Earthrise.

On Christmas Eve of 1968, the Apollo 8 crew photographed Earth rising over the lunar surface as they orbited the Moon.

“We came all this way to explore the Moon, and the most important thing is that we discovered the Earth." – William Anders https://go.nasa.gov/3GcD3F4

Early warnings on floods can save lives, but roughly half of the world's countries lack adequate early warning systems.

That's about to change, thanks to a new tool developed by @nasa and the Pacific Disaster Center (PDC).

This is the first time comprehensive global flood early warnings at the sub-watershed level have been possible.

Thanks to MoM and DisasterAWARE, small and vulnerable communities now have a powerful new tool to take early action on flooding and protect lives and livelihoods.

Scientists mapped the thickness of the lava flows from Mauna Loa with @nasa aircraft. 🌋🛩

The airborne data is overlaid on a #Landsat 8 image with topography from a digital elevation model.

Thicker lava flows are shown in yellow and thinner in teal.
#NASAEarth


These airborne measurements helped @usgs scientists calculate that 230 million cubic meters of molten rock poured from the volcano during the two-week eruption.

In 2020 and 2021, global atmospheric concentrations of methane – a potent greenhouse gas – surged in record growth since measurements began ~40 years ago.

This video shows global methane emissions from wetlands since 1980. Wetlands are one of the largest single methane sources.
#NASAEarth


Wetlands store massive quantities of carbon in soils. But as the climate gets warmer or wetter, microbes in the wetlands start releasing more methane into the atmosphere.

On Dec. 14 at 2pm ET, @nasa scientists are discussing their findings at #AGU22. https://go.nasa.gov/3UYuIcp
#NASAEarth


This fall, @nasagoddard scientists trekked through and flew over Florida marshes as part of the Blueflux project.

The team is studying the exchange of carbon and methane through mangrove ecosystems with research aircraft and scientists on the ground. 🛫 🛶https://go.nasa.gov/3Wjds2I
#NASAEarth


For the first time, @nasa scientists mapped global salt marsh losses and their carbon impact.

The world has lost 561 square miles (1,453 square kilometers) of marshes over the past 20 years, the team found. https://go.nasa.gov/3FvLcCT
#NASAEarth


In a new study, scientists used #Landsat imagery from @nasa/@usgs to track shoreline changes and dramatic wetlands losses in Louisiana from 1984 to 2020.

The state lost nearly 21 square miles of important and vulnerable wetland ecosystems every year. https://go.nasa.gov/3UVZHFN

#Landsat 8 captured the image below showing harvested wheat around the town of Bereznehuvate compared to unharvested wheat around Velyka Oleksandrivka.

Satellite data help provide rapid agricultural assessments, important for markets and food security. https://go.nasa.gov/3HwH3Bs

Earth is experiencing a weak but prolonged La Niña – cooler sea surface temperatures in the tropical Pacific. 🌊

This is the third consecutive northern hemisphere winter with a La Niña, making it a rare “triple-dip” event. https://go.nasa.gov/3iW1PjR
#NASAEarth


This map of sea surface temperature anomalies on November 29, 2022 shows the signature of La Niña – a patch of cooler water (shown in blue) in the central and eastern Pacific.

Data are from a blend of @nasa, @noaa, and other satellites as well as ship and buoy observations.
