From cooling power plants to quenching thirst and growing crops, water is part of everything we do.

February 22, 2019 — As climate change, urban development, irrigation and other factors are altering the availability of water, it’s important to understand how we use water on a daily basis in the U.S. — and where the opportunities are for using it more wisely.

A recent report from the … [more…]

There are about 13,000 miles of coastline in the 48 contiguous United States, and by the end of the century, these contours will be greatly altered by climate change.

By the close of the 21st century, about 2.5 million properties worth $1.07 trillion, in cities … [more…]

Drilling deeper not a long-term strategy, authors say.

When a severe drought enveloped California a few years ago and rivers shriveled, farmers in the Central Valley punched wells deeper underground, seeking to tap water reserves that were untouched by aridity on the surface.

In … [more…]

Climate change: How 1.5 degrees could change the world

It’s the final call, say scientists, the most extensive warning yet on the risks of rising global temperatures.

Their dramatic report on keeping that rise under 1.5 degrees C says the world is now completely off track, heading instead towards 3C.

Keeping to the preferred target of 1.5C above pre-industrial levels will mean "rapid, far-reaching and unprecedented changes in all aspects

Change in Water Storage Maps Added to Living Atlas

heat map: Change in Water Storage Maps added to the Living Atlas

A new image service has been added to the Living Atlas of the World. It shows monthly change in water storage, as derived from NASA’s GLDAS dataset.

Change in storage is calculated by subtracting the water output (runoff and evaporation) from water input (rainfall). Where the input is higher than the output, this means water is being stored in the landscape. Where output is higher than the input, storage is … [more…]
