If you visit Venice any time before Nov. 26 you'll get a lesson in climate change. No, the city won't be submerged under water, as some have feared, but you will see what one artist views as the cause of global warming: hands.

Artist Lorenzo Quinn's "Support" installation is a PSA against the dangers of what he views as man-made climate change and its effects on Venice. Quinn "wants to speak to the people in a clear, simple and direct way through the innocent hands of a child," he writes on his Instagram.

Why it matters: Venice is a UNESCO World Heritage site and the city, which spreads across 118 small islands, has suffered from consistently rising sea levels over the past few decades. In the 1950s, the city's historic St. Marks Square flooded 20 times per year, but now it floods around 60 times a year. And climate scientists have found that global ocean levels could increase 0.6 feet to 1.1 feet if the earth's temperature rises just two degrees celsius.
