Greenland's Melting Ice: Impact on Sea Levels and Climate Change

The video discusses the work of polar explorer John Helscher, who uses depth survey equipment to study melt lakes within the ice sheet. The research aims to estimate melt water volume, which affects ice sheet movement and sea level rise. Coastal weather observations indicate rising temperatures and increased glacier flows in Greenland. NASA's research shows a 30% increase in melt water production over 17 years, contributing to glacier acceleration. Greenpeace's expedition highlights the impact of climate change on Greenland's ice sheet, urging industrialized countries to reduce greenhouse gas emissions. If the Greenland ice sheet melts completely, sea levels could rise by up to seven meters.

What actions has Greenpeace called for in response to climate change effects on Greenland's ice?
