Hey, you know that tipping point that everyone was talking about? Yea I think we’ve passed that

There was a hank green video about this a year back. Video link here, the tldr was that container ships used to use a type of fuel that was both bad for the environment but also really good at cloud seeding. More clouds shielded the oceans surface from the sun, artificially reducing its temperature. But in 2020 regulations made container ships move to a fuel that didnt seed clouds as much, so fewer clouds, higher temperature.
So i guess one potential take away from that, if its right, is that the temperatures are not “suddenly” getting worse, but rather have been artificially depressed and we are only now going to what it should be.
Actually it’s currently being looked at. The basic idea is to add sulfur to kerosine for airplanes to spray that into our atmosphere.
Bad side is it will cause acid rain, but the good side is that it will buy us a few decades that totally won’t be abused to speed even more CO2 in the air
And the millions of people who’ll die from the air pollution are, of course, of no consequence.
This has real ‘Operation Dark Storm’ vibes.

This is not a news article, it’s a picture of a graph.
In the interest of discussion here, I’ll leave it up this time.
Please report this to us earlier, or, if you think our rule about articles only is unfair, I would like to hear your thoughts on if this should be allowed in the future.
Id like to see documemtation for graphs that are quantifying something or apealing to emotion deeper than a meme.
Fucking January 6th!
HELP US
A lot of us want to make change but a lot of people are trying to stop it…
God, Gods, someone!
^help…
Hurricane season is going to be a fucking rollercoaster.
Some of You Guys are Alright, Don’t go to Florida next Autumn.
Are you doing anything in particular to try to stop it?
Writing to politicians that cover my area. Actively recycling and reusing things. Trying to control my personal footprint. Pushing for and using electric when possible or simply avoiding gas use.
I’m not sure what else I can do to make a more significant impact. I have thought about it for a while and I always come to the same conclusion that mega corporations and the like, should have accountability for what they create, rather than push it to the consumers who purchase.
Sun chips used to use biodegradable bags but stopped due to complaints of noise? I never experienced it so I’m not sure. But seems dumb.
As with any heavy lifting, a team makes the workload easier. Unsure how to press everyone to come together as we did with the ozone layer.
To be fair the chip bags were really loud…
I never got to experience them. Minor inconvenience for a better environment.
Well, I bet they didn’t lobby for fossil fuels at COP28.
Thank you kind internet person
I use Nitter Redirect (Firefox addon), but I do appreciate seeing a nitter link in the wild, thanks!
How can standard deviation be negative?
It isn’t, but some data are a negative multiple of standard deviation away from the mean.
Same question as in another subthread
It’s deviations from the mean, so if the deviation were “3” for example, values of 6, 3, 0, -3 and -6 would be 2, 1, 0, -1, and -2 deviations away from the central line, respectively.
Deviation != standard deviation
Standard deviation is square root of sums of squared deviations divided by number of samples. Only complex numbers can result in negative values when squared. Negative amout of samples makes even less sense.
Deviation from mean is
x - μ, standard deviation is this abomination:The standard deviation is not negative, that data was just that many standard deviations below the mean. Think “this data point is below the mean by 0.5 standard deviations” not “the standard deviation is 0.5”. They are using standard deviation as a unit rather than, say, degrees Celsius.
Then why yellow line doesn’t touch time axis? Function cannot always be bigger than its own mean. If there is point above mean, than there should be at least one point below mean. I’m assuming here mean is of temerature in that year.
The chart could stand for some clarification, but it looks like the mean and standard deviation refer to statistics covering all the years from 1982 through 2011. However, it does not explicitly state the dataset over which the standard deviation is calculated, but it seems reasonable to assume that the same aggregate cited for the mean is also the same aggregate used for the standard deviation.
Each line in the graph represents a single year of data. It’s kind of messy and only two of the years are actually labeled, 2023 and the partial data for 2024. So that bottom-most line represents some unspecified year that was consistently 1.5 to 2 standard deviations below the mean for the 30 year analysis.
The data is at https://climatereanalyzer.org/clim/sst_daily/json/oisst2.1_world2_sst_day.json, but alas, I’m too lazy to try to reproduce this sort of analysis to verify my guesses.
I will say it’s a peculiar approach and visualization. Including a subset of the data in the mean/standard deviation and then plotting the entire data. Also impossibly jumbled line graph visualizations of most years instead of something easier. I’d imagine you could convey the point with each year consolidated to a single data point and have a much easier to follow graph.
So, a little while ago climate change deniers used the fact of fluctuations in temperature throughout the year as a basis for a false claim that climate scientists were hiding the ‘real’ data in the less jumbly plots you suggest the use of. (And any sensible person would see the benefits of).
Whoever produced this is likely aware of those cynical and false claims, and decided they don’t want any risk the point they are making, being similarly undermined.
Thanks
Global sea temperature affects things like hurricane strength. Buckle up.
bro these seats are only equipped with 2 sigma buckles.
Fun fact you don’t need the to specify “recorded” history. The term history already takes that into account. Prehistoric refers to things before records were kept.
This is not a fact. This is a fun opinion, and it’s wrong.
Sure if you wanna be really nit picky but is a widely accepted opinion.
It’s recorded sea temperatures that allowed us to track changes like this over time that I was referring to. I know that wasn’t super clear by the title.
For the second recorded time in history…
