Alaska mountain glaciers retreating due to climate change - Science Nation

Tighten your seat belt! This runway is made of ice. Welcome to the Ruth Glacier, deep inside Alaska's Denali National Park. Many of the visitors are here for backcountry skiing, but this is no vacation for University of Maine paleoclimatologist Karl Kreutz and his team. For them, time on the ice is all part of the job. With support from the National Science Foundation (NSF), the scientists are working to reconstruct the climate history of this area over the last thousand years. They're researching the relationship between the temperatures and precipitation rates, and the response of glaciers in this area to climate changes. In 2013, the team drilled ice cores high atop Denali's Mount Hunter. By carefully analyzing ice layers inside the cores, the team is developing a record of temperature change in the Alaska range over the last millennium. While the vast majority of glacier ice on our planet lies in Greenland and Antarctica, Kreutz says the glaciers in Alaska could also make a significant contribution to global sea-level rise in the coming decades. The research in this episode was supported by NSF award #1203838, Collaborative Research: Paleo Perspectives on Climate Change (P2C2)--Reconstructing Central Alaskan Precipitation Variability and Atmospheric Circulation during the Past Millennium. This collaboration between Erich Osterberg (award #1204035, Dartmouth College, lead), Cameron Wake (award #1203863, University of New Hampshire) and Karl Kreutz (award #1203838, University of Maine) will continue work begun under Wake's previous PLR grant #0714004: COLLABORATIVE RESEARCH: Drillsite Reconaissance and Snow Chemistry Survey in Denali National Park.

Joseph P Trantas, Sr. https://youtu.be/DfpszyaqLCc i need your help please watch pt-1 and pt-2 very important !!!!!! also dr john holdren thank you if I have to watch one more video of all these experts talking about greenhouse gases I'm going to explode I am showing something with greenhouse gas that is 10 times bigger than their story but no one is looking at this it drives me crazy how could you talk about this without looking at my research please take the time to watch the video I posted this problem must come to the front of all conversations pertaining to climate change study especially greenhouse gases thank you
