Nasa is refreshingly open when it responds to requests for statements about space, climate change and even UFO sightings, and it's now taking the fight to Facebook.

In the comments on a story posted by Bill Nye about climate change, a number of users responded casting doubt on official figures from the space agency about global warming.

Nasa told users not to 'misrepresent' the agency, the evidence is 'very clearly documented' and it denied 'fudging' the numbers.

The post linked to a story about Nye offering $20,000 bets to climate change denier Marc Morano that this year will be in the top 10 hottest years on record.

The other bet was that this decade will be the hottest on record. Morana declined.

One user wrote, 'Despite Nasa confirming that fossil fuels are actually cooling the planet's temperature, and that there's more ice than in the last century in the polar caps. Yep solid science, leftards.'

Nasa's Climate Change page replied: 'Do not misrepresent Nasa. Fossil fuels are not cooling the planet.'

Another user wrote: 'Nasa loves to fudge the numbers anyway. Nasa should be irrelevant just like their space program.' In response to this, Nasa denied 'fudging' the numbers. It said that all data requires statistical adjustment to remove bias and that 'this is all very clearly documented'

In this response, Nasa wasn't specifically mentioned in the original comment but Nasa Climate Change responded addressing the comments about other planets in the solar system warming in comparison to Earth

IS CLIMATE CHANGE A CONSPIRACY THEORY? Climate change has the power to divide experts, and deniers are often referred to as conspiracy theorists as they believe the figures are part of an elaborate campaign. But the amount of people who would have been involved in keeping such a large-scale secret suggests that if they were true, they would have been exposed by someone by now. With this in mind, a physicist recently calculated how many people would have potentially worked on some of the most popular theories, and what is the likelihood of them all keeping a secret. Using this model, the truth about the moon landings being a hoax would have been exposed in three years and eight months. A climate change fraud would have been uncovered in three years nine months, a vaccination conspiracy would take three years and two months to be revealed, and a suppressed cancer cure would come to light after three years and three months.

Nasa also added a link to an official support page title: 'Why use the adjusted rather than the raw data?'

Donald Trump is a famous climate change denier and recently tweeted: 'The concept of global warming was created by and for the Chinese in order to make U.S. manufacturing non-competitive.'
