Earth is Trapping 'Unprecedented' Amount of Heat, NASA Says (theguardian.com) 225

The Earth is trapping nearly twice as much heat as it did in 2005, according to new research, described as an "unprecedented" increase amid the climate crisis. From a report: Scientists from NASA, the US space agency, and the National Oceanic and Atmospheric Administration (Noaa), reported in a new study that Earth's "energy imbalance approximately doubled" from 2005 to 2019. The increase was described as "alarming." "Energy imbalance" refers to the difference between how much of the Sun's "radiative energy" is absorbed by Earth's atmosphere and surface, compared to how much "thermal infrared radiationâ bounces back into space.

"A positive energy imbalance means the Earth system is gaining energy, causing the planet to heat up," NASA said in a statement about this study. Scientists determined there was an energy imbalance by comparing data from satellite sensors -- which track how much energy enters and exits Earth's system -- and data from ocean floats. This system of data-gathering floats, which stretches across the globe, allows for "an accurate estimate of the rate at which the world's oceans are heating up." Because about 90% of excess energy from an imbalance winds up in the ocean, the satellite sensors' data should correspond with temperature changes in oceans.

    At this point, some amount of climate change is really inevitable. We screwed up badly. But that doesn't mean that there's nothing we can do. The faster we switch to low-carbon or zero carbon energy sources, the less damage we'll have and the more time we'll have to figure out large-scale solutions like geoengineering. So we still need to take good steps.

    So what can you do to help? There are three broad categories you can help, personal, political and charitable.

    In terms of personal activity, you can use less carbon. Easy ways to do so are to eat less meat, use more public transit and drive less. If you do need a new car, consider getting an electric car or hybrid. (In almost the entire US, an electric car will produce less CO2. West Virginia and Wyoming right now are two of the few possible exceptions due to their massive coal use https://www.nytimes.com/interactive/2020/10/28/climate/how-electricity-generation-changed-in-your-state-election.html [nytimes.com]). You can also buy solar panels for your house, use less air conditioning, and get more insulation for your home, which will take less energy to then heat in the winter. All of these things are not just good for the environment but save you money.

    In terms of politics, you can support candidates who support systemic changes which will reduce CO2. In the US, this largely means donating to Democratic candidates, although some are substantially better than others. Unfortunately, Republicans who supported dealing with climate change are often people like Arnold Schwarzenegger and Christie Todd Whitman who have been largely pushed out of the party. (And that's even with Whitman being a very vocal supporter of nuclear power.) If you want to support clean energy without supporting any specific candidates or policies, then you can donate here to a group which lobbies for more government support for solar power https://lets-fund.org/clean-energy/ [lets-fund.org].

    In terms of charitable work, you can donate to charities which help get more solar and wind power. For solar power, there are two good ones. Everybody Solar https://www.everybodysolar.org/ [everybodysolar.org] helps get solar panels for non-profits like science museums and homeless shelters. The Solar Electric Light Fund https://www.self.org/ [self.org] helps get solar panels for developing countries in locations they don't have electric power. This helps provide resources for severely impoverished people. It also helps make sure that as those countries transition into modernization they don't need to go through the same high fossil fuel use that the rest of the world did. Lastly, for wind power, the New England Wind Fund https://www.greenenergyconsumers.org/newenglandwindfund [greenenergyconsumers.org] is a good source. They help build more wind power in the North-East of the US. This is good because right now the North East has very little wind power despite having strong winds, so building more wind power there doesn't put any strain on the grid.

        :Texas has one of the largest green energy rollouts in the world, and its a failure when it comes to reducing C02 emissions.

        The percentage of power that CO2 neutral in Texas has been steadily growing. In the early 2000s, about 10% of Texas's electric power was from zero carbon power sources, with almost all of that being nuclear power. In 2019 that was now 17% with nearly the same percentage nuclear but a massive increase in wind and solar https://www.nytimes.com/interactive/2020/10/28/climate/how-electricity-generation-changed-in-your-state-election.html [nytimes.com].

        :Sure for a couple days a year, we are 100% renewable but for the remaining ~300 days a year or so it can get so bad that we are at 100% CO2 burning.

        Texas pretty much is never at 100% CO2; the nuke plants themselves would make that not the case. But some solar and wind is pretty much always functioning. In any event, burning NG in peaker plants is substantially better than burning coal, with about half as much CO2 per a kilowatt-hour as with coal. Texas's problems are also a bit unique. It has its own electric grid, separate from the East and West grids which are the big US grids. So they both cannot offload excess wind or solar power to other grids, and they cannot get power from elsewhere than needed. There is a project, the Tres Amigas Superstation to connect the Texas grid to the other two grids which will allow excesses from the different grids (especially extra wind from Iowa and Nebraska, excess solar in California, and excess wind in Texas) to go to the other grids, but unfortunately that project is behind schedule and overbudget. But the upshot is that using Texas as an example is really not great. It has its own, pretty unique issues. And even Texas has had an overall increase in percentage of electric power from low CO2-sources. That's true for pretty much the entire US incidentally, with the percentage of low CO2 generally going down.

        To solve this problem what we need are a 1970's level of nuke rollout like France.

        In principle this would be great. Practically, this will take a very long time and a lot of funding which doesn't exist. We need more low carbon power now. Nuclear plants can take a decade to build, and cost a lot.

        Then instead of decreasing production when there is excess supply it needs to be used for one of the many C02->liquid fuel recapture cycles for use in air travel/etc.

        This isn't a bad idea, although my guess is that air travel will be probably be one of the very last thing that will be made carbon neutral. But you can also do a version of this with solar and wind power. One can use the Sabatier process to use excess power to make methane from CO2 in the air, and then one can turn current natural gas plants into high density energy storage systems. But as with anything involving recapture, this is a very long-term plan; we're not really building it now, and my comment was in part to focus on short term impacts that work.

        Your point about nuclear power does touch on one serious problem though. There are environmental groups which have pushed for the closing of a whole bunch of nuclear plants, including Diablo in California and Pilgrim in Massachusetts. Regardless of whether building more nukes now is a good idea or not, closing them down is clearly very counterproductive.

              Your right about everything you said, except for the bits about nukes. You must live in TX, so you know about STP. We could just clone that design and built a couple dozen more its only 30 years old (although the design is still from the 70's). It took 13 years to construct the first time around, surely we can do better the second time around if we don't change the contractor a half dozen times and go through a bunch of political BS to slow it down.

              Just a two copies of that plant would be roughly the same power output as the entire installed wind capacity in TX. 10 copies and we could replace all the NG in use. According to Wikipedia it cost $15B in 2019 dollars to build that plant including all the contractors being replaced and all that bullcrap. So for roughly one year of the texas budget we could wipe out all the remaining coal plants and over half of the NG plants in TX, which would result in effectively 100% carbon free energy production and we probably could do it in under a decade like the french if we wanted to.

            Actually, no, the main cost, not teven included in those calculatoins, of nukes is infrastructure and storage.

            The problem with nuclear power in all of the current generation systems is that they are completely inflexible. In many nuke stations it takes days to even vary average power by a small amount. Complete ramp up or shutdown of a nuclear plant can take a month. Yes, they can be shutdown in minutes in an emergency, but an emergency shutdown is an event that it will take months to recover from. This is often given the misnomer "base load" but really there's no such thing. With about the sole exception of long term processes like Aluminium smelters all electrical load flexes through the day.

            This is where wind power, and even solar wins out. The wind is always blowing somewhere. Wind power is already much cheaper than coal and is becoming orders of magnitude cheaper than nuclear. Remember those costs per MW you quoted? Those already include large amounts of time running below capacity. This means that you can build extra wind capacity which kicks in at moments when the wind is relatively lower and demand is peaking. This means that, compared to a nuclear based grid you can overall reduce the amount of emergency peaker plants.

            This is before you even consider how unreliable nuclear plants are. The entire things often go off simultaneously and they have to shutdown completely in the case of even slight geological activity. If you have a nuclear plant in your grid you have to build the entire grid assuming that the whole thing might disappear instantly. Compare that with wind turbines where tens of them could fail simultaneously, say due to a snall asteroid strike, and you just wouldn't even notice as the thousands of others in the grid took over automatically.

                Provided that you have a time machine so you can go 10 year into the future, get a copy of the graph of power usage then this might work fine. You say "Draw a typical load curve of your local are on a sheet of paper." but that's missing the point entirely. If you go below that load curve then you have excess power that you have to dispose of.

      There are even easier ways that save you money.
      1) Advocate for variable energy prices that more closely match the spot price. Your cheapest electricity should be 2 cents a kw/h and on a typical day the peak should be $0.50 to $1. If the price at the plug actually reflected the generation cost people will shift their use. The 2 cheap electricity is always the cleanest, the peak is coal and natural gas peaker plants*. There are many ways people will shift use with minimal discomfort and large savings. Unfortunately in the places I've demonstrated this the savings are for rich people who have big air conditioners or electric heating. In Oklahoma the median saving was $50/month. And then the advocates for the poor got involved. 2) Higher albedo roofs. They last longer, keep your house cooler, keep your neighbourhood cooler and they keep your house warmer at night because they radiate less heat. They even work in cold places like Canada. In December it is mostly dark so less radiating at night is good, in January - March the roofs are white anyway because of snow cover. *No we can't just install more wind and solar. If we took all the new wind installation last year and used it to charge all the batteries produced last year we would charge them all in under 9 minutes.

        However, even if you are going to die after 18 months, your EV can be resold for someone else to use. Honestly, the best thing you can do with an older car is to have it recycled.

      • The ballpark number of CO2 emissions for EV production I found is 17 tons of CO2. That gives you a ballpark of 100 000km EURO 5 range before the construction emissions are offset.
        The construction costs in CO2 for an ICE car: are the same.

        Oops

        , that was such a no brainer.

    • If you do need a new car,

      Then don't get one. I remember reading that making a new (gas) car from scratch uses the same energy require to propel that car ~ 50,000 miles. Even if that's off by 50%, that's a lot of energy use. A well-maintained, used car can do the job.

        The auto industry, like a lot of other industries, are not set up to facilitate this well.

        There are various bits of my 2004 vehicle that are broken that I have to leave broken, because parts are no longer made to repair, and they are not so standardized as to be readily replaceable/interchangeable. So I can't just eternally maintain a car, the parts needed to do so no longer are available after some time (worst case 10 years in the US).

        So I could go out and buy a 2015 used car, sure. But I have to acknowledge that for the 2015 used car to exist, *someone* had to have bought a new car in 2015. So I can't say that everyone in the world should only buy used cars.

        It would be nice if car manufacturers settled on their designs such that the difference between a 2004 and a 2014 would be greatly reduced and that 2004 cars could have forwards compatibility with some 2014 advancements (e.g. a lot of the form factors of components changed without any specific reason.

        Incidentally, there are a lot of other products where this could apply. For example, the insulating box of a refrigerator isn't going to go bad, but when it's compressor goes or a control board fails, repair is likely not an option, because the manufacturers have nothing compatible with that fridge being made anymore.

          I hear ya' loud and clear about the automobiles, appliances, etc. Someone should start a new company... ;)

          Regarding the autos, junkyards are often helpful for non-power-train items. Power-train parts are usually available for decades as they are picked up by third-party suppliers. If you want to be extra clever about it, very popular classic cars have most/all of their parts reproduced as new, now several decades later.

    Let's cut Congressional funding to NASA and NOAA so they can't afford to take the satellite measurements - no data, no problem - all groundless speculation.

      there was an article on /. a while back where funding was cut to weather satellites. It's caused massive problems with early warning systems for hurricanes and sever storms. But it also limited the amount of data about climate change's effects.

      The sort of people who don't want to address climate change leave no stone unturned and have billions of dollars to spend because addressing climate change will cost trillions and that money is theirs.

    IIRC these heat levels were also seen during the Carboniferous Era, so it can't really be said to be unprecedented.

    • Perhaps unprecedented in human history?
    • IIRC these heat levels were also seen during the Carboniferous Era, so it can't really be said to be unprecedented.

      Correct. It is, however, unprecedented in the 12 years of online article history on The Guardian's website.

      • Why the arbirarily low limit? It's unprecedented in The Guardian's 200 year history which is how long they have been writing articles for. Yes that's right it was founded in 1821, though presumably back then they didn't have an RSS feed or popups asking for more money while reading.

    Am I missing something here? Does anybody with an understanding of human nature think that a single barrel of oil or a single ton of coal will remain unburned while there is a financial incentive to extract and burn it? And, if coal is an example, even if there is no financial incentive. That's human nature, we will never sacrifice even a bit of our present comfort for a possible long term big gain. In the long term, the thinking goes, we are all dead.

      How many people do you see riding a horse and cart to work? We don't need to remove the financial incentive, we just need to supersede it with something better. But "better" requires education as well. Such as a friend of mine who swears that the gasoline engine will never be replaced because people like performance cars. Those are the minds we're dealing with, the kind of people who don't realise an EV family sedan can smoke a Porsche 911 GT3 from the starting line. The kind of people who continue to beli

    I'm all for trying to cut emissions, go green on this and that, but I just don't believe that you can - on a global scale - motivate enough people for the common good (see, for example, the last 50 years).

    We should continue to make those efforts, but really I don't see us really solving these problems until more people start to see them as opportunities - specifically, opportunities to make boatloads of money. So instead of "oh no, there is too much carbon dioxide in the atmosphere" we need more people to say, "ok, you have a wild abundance of CO2 - how could you take advantage of that?"

    Same with this energy imbalance - we need to focus humanity on creative ways to harvest or otherwise make use of it for some form of personal gain.

  • We have been doing a LOT recently to capture solar energy. Renewables advocates rightly point out that we are doing more to collect solar energy and make it useful for more things than feeding photosynthesis.

    But, it also reduces the amount we reflect or re-radiate back into space. Solar panels themselves get hot, mainly due to the infrared they aren't converting.

    Is that heat being taken into account in the deficit? That amount will only increase as we deploy more solar collectors.And it is a good thing, in

    • by swilver ( 617741 )

      Do you have any idea what percentage of the world is covered in solar panels? You'd need 0.1% covered to generate enough power to power the world. We're nowhere close to that, so I think its safe to say this effect is neglible.

    • Yup - the sun-via-solar-to-electricity is ending up producing heat at the end as we we consume this electricity.

      Things to consider:
      - what happens to the solar radiation not captured by panels (turns to heat anyway for most part)
      - what is the ratio of total solar radiation vs what we use today (probably multiple orders of magnitude difference)

      As you say, the point being - we need energy so let's at least let's not cause secondary effects like emitting more green house gases. That's the biggest problem now. L
