Arctic ice cap melt could release vast amounts of methane

The video discusses the impact of warming on Arctic ice depletion, highlighting the role of methane and carbon dioxide in trapping heat. It details the rapid shrinkage of the Arctic ice cap from 2003 to 2010 and explains how rising temperatures lead to permafrost melting, releasing methane. The video also covers the melting of ocean floor permafrost, which further contributes to methane release, exacerbating the retreat of the Arctic ice cap.

What are the main gases responsible for trapping sunlight in the Earth's atmosphere, contributing to Arctic ice depletion?

• Oxygen and Nitrogen

• Methane and Carbon Dioxide

• Hydrogen and Helium

• Argon and Neon

Between which years did the Arctic ice cap experience a rapid retreat, according to the video?

• 2010 to 2015

• 2000 to 2005

• 2003 to 2010

• 1995 to 2000

How much did the Arctic ice cap shrink from its previous low in 2007?

• 10,000 square miles

• 27,000 square miles

• 50,000 square miles

• 100,000 square miles

What happens to permafrost microbes as temperatures rise?

• They consume dead matter and release methane

• They freeze and become inactive

• They migrate to colder regions

• They convert methane into oxygen

What is released from the ocean floor as warmer seas melt permafrost?

• Carbon Dioxide

• Nitrous Oxide

• Methane Hydrate

• Sulfur Dioxide
