Natural disasters associated with climate change put people at risk of injury and death, and alter the prevalence and distribution of illnesses and infectious diseases.
If the world overshoots its climate targets, drought could cause dryland areas to expand by a quarter and encompass half the Earth’s land area, threatening lives and livelihoods.
Academic research can have a direct impact on people's lives. It's crucial to come together to deal with problems like climate change. If we don't, the poor and vulnerable will suffer the most.
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.
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.
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.
Desalination can help meet growing water needs globally. But toxic wastewater and inefficiency hamper current techniques. A new approach uses custom membranes to clean water more easily.

The world’s first futures market for water launched in California in December. Two commodities experts explain how it works, what the potential problems are and why there’s no reason to freak out.
This is not an imaginary future dystopia. It’s a scientific projection of Australia under 3°C of global warming – a future we must both strenuously try to avoid, but also prepare for.
