NASA uses the vantage point of space to increase our understanding of Earth and improve lives.
Millions of people in #California live in low-lying coastal areas where land subsidence is exacerbating the risks of sea level rise.
Happy Halloween! The Moon is haunting when glints of moonlight reflect off Earth’s water. In 2015, moonglint on the Mediterranean Sea provided quite an eerie sight for @NASA_Astronauts . #NASAHalloween
There's a severe drought in South America. Satellite gravimetry data indicates it is the continent's second most intense drought since 2002.
Around the world, sea level is rising. Right now, the global average sea level rises about an eighth of an inch every year. And it’s accelerating, with seas rising a little faster every year. #SeeingTheSeas
Sea levels on the West Coast of the United States are rising at a faster rate than the global average – and that trend is likely to continue for at least a few years, with likely effects for people living in the region. #SeeingTheSeas
Sentinel-6 Michael Freilich will use altimetry to precisely measure the height of the sea — bouncing radar pulses off the ocean’s surface and timing how long they take to return to the spacecraft.
NASA's AIRS instrument maps carbon monoxide (CO) from fires burning in Brazil's Amazon region. This time series ⬇️ shows CO high in the atmosphere over Brazil from Aug. 8-22, 2019. Each "day" in the series is made by averaging three day's-worth of data:
Though located a world away, Lake Salda, #Turkey , has geological similarities to Jezero Crater on #Mars . In fact, researchers even did field work at Lake Salda to prepare for #CountdownToMars and @NasaPersevere .
This decades-long warming trend is the result of increasing greenhouse gases ♨️ in the atmosphere, released by human activities.
2019 was the second hottest ? year and the last decade was the warmest decade on record. The global average temperature was more than 2°F warmer than during the late 19th century.
Germany may be heading toward its third summer of drought in a row due to high temperatures and sparse precipitation.
