| What's interesting to me is that almost all models underestimated the ocean temperature. We are entering uncharted waters and I fear that at some point we will get an extreme extreme weather event and the worse thing is that we won't see it coming. |

| That should be the scary part. We know how El Niño affects world's weather, but it is also a symptom of how much heat the ocean is absorbing. That core problem won't end this year or the next one, and it will keep disrupting global climate. And with it, agriculture, settlements, economy and civilization as we know it. And the scariest part is what we do about it. Keep doing activities that rise global temperature and power up positive feedback loops, weakening or abolishing climate policies, and when things start to feel urgent will try things by the fast way with unclear outcomes. |

Not at the global, continental, local or individual level. FFS, there are idiots proudly rolling coal. - Leadership - in the rare places on earth where it is somewhat accountable - reflects this lack of consensus. - Acknowledging the problem does not equal acting even on an individual level. - There's lots of cognitive dissonance. Why am I even flying to the other side of the world next week? We are cooked. Not so much us old farts, but the children. | |

| Well, we can see it coming, but we are doing very little about |
| |
| ▲ | CGMthrowaway 19 minutes ago | parent | next [-] | | We are doing a lot. Almost 90% of electricity capacity added last year was renewables. Nearly 1 in 3 cars sold are now EVs. The world is spending over $2 trillion every year on low‑carbon energy investment. Solar and wind have already avoided more than 2 gigatons of C02 being added to the atmosphere. In the US, the IRA will drop emissions 40% to below 2005 levels. What do you mean we are doing very little? | | |

| ▲ | inigyou 2 hours ago | parent | prev | next [-] | | We've been seeing our own certain destruction from climate change coming since the 70s. The 1870s. We had two entire lifetimes to do something about it, we didn't. Except those guys throwing soup at the fossil fuel HQs. They did a little. | | | |
| ▲ | windexh8er 2 hours ago | parent | prev [-] | | We're building more data centers for a technology that's ramping global warming even faster. Water consumption, heat generation and tons and tons of CO2 emitting concrete to house these things. So we're doing something, but those things are counterproductive to our planet's general well being. Apparently billionaires don't need an inhabitable Earth to live on. | | |
| ▲ | asats an hour ago | parent | next [-] | | Yeah, data-centers are definitely the worst thing happening to the planet. You got your priorities straight. AI data centers are what, half a percent of the world electricity consumption, if that, and an even smaller fraction of the total energy? | | |
| ▲ | dredmorbius an hour ago | parent [-] | | Growth trend matters more than absolute present value. Data centres generally had been seeing energy use growing at 12% annually, or with a doubling time of 5.8 years (about 5 years 10 months). AI is accelerating that trend. In the United States, power consumption by data centres is on course to account for almost half of the growth in electricity demand between now and 2030. Driven by AI use, the US economy is set to consume more electricity in 2030 for processing data than for manufacturing all energy-intensive goods combined, including aluminium, steel, cement and chemicals. In advanced economies more broadly, data centres are projected to drive more than 20% of the growth in electricity demand between now and 2030, putting the power sector in those economies back on a growth footing after years of stagnating or declining demand in many of them. <https://www.iea.org/news/ai-is-set-to-drive-surging-electric...> | | |

| Due to the widespread idea that climate prediction has been predicting doom and gloom all the time, and has always been wrong about it, I have been entertaining myself by revisiting old climate predictions from 20 years ago. I can highly recommend it. I mean, predicting the climate must be one of the hardest numerical simulations you can run. Climate models are famously incomplete. But the results turned out to be way more accurate than I would have thought. That's some impressive modeling, and I would assume that models have only improved since then. The most chilling thing (and not in a good way) about it is that popular science type repotrs for the general public usually indicate an interval between a good case and a bad case, with a nice line in between. In retrospect we have been pretty much perfectly tracking the bad case line ever since. |

| Once I listened to a podcast about the holodomor, a famine caused by Stalin and affected Ukrainians mostly. In the end they were forced to eat their children as they were so desperate for food. The suffering was untold, but real, it happened, and that kind of thing can and will happen again if we're not extra extra careful. We're pushing ourselves into absolutely untold suffering the longer do nothing. I truly fear a famine like that and the more we go down this road, the closer we're getting. Obviously its too late to avoid the worst, the only hope we have is to collectively cooperate to help each other get through it. Not sure that will happen but I believe that's the only way through. |
