    To understand where climate change is heading, we have to look at the planet’s distant past and appreciate the disturbing uniqueness of our situation, says Bill McGuire

      Maybe if we build maaaaany more ai data centers we can ask ai for a solution. I mean, they are a major cause for the exponential pollution but they might have an answer and they can create boob pictures.

          And the twats in the US “government” plan on using satellites to beam sunlight down at night, because we definitely need more fucking hot…

          With luck this will get scrapped or they’ll get sued. Seems like a stupid ass idea (imagine that).

              It’s a stupid idea, but it also won’t make a difference. Mirrors aren’t going to increase the total amount of radiation hitting the Earth, in an amount that can actually make any difference.

              The surface area of the Earth is 510,000,000 square kilometers. How much surface area of mirrors can they even fit in a sun synchronous orbit at the edge of dusk or dawn, where the satellite is catching sunlight but not casting a shadow over a part of Earth? Even if they put up a million satellites with mirrors that are 324 square meters that’s only 324 million square meters, or 324 square kilometers. In other words, their most optimistic projection involves increasing sunlight by about 0.00006%.

              It’s a disaster for astronomy, and for ecological balance for any affected wildlife, but won’t actually heat up the Earth.

              I’m just gonna cross post this here.

              We have the means to end every form of inequality out there. We would just have to come together as world to make it happen. But no. We’re basically monkeys with nukes.

              Which is why, as a species, we deserve everything coming our way.

                                I’m truly in awe of nature. Gaia as a living being has gotten a virus. And though lots of other species are affected and some have gone or will go extinct because of this, the species that are going to see the biggest % culling of their numbers and those who survive will have to adapt to most of all species is the exact species gaia’s trying to teach a lesson - if not outright get rid of.

                                    The species who will suffer the most and go extinct has had nothing to do with this. The climate change is all on humans, but most other species will suffer and die along with us. There are species going extinct right this moment on account of climate change.

                                    Meanwhile it is unlikely humans will go extinct, because we are much more capable of adapting than all those highly specialised species who suffers the most.

                                      Gaia sounds like an abusive parent in that case. Last time I checked it was her and her affair with evolution that threw us into the picture.

                                            Ha, that’s an interesting look on it.

                                            What I got from seeing this thunderous stuborn belief in religion and first and second comings, it that perhaps we are a GMO of apes by some ET species reprogrammed for mining and grabbing (accidentally discovering caffeine and inventing capitalism along the way) some rare resources or for terraforming for a different species for when they come again (this second coming shit I keep hearing about, which seems reason enough to justify the Palestian genocide and now litterally lighting the world on fire).

                                            In either scenario, humans wont be aren’t the beneficiaries.

                                              This is the crux of it, and not enough emphasis is placed on this. It is the unprecedented rate of warming more than the total amount that is of greatest concern if you’ve studied any paleoclimatology and seen how long it takes for natural systems to re-establish in a new climate regime.

                                              There has been a lot of study on how the transition to the current interglacial climate affected the biogeography, and you can see how forests, coral reefs, etc. were still trying to relocate several thousands of years into it. Now, of course, they’re screwed, and we have mass forest fires and the like because they have no hope of adapting anymore.

                                                Humans tend to believe we are unbeatable. In reality, in 100, 200 years we may have disappeared completely. This has happened to many other species.

                                                    Humans are the most adaptable species in the history of the planet. Humans will survive, but it will be at MUCH lower numbers. And it won’t be people in bunkers.

                                                        I’d say horseshoe crabs still beat us in terms of adaptability, they’ve been around since the Triassic (>250 million years ago).

                                                              sponges and cnidarians beat them to it, 500-600million years. and jellyfish have been exploding in numbers all over due to temperature rises, generally more tolerant to pollution than fishes, and lack of too many predators.

                                                                  Similarly I can say that Reptiles beat horseshoe crabs since they’ve been around at least ~50 million years longer than the latter, but that wouldn’t really be a fair comparison because they encompass far more species than just horseshoe crabs. Regarding lasting a long time evolutionarily while staying relatively undiversified, horseshoe crabs are still uniquely notable. They aren’t called living fossils for nothing.

It is much more likely to be the supernatural equivalent of a 10-year old pulling the wings off of flies and cooking ants with a magnifying glass.

When all hope is lost, it would be handy to have an omnipotent being on your side. So the idea of one existing would be comforting, regardless of the actual existence.

About 1C of total warming.  Second chart:  about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability.  Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases.  About 0.5C of cooling with large error bars from SO2.
