The pandemic-related drop in greenhouse gas emissions in 2020 was likely the largest on record in a single year, but how our recovery might affect future emissions is less clear. New modeling examines alternative scenarios and how they could impact climate mitigation targets.

New research on China suggests that declining birth rates and an aging population might not hinder future prosperity when associated with better education of the young.

Children are to face disproportionate increases in lifetime extreme event exposure – especially in low-income countries, according to new research by an international group of scientists.

Storing greater amounts of water in Brazil’s reservoirs could increase precipitation and river flow, alleviating the water and energy supply crisis in Brazil.

Environmental targets to limit excess nitrogen require the large-scale deployment of dedicated nitrogen mitigation strategies to avoid a strong increase in the risk of food insecurity. Without these measures, the amount of dietary energy available to people would be greatly reduced, which would in turn lead to high food prices and an increase in the number of undernourished people.

The social cost of carbon dioxide is one of the most influential indicators of climate change as it allows us to estimate the cost of greenhouse gas emissions to humanity. A new study looks back on how ten years of scientific advancements have influenced such estimates, and explores how to resolve some of the most important outstanding gaps in existing models.

For many, an increase in living standards would require an increase in energy provision. At the same time, meeting current climate goals under the Paris Agreement would benefit from lower energy use. IIASA researchers have assessed how much energy is needed to provide the global poor with a decent life and have found that this can be reconciled with efforts to meet climate targets.

Using a novel modeling approach, new research published in Nature Ecology and Evolution reveals the location and intensity of key threats to biodiversity on land and identifies priority areas across the world to help inform conservation decision making at national and local levels.

IIASA researchers have contributed to a study that provides a new model to monitor and predict food insecurity in the coming decade. It finds that while overall global levels of food insecurity are set to decrease an increase is implied for lower income countries.
