Climate change is the defining challenge of the 21st century
Human activities and resource use are altering Earth’s climate, through emissions of greenhouse gases and particulates, and through alteration of the land surface. Climate change, in turn, is affecting other Earth processes. Stanford Earth faculty work across disciplines—and at the interface of atmosphere, ocean, land, ice systems, and human behavior. They characterize climate changes and help develop adaptation strategies that matter to people.
As the most-used building material on the planet and one of the world’s largest industrial contributors to global warming, concrete has long been a target for reinvention. Stanford scientists say replacing one of concrete’s main ingredients with volcanic rock could slash carbon emissions from manufacture of the material by nearly two-thirds.
