CARBON DIOXIDE

FOSSILIZED PLANTS
The carbon of hundreds of millions of summers
Ancient forests, algae andphytoplankton becametoday’s buried carbonmined and emitted into today’s atmosphere in ahundred years
CO2 LEVELS RISING
The Keeling Curve showing seasonalfluctuations each yrand a steady increasein CO2 levels overfour decades of study
HISTORICAL CO2 LEVELS
CARBON-DEPENDENT CIVILIZATION
A gallon of gas is 87% carbon (5 pounds). This combines with O2 when burned, results in 20 pounds of CO2 per gallon
Coal produces from 1.4 to 2.8 tons of CO2 for each ton burned
Worldwide billions of tons are burned each year
Water vapor
Methane
CO2
nitrous oxide
ozone
melting arctic ice and glaciers
rise in sea levels
species extinction especially northern
unpredictable shifts in rainfall and temperature
emergent diseases (mosquitos, ticks)
climate refugees
EFFECTS OF CLIMATE CHAOS
OH YEAH? & SO WHAT?
Is the planet’s climate warming?
Is the warming due to CO2?
Is the increased CO2 man-made?
IF YES, THEN WHAT SHOULD WE DO ABOUT IT?
SET SUSTAINABLE CO2 LIMITS
New evidence: 450 ppm by 2100 set by Kyoto too high
350 ppm: we can limit change to 2 degrees C (now 386!)
Most people don’t know how to tell when the planet is ill
Bill McKibben and 350.org: get the NUMBER known around the world by conducting “actions” that feature 350 in “iconic places” of your region
350.ORG STARTS THE TALK
FLOYD’S ACTION: OCT 10
Feature Buffalo Mountain
Include all ages and kinds of folks
encourage media coverage
make a global issue locally relevant
be represented at UN on Oct 24
WHAT GOOD MAY COME...
Reducing our CO2 footprint (and water and energy and ...) * local foods, forest products, services reduce gas and oil needs/CO2
Thinking about how much is enough. More/newer isn’t always better.
Thinking sustainable versus disposable
Stimulate creative problem solving to make life richer and the planet resilient and healthy for future generations: communities working toward an environmentally sound and socially just future
