Using radar and other techniques, researchers have mapped out the sediments left by a lake that apparently existed before Greenland was glaciated. Next step: drilling through the ice to see what they contain.

In a new book, glaciologist Marco Tedesco takes the reader on a personal journey through his sometimes dangerous work.

In a new study, researchers have proposed a mechanism for how mega-canyons under northern Greenland’s ice sheet formed: from a series of catastrophic outburst floods that suddenly and repeatedly drained lakes of melting ice-sheet water.

While much of the world is planning for flooding and inundation from changes in sea level, Greenland is facing a much different future.

Rainy weather is becoming increasingly common over parts of the Greenland ice sheet, triggering sudden melting events that are eating at the ice and priming the surface for more widespread future melting, says a new study.

For this early part of the season the goal is to tease apart a record of historic precipitation and temperature for this region using isotopes from leaf waxes collected in the lake sediments.

Polar scientists Marco Tedesco and Robin Bell provide a primer on how climate change will impact our coastlines.

Iron particles catching a ride on glacial meltwater washed out to sea are likely fueling a recently discovered summer algal bloom off the southern coast of Greenland, according to a new study.

Microalgae, also known as phytoplankton, are plant-like marine microorganisms that form the base of the food web in many parts of the ocean. “Phytoplankton serve as food for all of the fish and animals that live there. Everything that eats is eating them ultimately,” said Kevin Arrigo, a biological oceanographer at Stanford University and lead author of the study.

The Arctic is warming twice as fast as the rest of the planet, and scientists are seeing the effects across ice and ecosystems. The average annual air temperature over Arctic land is now 3.5°C (6.5°F) warmer than it was 1900, Greenland is experiencing longer melting seasons, and this year’s spring snow cover extent set a record low in the North American Arctic, according to the National Oceanic and Atmospheric Administration’s newly released 2016 Arctic Report Card.

Following record-high temperatures and melting records in northwest Greenland in summer 2015, a new study provides the first evidence linking melting in Greenland to the anticipated effects of a phenomenon known as Artic amplification.

Nicolás Young was just named a winner of a 2015 Blavatnik Award for his work measuring ice sheets in changing climates of the past and their contribution to sea level rise. His new projects are taking glacier tracking to the next level.

The end of the recurring, 100,000-year glacial cycles is one of the most prominent and readily identifiable features in records of the Earth's recent climate history. Yet one of the most puzzling questions in climate science has been why different parts of the world, most notably Greenland, appear to have warmed at different times and at different rates after the end of the last Ice Age.
