    Defense Against Climate-Deniers

    Climate change can be a touchy subject as it is often the center of many heated partisan

    debates that range from the halls of Congress to the water coolers of offices across the nation.

    For years, science and reason have often fallen along the wayside in favor of ad hominem attacks

    and a prolonged stance of ignorance and simple disinterest by the American public. Climate

    deniers often confound pure statistical data in order to confuse the general public to adopt a

    stance of apathy which often leads to uneducated and ultimately ineffective responses to global

    warming. Given the dire consequences global warming can have on all people across the globe,

    the lethargy that plagues current environmental policy must be countered by a fundamental

    change in the way the federal government and the general public understands climate change.

    Despite several interesting claims by climate-deniers it is clear global warming presents a real

    and omnipresent threat to human existence. With the knowledge that global warming is real, it is

    imperative that the federal government substantially increase funding for pro-climate change

    policies

    The first and foremost issue that currently confronts pro-climate change policies is an a

    better understanding of climate change is an ignorant and subsequently misinformed public. As

    John Cook, who possesses a Ph.D. in Chemistry at Michigan Tech put it, there is a significant

    gap between public perception and reality that often stems from campaigns designed to

    Nelson 2

    confuse the public about the level of agreement among climate scientists (Cook). As Cook put

    it, The narrative presented by some dissenters is that the scientific consensus is '...on the po int

    of collapse' (Cook). These campaigns are often very well-funded (often by large, fossil-fuel

    based companies) and tend to be published in very public manners (Cook). In August of 2012,

    the Wall Street Journal published an article by several climate scientists that attempted to

    disprove the correlation between human activities and perceived increases in global temperatures

    (Nuccitelli). Initially, this report could have been dangerous to the growing tide of the American

    public who in recent years began to change positions on the veracity of global warming claims

    (Nucitelli). However, a brief review of these so called climate scientists and their credentials

    seems to disprove their conclusions. According to Dana Nuccitelli, a climate scientists at a

    private firm in Sacramento, these climate-deniers echo the warnings of Cook as Roger Cohen,

    William Happer, and Richard Lindzenwere signatories on that letter and that neither Happer

    nor Cohen has a single climate science publication to his name, while Happer is a member of two

    fossil fuel-funded climate denialist think tanksand Cohen has previously worked for

    ExxonMobil. These statements provide a very frightening example of how biased or even

    unqualified climate deniers often are. However, despite some biases their arguments should still

    be viewed as a scientific inquiry and should be treated as such. However, the problem occurs

    when the scientific community seeks to verify the research and statistics these scientists use as

    they continue to publish their opinions in the conservative mainstream media rather than

    subjecting their arguments to the scientific peer-review process (Nuccitelli). Simply put, these

    claims cannot be verified because the methods climate deniers use to verify their claims are not

    subject to peer-review by the scientific community (Nuccitelli). Conversely, the peer-reviewed

    scientific consensus is that global warming is both real and human induced. The assertion, like

  • 8/11/2019 A Defense of Climate Deniers

    3/8

    Nelson 3

    the one made in the wall street journal, that a majority of climate scientists disagree with

    anthropogenic climate change is disproven by a review of the past 20 years of climate papers

    published in the United States. According to Cook, A systematic, comprehensive review of the

    literature provides quantitative evidence countering this assertion. The number of papers

    rejecting AGW (anthropogenic global warming) is a miniscule proportion of the published

    research (Cook). In fact, the percentage of climate papers published that provide support for

    anthropogenic global warming is astonishing. Among papers expressing a position on AGW, an

    overwhelming percentage (97.2%) endorses the scientific consensus on AGW (Cook). From

    this data it is clear that a majority of scientists support the notion that the earths temperatures are

    increasing due to human activities.

    However, there are some other, extremely specific (often statistically backed) arguments

    climate-deniers use to justify their positions. One interesting argument proposed by climate

    deniers is that the earth has recently entered a period of cooling. According to Alan Carlin who

    has a Ph.D. in Economics from MIT and was previously the Director of the EPA, Earth is

    currently in an interglacial period quite similar to others before and after each of the glacial

    periods that Earth has experienced over the last 3 million years and that there does not appear

    to be instability towards much warmer temperatures during interglacial periods. There is rather

    instability towards much colder temperatures (Carlin). The argument that the earth is

    statistically cooling currently may hold some scientific truth. Laurence Hecht, the editor of 21st

    Century Science and Technology journal attributed this global cooling Carlin observed to the

    fact that solar activity is declining; the current solar cycle is likely to be a weak one. The

    following cycle, beginning around 2018 to 2020, may be so weak as to bring on a extremely

    cold climate, like that in the period known as the Little Ice Age (Hecht). This is a potentially

  • 8/11/2019 A Defense of Climate Deniers

    4/8

    Nelson 4

    frightening scenario to many, as crop failure and disease was rampant during the little ice age

    (Hecht). However, these are assumptions based on past data and do not assume the future impact

    of large CO2 emissions. In fact, Richard Somerville who is a distinguished Professor Emeritus of

    Oceanography at the University of California-San Diego even concedes that solar variability can

    impact current climate models. In his 2011 testimony to the United States House Committee on

    Energy and Commerce he said natural events canlead to slight temporary cooling. Solar

    output was also at its lowest level of the satellite era and subsequently the global average near-

    surface atmospheric temperature in 2008 was only about 0.1 deg C less than in the years

    immediately preceding it (United States House Committee on Energy and Commerce).

    However, it would be imprudent to base future climate models on this information because

    Such a small difference over such a short time is not statistically significant in evaluating

    trends (United States House Committee on Energy). Somerville completed his testimony in

    congress by concluding the most recent ten-year period is still warmer than the previous ten-

    year period. The long-term trend is clearly still a warming trend. So while the notion that the

    earth is cooling due to solar variability is an accurate statement, it can be quite misleading

    because even after accounting for a decrease in solar activity, the earth is continuing to warm.

    However, there are several observable ways to prove climate change is an ever-threatening

    problem.

    Separate from predictive climate models, the evidence of global warming can be seen and

    measured in plenty of distinct places, but none more noticeable than the polar ice caps.

    According to Andrew Freedman, an author for the Climate Science Journal, Arctic sea ice cover

    is likely to reach a new record low in the coming months and that it is one of the most visible

    signs of manmade global warming (Freedman). Even while the overall temperature of the earth

    Nelson 5

    decreases, the rate at which the arctic has decreased has nearly doubled since the 1980s

    (Freedman). With all of this in mind it is clear that a change in environmental policy is crucial to

    maintaining a stable environment. Thus, physical changes observable in the environment in

    conjunction with future climate models that account for decreases in solar variability prove with

    near certainty that global warming is continuing to rapidly increase and alter the environment.

    Alone this evidence seems very convincing however scientific studies have confirmed other

    physical changes that point to global warming.

    One physical change that the earth has recently undergone is a measurable increase in

    ocean temperature. In fact, a report published by The World Bank prepared by the Potsdam

    Institute for Climate Impact Research and Climate Analytics said The observed warming of the

    worlds oceans can only be explained by the increase in atmospheric greenhouse gases.(Turn

    Down The Heat). Scott Johnson, who possesses a Masters in Hydrogeology from the University

    of Wisconson-Madison said in early 2012 reliable records of ocean temperatures found that the

    anthropogenic fingerprint was apparent in the observed temperature record at the 99 percent

    confidence level(Johnson). These results can be particularly convincing however as Spencer

    Roy, a former NASA scientist pointed out Early measurements of ocean temperatures were

    taken from buckets dipped in the ocean from the decks of ships while later, temperatures would

    be taken well below a ships water line, in the intake ports for water that cooled the ship's engine

    (Roy). This is a valid criticism but even Roy concedes that estimates of ocean warming over the

    last hundred years are, at best, uncertain (Roy). Thus it is clear that non-biased physical changes

    clearly show that the earth is statistically warming.

    While global warming often incites heated partisan debates, scientific consensus is clear

    global warming is both real and anthropogenic, and the disadvantages of continuing a lethargic

    environmental policy are simply too great to continue to allow climate-deniers to propagate the

    myth that global warming is neither real or a threat to human existence.
