In 2005 the Northern and Western Hemisphere, where the highest concentrations of CO2 exists, experienced three high velocity storms, of which the most devastating was the first titled Katrina. As a result the troposphere was less hot while the oceans warmed. The capacity for the North West Troposphere to dissipate heat into the oceans is waning due to loss of tropospheric water vapor and the melting within the Arctic Circle has accelerated.
