At COP 21 (the 21st session of the Conference of the Parties) in Paris, climate delegates are drafting a new global agreement to reduce carbon emissions worldwide.
Meanwhile, artists have literally taken to the streets to raise awareness about climate change.
Here are a few standout public art interventions:
Shepard Fairey unveiled “Earth Crisis,” a giant sphere suspended between the first and second floor of the Eiffel Tower, visible to the public on November 20 to 26.
The Standing March
French artist JR and American filmmaker Darren Aronofsky teamed up on a series of video projections, "The Standing March," featuring the faces of 500 people as a call to action for the world to unite against global warming. British group 3D (Massive Attack) composed the accompanying original soundtrack. The projections debuted at the Assemblée Nationale on November 29 and traveled around the city, to sites like the Pantheon, Musée d'Orsay and the Louvre, through December 7.
For security reasons following the recent terrorist attacks in Paris, public marches were forbidden, which made these virtual crowds even more striking and poignant.
Guerilla artists from the U.K.-based group Brandalism, installed about 600 unauthorized artworks in public advertising spaces across Paris, critiquing the corporate sponsors of the COP21 climate talks.
The spoof ads were created by more than 80 artists from 19 countries, and they targeted companies like AirFrance, Volkswagen, Dow Chemicals and other major greenhouse gas emitters.
The group said in a statement that the subversive ads aimed to "highlight the links between advertising, consumerism, fossil fuel dependence and climate change."
1 Heart 1 Tree
The red, white and blue lights that shone on the Eiffel Tower after the recent terrorist attacks were replaced at COP21 by bright green projections of "virtual trees," designed by Belgian-Tunisian artist Naziha Mestaoui.
The 1 Heart 1 Tree project allowed participants to contribute to the public art installation by buying a "virtual tree," created through the project’s website or a mobile app. The purchase also supported real tree plantings for reforestation programs in Brazil, Peru, Senegal, Kenya, France, India and Australia.
Once someone buys a tree, their digital creation “grows” for a few seconds in a visual display on the Eiffel Tower, including the buyer's message or name.
Olafur Eliasson and Minik Rosing arranged 12 blocks (80 tonnes) of ice in a clock formation on the Place du Panthéon, where they will melt away during the climate conference. You can see passersby press their ears to the ice, listening to it crackle and split and trickle into nothing. The ice was harvested from free-floating icebergs in a fjord outside Nuuk, Greenland. The project is part of the Artists4ParisClimate2015 initiative.
