Story highlights Leonardo DiCaprio met with President-elect Trump to discuss climate change and green energy jobs

Despite meeting with the DiCaprio and another famous environmentalist, Al Gore, Trump has sent mixed signals about how seriously he will take the threat of climate change

Trump's pick to head the EPA in his administration has questioned the science behind climate change

(CNN) Leonardo DiCaprio met with President-elect Donald Trump on Wednesday to discuss climate change -- adding to the mixed signals from the President-elect on the environment.

"We presented the President-elect and his advisors with a framework ... that details how to unleash a major economic revival across the United States that is centered on investments in sustainable infrastructure," Terry Tamminen, CEO of the Leonardo DiCaprio Foundation, said in a statement. "Our conversation focused on how to create millions of secure, American jobs in the construction and operation of commercial and residential clean, renewable energy generation.

DiCaprio's meeting with Trump only added to the mixed messages coming out of Trump Tower, particularly on the issue of climate change.

On the same day of his meeting with DiCaprio, Trump tapped Oklahoma attorney general Scott Pruitt -- a climate change denier -- to head the Environmental Protection Agency. Pruitt is an opponent of many of the Obama EPA's environmental regulations, and sued the agency over its regulations of power plants in his capacity as attorney general.

Coupled with Trump's own history of climate change skepticism, environmentalists see dim prospects for action that scientists say is necessary to avert the most devastating consequences of climate change. Trump has called climate change a "hoax" but in a recent interview allowed for the possibility that human activity may be contributing to global warming.
