Greenland Ice Cap - New Evidence Discovered

The video explores the rapid changes occurring in the Arctic, particularly focusing on the Greenland ice sheet and Jakobshavn Glacier. It highlights the alarming rate of ice cap reduction and its contribution to sea level rise, driven by global warming. Scientists are studying the melt patterns and dynamics of the ice sheet, using seismic testing and observing the effects of cryoconite, a dark industrial dust that accelerates melting. The Arctic serves as an early warning system for global climate change.

What is the primary factor contributing to the rapid retreat of the Greenland ice sheet?

• Ocean currents

• Deforestation

• Global warming

• Increased volcanic activity

Which glacier is noted as the most active in the world and a major contributor to sea level rise?

• Jakobshavn Glacier

• Petermann Glacier

• Helheim Glacier

• Kangerlussuaq Glacier

What method are scientists using to study the dynamics beneath the Greenland ice sheet?

• Satellite imaging

• Thermal cameras

• Underwater drones

• Seismic testing

What is cryoconite, and how does it affect the ice sheet?

• A type of algae that cools the ice

• A form of industrial dust that accelerates melting

• A natural mineral that strengthens the ice

• A type of snow that insulates the ice

Why is the Arctic considered an early warning system for global climate change?

• It is the most isolated region

• It has the largest icebergs

• It is the coldest region on Earth

• Changes there occur faster than elsewhere
