Climate change has a wide range of effects on wildlife. It affects seasonal migration, reproduction times, body size and mass, and disrupts ecological processes, thereby posing challenges for the populations of some species. An international team of scientists has now analysed more than 200 scientific studies on 73 animal species in a meta-study to determine exactly how climate change is related to phenology, morphology and population trends. The team explains in the journal Nature Communications that phenological traits – seasonal developmental phenomena – are very sensitive to temperature changes and that this represents a mechanism for many species to cope with climate change.

Providing accurate information about the climate crisis can help to correct misperceptions about how much public support exists for action.

Climate change is affecting the nutrition of everyday foods, which could increase health risks, especially in vulnerable communities.

Dietary supplements may help fill emerging nutrition gaps, but questions remain about their safety, effectiveness, affordability and appropriate use.

A new study by IIASA researchers offers a pioneering way to understand how climate change affects people’s lives over the long term. Using a global model and the Years of Good Life (YoGL) metric, the research shows that today’s emissions shape future wellbeing, especially for younger generations.
