Naomi Seibt, a 19-year-old German YouTube 'influencer' claims to promote 'climate realism' over 'climate alarmism' on YouTube

She will be speaking at CPAC in Washington D.C. and join a libertarian think tank and lobbying group that promotes climate change skepticism 

Seibt joined the Heartland Institute's Center on Climate and Environmental Policy in February in order to spread her message

The Heartland Institute is one of the most notorious climate change denial groups in the United States

She has been described as a climate-skeptic answer to Greta Thunberg, 17, the environmental activist from Sweden who inspired international climate protests

Thunberg was named Time Magazine's Person of the Year and has become the face for youth climate action
