World leaders will not attend the next round of international climate-change negotiations over concerns the talks will flounder again.
The last United Nations summit on global warming in Copenhagen, last December, ended in failure and recrimination. More than 100 heads of state turned up but failed to get any legal agreement on how to stop rising temperatures.
Now they are declining even to attend the event in Mexico next month, instead sending environment ministers and playing down the talks.
The process is dogged by a disagreement over the best way to cut carbon emissions. The goal is to cut greenhouse gases in half by 2050 in order to keep the rise in global temperatures below 2C. (© Daily Telegraph, London)
