Last week's report by the Intergovernmental Panel on Climate Change (IPCC) - the leading global body evaluating climate change - warned the world was heading towards a temperature rise of 3 degrees Celsius.
President Donald Trump is backing off his claim that climate change is a hoax but says he doesn't know if it's manmade and suggests the climate will "change back again". I don't wanna give trillions and trillions of dollars.
"So I always used to say the toughest people are Manhattan real estate guys and blah, blah", he said.
His comments on Sunday came less than a week after the publication of a landmark United Nations report which said "human activities" had already caused global warming of approximately one degree Celsius since pre-industrial times. "I don't wanna lose millions and millions of jobs", Trump said in an interview with the CBS broadcaster. "I don't want to be put at a disadvantage".
'You would have to show me the scientists because they have a very big political agenda, ' Trump replied. The president said a speech in which he mocked her testimony helped the Supreme Court nominee get across the line, but Trump denied he was making fun of her.
Per the IPCC report, limiting global warming to a 2 degrees Celsius would require CO2 emissions to drop by around 20% from 2010 levels by 2030 and reaching "net zero" (through the use of carbon-capturing technologies) by 2075.
If the world fails to act, the researchers warn, there will be some significant and unsafe changes to our world, including rising sea levels, significant impacts on ocean temperatures and acidity, and the ability to grow crops such as rice, maize and wheat.
The White House has previously declined to clarify Trump's position.
Mr Trump had said that climate change was a hoax during his election campaign in 2016, but he has generally avoided taking a clear stance on the issue since taking office. Rubio acknowledged temperature rises and swelling seas but argued inaccurately that "many scientists would debate the percentage of what is attributable to man versus normal fluctuations".
It sparked speculation that the former reality television star still believed climate change was invented. We'll keep you posted with all of the latest political news surrounding President Trump and his policies on climate change.
