Alain Robert is known as the "French Spider-Man." For years, the human spider has scaled structures like buildings and cliff faces with his bare hands.
On Friday, his hands took him to the top of Alto Tower in Paris, insideedition.com reported.
"I would like for governments of the whole world to hear this message and invest more effort to fight climate change," he told reporters about his reason for the climb.
It took Alain 50 minutes to reach his climbing goal, but it's going to take a little longer for his environmental objectives to be achieved.
In Noveber, the UN Climate Change Conference will meet in Scotland.
Robert, 60, in early September also completed a climb of the façade of the Total Energies Tower in La Defense, Paris, which rises at 187 metres (613 feet).
He is famous for his free solo climbing, scaling skyscrapers using no climbing equipment except for a small bag of chalk and a pair of climbing shoes.
Robert has climbed landmarks including the Burj Khalifa in Dubai, Eiffel and Montparnasse towers in Paris, the Sydney Opera House as well as other of the world's tallest skyscrapers.
