Understanding the Impact of Climate Change on Greenlandic Environment
Climate change poses a significant threat to the Greenlandic population and ecosystem, impacting animal and plant life, causing ice sheet melting with global consequences. Research efforts, such as measuring discharge and sediment transport, studying carbon levels, permafrost, and soil profiles, help in understanding and addressing these challenges. Changing weather patterns, vegetation period shifts affecting reindeers, and weather data further underscore the urgency of addressing climate change in Greenland.

Presentation Transcript
Why is this important? Because it can affect the Greenlandic population. It can affect the animal and plant life in the Greenlandic nature. It can cause the ice sheet to melt, wich will have a global effect.
Andreas Bech mikkelsen Copenhagen university Takes measurements of the discharge and sediment transport to get a better understanding of meltwater rivers and the glecier process
The Ice sheet Earth Earth quakes quakes Mass balance Mass balance Photos from SPRINTT
Atmospheric Carbon Levels Current level is 390 ppm -Has reached 400 ppm in the past year -Exponential Growth Curve Seasonal Fluctuation -High in winter, low in summer -Why?
The Carbon Cycle Atmosphere Permafros t Lithosphere Biosphere Soil
Permafrost What is it? -Frozen soil (> 2 years) -Gelisols- ice soils Why is it important? -Carbon store -Active layer exists on top (Cryoturbation)
Soil Profiles Remote sensing Classify areas Determine depth of permafrost Dig a soil pit (clean face) Examine layers Drill for permafrost
reindeers Sisimiut to Kangerlussuaq Vegetation period has changed Less nutrition in the vegetation less helthy milk higher death-rate on calves

Answer The Climatic changes does have an effect, but the effects are spread out over a longer period.
