The cryosphere, a vital component of Earth's climate system, is undergoing rapid changes as rising global temperatures cause ice sheets to melt and sea levels to rise. Through the long-running Operation IceBridge, NASA scientists monitor these icy regions, collecting critical data on glaciers and sea ice to better understand the impacts of climate change. This mission, which includes multiple field campaigns and satellite observations, provides essential insights into the health of our planet and the potential risks to vulnerable coastal cities worldwide.
