From the New York Times:
Critics of the teaching of evolution in the nation’s classrooms are gaining ground in some states by linking the issue to global warming, arguing that dissenting views on both scientific subjects should be taught in public schools.
In Kentucky, a bill recently introduced in the Legislature would encourage teachers to discuss “the advantages and disadvantages of scientific theories,” including “evolution, the origins of life, global warming and human cloning.”
The bill, which has yet to be voted on, is patterned on even more aggressive efforts in other states to fuse such issues. In Louisiana, a law passed in 2008 says the state board of education may assist teachers in promoting “critical thinking” on all of those subjects.
Last year, the Texas Board of Education adopted language requiring that teachers present all sides of the evidence on evolution and global warming.
Oklahoma introduced a bill with similar goals in 2009, although it was not enacted.
The linkage of evolution and global warming is partly a legal strategy: courts have found that singling out evolution for criticism in public schools is a violation of the separation of church and state. By insisting that global warming also be debated, deniers of evolution can argue that they are simply championing academic freedom in general.
Yet they are also capitalizing on rising public resistance in some quarters to accepting the science of global warming, particularly among political conservatives who oppose efforts to rein in emissions of greenhouse gases.
In South Dakota, a resolution calling for the “balanced teaching of global warming in public schools” passed the Legislature this week.
“Carbon dioxide is not a pollutant,” the resolution said, “but rather a highly beneficial ingredient for all plant life.”
The measure made no mention of evolution, but opponents of efforts to dilute the teaching of evolution noted that the language was similar to that of bills in other states that had included both. The vote split almost entirely along partisan lines in both houses, with Republican voting for it and Democrats voting against.
For mainstream scientists, there is no credible challenge to evolutionary theory. They oppose the teaching of alternative views like intelligent design, the proposition that life is so complex that it must be the design of an intelligent being. And there is wide agreement among scientists that global warming is occurring and that human activities are probably driving it. Yet many conservative evangelical Christians assert that both are examples of scientists’ overstepping their bounds...
Lawrence M. Krauss, a physicist who directs the Origins Initiative at Arizona State University and has spoken against efforts to water down the teaching of evolution to school boards in Texas and Ohio, described the move toward climate-change skepticism as a predictable offshoot of creationism.
“Wherever there is a battle over evolution now,” he said, “there is a secondary battle to diminish other hot-button issues like Big Bang and, increasingly, climate change. It is all about casting doubt on the veracity of science — to say it is just one view of the world, just another story, no better or more valid than fundamentalism.”
Not all evangelical Christians reject the notion of climate change, of course. There is a budding green evangelical movement in the country driven partly by a belief that because God created the earth, humans are obligated to care for it.
Yet there is little doubt that the skepticism about global warming resonates more strongly among conservatives, and Christian conservatives in particular.
