Al Gore in 2007 talking about the North Polar ice cap: "One study estimated that it could be completely gone during summer in less than 22 years. Another new study, to be presented by U.S. Navy researchers later this week, warns it could happen in as little as 7 yearsβ. ...17 summers later there is more ice than a decade ago.

Why CO2 can't cause runaway global warming: The plots below show how radiation absorption & atmospheric warming (i.e. the "greenhouse effect") from added CO2 quickly diminishes at higher concentrations. Any miniscule warming from additional CO2 at this point would only benefit a world stuck in 2.5 million year ice age.
