Climate Change and Sea Level Rise: The Observations “Normal” variability: - global temperature: 0.2 C/century (-0.5 to 0.5) - global sea level: 1.5 m/century (-6.0 to 6.0) o 20th century: - global temperature: 0.7 C - global sea level: 0.2 m o Syndrome

Expected Future Changes Example Hampton Roads Today’s rate: 5 mm per year (about 1.5 feet in 100 years) Soon could get as high as: 20 mm per year (about 6 feet in 100 years) Modified from Church et al. (2010) Prognosis

An Unparalleled Challenge for Humanity? Lovelock (and many others): - Planet is on a run-away path; could reach a warm state (5 C warmer) already in 2050 Australia China USA Germany Lovelock: - Carrying capacity of the planet would be reduced to 1 Billion - Recommendation: look for the lifeboats Prognosis
An Unparalleled Challenge for Humanity? Are we on Titanic after it hit the iceberg? Captain E.J. Smith: “I cannot imagine any condition which would cause a ship to founder. Modern shipbuilding has gone beyond that.” There were lifeboats for about half of the passengers, but only 1/3 made it into them - I hope, we can do better. Prognosis

Responding to the Challenge What Could be this Fundamental Change? Millennium Development Goals (2005-2015): Mostly not reached Sustainable Development Goals (2015-2025): Proposed, look very good ... SDGs: 1 Thriving lives and livelihoods 2 Sustainable food security 3 Secure sustainable water 4 Universal clean energy 5 Healthy and productive ecosystems 6 Governance for sustainable societies Griggs et al., 2013 Therapy
Responding to the Challenge Sustainable Development: Brundtland et al., 1987: “Development that meets the needs of the presence without compromising the ability of future generations to meet their needs” Griggs et al., 2013: “Development that meets the needs of the presence while safeguarding Earth’s life-support system, on which the welfare of current and future generation depends” Griggs et al., 2013 Economy is the link between humanity and Earth’s life support system Plag et al., 2013 Therapy
Responding to the Challenge Economy is the link between humanity and Earth’s life-support system An economy that meets our needs by burning fossil fuels and destroying Earth’s life-support system is like a doctor who practices medicine by killing the patients. Economy for humanity: “An economy that meets our needs while safeguarding Earth’s life-support system, on which the welfare of current and future generations depends.” Plag et al., 2013 Therapy
