In celebration of this year’s Earth Day on April 22, NASA’s Webby Award-winning Global Climate Change website, http://climate.nasa.gov , has unveiled a new version of its popular image gallery, “State of Flux.” The gallery, which can be found at http://climate.nasa.gov/sof , presents stunning images, mostly from space, of our ever-changing planet, chronicling changes taking place over time periods ranging from days to centuries.

Each image pair in the continuously updated gallery highlights before-and-after impacts of change, including the destruction wrought by extreme events such as wildfires and floods, the retreat of glaciers caused by climate change, and the expanding footprint of urban areas due to population growth.
