World ocean temperatures in 2021 were the hottest ever recorded
- rossipedia 5y agoThis is fine
- sparky_ 5y agoI see you're being downvoted; I suspect OP is sarcastically referring to the "dog in a burning kitchen" meme..
- rossipedia 5y agoYou're correct. I erroneously thought I didn't need the /s, but alas... I was mistaken.
- hwbehrens 5y agoI downvoted your parent comment not because I didn't catch your meaning, but because I didn't think it contributed meaningfully to the conversation (basically, a throw-away 'ha ha' comment). Elaborating on your perspective on the situation, sharing how it's affected your behavior or though processes, or engaging others in discussion would have produced a more substantive contribution. I am very sensitive to HN sliding into a 'Reddit, but for nerds' situation where facile comments dominate the conversation and the signal-to-noise ratio is unbearably low. Looking at your other comments, in general you do a pretty good job of holding back the tide -- please don't take this as a general comment against you, but more as a signpost for others.
- Datenstrom 5y agoDon't look up
- matsemann 5y agoForecasts for +10C in Oslo Norway the next days, possibly melting all the snow and ruining skiing in the forests during lockdown, my best reason to go outside at the moment..
- horstmeyer 5y agoToo bad you can't go skiing, but I'm a bit more worried about plant and wildlife that "thinks" it's spring and then will get killed when it gets cold again later.
- matsemann 5y agoOf course. And I also know a single instance isn't proof of climate change. But I wanted to point out / rant about how the winters have changed over time here. It's sad. And summers hotter than ever. Have had to buy AC, as if we're in Southern Europe.
- dragonsky67 5y agoJust interested in what temperatures have risen to that you need an AC? I also understand that buildings in normally colder climates are optimised to keep warm so that if things get hotter in general they are not going to cope well so an AC may well be necessary at temperatures that in other regions would be considered relatively cool.
- magicalhippo 5y agoIt can get above 30C here[1][2], which is pretty hot for us. As you say, buildings are well insulated for the winter which means that the walls retains a lot of heat into the night once they've been baking for several days. Keep in mind the sun goes down at around 11pm, so it doesn't really get cold outside until well past midnight. In my home, that means it can be 25C inside for hours after bedtime unless I use AC and keep the interior cold during the day. One could get used to 25C I suppose, problem is it's just for a few weeks at a time, then it goes back down. So you never really get used to it.

- the-dude 5y agoSince 1940. Or 1958. Or is it 1995? Why does the graph have 2 colors? Why is 1995 'zero'?
- jvanderbot 5y agoIt's relative to 1981-2010 baseline. Negative is lower, positive is higher. In 1995, presumably, it was also the average temperature for the 1981-2010 time. The two colors are negative and positive, a potentially unimportant dramatization. Clarifying based on what I understood: Data from 1940-today show that the period from 1985-today had 8x more heat added than the period from 1958-1985, and that each decade since 1958 has increased in temperature.
- avereveard 5y agoBecause ever recorded is a code word for only recently - sea surface average is about around the medieval climate optimum and under the roman age warming period. Not to say climate is not warming up, but news reels always go for the most sensationalistic take they have available because that sell, while more nuanced takes tend to be buried under pressure from the ministry of truth to control the message, as they believe us to be simpletons.
- viggity 5y agoChart has baseline at ~1995. They say we reached 200 zettajoules around 2019. 200 zettajoules => 2.0e23 J * 4.184 J/cal => 8.36e+23 calories They say this is the energy absorbed by top 2000 meters of the oceans. There are 84.8 million sq km of ocean. 2000m * 84.8e6 => 1.69e20 liters of water. 1000 calorie to warm 1L of water by 1 deg C. 1.69e20 L / 8.36e23 cal => warmed by 0.2 deg C since 1995.
- idealmedtech 5y agoThat's alarmingly fast.
- glial 5y agoIf my calculations are correct, that's the equivalent of 52 billion Hiroshima bombs.
- MatteoFrigo 5y agoDon't you want to divide J by (J/cal) to get cal (as opposed to multiply)? 2.0e23J = 4.78e+22 cal

- mrjangles 5y agoNot only does science show the current temperatures are getting hotter than ever. We now know the past 50 years was colder than we ever thought. With new advanced scientific techniques, we now have a much better idea what the temperature was 50 years ago than they did 50 years ago. It should be kept in mind, these new temperatures measured now are not breaking records compared to the temperatures measure 50 years ago, but rather to the modified and corrected temperatures of 50 years ago. Here is a great little collection showing how the temperature records change over time. https://stevengoddard.wordpress.com/alterations-to-climate-data/ https://stevengoddard.wordpress.com/alterations-to-climate-d...
- matsemann 5y agoI don't understand this. How / why is near-historic data being changed? Got any more material on this?
- hagbard_c 5y agoThe data is being "corrected" to "take away errors", this is clearly visible as well as explained by Heller in his many videos on the subject. Another issue is that the measuring network has notably shrunk in size in the last decades with the measurements from locations which have been taken out replaced by interpolated data. Heller claims that "uncorrected" historical data shows that the average temperature in the 30's was higher than it is today and that this is the reason for the "corrections" - simply to make the data fit the narrative. Looking at actual historical data seems to corroborate his claim of the records being "corrected", US state and territory temperature extremes [1] also show a tendency to have the highs somewhere in the 30's (23 states) with 1936 as the hottest year in 13 states. These are "uncorrected" temperature records. [1] https://en.wikipedia.org/wiki/U.S._state_and_territory_temperature_extremes https://en.wikipedia.org/wiki/U.S._state_and_territory_tempe...
- mikeyouse 5y agoThere’s not much to understand— some crank thinks he found the dark secret of climate scientists. His blog is the typical nutter mishmash of mindless conspiracy theories from “putting mRNA In the food supply” (https://realclimatescience.com/2022/01/putting-mrna-in-the-food-supply/ https://realclimatescience.com/2022/01/putting-mrna-in-the-f...) to antivaxxer garbage (https://realclimatescience.com/2022/01/study-shows-covid-vaccines-make-things-worse/ https://realclimatescience.com/2022/01/study-shows-covid-vac...) to big pharma conspiracies (https://realclimatescience.com/2022/01/herding-the-sheeple-for-big-pharma/ https://realclimatescience.com/2022/01/herding-the-sheeple-f...) to all manner of climate conspiracy theories. He and everything he touches can be safely ignored.
- KETpXDDzR 5y agoI have the feeling that many people (especially politicians) think that global warming is a linear process. It's not. It might even be exponential since some sources for climate-warming are affected by warmer climate. For example, melting ice that reflects sunlight back to space [https://arcticwwf.org/places/last-ice-area/ https://arcticwwf.org/places/last-ice-area/]. I'm thinking about choosing a new place to live right now. Climate change is a big factor for that.
- irrational 5y agoPersonally I would not buy property south of the 45th parallel anymore (in the northern hemisphere). Even north of that we have seen shockingly high temperatures. Anything south of that will become a hellscape within our lifetime.
- sumedh 5y ago> Personally I would not buy property south of the 45th parallel anymore Obama bought a property in Martha's Vineyard, why would a former President with all the knowledge about global warming buy it?
- arn 5y agoCause he’s rich and can afford it regardless what happens. Why would you pay for ice at a convenience store when you could make it yourself at home.
- smm11 5y agoLots of funky fish found lurking off the LA coast these days.
- willio58 5y agoIs anyone on HN reconsidering having children because of climate change? Recently I've had a big shift myself on this topic, probably influenced by not many women my age (younger than 30) having any interest in bringing a child into a world where they could potentially suffer real physical danger due to climate change.
- jvanderbot 5y agoWell, the birds aren't going to fix climate change. I can't speak for the women you know, but the women I know in their 20s-30s tell me they aren't thinking about children at all probably thanks to the empowerment of women of the last 100 years. Over my life, I've heard all kinds of excuses for all people to not consider children until they are in their late 30s or 40s, then it's a rush. I did the same. I'm not sure it's climate change.
- adamrezich 5y agoyeah I've noticed that the antinatalists never seem to be saying, "man, I really really want to have kids, it's one of if not the most important driving forces in my life... but the threat of climate change looms ever-present, so it would be irresponsible to bring my heirs into this fallen Earth!"—it usually if not always seems to be a post-hoc excuse for a decision they've already made, or at the very least, a justification to move off the middle of the fence toward "no" instead of "yes." if anyone knows of anyone who's written something that contradicts this I would love to read it.
- KennyBlanken 5y agoMost people I know are not having children because they don't have the economic stability to do so. Housing, individual low/middle income tax burden, cost of living, stagnated wages over the last several decades for all but the top 25%.
- jvanderbot 5y agoLet me tell you one thing I've learned: There's never ever a good time to have children.
- propogandist 5y agoWe should start by working to keep the ocean clean, then worry about the temperature of the polluted water. Why is there more interest in controlling the temperature vs the pollution itself? consumerism needs to change for temperature to change
- Flashtoo 5y agoThese are different problems that both need to be addressed as soon as possible, but for different reasons. Having said that, runaway global warming seems like the more pressing existential threat to me.
- BeKindAndLearn 5y agoClimate change may very well be an extinction level event. Plastic in the ocean is not.
- missedthecue 5y agoReminder that according to the IPCC there is literally no scenario where the human race is worse off in 2100 than we are now, even if we do nothing about climate change and continue to use fossil fuels. "Extinction event" narratives are not grounded in reality or backed by the science. https://en.m.wikipedia.org/wiki/Shared_Socioeconomic_Pathways https://en.m.wikipedia.org/wiki/Shared_Socioeconomic_Pathway...
- propogandist 5y agowe can't accurately predict tomorrows weather or even trajectories of hurricanes, but lets go with this idea that the modeled weather forecast that's a decade out is realistic What will you do to drive change?
- mkoubaa 5y agoAt this point "World ocean temperatures this year were not the hott st ever recorded would be front page news"
- mandmandam 5y agoI'd like to remind the HN community, some of whom are rather quick to defend the corporate matrix, that fossil fuel companies saw this coming in the 70s and covered it up. And they had broad, deep-pocketed support. Government subsidized them, and protected them after their oil spills. Media ran Exxon and Chevron's greenwashing ads, Police beat up protesters, going so far as to infiltrate their groups, seduce their leaders, and have entire fake marriages with them all to keep tabs on them. Judges sent those protesters to jail - Steven Donziger ought to be a household name, for a recent example. The military invaded countries illegally for them. And not a single comment here so far as I can tell is putting any of them on the hook for this ongoing atrocity.
- refurb 5y agoAnyone who drove a car or took a flight or bought things they didn’t need contributed too. Don’t try and weasel out of it.
- mandmandam 5y agoDon't do that man. The oceans are growing acidic, countless species are being lost forever. We could literally all die because of this. Blaming me for my commercial air travel while Chevron can imprison a lawyer for fighting against them is beyond fallacy, and well past what I can describe in polite terms. Do you have family in the oil biz or something? Why would you do this?
- refurb 5y agoJust because Chevron did something wrong doesn't mean you get off scott-free. Chevron can't fix global warming on their own, it takes everyone, including you.
- roughly 5y agoChevron damn near could. I bear the blame for climate change along with Chevron just like I own stocks along with Jeff Bezos.
- xwdv 5y agoEvery year, it seems like we get closer and closer to the end. One day, temperatures will be so hot, and they will not go down. They will only continue to rise, people being kept alive by AC. Then the power grids will fail, and AC won't work, and people will just pass out from heat strokes and die off. And the world will be left with only the few who can withstand the increasing temperatures. And then the temperature will increase even more, and those too will die, or starve from nothing to eat. Bare shelves, dead crops. This is how the end will be. Crime will become rampant as rising temperatures make people more violent and people take what they need to survive by force. Grim.
- kilbuz 5y agoYour first sentence is a tautology. We are by definition closer to the end than ever before, and always will be.
- betwixthewires 5y agoI don't know if this comment is serious or not, but if so, it is hyperbolic nonsense. Not to say there's no warming, obviously there is, or to say it won't have detrimental effects, but it's people saying things like this that give deniers ammo to call it a doomsday cult. If you truly believe what you've just said, you need to take a step out of your own head and unbiasedly self reflect and examine the merit of your worldview for a minute.
- xwdv 5y agoWhy would it be hyperbolic? What exactly do you think happens when temperatures keep rising to unbearable levels? Keep cranking up the AC? What about the crops that feed the animals we eat to survive? What about the dwindling oceans we farm sea food from?
- richk449 5y agoDwindling oceans? I thought that the sea levels are rising?
- betwixthewires 5y agoHonestly, I'm beginning to think that constantly ringing the alarm bells desensitizes people. These sorts of articles year after year are creating people that either don't care or don't think their life matters enough to care, considering "life won't be worth living in 20 years anyways." So I'm not sure what there is to be done, it's like a catch 22. Tell people nothing and they leave it out of their minds, tell them about it and they get desensitized, maybe mobilizing the people is doomed to fail from the start and this thing is irreversible.
- tzs 5y ago2021 also continued the streak of consecutive months with the global average surface temperature above the 20th century average. November 2021 was the 443rd consecutive such month [1]. [1] https://www.ncdc.noaa.gov/sotc/global/202111 https://www.ncdc.noaa.gov/sotc/global/202111
- egberts1 5y agoKeeping adding more temperature reading stations in cities and suburbans and you too will get record-breaking heat trends.
- drukenemo 5y agoNot to mention the fact that urbanization has been progressing at large worldwide for the past decades. And urban areas are obviously warmer.
- egberts1 5y agolet us ignore the rising means when adding more clusters of temperature reading stations in urbanized areas.
- roughly 5y agoYes, all of those cities and suburbs in the Indian Ocean, that’s what’s creating the trend described in this article.
