This document discusses climate change and carbon dioxide levels. It notes that CO2 levels have risen steadily over several decades according to the Keeling Curve. Burning fossil fuels releases billions of tons of CO2 into the atmosphere each year from activities like driving gasoline-powered vehicles and coal combustion. Effects of rising temperatures include melting ice, rising sea levels, and species extinction. The 350.org movement aims to limit CO2 levels to 350 parts per million by 2100 through local events and actions that raise awareness of the target number. One such action discussed is an event on Buffalo Mountain to engage the community on addressing climate change through sustainable living.

6. FOSSILIZED PLANTS
The carbon of hundreds of
millions of summers
Ancient forests, algae and
phytoplankton became
today’s buried carbon
mined and emitted into

8. HISTORICAL CO2 LEVELS

9. 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

10. Water vapor
Methane
CO2
nitrous oxide

11. EFFECTS OF CLIMATE CHAOS
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

12. 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?

13. 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

14. 350.ORG STARTS THE TALK

15. 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

16. 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
