Observed Atmospheric CO2 Hits 400 Parts Per Million

symbolset writes "Over the past month a number of individual observations of CO2 at the Mauna Loa Observatory have exceeded 400 parts per million. The daily average observation has crept above 399 ppm, and as annually the peak is typically in mid-May it seems likely the daily observation will break the 400 ppm milestone within a few days. This measure of potent greenhouse gas in the atmosphere should spark renewed discussion about the use of fossil fuels. For the past few decades the annual peak becomes the annual average two or three years later, and the annual minimum after two or three years more."

That ridiculous fake argument masks the fact that they are doing a linear extrapolation, and that that extrapolation is pulling away from the moving average.

Also why my Dad has 11,300 wives.

      Of note is that that temperature chart looks a LOT like a log chart of planetary industrial output, which has leveled off in recent years. Almost as if the warming hasn't come from a persistent gas who's concentration continues to rise even as production falls, but by a transitory gas that is forced into higher concentrations by continuous industrial output, but which falls quickly with falling production and actually works as a significant greenhouse gas.

If temperatures don't keep plummeting as this paper predicts, I'll cheerfully agree in a year or two they were clearly wrong.

The sun beams a whole bunch of heat at earth. Some reflects, some absorbs and increases the amount of energy , in the form of thermal (heat) and kinetic (winds) and to some extent even electrical ionization (lightning). Now CO2 has a number of spectral absorbsion lines that essentially absorb infrared light as well as a number of sidebands of various importance. These where discovered I think by fourier in the 1800s (Who was quite concerned about CO2 greenhouse efffect from the coal fueled industrial era of the time. You can see these absorbsion lines when you shine light through dense CO2 and then refract the light through a prism, although you might need an infra red camera to catch it (I'm sure a chemistry dude would be able to unfumble my explination here). Well this means that its heating up, and absorbing the thermal energy at those frequencies in the atmosphere with all sorts of fun effects but notably as gasses heat up they expand and this brings high pressure areas, some of which is of course going to produce *drum roll* cold places. But none of this changes the simple calculus of how much energy is input into the system vs how much leaves. To deny a fundamental scientific fact of CO2s IR absorbsion and thus heat retention properties like this requires novel physics to be invented and namely a mechanism that somehow stops the physics working here. So far none are proposed, nor need to be, since all the *VALID* data agrees with the theoretically and empirically unescapable conclusion that humans are generating climate change.

With LFTR, a handful of thorium can supply an individual’s lifetime energy needs; a grain silo full could power North America for a year; and known thorium reserves could power advanced society for many thousands of years."

      According to estimates, there are somewhere between 1.9 and 2.8 million tonnes of Thorium economically available right now - that's economically available with no use whatsoever for Thorium! The total crustal Thorium content is estimated at 120 trillion tonnes.

      From the same article:

      In event of a thorium fuel cycle, Conway granite with 56 (+-6) parts per million thorium could provide a major low-grade resource; a 307 sq mile (795 sq km) "main mass" in New Hampshire is estimated to contain over three million metric tons per 100 feet (30 m) of depth (i.e. 1 kg thorium in eight cubic metres of rock), of which two-thirds is "readily leachable". Even common granite rock with 13 PPM thorium concentration (just twice the crustal average, along with 4 ppm uranium) contains potential nuclear energy equivalent to 50 times the entire rock's mass in coal, although there is no incentive to resort to such very low-grade deposits so long as much higher-grade deposits remain available and cheaper to extract. Thorium has been produced in excess of demand from the refining of rare earth elements.

      So if we were to start actually having a use for Thorium, chewing up plain old granite would yield 50x the energy of coal. If we could only tap 10% of the crustal supply, we'd have a 1.8 billion year total energy consumption supply (not just electricity) at current consumption.

      If you're looking at comparing proportionate changes in temperatures, you need to work in Kelvin (or if you really insist on sticking with Fahrenheit, degrees Rankine). I'm not sure what numbers you're pulling out of Wikipedia, but you seem to be saying that average temperatures are 14degC, and current temperature is 14.4degC ; that's 287.16 and 287.56 K respectively, or a 0.14% relative change. I completely fail to see where you're getting a 5.6% relative change from.

      Similarly, going to 400ppm from 280ppm is a 42.8% increase on the original reading. The zero for levels of CO2 is, unsurprisingly, 0ppm (also 0%, 0 [bloody Slashcode : incapable of displaying the permil character entity], 0ppb, 0ppt and zero by lots of other measures of concentration).

      I suppose that you could make a case for using a temperature difference between the Earth's surface and the cosmic microwave background radiation, as the planet doesn't actually live in a cryostat. That would make the relative increase in temperature (against background) 0.13%.

      But I really can't understand what your numbers are, or where you're trying to come from or where you're trying to go.

      You're right about the decimal point. I've actually googled a "ppm to percent conversion calculator" today.

I'm not talking about having memorised more than a few dozens of logarithms (for estimating things mentally), but some basic arithmetic. How do you make change at the cash drawer, or check values/ whatever currency you're using today at the supermarket? Do your overseas expenses claims, even?

      Hint : "ppm" is parts per million ; "percent" is parts per centum, and as you'll remember from your Latin (or French, or Spanish, depending on which foreign languages you learned), "centum" is a hundred. So the conversion factor is *10000. Or just slip the decimal point 4 places to the right. 1% = 10,000ppm ; 1ppm = 0.0001%.

If we were all controlled by a hivemind and made CO2 decrease our highest priority, stopping CO2 production could be done in 20 years (there's enough nuclear power to sustain our needs, and we have electric vehicles - technologically it's already possible). After that, the oceans would absorb the excess CO2 and bring it below 300ppm in about 300 years (according to a study I sadly can't find now). So absent some miracle like fusion reactors even in a best case scenario it would take at least 150 years to get below 350.

It is estimated that this event killed between 80 and 96% of all animals and plants on land and in the sea. The end-Permian extinction was initiated by an increase in global temperatures that was caused by greenhouse gases from widespread volcanism. This modest temperature rise started a cascade of events that culminated in the release of massive amounts of poisonous gas into the air and sea.
