The
political war over climate science is flaring up again on Capitol Hill
this week as the U.S. Senate debates a bill that would approve the
highly controversial Keystone XL pipeline. Pipeline opponents, many of
whom oppose the project because they say it would accelerate climate
change, are trying to secure votes on a number of largely symbolic
amendments affirming the Senate’s belief that climate change is real
and human-caused and that policymakers should address it. ... Senators
Bernie Sanders (I–VT), Brian Schatz (D–HI), Jeff Merkley (D–OR), Tim
Kaine (D–VA), and Sheldon Whitehouse (D–RI) all have filed
climate-related amendments. And Democrats aren’t hiding the reasoning
behind their strategy. “We're going to have a vote to find out who the
climate change deniers in the U.S. Senate really are,” said Senator
Charles Schumer (D–NY), the third-ranking Senate Democrat, during a
Capitol Hill press conference today. “Do they deny that human activity
has helped create climate change? Stay tuned. We'll see.”
