Thousands bare the elements to partake in March for Science in Washington D.C.

The March for Science at the National Mall attracted tens of thousands to share their views about the current political climate despite rainy conditions.

Rain poured over Washington D.C. on Saturday as scientists and citizens alike, carrying a variety of protest signs, flocked to the foot of the Washington Monument. Hundreds of scientific organizations and universities signed on to partner with the march as dozens of musical acts and speakers performed throughout Saturday.

The day-long celebration of science was organized by the Earth Day Network, meant to encourage policy-makers to use scientific evidence to craft legislation. It was hosted by musician Questlove and YouTube personality Derek Muller.

The march also had three honorary co-chairs, including Dr. Mona Hanna-Attisha, the pediatrician and health advocate fighting for clean water in Flint, Michigan; Dr. Lydia Villa-Komaroff, one of the first Mexican-Americans to earn a PhD in the natural sciences, and famed children's educator and best-selling author Bill Nye. Nye is currently the CEO of the Planetary Society- one of the march's partners- and star of the new Netflix series Bill Nye Saves the World.

Marches were also organized in several cities around the country and around world, including New York, Los Angeles, Chicago, London and Berlin.

"The March for Science is a celebration of science. It's not only about scientists and politicians," the website read. "It is about the very real role that science plays in each of our lives."
