While lead negotiators at the Lima climate talks hailed a hard-fought climate agreement forged over the weekend, many critics say the accord does not go nearly far enough in forcing meaningful reductions in global greenhouse gas emissions. The accord marks the first time that all nations, rich and poor, have agreed to submit plans outlining how they will reduce carbon emissions. But the Lima Accord, intended to lay the groundwork for crucial climate talks next December in Paris, does not include legally binding requirements that countries cut their emissions by a specific amount. As the negotiations dragged on for an additional two days, an agreement was reached on Sunday only after China and other nations killed a provision that would have required all countries to submit readily comparable emissions data. Still, many climate officials praised the plan because it marked the first time that nearly 200 nations agreed to submit blueprints on how they plan to reduce greenhouse gases.
