| Posted: 07 Sep 2009 11:41 AM PDT Earth Observatory has an interesting satellite image pair of an area within the Station Fire, which burned near Los Angeles. A true-color image shows a smoke covered landscape but the false-color image combines shortwave-infrared light, near-infrared light, and green light to reveal burn scars, burn fronts and hotspots. |
| Human Actions to Cool Planet Earth? Posted: 07 Sep 2009 09:52 AM PDT National Geographic has a blog post that speculates on how humans might be required to try risky geoengineering to cool the planet if efforts to curb greenhouse gas emissions are not successful. |
| Posted: 07 Sep 2009 09:42 AM PDT Earth Observatory has photograph of the Black Point Lava Flow in northern Arizona taken from the International Space Station. The flow is part of Arizona’s San Francisco Volcanic Field, a group of geologically young (approximately six million to less than one thousand years old) volcanoes, lava flows, and cinder cones located just north of Flagstaff, [...] |
