US presidential candidate Donald Trump is well known for his outspoken views, to say the least. But what does he have to say when it comes to science?

We decided to take a look at some of the Republican nominee’s tweets on matters ranging from asbestos to Ebola. Read on to see how they stack up against the evidence.

Not only are wind farms disgusting looking, but even worse they are bad for people’s health http://t.co/2G8YrOUZ (cont) http://t.co/NujHgnXU — Donald J. Trump (@realDonaldTrump) April 23, 2012 Advertisement

In fact, more than 25 reviews of the scientific literature have failed to find convincing evidence for harm caused by wind farms.

Remember, new “environment friendly” lightbulbs can cause cancer. Be careful– the idiots who came up with this stuff don’t care. — Donald J. Trump (@realDonaldTrump) October 17, 2012

Energy-saving bulbs can indeed give off a small amount of UV radiation – but even up close, it’s no more than you would receive standing in direct sunlight.

The U.S. must immediately stop all flights from EBOLA infected countries or the plague will start and spread inside our “borders.” Act fast! — Donald J. Trump (@realDonaldTrump) August 2, 2014



US medical experts spoke out against a travel ban during the Ebola outbreak, arguing that suspending direct flights would not only hamper relief efforts, but make controlling and monitoring the flow of people to and from the region even more difficult.

.@dubephnx If we didn’t remove incredibly powerful fire retardant asbestos & replace it with junk that doesn’t (cont) http://t.co/d10u18dh — Donald J. Trump (@realDonaldTrump) October 17, 2012



Inadequate fireproofing was blamed in part for allowing the World Trade Centres to burn, leading to their eventual collapse – but asbestos was never used in the impact zone of either tower.

Healthy young child goes to doctor, gets pumped with massive shot of many vaccines, doesn’t feel good and changes – AUTISM. Many such cases! — Donald J. Trump (@realDonaldTrump) March 28, 2014



Not only has the original study linking the MMR vaccine to autism been retracted, multiple follow up studies have failed to demonstrate any link between vaccines and autism.

The concept of global warming was created by and for the Chinese in order to make U.S. manufacturing non-competitive. — Donald J. Trump (@realDonaldTrump) November 6, 2012



In fact, 2015 was the hottest year on record, and the latest report shows the broad extent of other records and near-records set last year, undoubtedly due to changes arising from human activity.

As for Hillary Clinton, her stance on science is just what you’d expect from a person of her education and experience: she is a strong supporter.

Amazingly this statement was the most controversial in her speech on July 28 accepting the Democrat nomination. She followed it with: “I believe that climate change is real and that we can save our planet while creating millions of good-paying clean energy jobs.”

On climate change, Clinton says she will uphold the Paris climate conference pledge to cut carbon emissions by up to 30 per cent by 2025. She has also said she will promote renewable energy with a $60 billion Clean Energy Challenge. In the past Clinton has supported stem cell research.

We’ve looked for anything similar to Trump’s outbursts on Twitter, but her science credentials are looking pretty solid.
