From airplanes
high above the South Pole to satellites
in orbit, #NASAExplorers
investigate some of Earth's coldest places to learn more about our changing planet. Join them in @NASA's digital series! Watch

Join
#NASAExplorers
on the coldest game of tag ever played. A satellite
and an airplane
chase each other through the night skies over Antarctica
to measure the changing height
of ice on our warming
planet.

It may be
#polarvortex cold
in parts of the United States right now, but #Australia is sweating through a sweltering summer.

The dark of a September morning
is suddenly illuminated by rocket fire
. For some #NASAExplorers
, it’s the culmination of a decade’s work designing, building and launching #ICESat2
for a global view
of our changing planet.

Ice can be a time
machine. The Arctic’s frozen soil, permafrost, holds dead plants
& animals from thousands of years of ago. Join #NASAExplorers
on a trip underground
— and through time — to learn what happens as permafrost thaws.

High in the mountains
, temperatures stay icy year-round and rivers of ice — glaciers — flow down into lower altitudes, providing an important source of freshwater
. #NASAExplorers
study how these glaciers respond to a warming planet.

From Earth into the solar system, water ice

is out there. On other planets and moons
, it can be a good starting point in the #SearchForLife
. #NASAExplorers
are looking
at the cryosphere on Earth and beyond.

#ICESat-2 does more than measure polar ice. It also makes detailed observations of elevation in tropical and temperate latitudes. This is what the#satellite observed as it passed over a forested hillside in#Mexico. https://earthobservatory.nasa.gov/images/144450/icesat-2-sees-the-trees-in-mexico …#NASApic.twitter.com/59FwyU1tYI

Ice sheets and glaciers
in Greenland and Antarctica store more than 99% of Earth’s freshwater
ice. This ice is melting, and #NASAExplorers
are investigating how it raises sea levels
as it makes its way from land to the ocean.

Radar data from NASA airborne
and new international satellite missions
helped researchers discover the gigantic cavity which is big enough to have contained 14 billion tons of ice, and most of that ice melted over the last three years. @NASA_ICEpic.twitter.com/CuWsqCUq4HShow this threadThanks. Twitter will use this to make your timeline better. UndoUndo -
About the size of Florida, Thwaites Glacier is currently responsible for approximately 4% of global sea level rise

It holds enough ice to raise the world ocean over 2 ft & backstops neighboring glaciers that would raise sea levels an additional 8 ft if all the ice were lost.Show this threadThanks. Twitter will use this to make your timeline better. UndoUndo
