PROVIDENCE, R.I. (AP) — U.S. Sen. Sheldon Whitehouse has now preached the dangers of climate change from the Senate floor 100 times.

The Rhode Island Democrat gave his 100th “Time to Wake Up” speech Monday.

In prepared remarks, Whitehouse reflected on the mounting effects of carbon pollution. He discussed the political obstacles to addressing climate change, notably pressure from the fossil fuel industry stifling Republican cooperation.

He says his top reason to act is Rhode Island, the “Ocean State.”

Whitehouse wants to impose a fee on carbon emissions. He plans to announce details in June.

He’s hopeful public pressure will lead to the passage of comprehensive climate change legislation.

Whitehouse gave his first speech in the series April 18, 2012.

He says he wants to shine light on the facts, science, and the polluters’ “scheme of denial.”
