David Roberts is a strong authority for this TED Talk because he was a staff writer at Grist, a well-known environmental news publication focused on climate and energy issues. He's had lots of experience reporting on climate science and policy, giving him more credibility to be the one addressing these issues.

His objectivity is not very neutral, as he is an advocate for climate activism and advocates for translating science to the general public in simpler terms to push more awareness. He is trying to be persuasive and get his listeners o understand that climate change is an urgent issue and action is needed quick. He says, "we have to do something or we're screwed", showing his persuasive speaking style and his motive to get action/change from this, not just talk.

David Roberts was a staff writer at Grist.org, which covered environmental news and published commentary on climate-related issues, which indicates bias, along with the event being hosted between TEDx and The Evergreen State College. Roberts has spoken frequently on climate changes but has expressed that he is not an environmentalist. Roberts expresses information and presents it in a persuasive manner with the purpose of trying to convince others to care more about climate-related issues, emphasizing how in the past, the Earth’s climate has only varied in a narrow margin until recently. Roberts backs up his claims with sources but is clearly expressing his desire to convince the audience to care about climate change as he does, which does show his bias.
