The tropics are already hot, and they’re getting hotter as global temperatures rise. A new study offers a glimpse into how seriously a couple more degrees could disrupt the region’s ecological map.
The SEDAC Hazards Mapper is designed for disaster risk managers, humanitarian response organizations, public health professionals, journalists and others needing a quick assessment of the potential dangers posed by a major hazardous event or developing emergency.
Even the simplest research questions can lead to far-reaching public benefits. Consider Chris Small and Joel Cohen’s study of global population by altitude, being honored this week at the Library of Congress.
Some of the world’s poorest nations have an abundance of natural resources, but also have suffered under recent conflicts. Learning how to manage these resources strategically and sustainably can help accelerate growth and development. A new web-based mapping tool may be able to help them do that.
Columbia University is teaming up with Cornell University to co-host the second International Global Food Security Conference to bring together 500-plus scientists to investigate the behavioral, biophysical, economic, institutional, political, social and technological drivers of current and future global food security.
In 2011, the U.N. announced that the world population had reached 7 billion. This year’s new projections for future population growth are higher than previously expected. Projects like Millennium Cities hope to alleviate many of the pressures that crowded cities place on infrastructure, public services, and the environment.
Mothers, carbon, trash, vanishing ice and “secret lives”: Watch a movie for Earth Day and learn.
This map shows the estimated number of people in 2010 living at different elevation levels across several Southern Asian countries. The database it’s taken from lets users without specialized geospatial training or software compare populations in various environmental contexts in different countries.
Population growth is a key contributor to the pressures pushing at our planetary boundaries. In Rio+20 discussions, implications of population growth have become shrouded in platitudes. It is important that discussions on planetary limits clearly lay out possible strategies that can alleviate these pressures.
