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.
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”.
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.
The picture seems hopeless, but with mitigation and adaptation strategies and policies driven through COP26, southern Africa can reduce the impacts of climate change on local livelihoods.
Studies show climate change is raising the risk of cascading hazards that alone might not be extreme but add up to human disasters. Communities and government agencies aren’t prepared.
More than half of the world’s population lives in cities, and that share is growing. Rapid climate change could make many cities unlivable in the coming decades without major investments to adapt.
As surface water diminishes in the Western US, people are drilling deeper wells – and tapping into older groundwater that can take thousands of years to replenish naturally.
Monsoons are weather patterns that bring thunderstorms and heavy rains to hot, dry areas when warm, moist ocean air moves inland. They’re challenging to forecast, especially in a changing climate.
Cities and farmers in the Southwest are resorting to unsustainable strategies to pull in more water. Iran has tried many of these strategies and shows how they can go wrong.

How scientists are improving their understanding of the connection between extremes and climate change – and what’s to come. Listen to The Conversation Weekly.
Many plants are really good at withstanding bushfires, but the combination of drought, heatwaves and pest insects under climate change may push them to the brink.
