Right-wing media are laughing about President Barack Obama mentioning climate change in his fifth State of the Union address because it is cold in D.C. But the wobbly polar vortex bringing cold air to much of the contiguous United States is simultaneously causing record warmth in Alaska, a state often seen as the nation's "ground zero" for climate change.
On January 28, Alaska's largest newspaper, the Anchorage Daily News, ran this remarkable headline: "Record warmth, confused plants: An Alaska January to remember." The article noted that it was 62 degrees Fahrenheit in one town, tying the January state record, but did not allude to the long-term warming trend. In November, the newspaper did briefly invoke the possibility of climate change while expressing disbelief that strawberries were growing "In Anchorage. In November."
Yet just a year ago, right-wing media claimed the state was headed toward "an ice age." The Alaska Dispatch, a prominent online news site, ran the misleading headline, "Forget global warming, Alaska is headed for an ice age." The report was promoted by the conservative British tabloid, the Daily Mail, and the climate denial site, WattsUpWithThat, which highlighted the state's relatively lower average temperature in 2012.
As the chart above also shows though, cherry-picking a short-time period is misleading -- natural variation can mask the long-term trend. Contrary to claims of an "ice age," studies project that average annual temperatures in Alaska will increase "an additional 3.5 to 7°F by the middle of this century," according to the Environmental Protection Agency (EPA).
Warming in Alaska already has caused highways to buckle and homes in areas such as Shismaref, pictured above, to sink, as the EPA explained:
Many of Alaska's highways are built on permafrost. When permafrost thaws, roads buckle. Vehicles are only allowed to drive across certain roads in the tundra when the ground is frozen solid. In the past 30 years, the number of days when travel is allowed on the tundra has decreased from 200 days to 100 days per year.
Along Alaska's northwestern coast, increased coastal erosion is causing some shorelines to retreat at rates averaging tens of feet per year. Here, melting sea ice has reduced natural coastal protection. In Shishmaref, Kivalina, and other Alaska Native Villages, erosion has caused homes to collapse into the sea. Severe erosion has forced some Alaska Native Villages' populations to relocate in order to protect lives and property.

The Washington Times is claiming that carbon emissions could be causing "global cooling" in contradiction of basic physics.
In an editorial Monday designed to ridicule Sen. Harry Reid (D-NV) for convening a summit on clean energy in Las Vegas, the Times repeatedly referred to climate change as a "scam" and cited several "facts" that allegedly discredit it -- including that "there's new evidence that carbon-dioxide emissions, which first set off global-warming hysteria, are actually triggering global cooling."
But there isn't "new evidence" of that. Or any kind of evidence, really.
As Duke University scientist William Chameides explained to Media Matters when Fox News tried to advance this "utter nonsense" claim, scientists established the greenhouse effect "more than a century ago":
What CO2 does is trap a larger amount of the heat from the sun, preventing it from escaping and thus driving up temperatures. To argue otherwise is to argue that the greenhouse effect does not exist. In fact the existence of the greenhouse effect was established by scientists more than a century ago. It would be impossible to explain the temperatures of Mars and Venus, as well as the Earth, without invoking this effect.
The "greenhouse effect" is part of a complex process -- a "balancing act" -- that makes life on earth possible. However, mankind's use of fossil fuels has led to a surplus of these gases, which prevents more radiation than usual from escaping back into space, thus making the planet hotter. This is not the slightest bit controversial in the scientific community, and the reverse is a vanishingly remote belief even among the climate deniosphere. For instance, the chairman of the industry-funded George C. Marshall Institute, a physicist who has conducted no climate research but suggests we should be "clamoring for more" carbon dioxide, has said that "most people like me believe that industrial emissions will cause warming, but just much less than has been predicted by many computer models." Indeed, industrial emissions have already caused substantial warming, as seen in this chart from NASA:
Fox News seized on a leaked draft of a U.N. climate report to suggest that climate change has been "overstated for the last 20 years." But the draft itself clarifies that observed temperatures over the last 20 years have fallen within the range of past projections despite natural short-term variation.
Fox & Friends First claimed "scientists say" that "global warming been overstated for the last 20 years," based on a draft of the fifth assessment report from the U.N. Intergovernmental Panel on Climate Change (IPCC). The report, which was leaked in December 2012 to a blog called "stopgreensuicide," contains a graph that conservative blogs claimed showed observed temperatures were lower than the projections of IPCC's first assessment report in 1990.
But scientists debunked this claim when the IPCC draft was first leaked in December. The draft itself notes that "Even though the 16 projections from the [previous temperature] models were never intended to be predictions over such a short time scale [1999-2010], the 17 observations through 2010 generally fall well within the projections made in all of the past assessments." Indeed, as climatologist James Annan told Media Matters in December, "The grey bounds [...] indicate the range of uncertainty including natural variability, and the observations are well within that range":
Conservative media outlets are claiming that a leaked draft of the UN climate panel's upcoming report undermines previous predictions of rapid warming driven by rising CO2 emissions. But scientists say these claims are "nonsense" and that the draft report only adds to the existing body of evidence that manmade climate change is a serious problem.
A draft of the Intergovernmental Panel on Climate Change (IPCC) fifth assessment report, due to be published in fall 2013, was leaked by Alec Rawls, a blogger who volunteered to review the report despite having no scientific expertise. In a blog post on Watts Up With That, Rawls claimed that the draft report contains a "game-changing admission" that galactic cosmic rays have significantly contributed to global warming, undermining the scientific consensus that climate change is driven by human activity. But experts say Rawls "completely misrepresented the IPCC report," noting that he ignored a paragraph that explicitly states there is "high agreement" among scientists that cosmic rays do not have a meaningful impact on global temperatures. Dr. Steve Sherwood -- a lead author of the chapter in question -- told Australia's ABC News that Rawls' claim is "ridiculous," adding: "we conclude exactly the opposite, that this cosmic ray effect that the paragraph is discussing appears to be negligible."
Furthermore, as Skeptical Science pointed out, even if cosmic rays did influence global temperatures, "they would currently be having a cooling effect." Dr. John Abraham of the Climate Science Rapid Response Team told Media Matters:
The IPCC report certainly was not saying the changes in the sun were causing the earth to warm. In fact, if the leaker was correct in his interpretation, the earth should be cooling right now!
But that didn't stop Investor's Business Daily from echoing his misinformation, claiming that the leaked draft "indicates the IPCC is actually admitting that a factor outside man's activities is playing a significant role in our climate." IBD quoted Rawls' claim that the section on cosmic rays "completely undercuts" the IPCC's conclusion that manmade climate change poses a significant threat, without noting that Rawls is not a scientist and has been thoroughly discredited.
Meanwhile, climate contrarian blogger Anthony Watts claimed to have discovered the real "bombshell" in the draft report: a chart comparing observed changes in global average surface temperatures with projections from the four previous IPCC reports. The chart indicates that early UN projections may have slightly overestimated warming because they did not take into account natural factors like solar forcing or aerosols, which tend to have a cooling effect. But the draft notes that "observations through 2010 generally fall well within the projections made in all of the past assessments."
Despite the overwhelming consensus among climate experts that human activity is contributing to rising global temperatures, 66 percent of Americans incorrectly believe there is "a lot of disagreement among scientists about whether or not global warming is happening." The conservative media has fueled this confusion by distorting scientific research, hyping faux-scandals, and giving voice to groups funded by industries that have a financial interest in blocking action on climate change. Meanwhile, mainstream media outlets have shied away from the "controversy" over climate change and have failed to press U.S. policymakers on how they will address this global threat. When climate change is discussed, mainstream outlets sometimes strive for a false balance that elevates marginal voices and enables them to sow doubt about the science even in the face of mounting evidence.
Here, Media Matters looks at how conservative media outlets give industry-funded "experts" a platform, creating a polarized misunderstanding of climate science.
The Economist has called the libertarian Heartland Institute "the world's most prominent think tank promoting skepticism about man-made climate change." Every year, Heartland hosts an "International Conference on Climate Change," bringing together a small group of contrarians (mostly non-scientists) who deny that manmade climate change is a serious problem. To promote its most recent conference, Heartland launched a short-lived billboard campaign associating acceptance of climate science with "murderers, tyrants, and madmen" including Ted Kaczynski, Charles Manson and Fidel Castro. Facing backlash from corporate donors and even some of its own staff, Heartland removed the billboard, but refused to apologize for the "experiment."
Heartland does not disclose its donors, but internal documents obtained in February reveal that Heartland received $25,000 from the Charles Koch Foundation in 2011 and anticipated $200,000 in additional funding in 2012. Charles Koch is CEO and co-owner of Koch Industries, a corporation with major oil interests. Along with his brother David Koch, he has donated millions to groups that spread climate misinformation. Heartland also receives funding from some corporations with a financial interest in confusing the public on climate science. ExxonMobil contributed over $600,000 to Heartland between 1998 and 2006, but has since pledged to stop funding groups that cast doubt on climate change.
Despite their industry ties and lack of scientific expertise, Heartland Institute fellows are often given a media platform to promote their marginal views on climate change. Most visible is James Taylor, a lawyer with no climate science background who heads Heartland's environmental initiative. Taylor dismisses "alarmist propaganda that global warming is a human-caused problem that needs to be addressed," and suggests that taking action to reduce emissions could cause a return to the "the Little Ice Age and the Black Death." But that hasn't stopped Forbes from publishing his weekly column, which he uses to spout climate misinformation and accuse scientists of "doctoring" temperature data to fabricate a warming trend. It also hasn't stopped Fox News from promoting his misinformation.
Fox News is promoting a report from a British tabloid to claim that new data shows "Global Warming [Is] Over." But the agency that released the data explained that the tabloid report is "misleading" because it is based on a short-term period that obscures the long-term upward trend in global temperatures.
Anonymous hackers recently released another batch of emails taken from a climate research group at the University of East Anglia in 2009, along with a document containing numbered excerpts of purportedly incriminating material. Many of these selections have been cropped in a way that completely distorts their meaning, but they were nonetheless repeated by conservative media outlets who believe climate change is a "hoax" and a "conspiracy."
In response to the suspension of federal scientist Charles Monnett, who authored a 2006 article documenting polar bear deaths, conservative media have claimed that the case exposes "the global warming fraud" and that polar bears are not threatened by climate change. In fact, extensive research establishes that polar bears are vulnerable to extinction due to decreasing sea ice, and human-induced global warming is supported by a robust body of evidence independent of any polar bear studies.
