Boston Globe Columnist Jeff Jacoby Distorts Survey And Study To Deny Climate Consensus

This is a guest post by Climate Nexus, and originally appeared on Climate Science Watch.

Jeff Jacoby’s recent Boston Globe op-ed misses the mark on the climate consensus. His argument boils down to the claim that there’s no consensus among scientists on the causes and effects of global warming – plus, the very idea of consensus is “authoritarian and anti-scientific” anyway. Both parts of this assertion completely mischaracterize the way that science works, using previously debunked factoids that don’t belong in a news outlet of this prominence. Climate scientists agree that human activity is warming our planet, and that this is causing harmful impacts that will get worse if we do nothing.

A few examples show the thinness of Jacoby’s justification:

Meteorologists actually support the facts of human-caused climate change. Jacoby cites a recent survey of the American Meteorological Society, even though the study authors themselves have already spoken up to directly refute his interpretation of their work. In fact, 73% of AMS members surveyed agree that human activities have contributed to warming, and that number rises among those with greater scientific expertise. Among meteorologists actively publishing on climate topics, 93% agreed.

Furthermore, meteorologists are just a subset of the scientific community. The 93% consensus among meteorologists does not refute the 97% consensus (established via multiple different survey methods) among the broader climate science community that humans are warming our climate.

Climate Change Spin A Growing Problem For Fox News

When it comes to climate change denial, a new study shows that the folks at Fox News are leading the pack. Through politically-charged news segments and commentary, Fox News personalities are helping spread misinformation about climate change while convincing their viewers that scientists are torn on the issue.

The International Journal of Press/Politics has published a new study titled “Climate on Cable: The Nature and Impact of Global Warming Coverage on Fox News, CNN, and MSNBC,” [PDF] which details the ways in which the major American news outlets are reporting stories on climate change.

From the report:

National surveys reveal that many Americans do not believe that scientists are in agreement over this issue. More troubling, the number of Americans who believe that global warming is happening and that it is a result of human activities has declined in recent years: In April 2008, 71 percent of Americans perceived solid evidence for global warming, relative to only 57 percent in October 2009. And while President Obama has pledged that passing legis- lation to curb pollution that contributes to global warming is a priority of his admin- istration, in January 2009, Americans ranked global warming last in a list of twenty policy issues that they felt were important for the president and Congress to address. These surveys also point to stark partisan divides in global warming perceptions, with Democrats far more likely to accept the evidence for the human causes of global warming and to consider environmental protection a policy priority than Republicans.

The views that many Americans have towards climate change are clearly reflected in the cable news arena. Fox News, sadly, has the highest ratings of any other cable news organization, and the study shows that their viewers are for more likely to believe that manmade climate change isn’t happening. More from the study:

Of the three networks, Fox News was simultaneously the least likely to be accepting and the most likely to be dismissive of climate change. Nearly 60 percent of Fox News broadcasts were dismissive of climate change, whereas less than 20 percent were accepting of climate change. On the other hand, more than 70 percent of CNN and MSNBC broadcasts were accepting of climate change. Not a single MSNBC broadcast took a dismissive tone toward climate change and just 7 percent of CNN broadcasts did so.
