Abstract: Non-expert who uses scare quotes liberally ("scientific consensus", "data science") finds that he's the only one who's figured out that the world is, in fact, cooling.

Perhaps: "These plots of this dataset don't show extreme effect either way"

These plots, of these specific points of this dataset don't show extreme effect.

These are just arbitrary cities.

Not to mention that, most climate change stuff looks at the start of the industrial revolution, so a starting point of around 1920 is going to necessarily look a lot different.

All I can say as a 47 year old who lived most of his life in Germany is that the summers when I was a teen, so 30 years ago were considered hot when they were over 25°C. This year in May we had 32°C. Deny or criticize all you want cherries blossoming on Christmas in Berlin is NOT normal. And neither is the absence of snow in winter and mild temperatures. Those graphs don't impress me at all, because I remember what i…

I do think the global temperature is rising, but you can't say things like 'what I considered hot as a kid is different than what I now consider hot' and be taking seriously scientifically. Its an interesting anecdotal point but that's about it. I'm sure the data for where you grew up as a kid is available for the last 50 years, so get the data and give a real numbers to numbers comparison.

I have actually done this in terms of snow. I said to myself, it seems like there were bigger snow storms (in termps of inches of snow) when I was a kid. so I got the data to verify it, and yes, not only were the snow as a kid much higher, they were also historical high - a couple record snowfalls when I was a kid. The point of this story isn't meant to tie anything to climate change, but rather be more curious and get data to back up your thoughts.

You can notice ~10cm difference in sea level? https://sealevel.nasa.gov/faq/13/how-long-have-sea-levels-be...

You don't notice the vertical differences, you notice the horizontal distances (land that is covered which was not previously covered).

What is the delta-T in the graphs? I took that to mean delta from the average temperature, but then some of the graphs don't make sense. For instance, the fitted line for delta-T in the Stockholm data is entirely < 0, which wouldn't make sense if 0 represented the average temperature.

"The global median temperature (of the entire dataset) is uniformly subtracted from every data point, to keep things relative to an arbitrary x-axis of 0."

This is just a bunch of plots with no effort to engage with the existing literature and study. Frankly, it is a waste of time trying to draw conclusions about global warming from this.

What if existing literature and study is somewhat biased by 'green' funding?
