THE PERFECT STORM
INDICATIONS OF GLOBAL CLIMATE CHANGE
 Day

 Take Notes! – You will write a significant
paper on global warming – due Friday
 You will have adequate time to review
the data and construct your response.
 Failure to comply will earn you an F
grade for this assignment!
INDICATIONS OF GLOBAL CLIMATE CHANGE



Open water appears around the Arctic in Summer
2006 – 2008
Possible to pilot a ship from the Atlantic to the
Pacific without going through Panama
Children born today may face hardships created by
a warming world – food supplies will be diminished,
many forests will be destroyed, the oceans will
acidify, coastlines will change & wetlands will
disappear
CLIMATE CHANGE




Climate change introduced to U.S. Senate in 1988
– rising global temperature due to CO2 and other
greenhouse gases
UN Framework Convention on Climate Change in
Rio de Janeiro
Kyoto Protocol on reducing greenhouse gases
through emission limits in 1997
Fossil fuel interests mobilized counterattack in
1990s
CLIMATE CHANGE
Climate negotiators at the Hague met to
finalize Kyoto Protocol in 2000
 Under pressure from the oil industry
(according to one side of the argument),
George W. Bush rejected the Kyoto
Protocol
 Global emissions of CO2 from fossil fuel
combustion and cement production rose
from 22.6 billion tons in 1990 to 31 billion
tons in 2007


From 1990 – 2008, U.S. emissions grew by 27%
while emissions in China grew by 150% as they
entered intensive economic development –
China now largest emitter
Tropical deforestation is adding 6.5 billion tons
of CO2 to the atmosphere annually
Some claim the planet is near the tipping point
when climate change feed on itself and
becomes irreversible for centuries
With melting Arctic & Greenland ice and tundra,
more CO2 will be released

Millions living in the Asian mega-deltas will face
food shortages and increased exposure to
disease
In 2008 many U.S. governors met to commit to
develop a national climate policy – and 27 major
corporations announced caps for greenhouse
emissions
China announced an energy efficiency program
in 2008
CLIMATE CHANGE – 10 CHALLENGES




Thinking Long-term – climate change is longterm & must be dealt with accordingly
Innovation – develop technologies that
maximize use of carbon-free energy
Population – address expanding global
population
Changing Lifestyles – smaller houses and cars,
reduced world travel and move away from
meat with every meal
10 CHALLENGES
Healing Land – reverse flow of
greenhouse gases with more vegetation
 Strong Institutions – Give power to
international groups to control emissions
(at what cost to individual freedom?)
 Equity Imperative – Richer countries bear
the cost to reverse greenhouse gases
 Economic Stability – Climate change must
continue in weak as well as strong
economic cycles

10 CHALLENGES
Political Stability – control wars and terrorism
in order to be able to focus on global
warming
 Mobilizing for Change – overcome high cost
of reversing climate change by seeing it as
an opportunity for creating industries and
jobs

SCIENCE LITERACY
FHS students will take on an STS (Science,
Technology & Society) project in 2013 using
State of the World 2002, 2009 & 2012 as
guides
 Students will research global warming
 Students will explain their findings in a
written document to complete their project

SCIENCE LITERACY



FHS students will get involved in discussions both
in favor of taking action to slow and prevent global
warming and against such action based on their
findings
What is politically motivated conjecture vs actual
science?
Students will research natural causes for
greenhouse gases as well as those generated by
humans

I am convinced that the people of Earth
must take action to prevent an inevitable
global warming catastrophe
I think global climate change is a natural
consequence of living on planet Earth
I am a member of the U.S. Senate and I
need to be convinced one way or the
other (maximum 6 students)
