Answer:
Carbon dioxide raises global temperature by trapping heat that would otherwise escape directly into space. Also, warming temperatures in the Arctic may release even more carbon dioxide and other greenhouse gases such as methane, by melting frozen soil called permafrost. For example, melting glaciers and icebergs in the poles claim increasing heat.
