Earth just soared past yet another climate change milestone

: 410 ppm/month in 2018 a.d.

The Earth's atmosphere is more saturated with greenhouse gases now than at any other time in human history. For the first time on record, the average amount of carbon dioxide — the main long-lived gas responsible for global warming — in the air passed 410 parts per million (ppm) for an entire month.

Thanks, M.

I just saw the same at the Post:

For the first time since humans have been monitoring, atmospheric concentrations of carbon dioxide have exceeded 410 parts per million averaged across an entire month, a threshold that pushes the planet ever closer to warming beyond levels that scientists and the international community have deemed “safe.”

Just a little reminder. In 2013 the US government NOAA/Scripts institute agreed we crossed the 400 ppmv threshold for 6 days total for the entire year.

This is 2018, just 5 years later, we broke through the 410 ppmv threshold in late March with expectation of peak in late May or early June. However we first crossed it last year in late April 2017 and last year we peaked out around early May with the monthly average for May 2017 coming in at

May 2017: 409.65 ppm
May 2016: 407.70 ppm


Clearly this year May will be well above 410 ppmv and last year had just a few days over 410 so it makes a good analog to 2013 and 400 threshold.

What I am trying to get at is we are now absolutely averaging 2.5 ppmv additional annual CO2 rate of increase over the last 5 years so all the folderol about decreasing emissions has been clearly and scientifically disproven.

For sure Tanada
Our self made climate time machine is running full speed to mass extinction event six.

"all the folderol about decreasing emissions has been clearly and scientifically disproven"

Probably true, unless carbon feedback are starting to kick in in a big way, in which case we are really and truly f'd.

[dissident]

Acceleration of CO2 emissions should be recognized as one of the key aspects of global warming. CO2 is like an entropy proxy. All sorts of processes that maximize entropy generate CO2. This includes human activities, but it also involves natural processes as well. Cryosphere carbon is not the only story. Chemistry change in the oceans and heat stress on plants as well as soils is generating more CO2 as well.

Unfortunately we get retarded drivel such as currently on the peakoil front page about some "weaker warming than expected" junk science and never any recognition of such terminal details.

Oh and that would be the peer reviewed paper published in Journal of Climate with Judith Curry as co-author? The same Curry who has published several hundred papers and won a number of awards for her research in various climate topics? Hardly "retarded drivel" or "junk science".
Perhaps you should actually read the paper.

Greenhouse gas concentrations surge to new record
Concentrations of carbon dioxide in the atmosphere surged at a record-breaking speed in 2016 to the highest level in 800 000 years, according to the World Meteorological Organization's Greenhouse Gas Bulletin. The abrupt changes in the atmosphere witnessed in the past 70 years are without precedent
The last time the Earth experienced a comparable concentration of CO2 was 3-5 million years ago, the temperature was 2-3°C warmer and sea level was 10-20 meters higher than now.
The rate of increase of atmospheric CO2 over the past 70 years is nearly 100 times larger than that at the end of the last ice age. As far as direct and proxy observations can tell, such abrupt changes in the atmospheric levels of CO2 have never before been seen.
The laws of physics mean that we face a much hotter, more extreme climate in the future.

OK, I assume you are suggesting I'm making this up then? FFS can you actually use Google to find out where that paper is and at the very least read the abstract? It is in Journal of Climate...hardly a junk science publication (although I suspect you wouldn't know the difference).

We are talking about a peer-reviewed publication by researchers who are very well known. I've read the paper, it is easy to get at....why post a stupid comment like this?

I stopped posting on the climate change stuff simply because the idiots on this site (which apparently you represent) can't be bothered to actually read the science that is being published.

The publication in question is one of many that argue to a very low TCS and ECS compared to the range as suggested by AR5. There are other papers that argue for a higher TCS/ECS but ....drumroll....that is what science is about. We called it research when I was doing this. I suspect they call it politicking and money grabbing now.

Earth’s atmosphere just crossed another troubling climate change threshold

For the first time since humans have been monitoring, atmospheric concentrations of carbon dioxide have exceeded 410 parts per million averaged across an entire month, a threshold that pushes the planet ever closer to warming beyond levels that scientists and the international community have deemed “safe.”

The reading from the Mauna Loa Observatory in Hawaii finds that concentrations of the climate-warming gas averaged above 410 parts per million throughout April. The first time readings crossed 410 at all occurred on April 18, 2017, or just about a year ago.

Carbon dioxide concentrations — whose “greenhouse gas effect” traps heat and drives climate change — were around 280 parts per million circa 1880, at the dawn of the industrial revolution. They’re now 46 percent higher.

As you can see in the famed “saw-toothed curve” graph above, more formally known as the Keeling Curve, concentrations have ticked upward in an unbroken progression for many decades. But they also go up and down on an annual cycle that’s controlled by the patterns and seasonality of plant growth around the planet.

The rate of growth is about 2.5 parts per million per year, said Ralph Keeling, who directs the CO2 program at the Scripps Institution of Oceanography, which monitors the readings. The rate has been increasing, with the decade of the 2010s rising faster than the 2000s.

“It’s another milestone in the upward increase in CO2 over time,” Keeling said of the newest measurements. “It puts us closer to some targets we don’t really want to get to, like getting over 450 or 500 ppm. That’s pretty much dangerous territory.”

“As a scientist, what concerns me the most is not that we have passed yet another round-number threshold but what this continued rise actually means: that we are continuing full speed ahead with an unprecedented experiment with our planet, the only home we have,” Katharine Hayhoe, a climate scientist at Texas Tech University, said in a statement on the milestone....

I was reading elsewhere that about half of all the anthropogenic CO2 in the atmosphere has been emitted since 1980-1990, which by coincidence is about when the UN Framework Convention on Climate Change was signed in 1992 committing the nations of the earth to work toward reducing global CO2 emissions.

Unfortunately, there hasn't been any reduction in CO2 emissions at all since 1992....in fact they have increased greatly with another significant increase occurring last year.

Cheers!

Week beginning on April 29, 2018: 409.71 ppm
Weekly value from 1 year ago: 409.02 ppm
Weekly value from 10 years ago: 387.20 ppm

Oddly low that week. Only ~.7 increase from last year's weekly number.

Random fluctuation, or some local disturbance, or machine error...or the beginning of the end of GW??!!

Good Morning Vietnam....

Anthropogenic CO2 Emissions are exponetially strong so maybe a CO2 sink is growing stronger ?!

A) Greening Arctic => Tundra to Forest

B) 1000s KM³ of fresh ice shield melting water is a new temporary CO2 sinkhole

C) Longer growing period

D ) Algae blooming ocean event

Wondering what portion of this increase may already be feedback induced?

[dohboi]

"so maybe a CO2 sink is growing stronger"

I'm not a good enough chemist to know the relevant equations, but it is my understanding that as long as we keep increasing CO2 concentrations in the atmosphere, the oceans will continue to dissolve it as carbonic acid in its waters. The process should be getting a bit less efficient, though, as surface waters continue to warm.

When we finally stop emitting CO2 from fossil sources, as CO2 levels start to drop, then the ocean will start 'giving back' all that carbon it had been absorbing, thus keeping atmospheric levels elevated for much longer (by millennia, at least, iirc) than it would have without this mechanism. So the oceans save us/the planet a bit on the upswing side, but hurt us (assuming there is any 'us' by then) on the other side.
