- disgruntledphd2 2y agoFor you, in one place (or some subset of places). This article is talking about something quite different to your (or my) experience.
- fredrikholm 2y agoWhich was?

- jjulius 2y ago>It wasn't even the hottest in my lifetime. Fun fact: It could have been cooler than the hottest summer in your region in your lifetime, while also being the hottest summer, globally, in two thousand years. And at the same time, too! Isn't that neat!? :D
- bobosha 2y ago..and 2024 will beat that handily ={
- kachapopopow 2y agoWhy is this downvoted when the oceans warmed up nearly an entire degree after we stopped dumping sulfur into them? It is very likely that 2024 will be the hottest summer in two thousand years.

- amelius 2y agoAll those nVidia cards produce a lot of heat.
- louwrentius 2y agoThe AI hype isn’t really helping.
- ilikehurdles 2y agoChina is responsible for 70% of new coal power plant construction, meanwhile greenhouse gas output in the US (whether measured per capital, against income, against gdp, or against fuel consumption) has been dropping for almost 30 years. The ai hype could help if it means increasing automation, as compute is cheaper than commute.
- M95D 2y ago> The ai hype could help if it means increasing automation, as compute is cheaper than commute. Don't compare AI with commute. Compare AI with (human) remote work. AI will never be cheaper than remote work and AI can't replace any work that can't be remote work.
- postalrat 2y agoUnless it it's more than hype.

- jjulius 2y agoFriendly reminder that you can still show a trend over the past 2,000 years, even if the past "~20" don't show the same.

- ilikehurdles 2y agoThis seems like a different dataset than the flagged comment referenced? Does anyone know what they were talking about?

- abathur 2y agoThey mentioned "NOAA's USHCN reference network of well sited thermometers" (I opened a search to go figure out what they mean, but work interceded.)
- ForHackernews 2y agoIt's going to keep getting worse for the rest of our lives, and then even worse for our children and grandchildren: https://arewestillfucked.com/ https://arewestillfucked.com/ It's a tragedy but at some point it stops being news.
- input_sh 2y agoThe thing that truly made me realise just how fucked we are is when the Guardian sent out a survey to the scientists behind the IPCC report. About half of them responded: > 77% of respondents believe global temperatures will reach at least 2.5C above preindustrial levels, a devastating degree of heating; > almost half – 42% – think it will be more than 3C; > only 6% think the 1.5C limit will be achieved. https://www.theguardian.com/environment/ng-interactive/2024/may/08/hopeless-and-broken-why-the-worlds-top-climate-scientists-are-in-despair https://www.theguardian.com/environment/ng-interactive/2024/...

- BillFranklin 2y agoPSA to the hardware engineers on here -- Y Combinator is actively looking for founders starting climate tech companies: https://www.ycombinator.com/rfs#climate-tech https://www.ycombinator.com/rfs#climate-tech
- BillFranklin 2y agoAlso well worth reading -- https://www.institute.global/insights/climate-and-energy/reimagining-the-uks-net-zero-strategy https://www.institute.global/insights/climate-and-energy/rei... Tl;dr = Climate change is best addressed by producing technology that makes things more efficient and/or that helps the developing world decarbonise. If anyone is working on something gamechanging please hit me up -- I'm happy to help out on the dev / infra side pro bono.
- lucianbr 2y ago> The financial opportunity of building in this space is massive: an estimated $3-10 trillion in EBITDA will be up for grabs. Recent legislation will also significantly accelerate the existing market trends. Yeah, I don't think these will be part of the solution. We're not going to get out of this by making more money. Trying to make more money is how we got here. I recently read some opinions about carbon credits for example, and boy does it look like it's just a scam to take money from governments into private pockets, while at best doing greenwashing.
- BillFranklin 2y ago> We're not going to get out of this by making more money. I absolutely think we are going to get out of this by making money. The incentives preventing action on climate change are not moral/ethical, but economic. Countries and individuals use fossil fuels because they are cheaper, and are unwilling to make decisions that put them in a worse position relative to others. While de-growth naively sounds appealing, the results are horrendous – countries with approx. the same GDP that they had 20 years ago are not places you would want to move to. You might also point to the ozone layer issue in the late 80s and argue an accord will fix our current problem, but fossil fuels are far more fundamental to our way of life than CFCs were.
- Pelam 2y agoBut economy, china, developing nations, my personal right to consumption, factor x is making this metric seem worse than it should be, another political thing is more important, technological solution Y will save us, technological solution Z won't help or has flaws... endless list of arguments that derail discussion and end up in effective inaction. Humanity's capacity to handle an slow creeping existential threat appears to be very bad. Especially when preventing it requires simply stopping / doing less some of the things we are doing. Apparently the production of greenhouse gasses has gone up in past years regardless of the negotiations aimed at reducing them. I suspect geoengineering is where this will end up when things start to get really bad. Question, what are the most viable / cost effective / low risk geoengineering tools?
- rlili 2y agoI see it more like: > Major lobbying companies' shareholders' interest in handling an slow creeping existential threat appears to be very bad.
- Filligree 2y ago> Question, what are the most viable / cost effective / low risk geoengineering tools? Inject sulphur dioxide into the stratosphere. This can be done by adding it to airplane fuel. We have a good idea of the consequences, as ships did the ~same thing (less effectively) until recently—they're now filtering it into the oceans instead.
- kachapopopow 2y agoAfter we stopped dumping sulfur into the oceans the average temperature went up nearly an entire degree![1] This will heavily affect the size of cyclones and other weather related disasters (not just heatwaves). 2024 might finally make people realize that the end is near once parts of the world in developed countries start to be slowly wiped off the map due to non stop natural disaster events.

- chiefalchemist 2y agoSimply (and obvious) question: Of the recent climate change, how much is human-made and how much is natural? 2000 yrs ago, the world population was a fraction of what it is now. Tbere was no mass burning of fossil fuels. And yet the temps were at record highs. Do we have enough reliable data to judge the climate properly?
- silverquiet 2y agoIf it's an obvious question to you, don't you think that climate scientists who have been looking into this for going on a century might also have thought of it and perhaps written about it?
- chiefalchemist 2y agoIf they have... 1) You could have provided a link to two, yes? 2) The Media - and its scientist (?) pundits - would ease up on the "this is absolutely 100% human-made" narrative. 3) People who have suggested that maybe it's not "absolutely 100% human-made" would not be ridiculed, marginalized, canceled, etc. So if you can help out with any of these, it would be appreciated, sincerely. p.s. And per the article, the climate data that was being used prior, was incomplete, unreliable, and too small a sample size. And yet how many leaders and scientists have been basing big stroke ideas on that? We can't demand The Science, and then cherry pick bullshit because it perpetuates a narrative. Or can we??
- silverquiet 2y agoI'd rather not. Frankly, it's grim enough that I don't really recommend doing the research on your own, and just staying ignorant if you can.
- chiefalchemist 2y agoFrankly, that's weak. We don't come to HN to breathe sand. We come here to seek truth.
- post_break 2y agoIt's been hotter on this planet every year since the year I was born.
- fho 2y agoThis ... ... since 30 years (of not longer) it was the "hottest year of all times" some where on Germany. One or two years in a row? Random chance ... Every, single, year for 30 years? Yeah something is definitely wrong here.
