The long-awaited People's Climate March is happening right now. What is it, you ask? More than 100,000 people are marching in New York City today, displaying a vivid sign of unity and communicating public frustration over stalled efforts to curb carbon dioxide emissions. According to the New York Times, the two-mile march is scheduled to take place in Midtown Manhattan at 11:30am.

It will begin moving east along 59^th street from Columbus Circle, and is expected to draw a myriad of people including labor and immigrant groups, students and politicians, and scientists and religious leaders. The march takes place two days before a climate summit at the United Nations, which President Obama is expected to attend.

Bill McKibben, one of the march's lead organizers and a former "New Yorker" staff writer, stated, "Everyone in this movement who heard Ban Ki-Moon's call for world leaders to come to New York City had the same thought: These guys are going to come and do the same thing they always do - offer a few fine speeches and head home having accomplished nothing. We figured we would invite ourselves to come along and try to press them harder than they've been pressed before. We don't expect this will have immediate results here in New York, but we think building a big movement is the only way to get them off the dime," explaining the movement's purpose and motivations.

Climate change is a very real and troublesome factor - last week, meteorologists at the National Oceanic and Atmospheric Administration announced that this year's June, July, and August were the hottest months on record for the globe.

Sam Barratt, a campaign director for the online advocacy group Avaaz, commented, "Climate change is no longer an environmental issue; it's an everybody issue... the number of natural disasters has increased and the science is so much more clear. This march has many messages, but the one that we're seeing and hearing is the call for a renewable revolution."
