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
