Earth is Trapping Much More Heat Than Climate Models Forecast (theconversation.com) 120

What happens if you track how much heat enters Earth's atmosphere and how much heat leaves?

You discover that Earth's energy budget "is now well and truly out of balance," three climate researchers write at The Conversation: Our recent research found this imbalance has more than doubled over the last 20 years. Other researchers have come to the same conclusions. This imbalance is now substantially more than climate models have suggested... These findings suggest climate change might well accelerate in the coming years...

[T]he burning of coal, oil and gas has now added more than two trillion tonnes of carbon dioxide and other greenhouse gases to the atmosphere. These trap more and more heat, preventing it from leaving. Some of this extra heat is warming the land or melting sea ice, glaciers and ice sheets. But this is a tiny fraction. Fully 90% has gone into the oceans due to their huge heat capacity...

The doubling of the energy imbalance has come as a shock, because the sophisticated climate models we use largely didn't predict such a large and rapid change. Typically, the models forecast less than half of the change we're seeing in the real world. We don't yet have a full explanation. But new research suggests changes in clouds is a big factor. Clouds have a cooling effect overall. But the area covered by highly reflective white clouds has shrunk, while the area of jumbled, less reflective clouds has grown.

While we don't know why the cloud are changing, it "might be part of a trend caused by global warming itself, that is, a positive feedback on climate change. These findings suggest recent extremely hot years are not one-offs but may reflect a strengthening of warming over the coming decade or longer...."

"We've known the solution for a long time: stop the routine burning of fossil fuels and phase out human activities causing emissions such as deforestation."

    We can be parboiled even faster.

    So the question is how hot does it have to get to move Earth's radiating wavelength to 13 microns, off the CO2 peak.

    Is there a physicist in the house?

    • You make the earth a bit warmer, create clouds, and a good portion of the band your asking about never reaches the surface into the @thesurface budget, it also does not go to space until the clouds dissipate. Clouds cool during the day, Retain heat under a deck during the Night. But eventually, you get a clear night and the surface radiates IR to a few kelvin of space.

      The long term carbon measurement has been proxied, has the long term cloud population and transparency. My bet is more temp, higher c
    • Peak blackbody radiation is inversely proportional to temperature, but humans can only survive in a pretty damn tight band of temperatures. Humans would be vaporized or frozen solid before the peak shifts off the CO2 band.
    • Just the wavelength of the peak frequency?

    Between all the permafrost melting across Russia to methane to massive fossil fuel use, how can anybody be surprised? I have long viewed the worst possibilities as the most likely. The most likely predictions always seemed pretty damn optimistic. We fucked.

      I recommend this NOVA episode Arctic Sinkholes [youtube.com] (full episode) from Feb 2022, described in the articles below.

      In the Arctic, enormous releases of methane, a potent greenhouse gas, threaten the climate.

      Colossal explosions shake a remote corner of the Siberian tundra, leaving behind massive sinkholes. In Alaska, a huge lake erupts with bubbles of inflammable gas. Scientists are discovering that these mystifying phenomena add up to a ticking time bomb, as long-frozen permafrost melts and releases vast amounts of methane, a potent greenhouse gas. What are the implications of these dramatic developments in the Arctic? Scientists and local communities alike are struggling to grasp the scale of the methane threat and what it means for our climate future.

      Melting ice is a national security issue now. It's opening up routes for Russian ships that were previously closed for most of the year, or entirely.

    Implications of the New Reality
    Doubling of heating speed shortens response windows, fuels feedback loops, and spikes instability.

    Collapse trajectory is now steeper; best-case scenarios require immediate, unprecedented global action.

    Timeframes are collapsing: impacts once expected in the late 2030s-2040s are now unfolding today.

    Feedback loops (cloud cover loss, methane, permafrost) are likely to compound rapidly.

    Policy inertia is now active harm, as the climate system accelerates beyond our response capacity.

    • They won't do a fucking thing until the American breadbasket fails. Even then, they may just fucking take Canada.
      The optimists-at-any-cost are nearly as complicit as the deniers.
      It's been pretty fucking clear for a long time that we weren't on the middle-of-the-road projections.
  • > the sophisticated climate models we use largely didn't predict such a large and rapid change

    Our models failed but we know what the outcome will be based on our models. :shakes head in complexity theory:

    Anybody else old enough to remember the scares about global warming snapping the ocean currents into a new ice age?

    Those models may have been the right ones. And nobody is including the accelerating pole shift.

    I am surprised the Europeans aren't hedging that one hard. +4 in Britain is nice; -15 is total

    • Anybody else old enough to remember the scares about global warming snapping the ocean currents into a new ice age?

      Vladivostok, Russia is slightly south of Oza, Spain. In January, the mean daily maximum temperature is 10C in Oza, but -8C in Vladivostok. The difference is about half due to the Atlantic meridional overturning circulation (AMOC).

      So the collapse of the AMOC, would cool Europe and the UK by something like 10C, and correspondingly increase the heating of tropical West Atlantic. It is still considered an approaching tipping point. Physics-based early warning signal shows that AMOC is on tipping course [science.org]

      • I've had to explain the importance of the AMOC to many many people over my life.
        It's pretty simple. Know what the difference between London and Moose River, CA? Other than the fact that Moose River is further south, and has Polar Bears, and rivers that are frozen for 4 months of the year? AMOC.
        People don't realize just how far north most of the "Western World" is.

        Without the AMOC, the Vikings would have been able to walk to Newfoundland.
        That shit is scary.
    • You're making the mistake of thinking of it as one model. There are multiple different models involved in a climate simulation. Here we have the situation that when a bunch of mostly correct models run end-to-end, the final radiated heat is less than expected due to a cloud component of the simulation not working correctly - doesn't mean the whole set of models is wrong.

      The ocean models that you then comment about seem to be accurate and we do have some evidence that the circulation in the Atlantic is weake

      Models fail to be 100% accurate all the time. You then revise them. It's called sci-ence. Maybe you have heard of it? Probably not...

  • It's more of less and less areosols that's making the difference and the models not accounting for that, more countries are scrubbing soot and SO2 out which makes the climate hotter because areosols in the upper atmosphere have a cooling effect

    • As good a bet as any, theyâ(TM)ve observed it in a localized way in shipping lanes. What I do not understand is why the higher ocean temps are not increasing evaporation rates and cloud cover.

    • by q_e_t ( 5104099 )
      The models do try to account for aerosols, it's just not trivial, hence as more data becomes available, modelling is improved. But the modelling from 40 years ago is still pretty much OK. But things could diverge (get worse than predicted) faster than old models predicted from this point on.

    ... the climate model forecasts are garbage. Remind me again why we should pay attention to them if they are wrong?

    • ... the climate model forecasts are garbage.

      No, they're accurate. Even 50-year-old climate models correctly predicted global warming [science.org].

      Remind me again why we should pay attention to them if they are wrong?

      Leaving aside that they're right. The reason you should pay attention to them is that they can be used to uncover the mechanisms at play, and therefore the have insight into the impacts of various actions or inactions.

    • The models said, "Do something, for Christ's sake!"

      The climate said, "DO SOMETHING, FOR CHRIST'S SAKE!"

      And your answer to the difference in intensity is to discard the prediction? Fuck off.

      The important part is the need to act. And both the models and the climate are fully aligned.

  • This according to Grok and common sense science, all base science point to a linear or gently exponential relationship of cloud cover to ocean temps. The anomaly is that this is not happening. The hope is that somewhere whatever that is will go away, and we will all be living in Seattle until we get the CO2 under control.

  • ...the US congress is openly exacerbating the situation as we speak because they fear retribution if they utter the slightest reservation.

  • If only half of it is true [wikipedia.org], we are soooo screwed.
