SCIENTIFIC EVIDENCE
FOR ANTHROPOGENIC
CLIMATE CHANGE
Is there scientific evidence to support
anthropogenic climate change?
If no, how would you argue this to someone who
“believes” in climate change?
•
If yes, how would you argue this to someone
who doesn’t “believe” in climate change?

Enhanced Greenhouse Effect

Carbon Dioxide (CO2)
40% increase since the
industrial revolution
 Sources: fossil fuel use,


Methane (CH4)
8x stronger effect than

HOW WOULD YOU EXPLAIN
CLIMATE CHANGE TO A
“NON-BELIEVER”?

Why is climate change controversial?

Like evolution, climate change has become a battle
of “belief.”
 De-“sciencizes”


the issue; scientists lose authority.
Mitigation asks people to act
against their immediate
interests.
Climate change is
“inconvenient” to political
agendas.

HOW WOULD YOU EXPLAIN
CLIMATE CHANGE TO A
“NON-BELIEVER”?
Scientific evidence of climate change

Change:
2012 marks the 324th consecutive month
with a global temperature above the 20th century
average. (NOAA)
 The last month with below average temperatures was
February 1985. (NOAA)
 February

Anthropogenic change:
 Observed
warming over the last 50 years is very likely
due to the increase in greenhouse gas concentration. (IPCC)
 Fossil fuel use, deforestation, agriculture, waste.

Jig-Saw
 Before
class:
 Read
your assigned chapter
 Post on the objective of the chapter
 During
class:
 Discuss
with those that also read the
article
 Switch groups and discuss your article
with people who haven’t read it
