Arctic Emergency: Scientists Speak On Melting Ice and Global Impacts. This film by Max Wilbert brings you the voices of climate scientists - in their own words.

Rising temperatures in the Arctic are contributing the melting sea ice, thawing permafrost, and destabilization of a system that has been called "Earth's Air Conditioner".

Global warming is here and is impacting weather patterns, natural systems, and human life around the world - and the Arctic is central to these impacts. Published on Aug 1, 2014

An ultra-high-resolution NASA computer model has given scientists a stunning new look at how carbon dioxide in the atmosphere travels around the globe. Very interesting.

Plumes of carbon dioxide in the simulation swirl and shift as winds disperse the greenhouse gas away from its sources. The simulation also illustrates differences in carbon dioxide levels in the northern and southern hemispheres and distinct swings in global carbon dioxide concentrations as the growth cycle of plants and trees changes with the seasons.

The carbon dioxide visualization was produced by a computer model called GEOS-5, created by scientists at NASA Goddard Space Flight Center’s Global Modeling and Assimilation Office.

The visualization is a product of a simulation called a “Nature Run.” The Nature Run ingests real data on atmospheric conditions and the emission of greenhouse gases and both natural and man-made particulates. The model is then left to run on its own and simulate the natural behavior of the Earth’s atmosphere. This Nature Run simulates January 2006 through December 2006.

While Goddard scientists worked with a “beta” version of the Nature Run internally for several years, they released this updated, improved version to the scientific community for the first time in the fall of 2014.

"Vital Signs: Taking the Pulse of Our Planet" was the theme for NASA's Goddard Space Flight Center's fifteenth installment of its annual lecture and reception sponsored by the Maryland Space Business Roundtable. Published on Oct 23, 2014

Earth is a complex, dynamic system we do not yet fully understand. Like the human body, the Earth system comprises diverse components that interact in complex ways.

On this global tour, scientists lead the viewer through Earth's water cycle, forests and frozen regions as seen through the eyes of NASA's Earth observing satellite fleet. They share a story of how we can make life better today and into the future.

NASA's Earth science program aims to develop a greater understanding of Earth's system and its response to natural or human-induced changes, and to improve predictions of climate, weather and natural disasters.
