Shaye Wolf, climate science director for the Center for Biological Diversity, warns time is running out to get carbon dioxide pollution under control in a
letter to the editor.
As a scientist and a mom, I am horrified that carbon dioxide concentrations in the atmosphere just hit a record high. Arctic monitoring stations are reporting that levels of this heat-trapping gas have reached 400 parts per million — putting the world at increasing risk of catastrophic climate change.
We're already experiencing dangerous warming. The U.S. just experienced its hottest spring on record, and the decade from 2000 to 2010 was the warmest on record.
Our kids face a tough future. As the Earth warms, excessive heat, extreme weather, and rising sea levels will threaten agriculture and fresh water supplies, our coastal cities, our planet's biodiversity, and the welfare and lives of hundreds of millions of people around the globe.
But there's still time to get a handle on this dangerous problem. The EPA must get serious about using the Clean Air Act to reduce carbon dioxide pollution from existing power plants. We need a national emissions limit that will help us get carbon dioxide concentrations back down to 350 parts per million — the level needed to avoid many dangerous impacts.
Our children are depending on us to get carbon dioxide pollution under control. When I look in my daughter's eyes, I know we can't let them down.
