Scientists from the University and the Centre for Geodynamics in Norway
have made the first comprehensive model of the Earth's sea level rising
and falling over the last 140 million years, resolving a long-standing
controversy over sea level fluctuations through geological history.
The group, led by Associate Professor Dietmar Müller from the School of
Geosciences at the University of Sydney, has reconstructed the volumes
of ancient ocean basins from the Cretaceous period until the present,
in an article published in the journal Science on the 7 March 2008.
"A global sea level rise of a metre, driven by slowly melting ice
sheets, would have disastrous effects on at least 60 million people in
coastal areas worldwide. But even larger sea level fluctuations have
occurred in the ancient past, in 'hothouse' climates, when neither
humans nor inland ice caps existed," explains Associate Professor
Müller.
"Our goal was to understand these changes, as sea level fluctuations
have been a driving force in the evolution of animals and plants, in
climate change and biogeography," says Associate Professor Müller.
"By creating a detailed set of digital maps of ancient ocean basins we
were able to show that cycles of mid-ocean ridge creation, evolution
and destruction have profoundly effected shifting coastlines and inland
seas through time."

New derivation of equations governing the greenhouse effect reveals "runaway warming" impossible
Miklós
Zágoni isn't just a physicist and environmental researcher. He is
also a global warming activist and Hungary's most outspoken supporter
of the Kyoto Protocol. Or was.
That was until he learned the details of a new theory of the
greenhouse effect, one that not only gave far more accurate climate
predictions here on Earth, but Mars too. The theory was developed by
another Hungarian scientist, Ferenc Miskolczi, an atmospheric physicist
with 30 years of experience and a former researcher with NASA's Ames
Research Center.
After studying it, Zágoni stopped calling global warming a crisis,
and has instead focused on presenting the new theory to other
climatologists. The data fit extremely well. "I fell in love," he stated at the International Climate Change Conference this week.

Some scientists are so convinced that man-made global warming is now
unstoppable and harmful that they are proposing to artificially tamper
with the atmosphere to "fix it". If we truly are heading in to a period
of low solar activity (cooling), as NASA and many others have
predicted, this god like action to slow "global warming" could kill
millions from cold and starvation.
We try to avoid fear
mongering here and base our arguments on science. Historically science
has generally been used to counter ignorance and prejudice, today
science is often used to justify political correctness, to gain social
acceptance or as a means to gaining power and wealth. When used
incorrectly science can cause ignorance and prejudice. When science
losses its built in skepticism it can be nearly impossible for the
average person to know what to trust. We can find no better reason to
fear the current politically tainted scientific community then the
current push towards "geoengineering" to "fix" our climate.
As
has been reported here in previous articles there have been several
studies that say even if we cut CO2 emissions to zero the planet will
continue to warm. The latest study claims we'll continue to warm for
the next 500 years. No one believes we can cut our CO2 emissions to
zero anytime soon and with reports like this one "China's 2030 CO2 Emissions Could Equal the Entire World's Today"
it would hardly be worth other developed countries even trying. Not
that we believe any of the malarkey about a planet doomed by CO2 but
there are many on the left and some vocal scientists that do. This
unfounded fear and the media's mass-hysteria is very dangerous. Cooling
the planet at a time that we're heading in to a Dalton or Maunder Minimum level of solar activity could be disastrous!

With a lack of traditional science, partisans on both sides, and
enormous consequences depending on popular opinion and political will,
it is important that people understand the evidence in the debate over
global warming. Unfortunately, most people do not have the time,
desire, or ability to undertake an independent study of the issues.
Recognizing this, advocates have “packaged” their evidence with charts,
graphs, and other visual exhibits designed to have maximum impact with
minimal effort on the part of the public. These displays, while
appearing to present hard facts, are often misleading.
Environmental activists may be tempted to exaggerate their case in
order to convince the public and politicians of the validity of their
scenarios. This was illustrated in a statement made by climatologist
Stephen H. Schneider, one-time adviser to Vice President Al Gore and
author of the book Global Warming: Are We entering the Greenhouse Century?
(1989). Schneider said that in order to reduce the risk of potentially
disastrous climatic change, “we have to get some broad-based support,
to capture the public’s imagination. That, of course, entails getting
loads of media coverage. So we have to offer up scary scenarios, make
simplified dramatic statements, and make little mention of any doubts
we might have.”

A new study on the use of visual exhibits in the global warming
debate--a tactic employed regularly by former Vice President Al Gore in
his film, An Inconvenient Truth--reveals how graphs, charts, and other images can be accurate and still skew data to support a partisan view.
“Understanding Visual Exhibits in the Global Warming Debate” notes
graphics are an integral component of the national discussion on
climate change. They convey vast amounts of complex information in a
way that is easily understood ... and easily manipulated.
Author Ronald J. Rychlak notes, “Advocates have ‘packaged’ their
evidence with charts, graphs, and other visual exhibits designed to
have maximum impact with minimal effort on the part of the public. The
manipulation of visuals--bar and line graphs, pie charts, even
photographs--has proven to be a highly effective way to offer up scary
scenarios ... and it is easily done.

Abstract:
The public’s fear of anthropogenic
global warming
seems to be at a fever pitch. Polls show most people in most countries
believe human greenhouse gas emissions are a major cause of climate
change and that action must be taken to reduce them, although most
people apparently are not willing to make the financial sacrifices
required.
While the report of the Nongovernmental International Panel on
Climate Change (NIPCC) makes it clear that the scientific debate is
tilting away from global warming alarmism, we are pleased to see the
political debate also is not over. Global warming ‘skeptics’ in the
policy arena include Vaclav Klaus, president of the Czech Republic;
Helmut Schmidt, former German chancellor; and Lord Nigel Lawson, former
United Kingdom chancellor of the exchequer. On the other side are
global warming fearmongers, including UK science advisor Sir David King
and his predecessor Robert May (now Lord May), and of course Al Gore,
former vice president of the U.S. In spite of increasing pressures to
join Kyoto and adopt emission limits on carbon dioxide, President
George W. Bush in the United
States has resisted – so far.
We regret that many advocates in the debate
have chosen to give up debating the science and
now focus almost exclusively on questioning the
motives of ‘skeptics,’ name-calling, and ad
hominem attacks. We view this as a sign of
desperation on their part, and a sign that the debate has shifted toward climate realism.
We hope this study will help bring reason and balance back into the
debate over climate change, and by doing so perhaps save the
peoples of the world from the burden of paying for wasteful,
unnecessary energy and environmental policies. We stand ready to defend
the analysis and conclusion in the study that follows, and to give
further advice to policymakers who are openminded on this most
important topic.
