A climate pact without emission-reduction commitments from emerging nations will be a hard sell to the U.S. public, Trigg Talley, the country’s climate envoy, told delegates at the United Nations-led talks. Brazil’s envoy Jose Domingos Miguez called on developed nations to act now on global warming or “we are going to suffer the consequences.”
