“Now is the time to act on climate change.”

Variations on this sentiment have been frequently repeated throughout the 21st century by all kinds of leaders: Ban Ki-Moon, UN secretary-general; Jorma Korhonen, director general of external economic relations for Finland’s foreign affairs ministry; Nasa climatologist James Hansen; the Intergovernmental Panel on Climate Change; environmental nonprofits, such as World Wildlife Fund for Nature; Jasmine Huggins, policy and advocacy officer for Haiti at hunger and poverty nonprofit Church World Service; and executives, such as Jean-Pascal Tricoire, CEO of Schneider Electric.
