Teaching Climate Change to Skeptics


Presentation Description

An effective way of teaching climate change is to balance risk against reward (1). Climate change is already costing us (2). Wildfires, droughts, and refugees are increasing; storms becoming more violent; floods setting record heights; and glaciers melting. If we do nothing, it could cost $ 1 trillion/year (2). Climate science tells us the risks. The stable climate for the last 10,000 years helped explode our population from 3x106 to 7x109. Our carbon dioxide emissions are warming the earth via the greenhouse effect. At the present rate of CO2 increase, concentrations will reach 700 ppm by 2100. Millions of year ago, sea levels were 300 feet higher at 700 ppm. Sea Levels could rise as much as 3 feet by 2015 and 15 feet by 2059 according to James Hansen’s paper in the Journal of Atmospheric Chemistry and Physics (March 2016). Predictions of massive flood losses for the world’s 136 largest coastal cities are US$60-$63 billion per year in 2050 compared to $6 billion in 2005. Failure to act could lead to global losses upwards of $1 trillion annually (1). REFERENCES: (1) Carmen Nobel, “Teaching Climate Change to Skeptics” Forbes. Sept 9, 2013. (2) H. Paulson, M.

Teaching Climate Change To Skeptics FORBES, Sept 9, 2013 CARMEN NOBEL, Harvard Business School The Business and Environment Initiative at Harvard Business School aims to shift the debate about climate change from a political discussion to a practical conversation about risk and reward. Even if you believe there is an 80 percent chance climate change is not man-made, the dramatic consequences make it worth trying to do something about it.

During the steepest warming, the CO 2 released (dots) from the sea preceded the global temperature rise (green line) by several centuries. CO2 RATE OF CHANGE is 1/300 of the PRESENT RISE. CO2 greenhouse effect drove the 3.5 C increase in average global temperature. Sea levels rose ~ 100 meters (~ 328 feet).

At present rate of 2.5 ppm rise per year, humans are increasing CO2 at a  rate 300 times faster than the recovery from the ice age 18,000 -10,000 years ago. CO2 CONCENTRATIONS, HIGHEST (33%) IN 800,000 YRS, WILL REACH 1000 PPM IN 240 YEARS.


The rate of sea level increase correlates with the blue line of CO2 increase. Sea level rise is a proxy for global temperature, due to thermal expansion (50%) & the melting of ice (50%) Sea level rise rate has increased 4 times: 3.1 mm/year ( 1 ft /100 yr. ) now from 0.8 mm/year in 1900 7


Sea Levels could rise as much as 3 to 15 feet in 50 to 150 years The Gulf Stream, which warms Northern Europe, will slow & shut- down. Referred 2016 Journal article Atmos. Chem. Phys. Mar. 2016 by NASA scientist James Hansen and 13 co-authors.

The Coming Climate Crash: Lessons for Climate Change in the 2008 Recession By HENRY M. PAULSON Jr. Secretary of the Treasury under Pres. George W. Bush. Co-Author of www.RiskyBusiness.org JUNE 21, 2014 http://www.nytimes.com/2014/06/22/opinion/sunday/lessons-for-climate-change-in-the-2008-recession.html “We’re staring down a climate bubble that poses enormous risks to both our environment  and economy . The warning signs are clear and growing more urgent as the risks go unchecked. A tax on carbon emissions will unleash a wave of innovation to develop technologies, lower the costs of clean energy and create jobs as we and other nations develop new energy products and infrastructure. Climate change is the challenge of our time. We’ve seen and felt the costs of underestimating the financial bubble. Let’s not ignore the climate bubble.”

STEPS FOR SUCCESSFUL CHANGE 1.Create a sense of emergency 2. Pull together a guiding team 3. Decide what to do 4. Communicate for understanding & buy-in 5. Empower others to act 6. Produce short term win 7. Don’t let up 8 Create a new culture.

CONCLUSIONS 1. WEATHER EXTREMES ARE INCREASING - Wet areas are becoming wetter: Floods, Snow Atmosphere holds more water at higher temps. -Dry areas, drier: Droughts, Wildfires 2. IF SEA LEVELS RISE BY 1 METER by 2050 WILL THERE BE ENOUGH TIME TO PREVENT A RISE TO 5 METER (15 FT) IN 2058? 3. START PHASING-OUT FOSSIL FUEL BURNING WITH CARBON FEE & DIVIDEND 15
