what is the significant of attic tundra

The arctic tundra plays a significant role in maintaining sea levels and regulating global greenhouse emission. If the arctic tundra melts, then sea levels will rise considerably. It will also contribute to the releases of greenhouse gases. The arctic tundra contains a lot of organic material trapped inside the ice. If it melts, it will release carbon dioxide and methane, which will increase the amount of greenhouse gas in the atmosphere.
