Texas will decide Friday whether to include language denying manmade climate change in its latest science text books.

Earlier today, some publishers agreed to correct or remove inaccurate passages that suggest humans may not be the real source of climate change. Each publisher makes its own decisions about what specific content to include in the textbooks it submits for adoption.

But Dan Quinn, communications director of civil liberties group Texas Freedom Network (TFN), told Fusion that "things can still change between now and the final vote on Friday."

Here's a screenshot of the proposed section for the book, which would also be sold in other states. It cites a report from Heartland Institute, a conservative nonprofit organization that has received funding from at least one Koch brother, as a "primary source."

And here's the transcript for the denialist part:

“Is Global Warming a Result of Human Activity?:

Scientists agree that Earth’s climate is changing. They do not agree on what is causing the change. Is it just another natural warming cycle like so many cycles that have occurred in the past? Scientists who support this position cite thousands of years’ worth of natural climatic change as evidence. Or is climate change anthropogenic—caused by human activity? Scientists who support this position cite the warming effect of rapidly increasing amounts of greenhouse gases in the atmosphere. Greenhouse gases occur naturally, but they also result from the burning of fossil fuels. Which side’s evidence is more convincing?

No!

PRIMARY SOURCE

‘The Intergovernmental Panel on Climate Change (IPCC), an agency of the United Nations, claims the warming that has occurred since the mid-twentieth century ;is very likely due to the observed increase in anthropogenic greenhouse gas concentrations.' Many climate scientists disagree with the IPCC on this key issue.

Scientists who study the issue say it is impossible to tell if the recent small warming trend is natural, a continuation of the planet’s recovery from the more recent “Little Ice Age,” or unnatural, the result of human greenhouse gas emissions. Thousands of peer-reviewed articles point to natural sources of climate variability that could explain some or even all of the warming in the second half of the twentieth century. S. Fred Singer and Dennis Avery documented natural climate cycles of approximately 1,500 years going back hundreds of thousands of years.’

"This entire section is misleading," TFN warns in its report on the text. "Scientists do not disagree about what is causing climate change, the vast majority (97%) of climate papers and actively publishing climatologists (again 97%) agree that human activity is responsible."

TFN live-blogged a Wednesday hearing on the changes. After it wrapped up, TFN President Kathy Miller released the following statement:

"It wouldn’t be a Texas textbook adoption without a flurry of last-minute objections from board members and political activists without any expertise on the subject at hand. On issues like bashing Islam and questioning the existence of global warming, we heard a lot of personal and political opinions but no actual facts that would justify revising what the textbooks currently say on those subjects.”
