Learning about sustainable development and consumption should not be limited to particular disciplines like those in the sciences and technologies.
Wetlands created by beavers, like this one in Amherst, Massachusetts, store floodwaters and provide habitat for animals and birds.

Beavers in our landscapes have great potential to provide small-scale adaptations to climate change – if humans can figure out how to live with them.

A draft plan for Sydney’s water supplies includes expanding desalination and potentially adding highly treated sewage to drinking water. All options must be on the table as the climate warms.
Wildfires that swept through Sequoia National Forest in California in September 2021 were so severe they killed ancient trees that had adapted to survive fires.

US disasters in 2021 told a tale of two climate extremes. A climate scientist explains why wet areas are getting wetter and dry areas drier.
California has been through two straight year of drought, and water supplies are limited.

Long before climate change was evident, California began planning a system of canals and reservoirs to carry water from the mountains to drier farms and cities. It’s no longer enough.
Several of California’s reservoirs were at less than one-third of their capacity in early December 2021.

The State Water Project cut its initial allocations for water agencies to 0% for 2022. A California water expert explains why.

A Western scholar proposes allocating water from the Colorado River based on percentages of its actual flow instead of fixed amounts that exceed what’s there – and including tribes this time.

This hardy desert plant lives in the hostile Atacama Desert in Chile by sucking moisture out of passing fog. As water resources become ever more scarce, humans could follow suit.
Higher temperatures cause drought, and can lead to food insecurity.

Many of the temperatures presently being recorded in Africa, and those projected in the next decade, are already close to the limits of human survival, or “liveability”.

Each year the global temperature is 1 C above the 1951-80 average temperature, glaciers lose, on average, about 0.8 metres of water equivalent depth.

Policy-makers need the courage to commit to meaningful reductions of greenhouse gas emissions if we want to avoid the widespread loss of mountain glaciers.
Tree rings can tell us about periods of drought, warmth and heavy rainfall in the past.

A consequence of a warming world is prolonged dry spells and periods of drought that can lead to infectious diseases like cholera.
