In 2025 that ended: Central Asia lost a record ~30 km³ of ice — nearly 2% of what remains — in a single year, and new research shows the anomaly tipped around 2018 when snowfall collapsed. Mapped, with what it means for the Amu Darya and the millions who depend on its meltwater.

Father’s Day is the most globally synchronized holiday on the calendar: roughly 86 countries — the US, UK, Canada, India, Japan, Mexico and most of Africa and Asia — celebrate on the third Sunday of June (June 21 in 2026). But Catholic Europe honours fathers on March 19 (St Joseph’s Day), the southern hemisphere waits until spring, Germany ties the day to Ascension, and a long tail from Thailand to Taiwan to Russia picks its own date. This post maps every country’s Father’s Day and explains why one parent’s holiday is so neatly aligned while the other’s is scattered across the year.

Mapped: every country’s prosperity, and where it diverges from freedom.
