During
this week, we read series of online articles, grey literature, and a peer
reviewed journal article published in Nature Climate about the understanding of
climate change among skeptics and or denials. The Ruckelshaus et al (2013)
presents the Republican’s case that Earth’s climate is changing at an
unprecedented rate. They argued that the debate of climate change is not a
matter of partisanship, but a matter of taking precautionary actions that are
cost-effective and that has the potential to significantly reduce anthropogenic
greenhouse gas emissions. Ruckelshaus et
al (2013) added that the same momentum that led the United States and other nations
to act in mitigating the depleting ozone, which brought about global outcry
against CFCs should be the same guiding steps based on “common-sense
conservative principles” in protecting the general welfare of the American
populace, the environment, climate systems, and the world at large. They
suggested that the market-based approach or what some may term as cost benefit
analysis regulatory framework of climate change mitigation over the years has
proven to be effective and doable and has significantly improve our economy as
well.
Lindzen’s
article “Climate science isn’t settled: confident predictions of catastrophe
are unwarranted” takes a different direction from what Ruckelshaus et al.
(2013) suggested that the reality of climate change is undeniable. Lindzen
argues that globally over the last few dozen years, global average temperature
anomaly (GATA) fluctuates. He argues the assertions that “climate change is
accelerating are bizzare” (Landzen, 2009). He also added that the emergence
from the period of the little ice age, which occurred between the 15th
and 19th centuries and the commencement of the industrial
revolution, which explains why global temperature increases as we migrate from
a period of cold climate to warmer climate. He noted that in the midst of
global climate change, which is a result of the release of greenhouse gases
into the atmosphere, CO2 is generally accepted as the prominent greenhouse gas
emitted. He presented the case that Earth’s atmospheric systems “balance the
incoming solar radiation by subsequently releasing thermal radiation, and the
presence of high clouds and water vapor, which are “greenhouse substances”
deters the system from cooling, which leads to “some” warming. He concludes
that these factors (water vapor and high clouds) are major greenhouse
substances, which can be differentiated from “minor” anthropogenic substances, which he states are anthropogenic greenhouse gases.
He asserts, “doubling of CO2 would only offset the original balance within the
system between incoming solar radiation and outgoing radiation to about 2%”
(Lindzen, 2009), which is what is considered within the scientific literature
as “climate forcing,” which is a natural process. He argues that the failure
amongst climate change scientists to establish the linkages between observed
warming and observed warming in minor anthropogenic warming makes the climate
change vis-a-vis global warming discourse weak and unwarranted and there is no
need for public outcry. He concludes by suggesting that natural disasters that
are linked to climate variability are all confluence of multiples factors that
we tend to link to our carbon footprint.
Holdren’s
article on “convincing the climate-change skeptics” highlights the three
categorical approaches of climate change skeptics that tend to be factually
untrue and supported with no evidence that earth’s climate is warming, but
humans are not main cause of such warming (Holdren, 2008). He noted that national and
international consensus that earth’s climate is rapidly change should set the
score for the public to make objective decisions when they encounter climate
change skeptics. He asserts that most climate change skeptics are Republicans a
claim that I do not support and partially been reactionary than
addressing the fact that climate change really matters.
Changes in the
world and the way the world thinks is information and knowledge. This has not
proven to be true in the case of science and the issue of climate change as Roberts
notes in his article “More Science Will Not Cure the Climate Skepticism.”
Roberts also mentions three things that could have been barriers to the lack of
understanding of the dangers that climate poses to society: the people around
us i.e. culture, education and the media, but Kahan et al. 2012 mentions that
this it goes beyond that. The issue of people affecting believes and the
article of Adam Frank in the New York Times nicely outlined perspectives. It
gives statistics about creationist during his college ages. Probably the
increased is due to knowledge or the kind of cultural training that younger generation
have received from the older generations, meanwhile the issue of climate change
has not seen anything to correlate to such belief. The factual problem of
climate change has not gotten that much of attention like it was intended to.
The issue has become highly politicized and people’s affiliation to a political
party or a political figure also affects how he will view climate change. David
wrote in his paper what is happening in North Carolina where state planners
have been banned from using climate data in projecting future sea level rise.
Politicians have risen to the point of explaining scientific issues with
politic which Michael Man calls “scientization of politics.”
On the subject of
education, it is evident that more education does not necessarily mean that
people will take the subject of climate change serious. The ordinary person is
said to belong to the SCT (Science Comprehension Thesis) group that is people
with very little knowledge of science. If this is true then with the increase
of the number of colleges and private institution all around us should make the
subject of climate change more meaningful and taken very serious. The
alternative group, CCT, (Cultural Cognitive Thesis) is a person that due to
complex psychological mechanisms sees risk based on things that the group he
belongs to sees it as such. So while “SCT emphasizes a conflict between
scientist and the public, CCT stresses one between different segments of the
public, whose members are motivated to fit their interpretations of scientific
evidence to their competing cultural philosophies” (Kahan et al 2012, page
732). The challenge of this world as far as climate change is concern is a
complex one, and involves not just the understanding of scientific processes,
but also the way the scientific information is disseminated.
