A book came out in August 2024 called "Soda Science: Making the World Safe for Coca-Cola," by Susan Greenhalgh. She's a professor (emeritus) at Harvard. The book is a history. It shows how the Coca-Cola Company turned to "science" when the company was beset by the obesity crisis of the 1990s and health advocates were calling for, among other things, soda taxes.

Coca-Cola "mobilized allies in academia to create a soda-defense science that would protect profits by advocating exercise, not dietary restraint, as the priority solution to obesity." It was a successful campaign and did particularly well in the Far East. "In China, this distorted science has left its mark not just on national obesity policies but on the apparatus for managing chronic disease generally."

Point being, the science that Coca-Cola propagated is entirely legitimate. But that science itself does not tell the whole, obvious truth, which is that there is certainly a correlation in a society between obesity rates and overall sugar-soda consumption rates. "Coke’s research isn’t fake science, Greenhalgh argues; it was real science, conducted by real and eminent scientists, but distorted by its aim."

"Trust the science" can thus be a dangerous call to arms. Here's the book, if anybody's interested. https://press.uchicago.edu/ucp/books/book/chicago/S/bo221451...

I wonder how much of this same kind of manipulation/distortion is going on when we are told to "trust the science" with regard to climate change? The pressure to ignore or minimise inconvenient facts would be overwhelming (career at stake situation).

what's the bellwether for climate change? Rising temperatures, rising CO2 concentrations?

There's strong evidence there actually isn't warming going on. The "warming trend" may be due to the temperature sensor locations. Originally the sensors were put in remote, rural, unpopulated and unused locations (ideally!). As communities grew... you understand that the sensors now are no longer rural, remote, unpopulated areas. What happens to the air in a city? If you're unsure, "urban heat island". This is extremely localized "weather" - the sort of thing that i've been yelled at "IS NOT CLIMATE".

I'm only going to link 1 thing here, because doing this sort of thing on my lifelong handle has never done me any favors:

Ok, arctic sea ice.

Ice exists at temperature below 0C or 32F at 1atm AND at system energy levels below the enthalpy of melting for liquid water, or latent heat for this first order phase change.

Thermodynamics uses temperature and pressure to explain system energy of molecules for liquid vapor solid phase systems. Latent heat is the esoteric part of this phenomenon because it requires a scientific education to understand calculus and work. Understandably, everyone can grasp temperature.

I think your comment is a perfect example of misdirection and people using “data driven methods” to attack a “first principles” explanation of physical phenomena.

Here’s a link because that gives my idea more weight.

Computer people talk about scientific methods and their “home lab” stuff, ai and inherent structure of data then absolutely fall for the facebook-grade-misinformation arguments to not trust something that is too mainstream. Jfc

you mean the sea ice, that had the highest extent in 20 years this year? Or a different sea ice, perhaps the one they always trot out around January? you know, when it's summer in the southern hemisphere?

The sea ice data isn't 1:1 with the seasons, so "data scientists" and "climate scientists" pick the cutoff date that makes the best headline. Even this year they were saying the ice was lower than average, but they cutoff 3+ weeks early, the ice was above average a few weeks later.

Besides all this, i am unsure if you're supportive or not of what i said.

I admit data collection is imperfect, especially looking back 200 years. But to attack a fairly sound hypothesis that is multi factorially demonstrated in physical geological behavior, I wholeheartedly disagree with.

Just because US weather stations in the 70’s were more rural than urban does not in itself gives credence to the idea that climate change/warming/ greenhouse gases is a nonissue or somehow a totally misunderstood non-warming phenomenon. Even a climate that tended to one mean value zero standard deviation throughout the year would be devastating coming from our current temporal and geographical distribution.

Your point about weather stations is a technical detail in data collection while there are several other corroborating methods indicating a warming ocean and atmosphere, albeit not geographically uniformly distributed. But you have this gotcha fact about weather stations ambient baseline temp vs some platonic ideal temp that reflects what’s going on in the abstract notion of a climate.

The sea ice has satellite photo analysis (area) dating to 70’s or 80’s with daily or weekly granularity.

I cannot convince a climate change denier or skeptic but am leaving that comment and this one hoping that observers don’t just take your initial counter-fact to be a valid falsifying argument.

As everyone says weather is not the climate, spurious yearly data do not nullify long form trends, and I’d just look at low pass filtered or line fit or yearly average of granular image data to argue that there is a time localize trend since the 80’s consistent with a warming ocean.

I disagree with you I think you used logical fallacies to misdirect and cause skepticism about something that is fairly corroborated and the debate needs to focus on mitigation or investment or policy changes.

see my links at https://news.ycombinator.com/item?id=42189475 if you like, it adds to the fact that sea ice this year was higher than the prior 20 years; because 2002 was higher. Furthermore, sea ice in that detail only goes back to 1979, and we're talking about a literal ~6% decrease in that period (at least prior to 2024!) - which, 6% in 40 years, we don't really know enough about it, considering that ice has been there for, oh, let's ballpark at a million years as it is today, actually it's been growing probably for 20 million years, but that's irrelevant.

The atlantic was colder this year than normal. I know a lot of media people were saying "hot as bathwater" and "perfect fixins for storms and climate issues" but also this year they said that the AMOC may be ending and northern europe will be igloo central. Guess how long we've been studying that? 20 years. TWENTY.

call me old fashioned, but "models" made in the last few decades on data we've only been realistically collecting in a "rigorous" fashion for 20-40 years don't impress me, especially with stuff like Judd et al., Science 385, 1316 (2024) coming out in the past couple months showing that the global temps over the last 485mm years mean all this "anthropogenic climate change" stuff is hilariously wrong-headed.

Now, hear me out for one second. I am environmentally conscious, i try not to pollute. i rarely drive, i never fly, i tried solar but it didn't work very well in my location. I care about people not damaging the planet we live on. What i can't abide is pointing at models (what's the M in LLM stand for? does SD have models? how about the music generation stuff, those models?) and extracting currency from everyone to solve a problem that moves when you stare at it.

i don't expect to convince anyone here. It's not my calling in life to go debate this in public. Do what you want. Just don't tell me i have to do something else because "the model says so", alright?

there's a joke "apparently the police have been beating up black people like hotcakes" that was unknown until consumer camcorders and cameras were widespread. We now have billions and billions of sensors on this planet, and we can all do our duty to VERIFY that what the model says is accurate, and what the model was fed was accurate. You ever researched when the first "accurate" thermometer was developed/patented?
