80% Chance of Record Heat in Coming Years, Climate Agencies Forecast (apnews.com) 57

The world faces an 80% probability of breaking another annual temperature record within the next five years, according to a forecast released Wednesday by the World Meteorological Organization and the UK Meteorological Office.

The projections, derived from more than 200 computer simulations run by 10 global scientific centers, indicate an 86% chance that one of the next five years will surpass the 1.5 degrees Celsius warming threshold established by the Paris climate accord, with a 70% chance that the entire five-year period will average above that milestone.

For the first time, the agencies identified a slight possibility that global annual temperatures could reach the more alarming 2 degrees Celsius benchmark before the decade's end.

    How is this even news? Anybody paying attention is aware that the cascading effects of man-made global warming have already kicked in and are now ramping up and feeding back on each other. Some minimal fundamental knowledge and basic common sense is all that's required to be aware that this was coming for us.

    I only hope that the new equilibrium isn't a global plus of 5 degrees centigrade or something. That would spell the end of modern civilization, and despite how messy things can be these days I don't want that.

    • Even 5 degrees wouldn't be the end of modern civilization. There are still more than enough room to fit 8 billion people in what would remain the livable areas. The thing most people don't understand is that the problem is that we would be poorer as a whole (not saying some people or even countries wouldn't be richer, but overall mankind would be poorer). And that is compared to if we acted to limit increase by reducing greenhouse gases emissions.

    • Biogenenic methane is going to contribute more and more, and sometime around 2095 will become the primary driver of global warming. At which point it will be out of humanity's hands to control the carbon content of the atmosphere. The sooner we accept that the solution is geoengineering such as stratospheric aerosol injection the sooner we can start actively controlling the temperature of the planet rather than pretending we are not controlling it by adding greenhouse gases.

      I would mod you up, but with the new /. changes I have to unblock like 10 sites, I will not do that. :)

      But I am certain we will hit 5C in a few decades. In reality we need to stop dumping CO2 into the atmosphere now. But with Trump cutting incentives in the US, AI and *crypto I do not see any significant reductions anytime soon.

      I heard Trump is trying to jump start nuclear power, but that is too little to late, the US should have followed France and started 40 years ago. Even Germany is now look at nucle

        Nuclear is dead. It can't compete with renewables and China has proven that you can install vast amounts of it, with storage, and maintain a stable and low cost grid.

        If you want to give the US economy a nice boost, incentivize building more renewables and storage. Solar, turbine, and battery factories on a huge scale. Installers all over the country putting it in. Grid upgrades where needed. Lots of jobs, lots of economic activity, and nice upgrades to quality of life for everyone.

  • As the world heats up, are we going to see an increased migration of people towards Northern/cooler areas?

    • by Sique ( 173459 )
      That is one of the main migration patterns. The other one is from coastal regions to the inland.
    • I mean I don't think it really matters. The world is heavily interconnected and the chaos and fighting that results from all this you're going to get dragged into one way or another.

      If you're over 60 you probably won't die before the worst of it in classic I got mine fuck you fashion but for everybody else interesting times.
    • Not if we build a wall to keep you out.
  • And watch /. heads explode.
  • The best we can do now is mitigate it. And the only really way to do that is to build nuclear energy. If you oppose nuclear energy you favor fossil fuels--and fuck you!
    • We can still limit global temperature rise. If it's too late for 1.5C it might not be too late for 2 or 3C. Which would be a lot better than 5C which would itself be a lot better than 8C.
      The way to achieve that is to reduce (or at the very least limit increase) of greenhouse gases emissions. Now, what is the best way to do that? We don't know. That is the software equivalent of premature optimization. It's best left to the market, through either a carbon tax or a cap and trade scheme. The result will likely

      • Except we do know what the best result is. Germany has spent 500 billion euros on renewables and failed. Their electricty is dirtier per kWh than Texas.

        There are zero examples of a country deep decarbonize with just solar and wind. Zero. Given Germany's failure it is wise to pursue nuclear energy.

        France deep decarbonized their electrical grid decades ago, and they spent a fraction of what Germany did.

        Leaving things to the market is what lead us to 80% fossil fuels.

          Except we do know what the best result is. Germany has spent 500 billion euros on renewables and failed. Their electricty is dirtier per kWh than Texas.

          Let see (source: wikipedia)

          Texas:

          In 2023, the electrical energy generation mix was 51.1% natural gas, 22.2% wind, 13.2% coal, 7.5% nuclear, 5.1% solar, 0.4% other gases, 0.2% biomass, 0.2% hydroelectric and 0.1% other sources.

          Germany:

          In 2023, 55% of energy produced was from renewable energy sources, a 6.6 percentage-point increase from 2022.[6] Within the 55%, 31.1% was attributed to wind, 12.1% to solar, 8.4% to biomass and the remaining 3.4% to hydropower and other renewables.

          So Germany has about 26% coal and 10% gas. Texas is 51% gas and 13% coal. Not sure which one is dirtier. So I asked ChatGPT. https://chatgpt.com/share/6837... [chatgpt.com]
          Its answer is that Germany is cleaner compared to Texas (371 g CO2/kWh compared to 400-500 for Texas). Let say they are pretty comparable.
          But of course, Texans consume (and waste) a lot more electricity and energy in general compared to Germany.

          Leaving things to the market is what lead us to 80% fossil fuels.

          Only because we allowed pollution costs to be externalized. It doesn't have to be that way. The UK successfully got rid of coal power plants. Other countries can as well. That might be using nuclear but we don't know that. It's not because nuclear made in the 1970s than it still is. Anyways, the solution is simple. Just tax carbon and whatever is the winner replacement technology will win. Market forces work, as long as you use them properly.

          Again if you want to compare Germany to Texas, it's 7.7 vs 25 tons of CO2 emitted per person per year overall. It's not all about the electricity, especially not per kWh. The goal is not to produce as much energy as possible, but to get the best standards of living as possible. Emitting too much CO2 reduces standards of living of mankind as a whole.

  • Are there backtesting results readily available for these models? What were their five-year-ahead predictions in 2000, 2005, 2010, or 2015? Were they too high? Too low?

  • "WORLD METEOROLOGICAL ORGANIZATION Global Annual to Decadal Climate Update 2025" https://wmo.int/sites/default/... [wmo.int]
  • THAT is where it comes from. Every 11 years the sun starts burping, and that interacts with our magnetic bubble around Earth which changes weather patterns.
  • Heck, I could have predicted that....and ocean levels will keep rising. And it will get cold in the winter !
  • Almost every single heat record ever in the US was during an El Nino year, which was last year, and we won't have another one within 5 years. So this is provable false based on basic math and statistics.
