Global Warming - the 20th Century : http://www.mala.bc.ca/~earles/ipcc-tar-feb01.htm Global Warming - the 20th Century
250 yrs of Carbon Emissions : 250 yrs of Carbon Emissions It took 125 years to burn the first trillion barrels of oil – we’ll
burn the next trillion in less than 30 years – why should you care?
Rising CO2 over 50 Years : Rising CO2 over 50 Years http://earthguide.ucsd.edu/globalchange/keeling_curve/01.html
Carbon Emissions and CO2 : Carbon Emissions and CO2 Carbon burned => CO2
Linear from 1850 to 2000
- ppm CO2 =2.55 e10-4 *M tons C + 297 ppm (r2*100=99%)
~ 50% of carbon goes into atmospheric CO2
33% into the oceans
Trend is constant over 150 years – is this how the biosphere will react over the next 150 years? A near perfect correlation that predicts ppm CO2 from total carbon burned

Global Climate Models (GCM) : Global Climate Models (GCM) Ab Initio modeling
From first principles
Modeling land and sea temps from 1900 - 2000
Complexity and data
Climate is a dynamic system – ‘complex’ math
GISS study
10 year study over oceans
Sea temps ~7,500 ft depth
Satellite data for forcing
Slide12 : http://www.grida.no/climate/vital/04.htm
Forcing Calculations : Forcing Calculations Forcing (Watts) = atmospheric forcing factor multiplied by:
ln (ppm gas conc. current / ppm gas conc. historic)
2) ATM forcing factor for CO2 calculated (est.) to be 5.85 watts
3) For 2005, calculation = 5.85 W * ln (380 ppm / 280 ppm) = ~1.8W
4) For CO2, climate sensitivity = 2/3 degree C per 1 watt of forcing
5) 25 to 50 years for the climate to respond to 60% of this forcing Some math is required…. You can model this in Excel and predict temperatures from ppm [CO2]
Earth Out of Balance : Earth Out of Balance http://www.giss.nasa.gov/research/news/20050428/
Forcing, Predicted Temperature, and Climate Lag, 2000 - 2100 : Forcing, Predicted Temperature, and Climate Lag, 2000 - 2100 0F - Model built assuming ~60% of forcing is felt in ~25 years
The Carbon Cycle : The Carbon Cycle Why atmospheric CO2 is the last thing on earth humans should have interfered with!
We are releasing CO2 at one million times the rate that earth initially sequestered it at
We inserted ourselves in the carbon cycle
And are affecting the ‘thermostat of life’
Earth uses CO2 to help maintain an optimum temperature for the biosphere, for > 650K years
The Thermostat of Life : The Thermostat of Life Vostok ice core data show regular and repeating cycles of temps and CO2 over last ~500,000 years
Oscillate between 180 and 280 ppm CO2 and 100 C
Hypothesis that earth regulates the temperature of the planet through CO2 / greenhouse effect
Biosphere maintains a precise level of CO2 for life
But the biosphere isn’t really absorbing our CO2
Y intercept of cum. carbon burn / CO2 is 297 ppm
http://courses.washington.edu/pcc589/papers/Shackleton2000.pdf
Vostok CO2 and Temperature : Vostok CO2 and Temperature The relationship between CO2 and temperature is nearly perfect (r2*100 = 99)
However, the casual relationship is the basis for significant (expert) controversy
Why does this occur?
The Vostok Equilibrium : The Vostok Equilibrium Vostok ‘equilibrium’
100K year cycles
earth’s orbital eccentricity
Sun heats up the planet
Biosphere expands
CO2 maintains temp
Otherwise earth would be very cold ~ 0 degrees F
CO2 has not exceeded 280 ppm in the last 500K years and 4 major cycles
Crux of the Vostok Data : Crux of the Vostok Data Temperature leads biomass CO2, then CO2 maintains temperature
Just One Degree F : Just One Degree F These examples will show the affect of warming the earth at just one degree F
And for less than 50 years!
Warming has accelerated in last ~20 years
The affect of temperature is cumulative
Earth takes decades to centuries to react
And we still owe an additional degree F!
Long Term Warming Effects : Long Term Warming Effects Not just increased temperature, but added heat, for a long, long, time!
Consequences of Warming : Consequences of Warming Thinning of polar ice caps
Thawing permafrost / release of methane
Slowing of the thermohaline cycle
Rising sea level, perhaps quickly
Extreme weather events
Extended regions of drought
Extremes of temperature / duration
Extremes of storms and hurricanes All these are consequences of only one degree F for <50 years!
Storms on the Move : Storms on the Move Katrina moving
across Florida
in late August 2005

in the Gulf of Mexico And grows from a
category 1 to a
category 5 hurricane
in less than 2 days!
The Melting North Pole : The Melting North Pole The North Pole is thinning in area ~10% per decade,
and thinning in thickness ~1 meter per decade. At these
rates, it may be an open sea as early as 2030 – 2050. http://earthobservatory.nasa.gov/Study/ClimateClues/

Thermohaline Cycle : Thermohaline Cycle NASA schematic view of ocean circulation. The light colored path shows the general movement of the surface waters and the dark colored path shows the movement of water at depth. The numbers show the position of: 1. The Gulf Stream which transports heat from the tropics to northern Europe. 2. North Atlantic Deep Water formation which results from strong cooling. 3. Antarctic Bottom Water formation due to sea ice production around Antarctica.

of earth’s fresh water Like the Arctic, it
moderates the climate

Thermal expansion is 1 – 2 cm / 10 yrs.
But is accelerating to 2.5 cm / decade
For every 1 0C, sea expands ~1 meter in height - sea cannot expand ‘down or out’ http://yosemite.epa.gov/oar/globalwarming.nsf/content/ResourceCenterPublicationsProbability.html
