NEW YORK (AP) — A Manhattan skyscraper that is home to The New York Times became the site of twin daredevil stunts Thursday, with two men scaling the 52-story office tower within a matter of hours.

The first man, Alain Robert, unfurled a banner as he climbed that said "Global warming kills more people than a 9/11 every week." He was arrested when he made it to the top.

Hours later, a second man ascended the building — a stunt that drew the attention of thousands of onlookers, along with TV cameras that captured the drama in real time. Crowds on the street pressed against police barricades to watch, and people clapped and cheered for the climber while snapping pictures on their cellphones.

He, too, was taken into custody as he reached the top. Police said he was charged with reckless endangerment, criminal trespass and disorderly conduct and was awaiting arraignment overnight.

"Only in New York. This is why I live in New York," said 29-year-old Emily Perschetz, who watched the second climber for about 20 minutes.
