Carbon Dioxide Information Analysis Center
The Carbon Dioxide Information Analysis Center (Thomas A. Boden, Director), which includes the World Data Center for Atmospheric Trace Gases, has served as the primary climate-change data and information analysis center of the U.S. Department of Energy (DOE) since 1982.

Año de la Biodiversidad
The UN has declared 2010 the International Year of Biodiversity. It’s an opportunity to reflect on our achievements to safeguard biodiversity and focus on the urgency of our challenge for the future.
Biological diversity – or biodiversity – is the term given to the variety of life on Earth and the natural patterns it forms. The biodiversity we see today is the fruit of billions of years of evolution, shaped by natural processes and, increasingly, by the influence of humans. It forms the web of life of which we are an integral part and upon which we so fully depend.
This diversity is often understood in terms of the wide variety of plants, animals and microorganisms. So far, about 1.75 million species have been identified, mostly small creatures such as insects. Scientists reckon that there are actually about 13 million species, though estimates range from three to 100 million.
Biodiversity also includes genetic differences within each species – for example, between varieties of crops and breeds of livestock. Chromosomes, genes, and DNA-the building blocks of life-determine the uniqueness of each individual and each species.

First Census of Marine Life 2010: Highlights of a Decade of Discovery
The Census of Marine Life is a global network of researchers in more than 80 nations engaged in a 10-year scientific initiative to assess and explain the diversity, distribution, and abundance of life in the oceans. The world’s first comprehensive census of the past, present, and future of life in the oceans is being released in 2010.
The Mapping and Visualization Team based at Duke University’s Marine Geospatial Ecology Lab is responsible for developing and sharing methods to display the results of the ten-year Census of Marine Life. Most Census projects are developing their own maps and visualizations.
The following images highlight a variety of maps and visualizations resources produced by the Census projects. Additional information can be found on each individual Census project website.

The security of water supply for humans and the biodiversity of rivers are often seen as competing goals, but need that be the case? A new global-scale analysis of freshwater resources advances the field by considering threats to both river biodiversity (on the left on the cover) and to human water security, after accounting for investments in infrastructure and water services (right). The maps reveal that the world’s rivers are in a state of crisis. Achieving a sustainable solution to these problems, the authors say, will require strategies that jointly address water security for humans and biodiversity. COVER CREDIT: Stanley Glidden
