Record-Breaking Increase in CO2 Levels in World's Atmosphere (theguardian.com) 89

The largest ever recorded leap in the amount of carbon dioxide laden in the world's atmosphere has just occurred, according to researchers who monitor the relentless accumulation of the primary gas that is heating the planet. From a report: The global average concentration of carbon dioxide in March this year was 4.7 parts per million (or ppm) higher than it it was in March last year, which is a record-breaking increase in CO2 levels over a 12-month period. The increase has been spurred, scientists say, by the periodic El Nino climate event, which has now waned, as well as the ongoing and increasing amounts of greenhouse gases expelled into the atmosphere due to the burning of fossil fuels and deforestation.

"It's really significant to see the pace of the increase over the first four months of this year, which is also a record," said Ralph Keeling, director of the CO2 Program at UC San Diego's Scripps Institution of Oceanography. "We aren't just breaking records in CO2 concentrations, but also the record in how fast it is rising." The global CO2 readings have been taken from a station perched upon the Mauna Loa volcano in Hawaii since the measurements began in 1958 under Keeling's father, Charles. The concentrations of CO2 have increased each year since, as the heat-trapping gas continues to progressively accumulate due to rampant emissions from power plants, cars, trucks and other sources, with last year hitting a new global record in annual emissions.

      It's about a 1.1% increase in a year. Roughly speaking the atmospheric reaction formulas were boosted by 1.1%. They are already about doubled from before industrialization, what comes to the CO2. That much more there is CO2 to capture the sun's radiation at the moment.

        Actually, co2 is transparent to sunlight, like other greenhouse gasses. What makes them greenhouse gasses is that they are opaque to infrared light. That ensures the energy gets in, but doesn't get out.

        Infrared is what warmer things radiate more, like things warmed up by visible light.

        • Also, the CO2 molecule re-emits the energy (and warms the air around it) and does not get inundated by photons. Molecular collisions distribute their energy too. I just add this because some believe the warming effect will be saturated, when in fact the more there is CO2 the more capacity to capture and distribute heat there is in the atmosphere.

        • > That ensures the energy gets in, but doesn't get out.

          If it cant get out, it couldnt get in either. It's not a one way mirror.

          • Actually, it quite is. Hence the name, greenhouse gasses: the glass panes in a greenhouse are transparent to visible light. That heats up materials inside the greenhouse which then re-emit it as IR. The panes do reflect that IR back in, where, yet again, it warms up whatever is in the greenhouse.

            At best, the panels do get warmed up, too, and then radiate 50% back in, and 50% back out. But they are nearly 100% transparent to the incoming visible light.

        • Actually, co2 is transparent to sunlight, like other greenhouse gasses. What makes them greenhouse gasses is that they are opaque to infrared light. That ensures the energy gets in, but doesn't get out.

          Hm. Not quite. Stars radiate electromagnetic energy in ALL bands, including infrared. The "opaqueness to infrared" works on infrared coming in and going out. The reason why there is more infrared leaving than what is passed through is because higher frequencies are "slowed down" with interaction with normal matter. (matter heats up from visible light with the energy being reradiated as infrared)

          • Well, yea. That's entropy at work: higher energy photons are transformed through interactions with for that freq opaque materials in a bunch of lower energy photons. Here, from visible to IR.

    Who's idea was it to extrapolate average gas concentration in the atmosphere from a station on a volcano?

    • by MatheoDJ ( 1088103 ) on Thursday May 09, 2024 @01:19PM (#64459979)
      I think I get what you're asking; wouldn't being stationed next to a volcano confound the data, as they are known sources of CO2? Fortunately, wind patterns are very predictable and reliable on the Big Island. So this is straightforward to account for. On the windward side of an island in the middle of the pacific, scientists are able to gain insight into global average levels much better than, say, stationed downwind of a major industrialized city or agricultural region. Considerable CO2 output comes from plowing too, so simply getting out of the city doesn't help as much as one might think. All the air mixing that happens between land and the remote, isolated Hawaiian islands makes it perfect for measuring global average levels of atmospheric carbon emissions. The elevation provided by the volcano further prevents confounding factors like boats, trucks, and even decomposition of sea algae.

    • Who's idea was it to extrapolate average gas concentration in the atmosphere from a station on a volcano?

      Turns out that the observatory is sampling the wind blowing in from across the Pacific, not local emissions. That's why Mauna Loa is such a good site; it's up on a mountaintop and the sampling comes from the Pacific, where there are no local sources upwind.

      If the prevailing winds calm down, they can see local emissions, but they know when that happens.

    The Earth is big, and scale hard to grasp. The atmosphere contains a total CO2 layer of about 4mm (as solid). And it is rain-scrubbed by about 1200mm rain (global annual average). Cause-vs-effect -- CO2 would rise by reduced solubility from warming however caused.

    Nevermind spectrographic saturation of absorbtion at 667/cm.

    • Should we throw some dust up into the atmosphere to chill the planet? I think that'd improve things temporarily. And maybe we'd buy enough time to get our shit together in order to reduced carbon output of our civilization.

      But planning ahead is contrary to millennia of human history. We like to ride things out and then react when things get bad enough that we can't tolerate it any more. Then when things are humming along good we backslide and fuck it up again.

          Nuclear power for mars or a lunar base absolutely make sense, as does synthesising fuel for a rocket using it - since chemical rockets are the only type of thrust engine we currently have that is capable of escaping the gravity well of Mars, and are actually relatively efficient in terms of turning chemical energy into kinetic energy - about 60% for the best ones.

          Great post, my only quibble is that space-based solar power is great for any space-based habitat. Beaming it down to Earth today is a non-starter mostly because of the improvements in panels and storage. When originally proposed in the 1970s it would have been a very good solution if corporate executives had been able to concentrate on something besides bumping up next quarter's stock price (the same reason building new nuclear power plants was abandoned).

    • The CO2 effect does not saturate. The molecules are not inundated by photons, but they re-emit the energy. Molecules also collide with each other and distribute the energy. This means that the more CO2 there is in the atmosphere the bigger is the capacity to capture heat (radiation). The saturation is reached when the atmosphere cannot contain more CO2 molecules, if anything. A big chunk of the CO2 is dissolved into oceans too.

      • by redelm ( 54142 )
        Correct CO2 does not saturate the way H2O does with phase separation. That's why I added "spectrographicly". CO2 is absorbing all it can on its three IR vibratory wavenumbers. Such is apparent from the deep notches on satellite spectra or from calculations. More will do nothing (1e-9) because gasses can only absorb on _very_ specific wavenumbers corresponding to molecular vibratory modes and atomic masses. The IR photon energy cannot be held indefinitely, it will re-radiate randomly, eventually back t

      The Earth is big(ish), but the atmosphere is **NOT**. The best example that I've seen was my meteorology instructor who took a basketball and told us, "You see the bumps? If the Earth were that size they'd be larger than Mount Everest. The cracks would be deeper than the Mariana's Trench." Then he dunked it in water, held it up, and said, "That sheen of water right now? That's thicker than the breathable atmosphere."

      Many portions of the oceans and some lakes are already near their CO2 saturation point.

        Correct on CO2 water saturation. It'd better be or those cute corals die horrible homeless deaths! Thick layers of sedimentary rock (mostly CaCO3) testify to long-term saturation (complex equilibria).

    Global warming from CO2 emissions is supposed to be some huge threat to human civilization and yet should there be a mention of nuclear fission for energy to replace fossil fuels there's all kinds of opposition. Therefore nuclear power must be a greater risk to civilization than global warming. How much of a threat does nuclear power actually pose? There's been a few notable accidents from nuclear power plants built in the 1960s and 1970s but nothing notable from anything built after 1980. Is the problem nuclear power? Or nuclear power from before 1980?

    Because of how little of a threat nuclear power poses I feel very little threat from global warming. For me to take seriously these people screaming like banshees about global warming would require them to accept nuclear power as part of the solution. People opposed to nuclear power while screaming about global warming have a very skewed sense of what poses the greater risk. I can understand opposition to nuclear power if there's also an expectation that global warming is a minimal threat. I can understand supporting nuclear power while not seeing global warming as a threat, this is because there's benefits to nuclear power beyond just lower CO2 emissions. Wanting no more CO2 emissions while opposing nuclear power to get there does not compute, one of these two must be of a greater risk than the other. If the belief is that nuclear power is the greater risk, and global warming threatens us all, then that just doesn't compute.

    You want to tell me that nuclear power poses a greater risk than global warming? Okay then, don't expect me to lift a finger on lowering my CO2 emissions. I can read what risks come from nuclear power and if global warming is preferable to that then global warming must not be so bad at all.
