What is geoscience?

Geoscience (also called Earth Science) is the study of Earth. Geoscience includes so much more than rocks and volcanoes, it studies the processes that form and shape Earth's surface, the natural resources we use, and how water and ecosystems are interconnected. Geoscience uses tools and techniques from other science fields as well, such as chemistry, physics, biology, and math! Read more...

The Arctic island of Svalbard is so reliably frigid that humanity bet its future on the place. Since 2008, the Svalbard Global Seed Vault — set deep in frozen soil known as permafrost — has accepted nearly 1.4 million samples of more than 6,000 species of critical crops. But, the island is warming six to seven times faster than the rest of the planet, making even winters freakishly hot, at least by Arctic standards. Indeed, in 2017, an access tunnel to the vault flooded as permafrost melted, though the seeds weren’t impacted.

This February, a team of scientists was working on Svalbard when irony took hold. Drilling into the soil, they gathered samples of bacteria that proliferate when the ground thaws. These microbes munch on organic matter and burp methane, an extremely potent greenhouse gas and significant driver of global warming. Those emissions are potentially fueling a feedback loop in the Arctic: As more soil thaws, more methane is released, leading to more thawing and more methane, and on and on.
