"Extraordinarily" refers to values above the 95th percentile or below the 5th percentile of the reference period (1961-1990). In other words, 70% of all days in 2024 had temperatures that would usually only be observed 5% of the time.

🌡️ The recent #HeatWave in #Mexico has been intense, with cities like #Oaxaca experiencing prolonged periods of extreme temperatures. Here's a visualization I created about the number of hot and cold days. In 2024 104 out of 148 days (70%) were extraordinarily hot. #dataviz 📊 #ClimateChange

For day 21 of the #30DayChartChallenge (green energy), I updated a visualization I made about a year ago. It shows daily electricity production shares from renewable sources.

The good news: The yearly average has risen to almost 56% in 2023, with daily peaks of above 80%.

My contribution for day 1 of the #30daychartchallenge (part-to-whole): Global military expenditure as documented by the SIPRI Milex Database (milex.sipri.org/sipri). It will be very interesting to see how those numbers evolved in 2023, but that data is still not available.

Happy to see my map on the Guyana/Venezuela conflict over Esequibo published on amerika21.de today.

Some more context information to the #datavisualization of data from IOM's Missing Migrants Project: Yearly data for the region that is hovered.

58,444 dead or missing human beings have been documented by the Missing Migrants Project of the IOM since 2014 (latest incident: Sep 5th 2023). The actual number is likely much higher.

Here's a #Datavisualization I made of that horrendous number.
