SST in Pacific Warm Pool (ODP site 806B, 0°N, 160°E) in past millennium. Time scale expanded in recent periods. Data after 1880 is 5-year mean. Source: Medina-Elizalde and Lea, ScienceExpress, 13 October 2005;data for 1880-1981 based on Rayner et al., JGR, 108, 2003, after 1981 on Reynolds and Smith, J. Climate, 7, 1994.

Science andamp; Implications 1. Warming andgt;1°C Risks ‘Different Planet’ - Maximum CO2 ~450 ppm - Somewhat greater if non-CO2 ↓ 2. Gas + Oil Use Most of 450 ppm Limit - Coal/unconventional must sequester CO2 - Gas + Oil supplies must be stretched 3. Quarter of CO2 Stays in Air 'Forever' - Eventual Vehicles must be Zero-CO2 (renewable, hydrogen from nuclear or solar, etc.) - Eventual Power Plants must be Zero-CO2

Inferences (Opinions) 1. Building/Vehicle Efficiencies Critical - Needed to Stretch Oil/Gas Supplies - Needed for Future Non-Carbon Energy 2. Both Incentives and Standards Needed - Rising Price on Carbon Drives Innovation - Efficiency Standards Proven Effective 3. United States Leadership Essential - Large Emissions, Tech andamp; Political Leader - Developing Countries cannot be expected to act until the U.S. Takes First Step

Slide12: 

Fossil Fuel Facts andamp; Opinions 1. Value Fossil Fuels andgt;andgt; Mining Cost - $$$$ Pocketed by Middle East andamp; Russia - Those $$$$ Fund Many Things 2. Steadily Rising Carbon Tax - Can Be Revenue Neutral - Nonpartisan Tsar Adjusts Rate (a la Fed. Res.) - Spurs Technology Devel. andamp; Efficiency - Energy Need per GDP Decreases 3. Results - Energy Independence andamp; National Security - $$$$ to U.S. Treasury, not Middle East/Russia - Improves U.S. International Competitiveness - Good High-Tech High-Pay Jobs in the U.S.
