In 1992, more than 150 nations agreed at a meeting in Rio de Janeiro to take steps to stabilize greenhouse gases at a level that would “prevent dangerous anthropogenic interference with the climate system” — United Nations-speak for global warming.
Many follow-up meetings have been held since then, with little to show for them. Emissions of greenhouse gases have steadily risen, as have atmospheric temperatures, while the consequences of unchecked warming — persistent droughts, melting glaciers and ice caps, dying corals, a slow but inexorable sea level rise — have become ever more pronounced.
On Monday, in Paris, the signatories to the Rio treaty (now 196), will try once again to fashion an international climate change agreement that might actually slow, then reduce, emissions and prevent the world from tipping over into full-scale catastrophe late in this century. As with other climate meetings, notably Kyoto in 1997 and Copenhagen in 2009, Paris is being advertised as a watershed event — “our last hope,” in the words of Fatih Birol, the new director of the International Energy Agency. As President François Hollande of France put it recently, “We are duty-bound to succeed.”
