Next week is Climate Week in New York City. The happenings begin on Sunday with what promises to be a massive march demanding action to curb human-propelled global warming. On Tuesday, the United Nations will hold an all-day climate-focused summit for world leaders.

Each day will also brim with meetings, panels, and exhibits on climate change, energy, and resilience happening all over town. PopSci will be covering the summit and the best of the rest, so check back here for updates.

Tuesday's climate summit is being held at UN headquarters, but isn't officially part of the existing international climate treaty process (the United Nations Framework Convention on Climate Change, or UNFCCC). So it's not going to end with a unified international statement on how we'll curb global warming.

But organizers hope that it will help those negotiations, by amping up the momentum for getting a strong agreement in late 2015, at the official climate talks in Paris – an agreement that must do more than current international efforts if we're to keep the average future temperature increase below 2 degrees Centigrade.
