Daryl Hannah: Politicians Are 'Cowards' For Failing To Speak Out On Climate Change

Actress Daryl Hannah criticized the lack of political dialogue on climate change Wednesday, especially from the Obama administration.

"Since when did science get so politicized?" Hannah said Wednesday at a trade show in Baltimore, Maryland, according to Get Energy Smart! NOW! "It isn’t like these scientists are pocketing money on climate science like political consultants are with Citizens United funds. Firemen don’t ask themselves whether a house is really burning when they see flames coming out the window and hear a child screaming. This is reality."

"They’re cowards," Hannah added, referring to politicians who fail to speak about the subject.

Hannah has a long history of environmental activism, including being arrested last year outside the White House while protesting the Keystone XL pipeline and calling on President Barack Obama to oppose the oil industry.
