MEDFORD, Ore. -- One of the key figures of the landmark climate change lawsuit, Juliana v. United States updated the Rogue Valley on the case’s progression, Sunday. 21 young people filed that lawsuit with Our Children's Trust back in 2015.

Kiran Oommen has been giving speeches at different churches across the nation. Sunday, he was invited to do just that at the Medford Congregational United Church of Christ. He spoke about why he thinks it is important to protect the Earth.

"We argue that in order to uphold our constitutional rights to life, liberty and property, a stable climate is essential," Oommen said in his speech. "We are part of the environmental movement. We're not going to see the Earth. We are doing our part to contribute to a much larger movement that includes Standing Rock, that includes … everyone that's doing stuff, that includes the church community."

The lawsuit argues the government is violating their rights by not reducing carbon dioxide emissions. It’s goal is for the government to create a science based recovery plan. Oommen said that's a plan to help get the US to do its part in reducing those emissions.

"It'll connect our constitutional rights with the degradation of the climate. It will enshrine it into law that the effects that of climate change are hurting people and that is a violation of their constitutional rights and fundamental rights," Oommen said.

The case hasn't gone to trial as planned yet as the US government has been recently granted a delay.
