Yes, There Is A 97% Scientific Consensus on Climate Change

Climate Change Consensus Skeptical Science

Earlier today David Robertson defended Republicans for their anti-scientific viewpoint in denying the scientific consensus on climate change at The Moderate Voice, where many of my posts are also posted. Dorian De Wind followed up, citing work by NASA to debunk what David wrote on the science. As this part of the debate has already been answered, I will address a more specific claim that there is no consensus. Climate change denialists typically make one of two related arguments, either denying that there is a strong consensus among climate scientists or denying the entire concept of a scientific consensus.

David quoted a paper by science fiction writer Michael Crichton denying the concept of a scientific consensus. Crichton is not a climate scientist, but  is a well known denier of climate science. Both his view on the scientific consensus and his arguments against climate change have frequently been debunked. As a fellow physician, he should have known very well that the use of consensus statements is common in science.  Consensus papers are actually extremely common in medicine, as experts in a field decide what the best evidence shows to guide those providing medical care. For example, a quick Google search will show what seems like an endless number of consensus statements from the National Institute of Health. This is just one of many organizations which has issued consensus statements in health care, and other scientific fields also commonly use consensus statements.

Reaching a scientific consensus does matter beyond the scientific community. For example, the scientific consensus on climate change has often been compared to the scientific consensus that cigarette smoking causes cancer. This consensus has resulted in both a change in attitude by the general public and a change in laws regarding cigarette smoking. A comparable change is necessary to respond to the scientific consensus on climate change.

There is a scientific consensus on climate change, and NASA has described it:

Multiple studies published in peer-reviewed scientific journals show that 97 percent or more of actively publishing climate scientists agree: Climate-warming trends over the past century are very likely due to human activities. In addition, most of the leading scientific organizations worldwide have issued public statements endorsing this position. The following is a partial list of these organizations, along with links to their published statements and a selection of related resources.

The report then goes on to cite statements from several organizations and includes this list of almost two hundred organizations which take the position that climate change has been caused by human action.

Skeptical Science has also reviewed the claims that there is no scientific consensus on climate change, debunking such arguments. Their findings were consistent with what NASA and other scientific organizations have reported on the scientific consensus on climate change. They note that, “A survey of over 12,000 peer-reviewed climate science papers by our citizen science team at Skeptical Science has found a 97% consensus in the peer-reviewed literature that humans are causing global warming.”

Mike Huckabee Backs Instituting Slavery For The Poor

There were certainly opinions I disagreed with in this weeks’ Democratic debate, but no views were expressed which were totally off the wall. Republicans provide a steady stream of such opinions, often with the worst coming from those who prefer religious law to secular American law. Think Progress reports that Mike Huckabee even agreed with instituting slavery in a recent interview:

Host Jan Mickelson began by bemoaning that the “criminal justice system has been taken over by progressives.” In order to fight back, he argued, conservatives should look to the biblical Book of Exodus. “It says, if a person steals, they have to pay it back two-fold, four-fold,” Mickelson explained. “If they don’t have anything, we’re supposed to take them down and sell them.”

Mickelson went on to argue why jails, which he claimed are a “pagan invention,” are inferior to slavery: “We indenture them and they have to spend their time not sitting on their stump in a jail cell, they’re supposed to be working off the debt.”

“Wouldn’t that be a better choice?” the host asked.

“Well, it really would be,” Huckabee replied without missing a beat. “Sometimes the best way to deal with a nonviolent criminal behavior is what you just suggested.”

Huckabee, who was a Baptist pastor before entering politics, is no doubt familiar with the Exodus 22:3 passage to which Mickelson referred: “Anyone who steals must certainly make restitution, but if they have nothing, they must be sold to pay for their theft.”

But U.S. law, unlike biblical penal prescriptions, forbids selling human beings like chattel. The United States also bans debtors’ prisons and the Supreme Court has ruled that it is unconstitutional to imprison people who are too destitute to pay court fines. (Contra these bans, manylocalities are being sued for still running debtors’ prisons.)

Considering that Huckabee is not the only member of the religious right running for the Republican nomination, maybe the candidates should be asked about slavery, and perhaps other aspects of Biblical law, at the next debate. They might have to do something to keep the debate lively with Donald Trump threatening not to participate if he does not get his way on the rules.
