Water World

Oceans, rivers, polar ice, water systems, marine life, and the environmental changes affecting the planet's blue and frozen regions.

Iron and Ice

Jupiter is so massive that its shared centre of gravity with the Sun lies just outside the Sun’s surface — making it the only planet whose individual barycentre with the Sun falls beyond the Sun itself, and the largest contributor to the star’s planetary wobble.

The Sun-Jupiter balance point lies about 742,000 kilometres from the Sun's centre at Jupiter's mean distance, but the full Solar System makes the Sun's real path more complex.

On Washington’s Olympic Peninsula, after two dams came down on the Elwha River, average Chinook returns rose from 2,827 fish a year to 4,734 — and the share taken for hatchery breeding fell from 53 per cent to 31 per cent as more Chinook were left to spawn in the restored channel

Iron and Ice

Saturn's moon Titan is the only place beyond Earth where a person could stand outside without a pressure suit — its atmosphere is 50 per cent thicker than ours and blocks even the galactic cosmic rays that would make Mars lethal over time

After crews finished the largest dam-removal project in American history on the Klamath River, 7,700 fish passed the rubble of Iron Gate in three months — 96 per cent of them Chinook salmon, swimming into 650 kilometres of habitat no salmon had reached in more than a century.

We tend to think of AI as a software problem, weightless and waterless, but even a 100-word email written with ChatGPT has been estimated to require roughly a bottle’s worth of water once data-centre cooling and electricity generation are counted — and scaled to global demand, researchers project AI could withdraw 4.2 to 6.6 billion cubic metres of water a year by 2027, roughly half the United Kingdom’s annual freshwater withdrawals.

Iron and Ice

Titan is the only moon among the 150-plus in the solar system with a thick atmosphere — its air presses on the surface about 1.5 times harder than Earth's at sea level, roughly what you'd feel at the bottom of a swimming pool
