The world is experiencing more frequent and intense heat waves, floods, hurricanes, and wildfires due to rising greenhouse gas emissions. The energy sector is one of the largest contributors to climate change, yet it also plays a crucial role in the strategies needed to mitigate and adapt to its effects, contributing to the achievement of ambitious climate goals.

A pre-Columbian society in the Amazon developed a sophisticated agricultural engineering system that allowed them to produce maize throughout the year, according to a recent discovery by a team of researchers from the Institute of Environmental Science and Technology (ICTA-UAB) and the Department of Prehistory at the Universitat Autònoma de Barcelona, (Spain); the Universities of Exeter, Nottingham, Oxford, Reading and Southampton (UK); the University of São Paulo (Brazil) and Bolivian collaborators. This finding contradicts previous theories that dismissed the possibility of intensive monoculture agriculture in the region.

Grasslands in Asia and North America differ in their responses to drought, according to a new paper in the journal Nature led by faculty at Colorado State University. The findings show that differences in the dominant grasses and lower species diversity in the Eurasian Steppe grasslands may make it more vulnerable to drought than the North American Great Plains.
