Several dozen small island nations, which have banded together to raise awareness about their plight as climate change threatens their futures with rising seas and increasingly violent weather, will get a chance to voice their fears in a special session of the U.N. General Assembly on Sept. 27 and 28. The nations will once again ask larger nations to cut back on their use of fossil fuels. Meanwhile, Honduras will leap into the carbon sequestration market on September 15 when it signs an agreement with Canada to sell the carbon-absorbing capacity of its forests. Canada plans to offset some of its emissions of carbon dioxide by paying to protect forestland in Honduras. Some scientists estimate that Honduran forests absorb between 5 million and 10 million tons of carbon dioxide a year, and Honduras will try to get between $10 and $30 per ton. The country is also eyeing Germany and the U.S. as potential customers.
