We don't need a time machine to learn from the past (but let us know if you find one)! Air bubbles trapped in ice for millennia and ancient pollen grains can tell us a lot about climate shifts hundreds of thousands of years ago!

Hidden beneath Greenland’s ice and powered by a nuclear reactor, Camp Century made for an interesting US military base. But life under the ice came with unique struggles; and although it wasn’t mainly constructed for science, the base...

Hank brings you news from around the universe, including what you can't blame on global warming, why being unfaithful is hazardous to your health, and how to watch a particularly awesome spectacle coming to a sky near you.

Scientists know that greenhouse gases from human activities are warming the Earth and causing major changes in the environment. Dr. Jennifer Francis explains that for thousands of years, Earth’s temperature was mostly stable due to...

ANTARCTICA ANTARTICA IS A STOREHOUSE OF EARTH HISTORY AND CONTAINS MANY CLUES ABOUT ITS POSSIBLE FUTURE. STUDYING SECTIONS OF ICE CORE GOING BACK 800,000 YEARS, SCIENTISTS AT THE BRITISH ANTARCTIC SURVEY HAVE COME TO SOME STARK...

Ice cores taken from deep within the Earth's polar regions hold a hidden secret: the historical record of the Earth's climate. Earth Science - Human Impacts - Learning Points. Evidence of natural climate changes can be found in...

How climatologists use ice cores, cylindrical cones of ice drilled from glaciers, to reveal Earth's historical cycles of climate change. Earth Science - Human Impacts - Learning Points. The Earth has natural, long cycles of climate. The...

Brit looks back on our first month on Nature League, when we explored the theme of life on Earth.

It's a freezing cold day inside the National Ice Core Laboratory (NICL) in Denver, Colo., as it is every day of the year. That's because the NICL is a facility for storing and studying ice cores recovered from the polar regions of the...

Life on the ice is extremely different from life around your own home town. Scientists work long days often without taking time for a break. When the research teams have time for rest and relaxation, they have to come up with creative...

At the Stable Isotope Lab in Boulder, Colo., scientists are doing a lot of the same things that those CSI folks do on TV. But instead of being "crime scene investigators," these experts are more like "cold scene investigators."...

According to new research, a powerful volcanic eruption in modern-day Alaska around 44 B.C. may have contributed to the Roman Republic’s downfall on the other side of the globe.
