It’s Time to Get Real About Climate Protection

23

“Since 1997 Colorado has installed nearly $4 billion worth of wind turbines and solar panels. These investments in a clean energy economy are a tremendous accomplishment.”

“But you will know we are serious about tackling climate change when we begin focusing on reducing METHANE emissions, not just on carbon dioxide.”

Randy Udall

2012: Hottest Year Ever for Lower 48Science Magazine

recently published a study showing that

methane and soot reduction would have the most significant,

immediate, and cost effective impact on global warming.
