NASA Explorers: Cryosphere - The Big Thaw

TL;DR

NASA explores the cryosphere, the frozen parts of the Earth, and its impact on climate change through satellite missions, field research, and monitoring.

Transcript

Here at the end of the Earth it still feels like a place for raw exploration and adventure. It’s vast in all directions and ground zero for some of the biggest questions we have about the climate. But when we decided to make a series about the frozen places on Earth, we knew there would be one hurdle we’d need to jump over first: What is the cry... Read More

Key Insights

• 🥶 The cryosphere includes various types of frozen elements, such as sea ice, snow cover, permafrost, glaciers, and ice sheets.
• 🫠 Rising sea levels caused by cryosphere melting can displace millions of people around the world.
• 👨‍🔬 NASA plays a crucial role in studying and monitoring the cryosphere through satellite missions, field research, and collaboration with scientists.
• 🪐 The cryosphere's changes have significant implications for climate patterns, ecosystems, and the overall balance of the planet.
• 🎟️ NASA's missions, including GRACE Follow On and Operation IceBridge, provide valuable data for understanding cryosphere changes.
• 😥 The cryosphere is at a near tipping point, and urgent action is needed to mitigate the impacts of climate change.
• 🫠 The cryosphere's melting contributes to the loss of habitats for polar species and threatens biodiversity.

Questions & Answers

Q: What is the cryosphere, and why is it significant?

The cryosphere refers to the frozen parts of the Earth, including ice sheets, glaciers, and sea ice. It is significant because it affects climate patterns, sea levels, and polar ecosystems.

Q: How does the cryosphere contribute to rising sea levels?

As the cryosphere melts, it adds water to the oceans, resulting in sea level rise. Estimates suggest that sea levels could rise by one to three feet in the next century, potentially displacing millions of people.

Q: How does NASA study the cryosphere?

NASA uses satellite missions like GRACE Follow On and Operation IceBridge to track water movement and monitor changes in the cryosphere. They also conduct field research and collaborate with individual researchers and labs.

Q: What are the potential consequences of a rapidly changing cryosphere?

A rapidly changing cryosphere can lead to the loss of habitats for polar species, increased coastal flooding, disruption of ocean currents, and changes in weather patterns worldwide.

Summary & Key Takeaways

• The cryosphere includes sea ice, snow cover, permafrost, glaciers, and ice sheets, and it plays a significant role in climate change and rising sea levels.

• NASA's Cryospheric Program Scientist is responsible for monitoring the cryosphere and its current status.

• NASA studies the cryosphere through various missions, including satellite observations, airborne observations, and ground research.
