Frank Capra, 1958

CO2 collects in Troposphere

  • Ozone O3 layer – absorbs ultraviolet radiation from sun
van allen radiation belts
Van Allen Radiation Belts

Magnetic field of Earth creates radiation belts.

These protect us from particles flying at Earth via solar wind (stream of ionized gases at 400 km/sec)

atmospheric co 2 ppm mauna loa observatory
Atmospheric CO2ppmMauna Loa Observatory

24% increase in 50 years

co 2 equivalents aka co 2 e
CO2 equivalents, aka CO2e
  • How does the global warming potential (GWP) of a gas compare to CO2
  • CO2, by definition has GWP = 1.0

IPCC AR4 p. 212

  • SF6 - 8,000 tons produced per year
    • 6,000 in electrical industry, inert gas for casting magnesium
    • Inert filling for insulated glazing windows
  • 0.2% of GHG emissions
slide17
IPCC
  • Intergovernmental Panel on Climate Change
    • United Nations Environmental Programme
    • World Meteorological Organization
  • 1988 mission: assess risks and impacts of climate change
    • Comprehensive, open, objective, transparent, scientific understanding of human-caused climate change
  • Assessment reports: 1990, 92, 95, 01, 07
  • Over 90% of change in temps caused by humans
  • 2500 scientific expert reviewers, 800 authors
how much agreement
How Much Agreement?
  • Proceedings of National Academy of Sciences
  • 1,372 Climate Researchers’ publication and citation data
    • 97-98% most actively publishing support tenets of ACC outlined by IPCC
    • scientific prominence of the researchers unconvinced of ACC are substantially below that of the convinced researchers
the earth s rotation
The Earth’s Rotation
  • CO2
    • 280 ppm for human history
    • Last 250 years up to 384 ppm – where we are now
  • Milankovich Cycles (pp 117-8):
    • Earth’s orbit not circular, 100,000 year cycle
    • Tilted axisshifts: 40,000 year cycle
    • Plane of orbit relative to sun: 21,000 year cycle
    • Seems unlikely
climate models
Climate Models
  • We’re at 384 ppm
  • 450 ppm would be 2°C increase
  • 550 ppm would lead to 3° C increase
    • Used to be target
    • Pests not killed by freezes
    • Ice sheets melting faster than predicted
    • Oceans more acidic than thought
    • China’s growing faster than expected
  • 350? Really hard
global weirding
Global Weirding
  • Atlanta
    • Water shortage? Why more than used to?
  • Montana:
    • Elk season had to be moved
    • No trout in the streams
    • Snowcaps in August gone
  • Higher temperatures increase evaporation
    • Soils drying out
  • More water in the atmosphere, has to come down
    • Means when it rains, it pours, more huge downpours
  • Changing wind patterns
  • Search “cities hardest hit by climate change evaporation” Nevada came up first:

public opinion
Public Opinion

In the US, it’s a political issue, so there must be two sides?

one politician
One Politician
  • “If ninety-eight doctors say my son is ill and needs medication, and two say, “No, he doesn’t, he is fine,” I will go with the ninety-eight. It’s common sense – same with global warming. We go with the majority, the large majority.”
  • Arnold Schwartzeneger
    • Quoted in Thomas Friedman, (2009)“Hot Flat, and Crowded,” pp. 178-9.
rupert murdoch
Rupert Murdoch
  • Climate change poses clear, catastrophic threats. We may not agree on the extent, but we certainly can't afford the risk of inaction.
  • We must transform the way we use energy, and of course not only because of climate change...
  • When I look around the world today, I see continued dependence on oil from vulnerable regions... and oil money going to leaders of countries hostile to us. Then there's accelerating development in China, India and other developing economies that are reliant on fossil fuels.

Rupert Murdoch
  • News Corp. owns Fox.
  • “Climate change poses clear, catastrophic threats” and that “We may not agree on the extent, but we certainly can’t afford the risk of inaction.”
    • Rupert Murdoch, May 9, 2007
  • James Murdoch, heir apparent
    • “Thanks to friendships with Al Gore and Bill Clinton, he has developed deep green instincts,”
      • London Telegraph
    • Wife Kathryn Hufschmid works for Clinton Climate Initiative
who said it
Who said it?

Yes, Glenn Beck

  • Yes, I think the globe has warmed a bit! Approximately 0.74 degree Celsius (+/- 0.18 degree) in the past 100 years.
  • Yes, I think that man might be responsible for some part of that warming, although I’m not 100 percent convinced of how much
  • The cost of generating power from wind has dropped by 60 percent since 1990, and power from the first solar cells in satellites is now 98.7 cheaper than when it was introduced.
  • These technologies will be adopted by the world when - and only when-- they make economic sense, not when we have to depend on countries like Russia and China to be virtuous. Sure, our government can help in the form of tax breaks and incentives, but capitalism is already well on its way to solving this problem itself.
slide31

83% of Americans say world is warming

    • 71% of those think it’s caused partly or mostly by humans
    • 75% said it was warming last year
  • Skeptics more certain they’re right
    • From 35% to 53%
  • 15% of voters say it is their primary concern
a hoax
A Hoax
  • Global warming, as a man-made and highly threatening phenomenon, is at best an exaggeration, at worst an utter “hoax.”
    • Over half of House Republicans
    • Three-quarters of Senate Republicans
  • “Hoax”
    • James Inhofe, ranking Republican on Senate Environment and Public Works Committee
