Climate change is causing rising sea levels, longer and more intense heat waves, melting ice, extreme weather events and more.

But there are other, often surprising, ways Earth’s changing climate is affecting our world. 🧵 go.nasa.gov/3pNh4Pg
#NASAEarth

Climate change may make airline flights bumpier. 🛩️

Climate change may strengthen vertical wind shear in jet streams – creating irregular air motions, or turbulence. Pilots use or avoid jet streams to make flights more efficient.
#NASAEarth

As Arctic sea ice melts due to climate change, sailing through the Arctic Ocean could become easier and shorten travel times.

However, traveling over sea ice using snowmobiles, trucks or other vehicles could become unsafe as the ice thins. 🧊
#NASAEarth

Climate change is expected to increase the frequency and intensity of droughts and floods.

Water levels in rivers and reservoirs could shift drastically, impacting cargo ships. 🚢 go.nasa.gov/3pNh4Pg

The #ArtemisGeneration has big shoes to fill. 👞

During Apollo 11 the average age in mission control was only 28 years old. Today, @nasa is preparing for the next generation to take the helm. The Artemis generation, like Apollo before them, will guide humanity to new heights.

“We always describe water as the artery of life."

Through the @GLOBEProgram, NASA is helping create a global network of student and citizen scientists. In Oman, students are working on issues affecting local farmers, such as low water levels and soil salinity.

"Houston, Hubble has been released. It's safely back on its journey of exploration" –Scott Altman, STS-125 Commander

Space Shuttle Atlantis released the @NASAHubble Space Telescope #OTD in 2009 after the STS-125 crew made the observatory's final repairs and upgrades.

About 26,000 light-years away, the globular star cluster NGC 6325 shines in this #HubbleFriday view.

Globular clusters are tightly bound collections of stars that contain anywhere from tens of thousands to millions of members: go.nasa.gov/3WetrQu

Ever feel like you're being pulled in different directions and you might erupt?

An Earth-size exoplanet, spotted by NASA's orbiting telescopes, is at the center of a cosmic tug-of-war in its star system—which may stud its surface with fiery volcanoes: go.nasa.gov/3MzUxhS

Way to go, #CAPSTONE!

In addition to taking its first images and testing new navigational tech, the #CubeSat has flown a near-rectilinear halo orbit for over six months, the same orbit that @NASA_Gateway, our future lunar space station, will fly.

Nice work, #CAPSTONE!

Our Lunar Reconnaissance Orbiter has received and returned signal from the spacecraft which will continue testing its near rectilinear halo orbit for up to 12 months!

Zooming in on Belva Crater. Places like this, where nature has done the excavating for you, can be great for getting a look at exposed rocks from under the surface. Hooray for meteorites! ☄️

NASA Teams with Forest Service to Tally America’s Oldest Trees

The White House has called for an inventory of our eldest forests. A space instrument is helping scientists chronicle these trees as a changing climate threatens their future.
