Quantitative Literacy and Global Warming

Key Connections:

  • Logic and critical thinking
  • Data interpretation and visualization
  • Mathematical modeling
  • Economic considerations
  • Probability/Risk Analysis

A tale of two planets…

470°C (880°F) 15°C (59°F)

A tale of two planets…

470°C (880°F) 15°C (59°F) Distance alone can’t explain it…

In fact: Venus absorbs less sunlight than Earth (because of its reflective clouds) so “should” be cooler!

The Greenhouse Effect

Net Result: Added Energy (Heat) in Lower Atmosphere

How do we know the greenhouse effect is real?

Test 1: Laboratory measurements (since 1859! Test 2: Compare predicted and actual planetary temperatures

Without the greenhouse effect, Earth would be too cold for life!

A tale of two planets…

470°C (880°F) 15°C (59°F)

So the greenhouse effect is a very good thing for life!

Enough carbon dioxide to make our planet livable.

Too much of a good thing!

~200,000 times as much carbon dioxide as Earth.

The Rising CO2 Concentration The Rising CO2 Concentration What about before 1958?

800,000 Years of CO2 800,000 Years of CO2

  • CO2 today: ~40% higher than in past 800,000 years
  • On track to: double pre-industrial value in 50 to 60 years…
  • triple that value by mid next century…

“Global Warming 1-2-3”

  • 1. FACT: Carbon dioxide (a “greenhouse gas”) makes

Earth warmer than it would be otherwise.

“Global Warming 1-2-3”

  • 1. FACT: Carbon dioxide (a “greenhouse gas”) makes

Earth warmer than it would be otherwise.

  • 2. FACT: Use of fossil fuels (coal/oil/gas) is adding

carbon dioxide to the atmosphere.

“Global Warming 1-2-3”

  • 1. FACT: Carbon dioxide (a “greenhouse gas”) makes

Earth warmer than it would be otherwise.

  • 2. FACT: Use of fossil fuels (coal/oil/gas) is adding

carbon dioxide to the atmosphere.

  • 3. CONCLUSION: We expect global warming to occur.

What we are now doing to the world … by adding greenhouse gases to the air at an unprecedented rate… is new in the experience of the Earth. It is mankind and his activities which are changing the environment of our planet in damaging and dangerous ways. — British Prime Minister Margaret Thatcher, Nov. 8, 1989

(in a speech to the United Nations)

Existing Technologies:

  • Efficiency

e.g., incandescent bulbs waste 95% of energy input

  • Renewables

e.g., solar power reaching Earth is 20,000 times current world power usage

  • Nuclear

new, safer technologies, with less waste

CA energy from fossil fuels today ≈ 66% with closed/canceled nuclear ≈ 27%

A Solvable Problem

Future Technologies:

  • Algae-based biofuels
  • r bacteria that remove CO2 from air
  • Solar energy from space

  • Nuclear fusion

water from one kitchen faucet could power U.S.

  • Environmental damage from spills, strip mines

IMF 2015: global subsidy ~ $4 trillion/yr (US ~$1 trillion/yr) Note $1 trillion ≈ $3000/person in USA
