实践中的能源管理：社区行动起来保护气候

地方环境举措国际理事会(ICLEI)城市气候保护运动与地方政府一起工作,采用综合的和战略的能源管理手段减少温室气体排放.对参加气候保护运动的43个国家的386个城市地方政府的抽样调查表明,实质性的行动已经改善了地方的能源管理并且减少了温室气体（GHG）排放.     

Lake variability: key factors controlling mercury concentrations in New York State fish

A 4year study surveyed 131 lakes across New York State beginning in 2003 to improve our understanding of mercury and gather information from previously untested waters. Our study focused on largemouth and smallmouth bass, walleye and yellow perch, common piscivorous fish shown to accumulate high mercury concentrations and species important to local fisheries. Fish from Adirondack and Catskill Forest Preserve lakes generally had higher mercury concentrations than those from lakes in other areas of the state. Variability between nearby individual lakes was observed, and could be due to differences in water chemistry, lake productivity or the abundance of wetlands in the watershed. We found the following factors impact mercury bioaccumulation: fish length, lake pH, specific conductivity, chlorophyll a, mercury concentration in the water, presence of an outlet dam and amount of contiguous wetlands.
