WASHINGTON, D.C. - Oklahoma Senator Jim Inhofe brought a snowball to the U.S. Senate chamber Wednesday during a speech questioning the science behind man-made climate change.

"Do you know what this is? It's a snowball," Inhofe said, holding the snowball aloft. "It's just from outside here, so it's very, very cold out ... very unseasonable."

"Mr. President, catch this," he said, tossing the snowball away. An Inhofe aide told National Journal the snowball was caught by a congressional page.

Inhofe, the chairman of the Senate Environment and Public Works Committee, has long argued that man-made climate change is a hoax, and he's opposed the Obama administration's efforts to reduce carbon emissions.

He brandished his snowball prop during a broader speech questioning global warming.
