Dust cloud above a dried out field
New modelling by a multidisciplinary team of researchers shows the impact climate change and extreme weather events could have on food supply chains, with adverse effects on income, food and nutrient availability.
Wildfire in Australia
New data on forest fires confirms what we’ve long feared: Forest fires are becoming more widespread, burning nearly twice as much tree cover today as they did 20 years ago.
A new study focuses on the frequency and distribution of tropical cyclones over the past 40 years.

While funding is pumped into preventing low-probability scenarios such as asteroid collision, the far more likely threat of a large volcanic eruption is close to ignored – despite much that could be done to reduce the risks, say researchers.
New research by an international team of scientists suggests that climate change is causing dryland mechanisms to increasingly affect Earth’s wetter areas.
People line up for water rations in Kathmandu, Nepal
Most comprehensive study to date on water storage in Tibetan Plateau projects dramatic losses of freshwater storage in parts of Asia by mid-century under modest climate policy scenario.

A recent global study conducted by the Joint Research Centre looks at the difference between surface temperatures of urban areas and their neighbouring rural areas in summer.

The water volume in small reservoirs is significantly more susceptible to seasonal and climate variability than larger reservoirs, leaving communities that rely on them more vulnerable to water scarcity and food insecurity, according to new research.

When temperatures exceed 36°C and relative humidity passes 58%, citizens in China may experience heat stroke.
A farmer takes a break in the midday heat
An analysis finds that the apparent temperature, or heat index, calculated to indicate how hot it feels—taking into account the humidity—underestimates the perceived temperature for the most sweltering days, sometimes by more than 20 degrees Fahrenheit.
