[H/T to co2sceptics.com] In his debate with Gov. Sarah Palin, Sen. Joseph
Biden stated categorically that he was certain that human activity was
causing global warming. Sen. Biden seems not to be aware that there has been no global warming since before 2002 and that there has never been a time in climate history when carbon dioxide was a significant cause of climate change.
Biden's comments about global warming during his debate with Sarah
Palin indicate he holds a very dangerous view about Earth's climate,
climate change, and global warming.
Biden claims he is absolutely convinced that global warming is real and that it is caused by human activity.
The facts tell a different story:
- IPCC AGW theory calls for a tropical mid-tropospheric "greenhouse signal" ... no such signal exists (The Missing Greenhouse Signal). This is one fatal flaw in the theory to which Biden subscribes.
-
IPCC AGW theory requires surface warming in polar regions before other
lower latitude regions will feel effects of greenhouse warming. Yet
the vast bulk of Antarctica is on a six-decade cooling binge (unabated
by rising atmospheric carbon dioxide) and even recent Arctic warming
has now been attributed primarily to changes in ocean and atmospheric
circulation patterns that have driven warmer water & air toward the
poles (not the mechanism predicted by the IPCC theory). Predictions of
an ice-free Arctic Sea fell far short this year as 9% less ice melt was
observed during summer 2008 than occurred during summer 2007. This is
another fatal flaw in the theory to which Biden subscribes.
-
IPCC AGW theory assumes a feedback from CO2 warming that grossly
overstates the impact of warming from water vapor as a consequence of
theorized warming from additional CO2. (see Climate Sensitivity Reconsidered) Another killer for Biden's accepted theory.
-
IPCC AGW theory states that more atmospheric CO2 will create more
global warming. Yet there has been no global warming since prior to
2002 and the drop in both ocean sea surface temperature and global
average temperature since 2006 has been remarkable, giving up almost
all of what was gained during the 20th Century, all the while CO2 has
continued its nearly 300-year upward trend. (see graph)
The fact that warming began long before significant human CO2
emissions began should have some impact on Biden and other
AGW-believers, but apparently it does not. This has to be a terribly
inconvenient fact for Biden and other AGW-believers.
Elementary
physics informs us that there is just so much atmospheric warming that
can be achieved with CO2 and that the warming capacity decreases
logarithmically as more CO2 is added to the atmosphere. Considering
that CO2 is responsible for less than 5% of heat retained by the
atmosphere and considering that 70% of the potential of CO2 to retain
atmospheric heat has already been achieved, there appears little
likelihood that significant additional heating will be realized by
anticipated increases in atmospheric CO2 in the future. This, coupled
with the evident over-assumption of the feedback of CO2 heating on
water vapor's contribution to additional heating provides little
support to the AGW theory (see A Primer on CO2 and Climate, Dr. Howard
C. Hayden, and Climate Sensitivity Reconsidered).
In
short, the AGW theory is based on assumptions about a science that is
poorly understood and in its relative infancy. It relies upon
inappropriate use of parametric simulations based on assumed feedbacks
that cannot be scientifically verified or validated. And, to top it
all, the theory is rendered invalid by multiple inconsistencies with
observed reality! (no greenhouse warming signal, polar cooling, global
cooling since 2002, ocean cooling, sea level drop due to ocean cooling,
etc.)
Yet Biden, for reasons best known to himself, believes this theory wholeheartedly!
If Biden is so committed to such an obviously flawed theory (where has he been
since 2002 when temperatures began dropping?), does he have the
objective intellectual capacity to deal with less obvious issues?
In a word, no.
