Ein Artikel in der führenden Fachzeitschrift The Lancet schätzt, dass bis zu 186.000 oder mehr Todesfälle durch den aktuellen Konflikt im Gazastreifen verursacht sein könnten. Dies wären 7,9 % der Gesamtbevölkerung.

🌡️ 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
Chart titled 'Number of hot days in Mexico hits records in 2024' showing the frequency of extraordinarily hot and cold days in Oaxaca, Mexico, from 1940 to 2024. The chart highlights that 70% of the days in the first five months of 2024 were extraordinarily hot, with no extraordinarily cold days and only 2% of days below average temperature. Bars in red represent extraordinarily hot days, and bars in blue represent extraordinarily cold days. The chart shows a significant increase in hot days starting in the late 20th century, peaking in 2024. Values are compared to the reference period of 1961-1990.

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%. 📊 #dataviz
A heatmap displaying daily shares of electricity production from renewable sources in Germany 2015-2023. It shows that these shares have grown significantly over the years.Three line graphs showing how electricity production in Germany has developed for conventional, fossil, and renewable sources from 2016 to 2023. The first two show a clear decline, the last one grew by more than 50%.An area graph showing the development of electricity production in Germany 2016 to 2023 by production source.

Today's #30DayChartChallenge theme is "correlation". This is one of my all time favorite correlations.

Today's #30DayChartChallenge theme is "diverging". I chose to temperature anomaly data. A "temperature anomaly" in this case is the difference between the observed global temperature and the 1901-2000 global average. Always a sobering dataset to use.

Not sure how much of #30DayChartChallenge I'll be able to join. For day 1, I'm trying out RAWGraphics tool on UN satellite analysis data: 35% of structures destroyed or damaged in the Gaza strip by March 2024. #dataviz #ceasefireNOW
Voronoi Treemap chart done with RAWGraphics showing among damaged buildings in the Gaza strip by March 2024, some are destroyed, severely or moderately damaged.Overview of the UN satellite data analysis report published on 20 March 2024. For more see unosat.org/products/3804.

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.
NATO Dominates Military Expenditure
In 2022, NATO's 30 members made up over 54% of world military spending, with the USA outspending the next eight countries combined. Following were China, India, and Saudi Arabia. Russia, who started its war on Ukraine in 2022, ranked fifth at that point.

February 2024 was the warmest February on record in the ERA5 dataset, at around 1.79C above preindustrial records. It beat the prior record set during the 2016 super-El Nino by 0.12C: pulse.climate.copernicus.eu

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. Interactive version: yotka.org/missing-migr...
Beeswarm plot that shows dates, regions, and number of missing people for more than 13,000 incidents in which migrants died or went missing.
