On Saturday, climate activists in Spain stuck their hands on famous paintings by Francisco de Goya at the Prado Museum in Madrid.
A video posted on the Twitter account of campaign group Futuro Vegetal showed a docent asking visitors not to take photos of the scene.
The impacted works – from the 18th and 19th centuries – include the artists “La Maja Vestida” and “La Maja Desnuda”: The Clothed Maja and the Naked Maja.
A temperature has been painted on the wall between the two works: “+1.5 C”

“Last week the UN recognized the impossibility of keeping us below the 1.5 Celsius limit (set in the 2016 Paris climate agreement). We need to change now,” said one tweet with a photo of the couple.
The museum said his paintings were undamaged and the graffiti was painted over.
“We condemn the use of the museum as a venue for political protest of any kind,” he said.
Police and Futuro Vegetal said two people were arrested.
