Global Carbon Dioxide Levels Reach New Monthly Record
mrflash818 writes: For the first time since we began tracking carbon dioxide in the global atmosphere, the monthly global average concentration of carbon dioxide gas surpassed 400 parts per million in March 2015, according to NOAA's latest results. “It was only a matter of time that we would average 400 parts per million globally,” said Pieter Tans, lead scientist of NOAA’s Global Greenhouse Gas Reference Network. “We first reported 400 ppm when all of our Arctic sites reached that value in the spring of 2012. In 2013 the record at NOAA’s Mauna Loa Observatory first crossed the 400 ppm threshold. Reaching 400 parts per million as a global average is a significant milestone."

No correlation as in this picture? Denial gets more desperate by the day.
This was predictable based upon the Keeling curve, which has a seasonal oscillation based upon northern hemisphere plant growth. http://www.climatecentral.org/... About two years ago, the peaks of the CO2 concentration measured at Mauna Kea exceeded 400 ppm. Now the average is 400ppm, and in about two years, the trough of the CO2 concentration will exceed 400ppm.
The way things are going that'll be the last point we see 400ppm until the next extinction event.
Don't be so damn deceitful. His quote in Context:
"In a 2014 interview, he said that "What I’m convinced of is that we don’t understand climate ... It will take a lot of very hard work before that question is settled.""
Hard work involves more studies, and more money.
Dyson, like Muller, believes that the Science isn't settled; it very rarely is. Also, like Muller, Dyson believes that there is Global Warming going on, and (that)
""global warming" (is/)as synonymous with global anthropogenic climate change..."
It's Real, and we Dunnit.
His somewhat pessimistic view is that there is no longer anything that we can do about it, except study it, and prepare for the worst, and put more effort into things that we can do something about.
Now before I get crucified, I should like to point out that if you liquified the Atmosphere, it would only be some 30 meters thick, and you could see through it.
The biggest, and least understood, part of modeling Climate Change is the World's Oceans; which are somewhat deeper than 30 meters, and if I remember correctly, is some 40000 times more massive than the Atmosphere.
The Oceans _are_ getting warmer, and because of dissolved CO2, are more acidic. (This may actually be a form of long-term Climate regulating cycles, but it is happening too damn quick.)
I think you are confusion sensationalist media reports with the actual science. As far as the science is concerned, we're on the same track we've been on for 20 years..
Wow, so /. is going to post monthly updates to CO2 but not monthly updates on the 18 years and 5 months of flat temperatures? The latter is news worthy, CO2 concentrations if you've been watching it, are jumping up and down as if life is consuming it. Like it was food for something which isnt human...
Meanwhile someone discovers a link between Sun pollution, magnatism, heat transfer between planets and the 'void' which may explain away "Dark Energy" as simply being sun pollution. Unspent electrons. Energy for star ships.
Yet /. is more focused on cutting off it's nose to spite its face?
What kind of future does /. want to see? One where we're all accountable for creating food to feed plants and be chastised for it based upon "green" ideology? "Green" ideology which says food for plants is making the planet hotter because CO2 is a "greenhouse gas"? *ALL GASES IN THE ATMOSPHERE ARE GREENHOUSE GASES * because they all absorb some energy vs not having an atmosphere at all!
Oh gosh, where does on start.
I guess I'll take a simple approach.
Svante Arrhenius showed in 1896 that CO2 absorbs much more infrared radiation than Nitrogen or Oxygen, which is nice because it keeps our planet from being an ice ball. CO2 levels then were around 300 ppm.
CO2 levels today are about 400ppm, that is the highest they have been in 800,000 years. And no, CO2 levels weren't this high 800,000 years ago. That is just how far back we can go with ice cores.
Human activity, mostly burning fossil fuels, is pumping 36 gigatons of CO2 into the atmosphere each year.
If you don't buy human-caused climate change, explain to me which one of those facts you disagree with. Or explain to me how you interpret them.

Who moderated this fucking idiot up? Other idiots?
Ozone is still here, because of Montreal Protocol. Read up about it!

It does not take a few years to cause noticeable change in Global Warming. It takes centuries. Maybe your great-great-great-grandkids will intent a timemachine and shoot you for your own stupidity, because it will be them that will be affected. It will also be them that will not be able to do anything about it, except to invent a time machine.
Nothing resolved itself. People took action, and you fucking idiot don't even bother to figure out that someone else saved your sorry ass.
And here's the explanation:
Isolated in the middle of the Pacific Ocean and at over 11,000 feet above sea level, the upper north face of Mauna Loa volcano is an ideal location to make measurements of atmospheric carbon dioxide that reflect global trends, not local influences such as factories or forests that might boost or drop carbon dioxide within their vicinity. The CO2 sensors at Mauna Loa are positioned such that they sample an incoming breeze direct from the ocean, unaffected by human activities, vegetation or other factors on the island. (The Mauna Loa Observatory is high enough that the incoming breeze rides above the thermal inversion layer.)
Volcanoes are considerable sources of carbon dioxide themselves. However, the sampling location was chosen to be normally upwind of Mauna Loa's vent, and Keeling perfected methods for detecting and correcting intervals when the wind blew the wrong way.
Measurements at about 100 other sites have confirmed the long-term trend shown by the Keeling Curve, although no sites have a record as long as Mauna Loa.
