turning this Titanic ship that we're on in time to save the near-certain devastation coming our way. Has our time passed?
"If you're looking to stave off climate perturbations that I don't believe our culture is ready to adapt to, then significant reductions in CO2 emissions have to occur right away," said Mark Pagani, a Yale geochemist who studies climates of the past. "I feel like the time to do something was yesterday."
Considering that when (only back in August 2006) we posted about this issue, we were at 380ppm, in 15 years we'll surpass the 450ppm level.
We really have no idea what we've done, have we?

Rarely do you get a Consilience story such as this -- where Earth meets Music! This is so touching:
They race towards a rubbish truck as it empties its load at a vast landfill on the edge of the city, hauling away bin liners that overflow with household waste. Their hands are black with dirt and their faces are hidden by headscarves that protect them from the high sun.
Then watch this video to see how they sound:
Earth Day 2013!
April 22, 2013 10:59 AM
Today is Earth Day! Over one billion people in 192 countries are participating from London to Sao Paolo, Seoul to Babylon City, New Delhi to New York, Rome to Cairo; people everywhere are taking action in their communities and helping depict The Face of Climate Change.Wondering what's happening around the world? Here are just a few of the events taking place:
In Copenhagen, Denmark -- as well as in six other cities on five continents -- the Danish Cultural Institute is organizing its annual CO 2 Green Drive Project in honor of Earth Day. Runners, walkers, bikers, and skaters are using their cities as canvasses to spell "CO 2" with GPS devices.
All in all, it's going to be an amazing day all around the globe!
