According to Mitch McConnell, Senate Majority leader, the answer is yes:
Senate Majority Leader Mitch McConnell (R-Ky.) said Tuesday he will allow the Senate to vote on an amendment asking if they agree that climate change is impacting the planet.
At his weekly press briefing, McConnell said "nobody is blocking any amendments" to legislation that would approve construction of the Keystone XL pipeline.
"Sanders’ office sends over the text of the amendment. It reads:
It is the sense of Congress that Congress is in agreement with the opinion of virtually the entire worldwide scientific community and a growing number of top national security experts, economists, and others that –
(1) climate change is real;
(2) climate change is caused by human activities;
(3) climate change has already caused devastating problems in the United States and around the world; and
(4) it is imperative that the United States transform its energy system away from fossil fuels and toward energy efficiency and sustainable energy."
Put them on the record. Give them enough rope.
