AUDIE CORNISH, HOST:
And I'm Audie Cornish. Today at noon, America's oldest working clock tower rang out for the first time since the 1800s.

CORNISH: Old South Meeting House in Boston was a Puritan gathering place. Ben Franklin was baptized there and the Boston Tea Party was planned there, but the belfry has been silent since 1876, after the brick building was nearly destroyed in the great Boston fire.
Politically, climate change is off this year's campaign agenda. Jobs, the economy and social issues are front and center.
But scientists are working as hard as ever to figure out how much the Earth is warming and what to do about it. Some now say it's time for a new strategy, one that gets faster results.
Talk to Durwood Zaelke, for example. Zaelke is a grizzled veteran of the climate wars: He was in Kyoto in 1997 when the world's nations drafted a treaty promising to curb warming, and he has watched that promise fizzle while the planet's temperature continues to rise.
The "Battle Over Bain" has become a hot topic at the U.S. Chamber of Commerce, a key player in politics.
U.S. Chamber of Commerce President Tom Donohue says he is "disappointed" that some GOP presidential candidates are attacking front-runner and former Massachusetts Gov. Mitt Romney for his work at Bain Capital in the 1990s.
As the presidential campaign kicks into high gear, a fight is brewing over stricter voting laws that could affect turnout and influence general election results in battleground states.
New laws in several states will require millions of voters to show photo identification when they cast ballots this year, the result of a nationwide push mostly by Republicans who claim the measures will prevent election fraud. Democrats and voting rights activists oppose the laws, arguing that they are unnecessary because voter fraud is rare.
