In 2010, a well-known environmental consultant warned that global warming was a danger to the environment, and urged Americans to consider a carbon tax, a policy that is now gaining support from both the left and the right.
The report, written by climate scientist James Hansen, was released at the height of the 2008 recession.
It also became a rallying cry for many environmentalists.
“The world has been experiencing dangerous climate change for a very long time, and the world needs to act,” Hansen said.
“If we don’t act, the planet will go to the brink of extinction.”
Hansen’s warnings were based on a study published in 2009 in the journal Science that showed that CO2 emissions from fossil fuels would increase dramatically in the coming decades.
That led Hansen to argue that we were in for “a major climate change event” that would “have profound and irreversible effects.”
The report was based on Hansen’s theory, but it didn’t have enough peer-reviewed research to prove that it was accurate.
In addition to that, Hansen had not published his results in peer-review journals, so they could not be independently verified.
Hansen also had a financial stake in the study.
His business, Hansen Enterprises, was founded by his late wife, Jane.
As the company grew, Hansen also took on more corporate and political roles.
At one point, Hansen’s wife sold her shares in the company to fund his climate research.
The company also became one of the largest investors in a campaign that would win a $20 million award in a landmark climate change lawsuit, in which more than 20 million people around the world signed a petition.
In 2010 and 2011, Hansen was named by President Obama to serve on the Intergovernmental Panel on Climate Change.
In 2011, after the election of Donald Trump, Hansen said that the president’s campaign would push for the carbon tax.
Trump has not followed through on that promise.
Climate change denial and politics have become increasingly contentious topics in recent years, with climate change deniers on the left increasingly vocal, while conservatives on the right have been more cautious.
The recent election of Trump’s chief of staff, Anthony Scaramucci, has created an environment in which many climate scientists are more concerned with defending the Republican president’s agenda than they are defending their own work.
In a statement to Business Insider, the White House said that it would be reviewing Hansen’s work and would not be commenting further.
