Despite Clean Energy Use, Global Warming is Still Projected to Continue (msn.com) 50

The world's use of clean energy "is rapidly growing", reports the Washington Post, "but not fast enough to keep temperatures in check..."

Many experts say it will be the economics of clean energy that defines the future of the planet — and how developing countries choose to meet their growing electricity demands. "What happens in emerging and developing economies in the next decade in some sense is the whole ballgame," said Jason Bordoff, founding director of the Center for Global Energy Policy at Columbia University. Global greenhouse gas emissions could peak as soon as next year, according to the International Energy Agency, but are not on course to drop sharply enough to contain warming. The world would have to cut its emissions roughly in half by 2035 to meet the 1.5 C target, scientists warn, in part because carbon dioxide stays in the atmosphere for centuries.

Instead, the U.N. projects that nations' current policies will lead to 3.1 C of warming by 2100, or as little as 2.6 C if the strongest pledges are kept. This would represent substantial progress from when the Paris agreement was adopted, when scientists expected a 4 C (7.2 F) rise in temperatures by century's end... Still, the U.N. Intergovernmental Panel on Climate Change predicts "dangerous and widespread disruption" on the current path. The Greenland ice sheet might tip into irreversible collapse, according to the IPCC, threatening cities from New York to Shanghai, while extreme heat and humidity could make large swaths of the world effectively uninhabitable. Scientists also expect a growing toll of disease, crop failures and weather disasters. It would likely take thousands of years for Greenland's ice to completely vanish, but other impacts — like the death of coral reefs worldwide and month-long heat waves — could come in a matter of decades. If countries wish to avoid these consequences, they will have to spend vast sums on adaptation. From now through 2030, poor nations will need up to $387 billion per year to adapt to mounting climate disasters, according to a recent U.N. report...

[Much of the progress on curbing emissions] has come from the United States' switch from coal to natural gas and renewables, and the European Union's rapid embrace of wind and solar power... But the demand for power is also rising, complicating these efforts. According to a recent report from the International Energy Agency, countries are expected to add electricity demand equivalent to the entire nation of Japan every year — thanks to the growth of EVs, the rapid build-out of AI data centers, and a surge in a need for air conditioning in developing countries. That growth in demand means that even as clean energy is added to the grid, fossil fuel use hasn't decreased. And unless countries close coal and gas plants and shut down oil drilling, emissions won't start to come down.

"Two things can both be true: Clean energy is breaking almost every record you can imagine," Bordoff said. "And oil use is going up, and gas use is going up, and coal use is going up."

    Well, apparently, they aren't calculating the energy required to make and maintain things like solar (lithium mining, which is filthy), etc. But I think we're all fucked anyway because we have to worry now about fish farts. [slashdot.org]

      Obviously, they do. This is not some bunch of amateurs, even when the deniers want to style them as such.

      They do. The wider you cast the net the more complex it is to calculate, though. And it also applies to fossil fuel sources, although I've seen people try to compare the expansive footprint of solar to the narrow footprint for fossil sources

    The US and EU can not do it alone.

    China has to stop pretending it's an impoverished developing nation that needs immunity from pollution / climate change requirements. It's a wealthy modern industrial nation that should and should act as such.

    And regarding honest to god developing nations, well, either climate change is an existential threat or it is not. If it is, sorry, even developing nations need to chip in. Immunity from pollution / climate change requirements just says that "existential threat" is just political posturing not reality.

    If the existential threat is real, everyone, developed or not, needs to do their part.

      An American emits more CO2 from oil than a Chinese person does coal. But it's Chinese coal "causing all the problems", isn't it...

        And it, China, is emitting more pollution than anyone else in the world.

          China emits a tiny fraction of US and EU emissions per capita, the only reasonable measure assuming you don't think killing off billions of people is an acceptable solution.

          What's more, last year China installed more solar and wind generation that the US has in its entire history, and it is accelerating.

          It really is the US and EU that need to do more. The really frustrating thing is that we have solutions, we just need to implement them. There are some areas where a bit more work is needed, so maybe we coul

            My own view, fwiw, is that every country can and should be doing much more, with a twofold focus on building out net new low carbon energy and shuttering existing high carbon energy. The thing that might just save us is that the costs of solar, wind and storage in particular have fallen so much and are continuing to fall that they provide their own incentives, eg sub Saharan African economies are importing solar and “skipping ahead” instead of building out fossil-based infrastructure in much the

              Agreed, every country needs to do more. China is the world leader, but even they could ramp up faster, and the government could be a bit clearer about ending fossil fuel use for electricity generation, rather than just relying on the free market to do it.

      So why isn't the US doing its part?
      An American emits more than a Chinese and a European added together.
    • Any country that is a nuclear power is not impoverished. China needs to grow up, but I don't blame them for taking advantage of geopolitics that are looking at it otherwise. It's everyone but China that needs to get their shit together and categorize them appropriately, and hold them accountable.

        It is not China that needs to grow up. It is the US.

          US emissions are down, a little behind the EU.

          China's emissions are still growing.

      The US is rated even below China by Climate Change Performance Index: https://ccpi.org/ [ccpi.org]

      China invests massively in renewables and emissions will likely peak now. It has to do much more just as everybody else, but the idea that the US is somehow in a leading position is grotesquely wrong and the "but China" excuse is intellectually and morally poor.

  • A system in which each national government gives priority to its own country, and only focuses on issues that will show results in the next 3 or 4 years, is not well suited for a problem like climate change which demands a whole world unified response. It tends to leave those sorts of problems too late.

    • Common Sense is coming back. The money will run out, the trough will be empty and the climate change piggies will find something else to pursue.
