A new study, published in Nature Climate Change, offers a comprehensive picture of public attitudes toward climate policies, such as carbon taxes, in seven large countries in the Global South: Chile, Colombia, India, Kenya, Nigeria, South Africa, and Vietnam. The study highlights both the depth of climate knowledge in these countries and the trade-offs citizens face when weighing climate policies against other urgent needs.

A new global study shows that hotter and drier conditions are making food production more volatile, with crop yields of corn, soybean and sorghum swinging more sharply from year to year. For some, it may mean pricier burgers; for others, it can bring financial strain and hunger.

A new IIASA-led study for the first time maps safe areas that can practically be used for underground carbon storage, and estimates that using them all would only cut warming by 0.7°C. The result is almost ten times lower than previous estimates of around 6°C, which considered the total global potential for geological storage, including in risky zones, where storing carbon could trigger earthquakes and contaminate drinking water supplies. The researchers say the study shows geological storage is a scarce, finite resource and warn countries must use it in a highly targeted way.
