Yes we are now a firm 400 ppm. Yet any meaningful interpretation informs us that this does not drive the weather at all. The lobby industry claim that it does based on one decade of coincidence is so utterly wrong headed as to throw science itself into disrepute as it has in fact done.
What it really means is that we have partially recovered toward the geological norm that was suppressed by the million year Ice Age. We actually have a long ways to go and we will not be reaching it.
The smoke stacks will be dying soon enough because of our fresh understanding of Dark Matter physics. The only ones after that happens will be the odd smelter.
It's Official: Global Carbon Levels Surpassed 400 ppm for Entire Month
National Oceanic and Atmospheric Administration says level sets new record for world's atmosphere

Marking yet another grim milestone for an ever-warming planet, the National Oceanic and Atmospheric Administration revealed
on Wednesday that, for the first time in recorded history, global
levels of carbon dioxide in the atmosphere averaged over 400 parts per
million (ppm) for an entire month—in March 2015.
"This marks the fact that humans burning fossil fuels have caused global carbon dioxide concentrations to rise more than 120 parts per million since pre-industrial times," said Pieter Tans, lead scientist of NOAA’s Global Greenhouse Gas Reference Network, in a press statement. "Half of that rise has occurred since 1980."
This is not the first time the benchmark of 400 ppm has been reached.
"We first reported 400 ppm when all of our Arctic sites reached that value in the spring of 2012," explained Tans. "In 2013 the record at NOAA’s Mauna Loa Observatory first crossed the 400 ppm threshold."
However, Tans said that reaching 400 ppm across the planet for an entire month is a "significant milestone."
A tweet released by NOAA on Wednesday shows that this development is consistent with rising levels over recent years.
However, zooming to a wider historical lens shows an even more dramatic increase. During pre-industrial times, CO2 levels were at 280 ppm. Scientists have warned that, in order to achieve safe levels, CO2 must be brought down to a maximum of 350ppm—the number from which the environmental organization 350.org derives its name.
Bill Snape, senior counsel to the Center for Biological Diversity, told Common Dreams, "The fact that we are now firmly over 400 ppm for first time in human history indicates to me that we ought to be moving with much more urgency to fix the underlying problem."
