I fail to see the basis of this entire thread.
Several here constantly refer to CO2 readings at Mauna Loa. How can anyone take such a thing seriously?

Mauna Loa - Wikipedia
en.wikipedia.org › … › United States Geological Service
Mauna Loa is the largest subaerial and second largest overall volcano in the world

Mauna Loa
Mauna Loa is one of five volcanoes that form the Island of Hawaii in the U.S. state of Hawaii in the Pacific Ocean.

Will one of the Mauna Loa enthusiasts here please explain how any CO2 measurement can be remotely accurate sitting next to the second largest volcano in the world?

If someone wanted to pick a location where they would be guaranteed increasing levels of CO2, on top of a volcano seems an ideal location.

Sex is good. Do you agree?

How would you know? It's apparent that you've never experienced it, and are unlikely ever to experience it; and that frustration over not being able to find anyone willing to degrade himself or herself far enough to be intimate with you is a major driving force behind most of what you have recently posted.

You're left with no better outlet for your unrequited libido than to jack off to images of trannies.

Pathetic.

It is about the effects on a world containing 7 billion+ people. All the lies and flap yap of the deniers cannot hide the fact that we are changing the world in a manner that will have very negative effects on our children and grandchildren.

How do we develop a systematic approach to murdering off a few billion people?

Well now, that is your ambition. The rest of us would like to see a better world for our descendants.

Look, dumb fuck, they have taken measurements there since 1957. And we have other stations around the world, and they show about the same ppm.

Atmospheric CO2 | Scripps CO2 Program

Atmospheric CO2
Measurements of atmospheric CO2 concentration in our program began in 1957 at La Jolla, California and at the South Pole, and in 1958 at Mauna Loa Observatory. These measurements were gradually extended during the 1960's and 1970's to comprise sampling at an array of stations from the Arctic to Antarctica.

Solid circles denote locations of stations for flasks collected for CO2 and CO2 isotope measurements. Open circles denote locations of flasks collected for the parallel program Scripps O2 in atmospheric O2 measurements.

The primary (in situ) record from Mauna Loa is based on measurements made with an analyzer at the site. At all other stations, the records are based on flask samples returned to our La Jolla laboratory for analysis. Flasks have also been redundantly collected at Mauna Loa. Isotopic measurements on flask samples of the 13C/12C and 18O/16O ratios of CO2, which we began in 1978, have gradually been expanded to include all stations where we measure the CO2 concentration.

How do scientists know that Mauna Loa's volcanic emissions don't affect the carbon dioxide data collected there?
By Dr. Steve Ryan, NOAAMarch 8, 2010
Mauna Loa is indeed an active volcano; it last erupted in 1950, 1975, and 1984. Between eruptions, it emits variable amounts of carbon dioxide (CO2) and sulfur dioxide (SO2) from fissures at the summit. The observatory is located on the northern slope of the mountain, 4 miles away from and 2,600 feet lower than the summit, which is 13,675 feet above sea level.

Most of the time, the observatory experiences “baseline” conditions and measures clean air which has been over the Pacific Ocean for days or weeks. We know this because the CO2 analyzer usually gives a very steady reading which varies by less than 3/10 of a part per million (ppm) from hour to hour. These are the conditions we use to calculate the monthly averages that go into the famous 50-year graph of atmospheric CO2 concentration.

We only detect volcanic CO2 from the Mauna Loa summit late at night at times when the regional winds are light and southerly. Under these conditions, a temperature inversion forms above the ground, and the volcanic emissions are trapped near the surface and travel down our side of the mountain slope. When the volcanic emissions arrive at the observatory, the CO2 analyzer readings increase by several parts per million, and the measured amounts become highly variable for periods of several minutes to a few hours. In the last decade, this has occurred on about 15% of nights between midnight and 6 a.m.

These periods of elevated and variable CO2 levels are so different from the typical measurements that is easy to remove them from the final data set using a simple mathematical “filter.”

NOAA’s Earth Science Research Laboratory program also measures CO2 in weekly flask samples taken at over 60 remote locations around the world. The Mauna Loa Observatory baseline CO2 concentrations agree very well with flask measurements taken at a similar latitude around the world, which confirms that the volcanic CO2 does not affect our final results. These measurements all show significant increases in CO2 over the last few years. (You can find this information up through the end of 2007 on our website at www.esrl.noaa.gov/gmd/ccgg/.)

Although the volcanically contaminated CO2 data are removed from the global averages, they are still scientifically useful. I have published two papers in which I used the non-baseline, volcanically contaminated, data to reconstruct a 50-year history of CO2 emissions from Mauna Loa volcano. This is by far the longest continuous record of volcanic CO2anywhere in the world. It shows that the CO2 emissions are greatest right after each eruption and then decrease at a well-defined inverse-exponential rate in the following years.

For example, right after the 1984 eruption, the volcano was producing over 100,000 metric tons of CO2 per year (equivalent to a town of 40,000 people). It has decreased steadily ever since and is now at only about 1,000 metric tons per year, the lowest it has been since our record began in 1958. These measurements are valuable to volcanologists trying to model the evolution of subsurface magma chambers throughout an eruption cycle.

The choice of Moana Loa was specifically to get it away from man-made contaminants of large cities.

I understand Global Warming is scary to many and to some it's so scary they reach for anything to explain it away.

You can't change chemistry or physics. Global Warming is real and accelerating. There is no debate in the scientific community and hasn't been for 15 years.

Curious, the vast majority of those CO2 stations appear to be volcanic islands in the Pacific Ocean. Since no Global Warming shyster has been able to explain why the earth was so warm during the Middle Ages and now I learn all their CO2 stations are sitting on volcanic islands their reading mean less than ever.

Even Al "Snake Oil Salesman" Gore testified that warmer temperatures often preceded increases in CO2.

What percent of our atmosphere is CO2?

Now +0.27 is not all that high, compared to the other temperatures since 1997. Prior to 1997, there are only 3 months as warm as last April. And Dr. Spencer is known for lowballing the increase in temperature.

Spencer lowballs.........the rest of the agencies/organizations highball the data. Everybody knows that. The data MUST match the established narrative.

Got any actual observed, measured data that suggest that those numbers mean anything beyond a simple increase of a trace gas in the atmosphere.

Yes. Got any that say they don't?

Still waiting for the Global Warming nuts to provide the percentage of CO2 in our entire atmosphere.

Curious, they are so afraid of the facts which are why the public now scorn the phony issue.

"Here is a dossier of key facts about carbon dioxide (and its role in global warming):

· It is an incombustible, colourless, odourless, tasteless and non-toxic gas

· It is a plant nutrient and, as the ‘fuel’ of photosynthesis and the creation of oxygen, it is absolutely essential to the existence of life on Earth

· Its fertilisation effect has meant that, thanks to our anthropogenic carbon dioxide emissions increasing concentrations in the atmosphere, crop yields have improved dramatically to date and will continue to improve in the future

· It is a weak greenhouse gas

· Global warming precedes, and then causes, increases in carbon dioxide emissions

· Most global warming experienced since 1950 can be attributed to natural climate variability, rather than enhanced greenhouse gas warming from anthropogenic carbon dioxide emissions. Furthermore the rate of global warming experienced since 1950 has many precedents and is not remotely alarming

Carbon dioxide concentrations today are amongst the lowest found in the entire history of the Earth

· Only 0.04% of our atmosphere is carbon dioxide, which makes it what scientists call a ‘trace gas’; it requires extremely sensitive equipment even to detect it

· There is a very poor correlation between carbon dioxide concentrations and atmospheric temperatures so some thing (or things) other than carbon dioxide must be the key driver (or drivers) of global warming

· Carbon dioxide exerts a diminishing warming effect as its concentrations increase and is today almost entirely exhausted as a greenhouse gas

· At low enough concentrations carbon dioxide could cause catastrophic climate change and the extinction of all life on Earth

· Those who would assert that global warming is man-made and dangerous are denying the facts that global warming has been slowing down at precisely the same time that anthropogenic carbon dioxide emissions have been rising and that no unequivocal causal relationship has ever been established between those emissions and observed global warming.

The world-renowned theoretical physicist Freeman Dyson has said, ‘The possibly harmful climatic effects of carbon dioxide have been greatly exaggerated… the benefits clearly outweigh the possible damage’. Dr William Happer, Professor of Physics at Princeton University, has said, ‘No chemical compound in the atmosphere has a worse reputation than carbon dioxide, thanks to the single-minded demonization of this natural and essential atmospheric gas… The incredible list of supposed horrors that increasing carbon dioxide will bring the world is pure belief disguised as science…. We’re really in a carbon dioxide famine now… increased carbon dioxide will be good for mankind.’
