As the Paris climate negotiations closed Saturday, you heard a great deal of hope and optimism as well as congratulations for vision and progress emanating from COP21. Indeed, important commitments have been made – but they’re pledges, not actions, and they don’t reverse the adverse climate change underway.
Which is why adaptation is more important than ever.
Among conference influencers, I heard many reasons against adaptation. Such projects aren’t bankable, contended the head of Regions20, a United Nations investor collaboration. Mitigation is more interesting, maintained a global nonprofit agriculture sustainability advocate. And from the United Nation’s adaptation chief: Lessening greenhouse gases is the only thing insurance companies should spend money on.
But these leaders, among the most active climate actors at the historic conference, postpone adaptation at their peril – and so does the rest of the world. Consider the warnings that sound so loudly from Stanford and Berkeley calculations: Global incomes could decline 23 percent by 2100 relative to a world without climate change. And by 2030, annual costs of adaptation could be $150-300 billion a year, by the UN’s own estimate.
