Planet is headed for at least 2.5C of heating with disastrous results for humanity, poll of hundreds of scientists finds

Hundreds of the world’s leading climate scientists expect global temperatures to rise to at least 2.5C (4.5F) this century, blasting past internationally agreed targets and causing catastrophic consequences for humanity and the planet, an exclusive Guardian survey has revealed.

Almost 80% of the respondents, all from the authoritative Intergovernmental Panel on Climate Change (IPCC), foresee at least 2.5C of global heating above preindustrial levels, while almost half anticipate at least 3C (5.4F). Only 6% thought the internationally agreed 1.5C (2.7F) limit will be met.

Many of the scientists envisage a “semi-dystopian” future, with famines, conflicts and mass migration, driven by heatwaves, wildfires, floods and storms of an intensity and frequency far beyond those that have already struck.

Numerous experts said they had been left feeling hopeless, infuriated and scared by the failure of governments to act despite the clear scientific evidence provided.

    We are so fucked unless we force “all” the big corporations to pay for the pollution they caused while making trillions in profit over the decades they polluted and hid the scientific knowledge showing climate change. And even then,if we stop polluting right now, we still might not Make it as a civilisation.

      Hmm I think we need even bigger trucks and also more religion and less gay people. That’ll fix it.

      Unironically, that’s partly due to our emissions coding system. According to the system, a light truck with more seats gets more emissions allowance, incentivizing auto makers to lean into the larger class. That’s why there are so many extended cab pickups, yet so few two-seaters with an eight foot bed. We all know that six-seater Ram MegaCab or the Escalade that seats eight is often only driving one selfish person to work.

          Well, also, increased trans-oceanic shipping (lots of old ships still use bunker fuel, some of the nastiest fossil fuel on the market) and increased air travel and also plus too a bunch of wars keep happening.

          I should note that we do have a solution to the first problem. But it’s predicated on the rapid deployment of a very modern kind of nuclear engine.

          And that means replacing tens of thousands of old ICE engines. Which means spending money. Which private industry hates.

          So don’t hold your breath waiting for any of this shit to change. But do hold you breath around bunker fuel, because jesus fucking christ that shit is gross.

    My favorite part was when corporations lied their asses off to the entire world for over 50 years while simultaneously telling is this is all our fault but if we recycled and didn’t use too much water, gas, or electricity we could undo the harm that we were personally responsible for.

      I’m rather fond of the part where they admitted to those lies, and the US didn’t force them to pay restitutions equal to the cost of mitigating the damage they’ve caused.

        In 2068, I’m sure some entrepreneurial politician will run on the “Prosecute the oil companies!” platform, long after a bunch of them have gone bankrupt and all the damage has long since been irreparably done.

        Until then, we just need to keep looking for the Least Bad politician (the guy who has one hand out to fossil fuel and another to privatized wind/solar) rather than the guy who insists wind farms spread COVID with 5g, and hope we don’t live long enough to reap the whirlwind.

    Sweet! If this is at all obvious to anyone paying attention and I’ve been saying I expect it to happen for years, I’m putting “One of the worlds top scientists” on my resume.

    The only chance we have that I see is the rapid development of fusion into a proper, usable power source, the supplantation of effectively all carbon emitting power plants with non-emitting plants (fusion or otherwise), the effectively complete electrification of the global commercial transport system, and a massive scaling of production direct carbon capture, leveraging the various aforementioned non-carbon emitting electricity sources to make it happen.

      Yep.

      Our experts estimate that the various societies on Earth have a 96% chance of solving the Great Filter using humanity’s great superpower of technological innovation, but paradoxically only a 3 to 7.5% chance of successfully implementing the necessary societal and political changes before complete extinction.

      Fusion is a marketing story to distract the attention. It is so difficult to realize a practical commercial fusion technology that it will not be available this century for sure.

      In any case as I explained in the other comment the root cause is overpopulation. Solving the energy problems might mitigate for a while the situation, but it will not solve the situation. Famines, conflicts and mass migration will happen anyway.
