Some Questions
  • Have you heard about climate change and its
    possible consequences?
  • Do you think there is debate in the relevant
    peer-reviewed scientific literature (atmospheric
    science and meteorology) among scientists
    regarding the existence if climate change and its
    causes?
  • or in the media / blogs / web sites / or among
    politicians.

6
In solving problems which should carry the most
weight?
Evidence, Facts, Discernible Reality, Reason,
Rational analysis of the world as it exists
Illusions, Distortions, Deceptions, Half Truths,
Claims about the world as it might be or as
wed like it to be.
7
Some Erroneous Debates
  • Tobacco and Health Effects.
  • Tobacco Company campaign to manufacture doubt.
  • Chlorofluorocarbons (CFCs) and the atmospheric
    ozone hole.
  • The silly season of Presidential politics -
  • Is Barrack Obama a Christian or a Muslim?
  • Is John McCain a conventional Republican or a
    maverick?
  • Dont just accept what you hear especially from
    the media check reliable credible sources for
    yourself.
  • Ignore political commentators and web sites /
    blogs with dogmatic pre-determined axes to grind.

First .
  • A few words about what is happening
  • The recent global climate pattern and
  • Whats causing it

What does the PrecautionaryPrinciple urge?
There is much doubt depends on what we do.
We know the disease were just not sure about
the exact prognosis
Like a Cancer Diagnosis We know you are sick
But the prognosis dependson what you do.

19
Response to Catastrophe
  • Kübler-Ross Five Stages
  • Denial
  • Aint a river in Egypt.
  • We cannot possibly influence climate!
  • Anger.
  • We gotta find someone else to blame.
  • Bargaining.
  • Surely somebody can do something about this!
  • Despair.
  • Aint the extra tire in your trunk.
  • Its too big a problem theres nothing we can
    do
  • Acceptance
  • Its time to figure out what we can do.
  • Only when we reach Acceptance can we do anything.

20
Who Are the Experts?
  • 1) IPCC Intergovernmental Panel on Climate
    Change WMU UNEP, 1988
  • WG I The Physical Science gt 600 Relevant
    ScientistsPlus gt 450 Reviewers.
  • WGII Impacts, Adaptation Vulnerability gt300
    ExpertsPlus gt 750 reviewers
  • WG III Mitigation of Climate Change gt 250
    ExpertsPlus gt 400 Reviewers

What Did They Conclude (2007)?
  • Global Warming is happening.
  • There is a 90 probability that human activity -
    increasing greenhouse gases - is the cause.

21
Who Are the Skeptics?
  • Mainly non-scientists or scientists with no
    relevant expertise.
  • Staff of institutes and think tanks funded to a
    significant extent by oil corporations.
  • e.g. between 1998 2008 Exxon/Mobil has run a
    disinformation campaign manufacturing doubt in
    the publics mind while contributing 23 million
    to the skeptic organizations.
  • Individuals committed to a political philosophy
    that rejects on principle regulations to address
    environmental problems.
  • A small number of contrarian scientists with
    relevant expertise publishing in vanity press,
    non-peer reviewed journals, or journals in
    unrelated fields without editors knowledgeable
    enough to peer-review legitimately.
  • Overall a small number of individuals (app. 15)
    are driving the skeptic movement.

22
Sampling The Skeptics
  • Cannot possibly address all the weird and
    esoteric criticisms launched by the skeptics of
    climate change theoryfocus on 3.
  • There is no scientific consensus.
  • There is no climate change i.e. global warming is
    a myth.
  • Climate is changing, but its a natural cycle.

23
1-There is no scientific consensus.
  • Important to appreciate how scientific consensus
    is reached
  • It is a legitimate scientific occurrence.
  • Through publication in peer-reviewed primary
    scientific journals.
  • Through discussions and exchange of information
    and ideas at relevant conferences.
  • Through evaluations of research and reports by
    National Academies.

24
Is There scientific dispute with IPCC conclusions?
  • Oreskes (Science 2004) reported on a sample of
    928 relevant papers in the peer-reviewed
    literature
  • not one challenged the consensus view.
  • Science Editor Donald Kennedy pointed out
    skeptic manuscripts were simply not being
    submitted.
  • The National Academy of Science evaluated the
    2004 IPCC Third Assessment Report (TAR) and
    confirmed its conclusions.

There is not one major professional organization
that rejects the IPCC consensus
26
Conclusion
Meanwhile according to the Mainstream Media
there is still scientific debate
  • In reality, to claim there is no scientific
    consensus that serious scientific debate
    remains is simply absurd.

27
2-There is no global warming.
Michael Crichtons U.S. Temperature Graph
1) Michael Crichtons State of Fear was
published in 2004, so the data used could have
been more recent than the last century.
2) But Crichton stopped the 5 year running mean
the darker line in 1995.
3) So, lets extend the lines to include more
current data.
When does the line terminate?

American Physical Society
  • The following article has not undergone any
    scientific peer review, since that is not normal
    procedure for American Physical Society
    newsletters. The American Physical Society
    reaffirms the following position on climate
    change, adopted by its governing body, the APS
    Council, on November 18, 2007 "Emissions of
    greenhouse gases from human activities are
    changing the atmosphere in ways that affect the
    Earth's climate."

37
Is the Hadley Center suggesting cooling?

38
And what does the University of Alabama
(Huntsville) conclude?
June 2008 Newswise Global trend since Nov. 16,
1978 0.13 C per decade A La Niña Pacific
Ocean cooling event continues to drive tropical
and global temperatures Globally, June 2008 was
the coolest June since 1999.
39
Conclusion
Even if we cannot prove the planet is warming
the data are quite compelling

Milankovitch Cycle
  • A 100,000 year temperature cycle results from 3
    component cycles
  • I 105,000 yr. cycle in shape of Earths orbit
    of sun- Eccentricity

45
Milankovitch Cycle
  • A 100,000 year temperature cycle results from 3
    component cycles
  • II 41,000 yr. cycle in the tilt (obliquity of
    ecliptic) of Earth 21.1o-24.5o around 23.5o.

46
Milankovitch Cycle
  • A 100,000 year temperature cycle results from 3
    component cycles
  • III 21,000 cyclic advance of the equinoxes
    date when sun is over equator. Jan ? Feb ?
    March..? ? January.

47
Milankovitch Cycle
  • Consequence
  • No change in total solar radiation but
  • A cycle in severity of seasons
  • From warm summers/cold winters to cool
    summers/mild winters
  • Glaciation occurs when summer is not warm enough
    to melt winter snows.

http//www.globalchange.umich.edu/globalchange1/cu
rrent/lectures/samson/climate_patterns/
48
Coincidence in the three cycles
  • When all the Milankovitch cycles (alone) are
    taken into account, the present trend should be
    towards a cooler climate in the Northern
    Hemisphere, with extending glaciation.

49
Isnt it all Solar Activity?

The Friis-Christensen and Lassen (1991) data
are used suggest so (The image shown in a 2007

But wasnt there a consensus of global cooling 30
- 40 years ago?
Study by Peterson (NOAA Climate Data Center,
Connelly National Environmental Research Center,
U.K. and Fleck .
http//ams.confex.com/ams/pdfpapers/131047.pdf
52
Not only were there few papers, but also few
citations to them
The count on these papers was extended through
1983 Cooling 325 (12), Neutral 424 (15½) ,
Warming 1958 (72).
Additionally no consensus in the media
http//ams.confex.com/ams/pdfpapers/131047.pdf
53
Conclusion
We know there are natural fluctuations but the
current pattern of warming seems to deny that
any of the natural causes are significantly in
play.
54
Summary
Global warming is always ahead of us. In addition
to the one degree weve already warmed, by our
actions to date another degree has already been
built into the climate.
The Skeptics are cherry-picking selected (usually
old and outdated) data, deceiving and distorting,
and some are not beyond lying.
Remind you of anything?
In an analogous fashion to those who still think
Iraq was involved in 9-11, had Weapons of Mass
Destruction, and posed a nuclear threat to the
United Satesdespite conclusive evidence to the
contrary, there are still Americans who cling to
the illusion that climate change is not
happening, and reject the profoundly convincing
evidence that humans are responsible.
This should NOT be a political question. In
developed nations around the globe, political
parties from right to left have acknowledged the
scientific consensus and have committed to
action. Unfortunately, there are some folks in
the U.S. who identify as a litmus test for being
a genuine Republican, rejection of the evidence
regarding climate change. Denial does not move
us forward especially when represented in the
government.
55
It is time for action
  • James Hansen heads the NASA Goddard Institute for
    Space Studies in New York and serves as adjunct
    professor in the Department of Earth and
    Environmental Sciences at Columbia University
  • Its five past midnight and Time for the Big
    Fix.
  • We must take positive steps to address the
    problem four more years of the same cavalier
    inaction we have seen for the last 8 is not good
    enough.
