Motavelli presents evidence from 400,000 years of ice core data showing an unprecedented spike in carbon dioxide levels correlating with the industrial era. Art and Jim discuss the real-world effects already underway, from disappearing Arctic ice and migrating animal populations to island nations facing submersion. Swiss Re, the world's second-largest insurance company, has created an entire global warming department, signaling the economic gravity of the situation.
The conversation turns to geopolitical consequences, including the Pentagon report warning of potential nuclear conflict over dwindling resources by 2020.

Key Moments
Warming could trigger European deep freeze: Motavelli explains that a shutdown of the ocean conveyor belt could flip Europe from record warming to sudden cooling.
Ice cores show unprecedented CO2 spike: Motavelli says 400,000 years of ice-core data show a flat oscillation, then a sharp vertical line up beginning when humans started burning coal and combustion engines.
Emerging economies blow past Kyoto targets: Mexico projected 78% above Kyoto goals by 2010, Korea 233%, Brazil 150% - emissions from developing industrial powers dwarf treaty limits.
$5 gas would 'go kaboom' for U.S. economy: Art notes Europeans already pay $5/gallon; Motavelli says American economy would crater because the U.S. is 96% car-dependent with only 4% of trips on mass transit.
Iraqi oil fields as 'weapons of mass destruction': Motavelli reframes the WMD search: oil itself is the weapon of mass destruction, the engine of climate-driven civilizational risk.
