The long view

Human and Natural Drivers of Climate Change

The Long View

CO2, CH4 and N2O Concentrations

- far exceed pre-industrial values

- increased markedly since 1750

due to human activities

Relatively little variation before

the industrial era

And the sea level is rising

And the Sea Level is Rising

Greenhouse effect

Greenhouse Effect

What are the greenhouse gases

What are the Greenhouse Gases?

  • Carbon Dioxide (CO2)

  • Methane (CH4)

    Principal Source: Burning of Fossil Fuels:

    Oil, natural gas/methane, coal

    Hydrocarbons (CnHm)) + Oxygen (O2)  CO2 + H2O

    Also Nitrous Oxide (N2O)

    Chlorofluorocarbons (CFCs)

The concentration of co2 is growing

Direct observation of recent climate change

Direct Observation of Recent Climate Change

At continental, regional, and ocean basin scales, numerous long-term changes in climate have been observed. These include:

  • Changes in Arctic temperatures and ice,

  • Widespread changes in precipitation amounts, ocean salinity, wind patterns

  • and aspects of extreme weather including droughts, heavy precipitation, heat waves and the intensity of tropical cyclones

Declining sea ice

Impacts worldwide

Impacts Worldwide

Spreading disease

Coral reef bleaching

Heat waves and periods of unusually warm weather

Downpours, heavy snowfalls, and flooding

Glaciers melting

Earlier spring arrival

Plant and animal range shifts and population declines

Sea level rise and coastal flooding

Arctic and Antarctic warming

Droughts and fires

GLOBAL WARMING: Early Warning Signs

Fingerprints and Harbingers

Why not natural gas

Why Not Natural Gas?

Natural gas causes more global warming but less air pollution mortality than coal over 150 years due to less sulfate (a cooling agent) and more methane (a warming agent) from natural gas than coal. Coal causes higher mortality.

50-70 times more CO2 and air pollution per kWh

than wind

Hydrofracking causes land and water supply degradation

Why not nuclear

Why Not Nuclear?

9-25 times more pollution per kWh than wind from mining & refining uranium, using fossil fuels for electricity during the 11-19 years to permit (6-10 y) and construct (4-9 y) nuclear plant compared with 2-5 years for a wind or solar farm

Risk of meltdown (1.5% of all nuclear reactors to date have melted)

Risk of nuclear weapons proliferation

Unresolved waste issues

Why not ethanol

Why Not Ethanol?

Corn and cellulosic E85 cause same or higher air pollution as gasoline

-- Corn E85: 90-200% of CO2 emissions of


-- Cellulosic E85: 50-150% of CO2 emissions of


Wind: <1% of CO2 emissions as gasoline

Enormous land use and water requirements

Wind Electricity

  • Effort needed by 2055 for 1 wedge:

  • One million 2-MW windmills displacing coal power.

    • Today: 50,000 MW (1/40)

Nuclear electricity

Nuclear Electricity

Effort needed by 2055 for 1 wedge:

700 GW (twice current capacity) displacing coal power.



Phase out of nuclear power creates the need for another half wedge.

A revised goal: retrievable storage

Natural-U plants (no enrichment), no reprocessing

Universal rules and international governance

Effort needed by 2055 for 1 wedge:


25% reduction in expected 2055 electricity use in commercial and residential buildings

Target commercial and multifamily buildings.

Efficient Use of Fuel

Effort needed by 2055 for 1 wedge:

Note: 1 car driven 10,000 miles at 30 mpg emits 1 ton of carbon.

2 billion cars driven 10,000 miles per year at 60 mpg instead of 30 mpg.

2 billion cars driven, at 30 mpg, 5,000 instead of 10,000 miles per year.

  • Property-tax systems that reinvigorate cities and discourage sprawl
