Climate Science in Action

From researching the pace of Alaskan glacier melt to how changes in Arctic sea ice affect our weather, climate scientists go to some of the most remote areas on Earth to help us understand our environment. The Juneau Icefield Research Program (JIRP) brings scientists and students together annually to study glaciers. Jeff Barbee reports on…

Scientists’ Concerns Challenge Conservative Sea-Level Rise Projections


Published on YouTube Dec 5, 2013: The most sobering evidence of the planet’s response to greenhouse gases comes from the fossil record. New evidence scientists are collecting suggests that ice sheets may be more vulnerable than previously believed, which has huge implications for sea level rise.

Each degree of global warming might ultimately raise global sea levels by more than 2 meters

By PIK: 07/15/2013 – Greenhouse gases emitted today will cause sea level to rise for centuries to come. Each degree of global warming is likely to raise sea level by more than 2 meters in the future, a study now published in the Proceedings of the National Academy of Sciences shows. While thermal expansion of…

Does Freshwater Runoff in the Arctic change Ocean Circulation to Unlock Methane Hydrate in the Deep Ocean?

Recently freshwater intake into the Arctic Circle have changed ocean currents, in the following a collection of related science, and what if freshwater currents drive warmer water into the deep ocean and unlock methane hydrates? Mechanism have been identified recently. Arctic freshwater input into the North Pacific could serve as a catalyst for methane hydrate…
