**Decrease in industrial production in 2024**

"_In nominal terms, the EU’s value of sold production went down from €5 975 billion in 2023 to €5 860 billion in 2024, indicating a 1.9% decrease._"

Looking forward to giving a 4-hour workshop on #dataviz at the First Summer School on Linguistic Creativity in Bielefeld tomorrow! #Vorfreude

UPDATE

That was a lot of fun and we manage to cover a lot in four hours! The slides can be found here (but please note that they are not intended as self-learning materials): https://elenlefoll.quarto.pub/2025-bielefeld-dataviz and the practical #ggplot2 part was based on Chapter 10 of my in-progress textbook: https://elenlefoll.github.io/RstatsTextbook/10_Dataviz.html.

With data visualization, it's the same as with dating - looks may matter, but what's most important is communication.

Here I compare charts for the Stanford dataset "How Couples Meet and Stay Together" - from the original academic paper, The Economist, Statista, and crucially, from Redditors and TikTokers. We'll see how different media shape the way data is presented.

As the cherry on top, we'll explore what we can do with AI to tweak aesthetic style to match our narrative - and the medium

Interesting.

"Liu worked with professors at Princeton to test how people responded to two different graphs. One showed winter temperatures of a fictional town gradually rising over time, while the other presented the same warming trend in a black-or-white manner: The lake either froze in any given year, or it didn’t. People who saw the second chart perceived climate change as causing more abrupt changes."

New server, new #introduction:

Hi! I'm Eric! I'm a scientific programmer & educator who writes mostly code. I currently work part time at #UniversityOfArizona where I help researchers by making R packages, #Shiny apps, automated data workflows, and training them on #ReproducibleResearch practices. I also mentor data scientists for @Posit Academy. I am #OpenToWork as a contractor if any of those skills sound useful to you.

My background is in plant chemical ecology and population ecology and for my PhD I studied #tea and did field work in China. I love tea (although I've been drinking coffee more and more lately) and practice #GongFuCha when I can. I love #foraging and tasting new things.

I currently live in #Tucson but the #BayArea will always be my home.

**EU industrial production: 0.6% annual growth since 2000**

"_At country level, the highest average growth rates between 2000 and 2024 were observed in Ireland (5.6%) and Poland (4.9%), while the lowest rates were registered in Italy (-1.1%) and Portugal (-0.9%)._"

June 2025 data is now available for both Antarctic sea-ice thickness/volume (https://zacklabe.com/antarctic-sea-ice-extentconcentration/) and global sea-ice volume (https://zacklabe.com/global-sea-ice-extent-conc/) from GIOMAS.

Last month's global sea-ice volume has fallen to near-record low levels for the month of June in this dataset.

**Global inequality is the result of two centuries of uneven economic growth**

"_Two hundred years ago, people in all regions were similarly poor. Today, the average incomes of people in Australia, the US, or Denmark are more than 15 times higher than those in Sub-Saharan Africa._"

**Americans are increasingly likely to say AI will negatively affect society**

"_The share of Americans who believe that the effects of artificial intelligence on society will be negative has steadily increased, from 34% in December 2024 to 40% in March 2025 to 41% in April and to 47% in June._"

In today's #gleo news: wind data!

Or, more technically: a 2-band raster covering the globe and properly warped (EPSG:4326→EPSG:3857) containing UV speed data, visualised as a particle trail simulation.

Thanks to the #FOSS4GE2025 for providing the environment that has let me pull this off.

Do you like Grafana dashboards? Me too!
Do you enjoy creating them? Me neither!

Here's my latest experiment in using AI to handle the tedious work: digging through data and creating panels.

For this, we used Open Air Quality data loaded into a ClickHouse SQL database.

#Arctic climate rankings are in for June 2025: https://zacklabe.com/archive-2025/. While sea ice remained low, it was an unusually cool month temperature-wise. This was especially notable north of 75°N latitude.
