This animated map by @AaronJBecker shows the average colour of Europe from September 2024 to September 2026 based on satellite images. It's fun to look at your region changing colour through the seasons.

This animated map by @milos_gis shows how firey and smokey the last three months in Europe were. We see wildfires and aerosol spread over the last 3 months.

I believe that a lot of the anger in the US population is rooted in these two charts. How and where this anger is channelled to determines the future of the nation. Different groups offer different solutions, different paths. What solution will win out in the long-run is still undecided.

You read a lot about The South China Sea as a current geopolitical hotspot. Have a look at this 1944 map from the US Navy to see that this isn't a new development at all. Really interesting map. Source: buff.ly/3EuXeLO #mapmonday

This map is a clever new way of displaying data about the Ottoman Empire. It shows how man years areas in the Western Balkans spent under Ottoman control. I really like this map! Source: buff.ly/2XJTBvu

Every glaciated region on the planet lost ice for four years in a row now. From 2023–2025 alone, glaciers lost around 1,400 gigatonnes of ice, equivalent to roughly 560 million Olympic swimming pools (the official weird measure for anything water related). Source: bit.ly/WMOStateofWa...

When plotting the divorce rate against years of marriage a relatively stable curve emerges. Watch out if you've been married for exactly five years!

Huge drop in web traffic to the biggest US news websites. I know that the anti-mainstream media is loving this but news are now consumed from unruly sources to a higher degree than before. That opens up the flood gates for misinformation more than before.

The West used to create new urban land by reclaiming coastlines. Then it largely stopped in the 1970s. The authors argue the constraint isn’t technology or geography, but environmental regulation and permitting. Meanwhile China, Singapore and Japan kept building land. Source: buff.ly/jqSztrk
