SCIENTIFIC EVIDENCE FOR 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?

Is there scientific evidence to support anthropogenic climate change?

Post Discussion

Greenhouse gases

Fossil fuel use Melting ice

caps, extreme weather

Deforestation Sea level rise,

Greenhouse Effect

Enhanced Greenhouse Effect

Carbon Dioxide (CO2) 40% increase since

the industrial revolution

Sources: fossil fuel use, deforestation

Methane (CH4) 8x stronger effect

than CO2

Sources: energy, rice paddies, waste

Nitrous Oxide (N2O) Source: fertilizer

WHAT IS THE IMPACT OF GLOBALIZATION ON CLIMATE CHANGE?

Globalization context

Causes: Fossil fuels (Energy)

Transportation Manufacturing Electricity

Deforestation Agriculture Urbanization Natural resource

extraction Waste

Impacts: Refugees Resource shortages

Water Food

Circulation patterns Mitigation:

E.g., sea level rise Adaptation

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 self interests.

Climate change is “inconvenient” to political agendas.

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

Scientific evidence of climate change

Change: February 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)

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.
