Arlington, Va.— "GeoSystems: Probing Earth's Deep-Time Climate and Linked Systems" focuses on "deep-time" millions of years ago to better understand the complexities of Earth's atmosphere, water, ecosystems, and geology, using climate as the focus.

National Science Foundation (NSF) and university scientists will participate in a workshop highlighting recent "deep-time" discoveries. Their presentations will address the status, role and future of deep-time climate and linked studies, and the lessons we can learn from shining a light into Earth's deep-time dark ages.

Aspects of our modern climate are now returning to a state last known eons ago. Understanding the ranges, rates, and processes responsible for climate extremes in those ancient times is critical for developing knowledge of our planet's climate system, and for predictions of future climate scenarios.

Recent research on deep-time is changing previous conceptions by reconstructing parameters such as atmospheric composition, sea-surface temperature, rates and modes of ocean circulation, ocean state (oxygen levels, nutrient status, biological productivity), winds, seasonality, and temperatures from records dating from tens, hundreds, and thousands of millions of years in the past. These records, scientists say, are teaching us how Earth's past climate interacted with its ecosystems, geology and water in ways previously unimagined.

The U.S. National Science Foundation propels the nation forward by advancing fundamental research in all fields of science and engineering. NSF supports research and people by providing facilities, instruments and funding to support their ingenuity and sustain the U.S. as a global leader in research and innovation. With a fiscal year 2022 budget of $8.8 billion, NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and institutions. Each year, NSF receives more than 40,000 competitive proposals and makes about 11,000 new awards. Those awards include support for cooperative research with industry, Arctic and Antarctic research and operations, and U.S. participation in international scientific efforts.
