Even though annual precipitation is rising nationally, the landscape is drying out more rapidly. That’s changing the water cycle.

A new study shows how thawing permafrost and intensifying storms will change how water moves into and through Arctic rivers.
‘Green water’ is essential for healthy soils and a benign climate, but it’s under threat.
Groundwater is the second-largest store of water on Earth. Governments and industry use groundwater reservoirs to store waste, but it may also have environmental functions that haven’t been revealed.
The water cycle is intensifying as the world warms, bringing heavier downpours and longer droughts.
We modelled surface water across Africa to show which parts of the continent are climatically-suitable for malaria – and how this will change.
Over the past 20 years, Great Lakes water levels have gone from sustained multiyear lows to multiyear highs. Climate change is accelerating the transition between dry phases and wet phases.
While making small volumes of pure water in a lab is possible, it’s not practical. The reaction is expensive, releases lots of energy, and can cause really massive explosions.
When water turns from a gas into a liquid, it forms droplets. Whether those droplets are dew or rain depends on where the droplet forms.
Footprints get people thinking about their own impact, but for water the analogy simply doesn’t work.
Clouds formed by rising warm air currents are called ‘convection clouds’. Because of all the rising air coming up, these clouds can be bumpy on top, sometimes looking like cotton wool or cauliflower.
It was the Seine’s rise and fall, in response to heavy rain, that inspired our current understanding of river systems.
