At any given moment, about 20 volcanoes on Earth are actively erupting. Often among them is Mayon--the most active volcano in the Philippines. The nearly symmetrical stratovolcano, on Luzon Island near the Albay and Lagonoy gulfs, rises more than 2,400 meters (8,000 feet) above sea level.

As the former CEOs of two of the largest water utilities using water from the Colorado River, we have been deeply engaged in interstate and federal negotiations on the river for over 30 years. Those negotiations were tough, but the basin states ultimately reached agreement, including reducing California's use of water by 800,000 acre-feet and adopting the current set of operating rules for the federal reservoirs.

On March 3, 2026, Earth lined up directly between the Moon and the Sun, casting its shadow on the full Moon. The total lunar eclipse was visible throughout the Americas, East Asia, Australia, and the Pacific. Skygazers in those parts of the world may have witnessed a "Blood Moon," when the dimmed lunar surface temporarily turned an orange-red color.

Iceberg A-23A has had a more eventful run than most of the large Antarctic icebergs that have calved from the continent's ice shelves in recent decades. Over its winding, forty-plus-year journey, the "megaberg" spent decades grounded in the Weddell Sea before drifting north, twirling in an ocean vortex for months, and nearly colliding with an island in 2025.
