With the sun baking Pennsylvania Avenue on Saturday afternoon, thousands of people pounded the pavement as it radiated the day’s record-setting heat to warn about the dangers of climate change.

More than 200,000 people showed up to the People’s Climate March, according to organizers’ estimates. They paraded down the city’s most prominent avenue, starting near the Capitol, marching past the Trump International Hotel with booing and cries of “shame,” to encircle the White House.

Although temperatures soared into the 90s, about 20 degrees above normal, there weren’t scenes of mass dehydration or the confused chaos that sometimes comes with large-scale mobilizations. There were plenty of bathrooms and drums of free water lining the way.

Groups were organized into issue blocs, patiently lined up to start marching promptly at the designated time, with indigenous groups leading the way.

“Were working to preserve our wins and move forward a proactive agenda as much as we can,” Paul Getsos, the national coordinator for the People’s Climate Movement, told DCist.

Meanwhile, a Ben & Jerry’s truck handed out ice cream under a sign that warned: “if it’s melted, it’s ruined.” People licked it down quickly, racing to beat the day’s unseasonable heat.

“Whose planet?” asked one popular chant. “Our planet.”
