President Barack Obama's inaugural address pledge to "respond to the threat of climate change, knowing that the failure to do so would betray our children and future generations" ("Climate Change Given Prominence in Obama's Address," Jan. 21) was a clear sign that he understands the urgency of addressing this problem. Now we're counting on him to follow up those words with action.
We know what we need to do in Pennsylvania and nationwide to tackle global warming: clean up the largest sources of the carbon pollution fueling the problem. And with the president's leadership, we can make that happen. Right now, President Obama and the Environmental Protection Agency are developing the first-ever carbon pollution limits for new power plants -- a truly historic step toward cleaning up the single biggest source of carbon pollution.
A record number of Americans have already spoken out in support of the proposed standards, and more and more opinion leaders are echoing the need for action. I urge the EPA to finish the job on these standards and also develop standards for existing power plants. Our health and our environment are depending on it.
