China's tree belt around the Taklamakan Desert has become a carbon sink

Decades of planting trees along the Taklamakan Desert in northwest China (the world's largest shifting-sand desert) have increased vegetation enough to create a measurable carbon sink, absorbing more carbon dioxide than the area emits. The effort demonstrates a key large-scale climate mitigation strategy, though it has raised concerns over water use and long-term sustainability.

Machu Picchu, 101

Machu Picchu was built right on top of two intersecting fault lines, which makes it even more baffling how its temples and terraces have survived for more than 500 years—especially since no mortar was used to hold the precisely cut stones together. As this three-minute NatGeo video explains, this ingenious construction method allows the stones to bounce in place when earthquakes hit, shaking and rattling but rarely collapsing.
