改变气候英语作文

RENEE MONTAGNE, HOST:It's MORNING EDITION from NPR News. Good morning, I'm Renee Montagne.

DAVID GREENE, HOST:And I'm David Greene.

New federal standards for K through 12 science education are due out soon. This is the first since the mid-'90s. And for the first time, the guidelines advise teaching students about climate change.

As NPR's Jennifer Ludden reports, it's expected to fill a big gap.

JENNIFER LUDDEN, BYLINE: By the time today's students grow up,

the challenges posed by climate change are expected to be severe and sweeping. Yet, polls show they know little of it.

Mark McCaffrey is with the National Center for Science Education.

MARK MCCAFFREY: Only one-in-five feel like they've got a good handle on climate change from what they've learned in school. So the state of climate change education in the U.S. is abysmal.

LUDDEN: We all learn the water cycle. But how many can draw a picture of the carbon cycle? With plants taking in carbon to grow, then dying and eventually turning into fossil fuels like coal and oil, which then put carbon back into the atmosphere when burned. Even when this is taught, McCaffrey says climate is often sidelined. Why take Earth science, when you need biology and chemistry to get into college?

On top of this, there's the political battle over how climate change is taught. Last month, Colorado state lawmakers considered a

so-called Academic Freedom Act.

JOSHUA YOUNGKIN: The bill will go toward creating an atmosphere

of open inquiry.

LUDDEN: That's Joshua Youngkin of the Discovery Institute, which helped write the bill. It's the same group that's questioned evolution, and the way it's taught. Now the institute is targeting global warming. Though Youngkin told lawmakers the aim is not to ban climate change from the classroom.

YOUNGKIN: It just gives teachers a simple right. To know that they can teach both sides of a controversy objectively, in a

scientific manner, in order to induce critical thinking in their student body.

LUDDEN: But critics point out there is no controversy within science. Climate change is happening and it's largely driven by humans. This hasn't stopped 18 states from considering these academic freedom bills - seven this year. So far, only Tennessee and Louisiana have passed them.

Still, say educators, since climate change has been politicized, many teachers avoid it altogether. Or, they do teach two sides. One day, it's Al Gore's "An Inconvenient Truth."

(SOUNDBITE OF DOCUMENTARY, "AN INCONVENIENT TRUTH")

AL GORE: Starting in 1970, there was a precipitous drop-off in the amount, and extent and thickness of the arctic ice cap.

LUDDEN: And the next, "The Great Global Warming Swindle."

(SOUNDBITE OF DOCUMENTARY, "THE GREAT GLOBAL WARMING SWINDLE")

UNIDENTIFIED MAN: Each day the news reports grow more

fantastically apocalyptic.

LUDDEN: The end result for students: Confusion. The new science guidelines could provoke more push back. James Taylor is a senior fellow with the Heartland Institute. The free market think tank is working on its own curriculum, questioning man's role in global warming.

JAMES TAYLOR: To the extent that these standards do paint a picture that I think runs counter to the scientific evidence, we're going to make sure that we point that out.

LUDDEN: The new science standards are voluntary. But 26 states helped develop them and about 40 say they're likely to adopt them.
