Millions of people in #California  live in low-lying coastal areas where land subsidence is exacerbating the risks of sea level rise.

As #HurricaneZeta  makes landfall in the U.S., @NASA  researchers are preparing to provide information to communities in its path, working closely with @fema  and local agencies.

Cameras aboard the @Space_Station  captured footage of #Zeta  earlier today.

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.

One of the tallest tsunami waves known to science slammed Lituya Bay in 1958. Evidence of the damage the cataclysmic wave did to the surrounding forest is still visible with Landsat. #Alaska 


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:

Airborne Nitrogen Dioxide Plummets Over China #NASA 

How it started: How it’s going:

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.
