International climate talks concluded today without agreement on regulating carbon markets. Representatives of nearly 200 nations who'd gathered in Madrid for two weeks did concur on urging greater "ambition" on cutting emissions that cause global warming, as well as helping poor nations hit by climate-related flooding, fires and other conditions. But they couldn't come to terms on how countries and businesses would be able to offset each others' emissions , believed key to controlling atmospheric carbon.
What now? The delegates agreed to come up with carbon market schemes in time for the next climate conference, a year from now in Glasgow, Scotland.
