Climate-gate
Global Warming The worldwide rise in average surface temperatures
Thought to be caused by the Greenhouse Effect
The Greenhouse Effect
The ability of gases in the atmosphere to slow
down the release of heat into space at night
Greenhouse Gases
The Greenhouse Effect It is essential to life!
Other wise it would be 225°F in the day & -243°F at night.
The Greenhouse EffectThe burning of fossil fuels increases the concentration of carbon dioxide in the atmosphere
Other variables
The Father of Global Warming
Columbia University geochemist Wally Broecker is thought to be the father of Global Warming

Inconvenient Truth” Former Vice President of
the United States Two time Presidential
Candidate (1988 and
2000) Nobel Peace Prize Winner Took the initiative in

Al Gore on Global Warming
Global warming, along with the cutting and
burning of forests and other critical habitats,
is causing the loss of living species at a level
comparable to the extinction event that wiped
out the dinosaurs 65 million years ago. That
event was believed to have been caused by a
giant asteroid. This time it is not an asteroid
colliding with the Earth and wreaking havoc:
it is us." — Al Gore

Carbon Dioxide
Allows sunlight and heat into theatmosphere, but doesn't let it getout, causing the Earth to heat up.
So what about the other gases?
Methane
That remains in the atmosphere for approximately 9-15 years.
Methane is over 20 times more effective in trapping heat in the atmosphere than carbon dioxide (CO2) over a 100-year period.
Emitted from a variety of natural and human-influenced sources.
With the planetary effects of long-term human
negligence exposing itself more and more
everyday, experts are now experimenting with
cow farts and burps in an attempt to curb
global warming.
Cows – get them before they get you!
Certain environmentalists want to tax farmers and ranchers for the total number of cattle they own to offset their Methane output.
It’s not animal cruelty if you are
saving the planet.
Nitrous Oxide
Nitrous Oxide (N20) is clear, colorless gas
Lifetime of N2O is 120 years
It’s heat trapping is 310% more than CO2
Removed by photolysis
N2O has natural and human-related sources
Some Sources include:
▪ Agricultural soil management
▪ Mobile and stationary combustion of fossil fuel
▪ Adipic acid & nitric acid production
▪ Biologically
▪ 60% of N20 is natural
ANTAGONISTANTAGONISTSS
Current Views
The global temperature has risen 0.6° ± 0.2 °C.
More evidence shows increase in CO2 and Methane.
If we continue the temperatures will increase 1.4°C to 5.8°C in the next 100 years and include more extreme weather.
Antagonistic Views
1.IPCC Data is inaccurate
2.Warming is natural
3.Cause of warming unknown
4.Warming has few negative effects
IPCC data is inaccurateUnethical Graph
CRU’s data base was hacked in late 2009.
Included over 160 MB of emails, documents, and research.
Lacked research to create an accurate report.

Responses
Email - “The fact is that we can’t account for the lack of warming at the moment and it is a travesty that we can’t.”(Revkin, A C.)
IPCC 2007 - ”Is one that holds under a variety of approaches, methods, models and assumptions, and is expected to be relatively unaffected by uncertainties.”(Henig, J.)
NY Times - ”They seem so focused on winning the public-relations war that they exaggerate their certitude — and ultimately undermine their own cause.”(Tierney, J.)
Warming is natural

“Portrayed that there
isn’t a major
catastrophe or death
knell hanging before the
world, but rather a
comparison of loosely
based ideas of climate
models and the changes
in CO2 levels which are
uncertain hypothesis.”
John Christy -- Professor of atmospheric science and director of the Earth System Science Center at the University of Alabama in Huntsville
26Beneficial
“If there is global
warming caused by the
increase of CO2 level
that it would be a good
thing because it would
allow food, timber, and
temperatures to provide
a greater quality of life.
Warming has been
shown to positively
impact human health.”Craig Idso -- Faculty researcher, Office of Climatology, Arizona State University and founder of the Center for the Study of Carbon Dioxide and Global Change
Conclusion
Pew Research Poll
Overall we can see that if you take a
careful look at some of the factors you can
rule out that man has had a nil effect
when contributing to warming trend. One
scientist stated that there has been a
0.12% increase in CO2 levels and then
states,“ It’s miniscule It’s nothing.”(Dialog,
T.)
