"I'm here to tell (President) Emmanuel Macron to come back down to earth ... by climbing with no safety net."
Robert said the pension reform, which Macron signed into law at the weekend after months of street protests, meant that, combined with a loss of income due to the COVID pandemic, he would have to keep on working, and climbing, for longer.
Under the reform, the French retirement age will gradually rise to 64 from 62.
Robert has scaled more than 150 towering structures worldwide, including Dubai's Burj Khalifa - the world's tallest building - the Eiffel Tower, and San Francisco's Golden Gate Bridge.
