The changing colors of our living planet
From space, satellites can see Earth breathe. A new NASA visualization shows 20 years of continuous observations of plant life on land and at the ocean’s surface, from September 1997 to September 2017. On land, vegetation appears on a scale from brown (low vegetation) to dark green (lots of vegetation); at the ocean surface, phytoplankton are indicated on a scale from purple (low) to yellow (high
Spikes in carbon emissions detected with NASA satellite
Spikes in carbon emissions detected with NASA satellite. Data from a circling NASA satellite shows spikes in carbon emissions worldwide, particularly in winter, along with new insights into the rising levels of pollutants that drive global warming, researchers said Thursday.
Bay of Bengal: depleted fish stocks and huge dead zone signal tipping point | Fishing
After nightfall, a glow that is bright enough to be visible from outer space hangs above the archipelago, like a miasmic fog. These squid boats, some of which are probably crewed by men who have been trafficked like slaves, help to make Thailand the world’s largest exporter of squid – at least for the time being.
Psychedelic Swirls Show Algae Bloom from Space
Dreamy swirls and loops seen on satellite represent a cyanobacteria bloom in the Baltic Sea. Cyanobacteria were the first organisms to develop photosynthesis, a talent they acquired some 2.4 billion years ago, scientists have said. The waste product of this process — oxygen — altered Earth's atmosphere drastically, paving the way for complex life. Cyanobacteria also made plants possible.
Lake Mead's Water Sinks to Lowest Level Since 1930s
Lake Mead's Water Sinks to Lowest Level Since 1930s. Arizona, Nevada, California and northern Mexico all depend on Lake Mead's water, with the Las Vegas Valley relying on the reservoir for about 90 percent of its water supply, NASA officials said. In 2008, a study concluded that Lake Mead could dry up by 2021.
