Hundreds of people gathered at Clinton Park on Houston's east side Saturday to protest climate change and promote environmentally focused policies on President Donald Trump's 100th day in office.

The demonstrators called for Environmental Protection Agency funding, continued participation in the Paris climate agreement and greater investments in alternative forms of energy and transportation. Many carried signs targeting climate change deniers and members of the Trump administration who have questioned that science.

"Climate change in very much real," said Houston Mayor Sylvester Turner. "You would think in April 2017 that would be an established issue."

The event occurred a week after the first March for Science, global demonstration that drew thousands of people in Houston and other cities on Earth Day. There, marchers called for fact-based approaches to climate change and environmental protection, among other things.
