UN Says Climate Change 'Out of Control' After Likely Hottest Week on Record (theguardian.com) 239

The UN secretary general has said that "climate change is out of control," as an unofficial analysis of data showed that average world temperatures in the seven days to Wednesday were the hottest week on record. From a report: "If we persist in delaying key measures that are needed, I think we are moving into a catastrophic situation, as the last two records in temperature demonstrates," Antonio Guterres said, referring to the world temperature records broken on Monday and Tuesday. The average global air temperature was 17.18C (62.9F) on Tuesday, according to data collated by the US National Centers for Environmental Prediction (NCEP), surpassing the record 17.01C reached on Monday. For the seven-day period ending Wednesday, the daily average temperature was .04C (.08F) higher than any week in 44 years of record-keeping, according to the University of Maine's Climate Reanalyzer data. That metric showed that Earth's average temperature on Wednesday remained at the record high of 17.18C.

Climate Reanalyzer uses data from the NCEP climate forecast system to provide a time series of daily mean two-metre air temperature, based on readings from surface, air balloon and satellite observations. The US National Oceanic and Atmospheric Administration (NOAA), whose figures are considered the gold standard in climate data, said on Thursday it could not validate the unofficial numbers. It noted that the reanalyzer uses model output data, which it called "not suitable" as substitutes for actual temperatures and climate records. The NOAA monitors global temperatures and records on a monthly and an annual basis, not daily.

      OTOH, it's not "we can't control it", but rather "we don't choose to control it.".

      Unless you're including geoengineering in your solution space (which I think we should!), we actually can't control what's going to happen over the next years and even decade or so. Even if we halted all greenhouse gas emissions instantaneously, it would take decades for atmospheric levels to decline and warming to reverse.

      What we can choose to control, though, is how much worse we make it, and how fast. Not that it's easy. Just shutting off all greenhouse gas emissions is impossible, and even reducing them rapidly is difficult and expensive.

      But I think it's clear we need to make more progress, faster. IMO, we need to enact carbon taxes and carbon tariffs. They don't need to take effect immediately to have rapid impact, either. If people know that fossil fuels are going to get significantly more expensive in 5 years, or even 10, that will cause many of them to make different decisions now when purchasing appliances, vehicles and other infrastructure.

        Geoengineering is dangerous. We don't know the side effects. There are lots of proposals, each with their down side. And they're all expensive even if they work as planned.

        Carbon capture can never be cheap. Thermodynamics guarantees that we're going to need to pay more energy to recapture the carbon than we got during the process of releasing it. Nuclear power or VAST amounts of solar power might make that doable. But it won't be cheap.

        Solar shields in space can reduce the temperatures, but they reduce them most around the equator, which is likely to turn off the jet stream causing effects we can't calculate. Also it wouldn't be cheap.

        And the carbon once recaptured, needs to be stored in some permanent way. Forests don't count except as a temporary sink.

        All this is doable, but we'd need to choose a path, stick to it, and pay for it.

        • Yes, lots of research would be required. I think we should put a few billion dollars into doing that research. Not least because I think deliberate geoengineering (as opposed to the accidental geoengineering we've been doing) will be done, so we should make sure we understand the costs, benefits and side effects in as much detail as we can.
        • "Forests don't count except as a temporary sink."

          This is false. Even if they burn down, not all of the carbon is released. They don't sequester all of the carbon they're made of permanently, but that doesn't make them not carbon sinks.

          • by HiThere ( 15173 )

            They are sinks, and they are temporary. I wasn't assuming that they burnt down, but they recirculate the carbon they hold while they live. And they don't live forever. (Centuries, perhaps. I wouldn't go as far a millennia while people are around.)

        • Geoengineering is dangerous. We don't know the side effects

          I mean unless the entire premise behind global warming is bogus then the climate is warmer because of excess CO2. If you reduce CO2 then the side effect should be temperatures returning to normal.

          Outside of some runaway system where it removed ALL the CO2 (which would make it too cold) though if we had the ability to run a machine that captured excess carbon (and itself didn't generate more than it captured) and then stopped when pre-industrial levels were achieved that would be awesome.

        I see nowhere in your comments an option of a reduction in the world's population. With fewer people the amount of pollution produced would decline, we would use fewer resources, more green space would be open since we wouldn't need vast sprawling cities and their heat islands or the continual destruction of farmland to build more rowhomes which would mean cooler temperatures, and the standard of living would increase for people since most could then afford to own a home with grass and trees rather than live in said heat island.

              Well, not *quite*. While its true the environmental impact of humanity tends to be at least proportional to our total population, for any given population a denser geographic distribution will minimize *net* environmetal impact.

          I see nowhere in your comments an option of a reduction in the world's population.

          Population is a solved problem. The number of babies born each year has already peaked and is declining. The only reason total population is still growing is because the global population skews young; we're just filling out the older age brackets, not increasing the number of people added each year by birth. Based on the current trajectory we'll hit a peak population of just under 11B by 2050 or so, and then population will actually begin to shrink... but it will probably happen sooner than that, because the decrease in birthrate is accelerating. This could change if life expectancy is greatly increased.

          If you want to get to peak population and into declining population even faster, all you need to do is to accelerate the growth of wealth and education (especially female education) in the developing world. I'm all in favor of doing that, though in the short term it will probably mean increased GHG emissions.

          If you actually want to start reducing the global population now, the only way is by slaughtering hundreds of millions of people. I am violently opposed to that.

          If you'd like to remove yourself, of course, that's your call. I'd probably try to talk you out of it, but it's ultimately your decision. Do what you think is best.

            Or if it's good enough to start reducing the global population beginning up to 9 months from now, that creates options that don't involve slaughtering anyone.

              What is your proposed method of preventing those births?

              I proposed increasing wealth and education in the developing world, which will accomplish it neatly. What would you do? Forcible mass sterilization? Contraceptives in the water supply? Forcible abortions? Criminal penalties for childbirth? Do you have an option that isn't almost as immoral as slaughtering people?

                Why do you think it will prevent enough births? We may have entered population overshoot long ago, and simply increasing wealth and education may not go far enough in preventing war, disease, starvation and so on.

      Controlling it (and thus, fixing the issue) involves a lot of change to how things are done, and will impact a lot of very rich (and thus, powerful) people, who will likely push back or tie things up in court for eons.
      For the record, I fully agree that something needs to be done, and the longer we wait, the more drastic measures will be needed to correct things.
      Unfortunately, I'm not certain anything can be done without resorting to dictator-like behaviour (irreversible decree that mandates a course correction, stuff like that). I dunno, I"m not a political expert, but I really don't see anything ever happening in any meaningful way.

    • My greatest climate change nightmare is that some segment of earth's population attempts geo-engineering.

      It's inevitable, especially a couple of decades down the road when heat waves begin killing people in non-trivial numbers, and climate refugees become a big problem. I think that would be true even if we were doing a better job of reducing GHGs now.

      Once that genie is out of the bottle there's no going back.

      Sure, but I don't think that's necessarily a bad thing. Geoengineering is necessarily large-scale, so implementing global controls on it should be feasible. Out-of-control AI is much more problematic that way.
