Melting glaciers and the loss of seasonal snow pose significant risks to the stability of water resources in South Asia. The 55,000 glaciers in the Himalaya, Karakoram, and Hindu Kush (HKHK) mountain ranges...
Globally, cities are the source of over 70 percent of the world's greenhouse gas emissions. Cities are also the engines of the global economy, concentrating more than half the world’s population, and they...

Improving global cooking conditions is a primary focus of Sustainable Development Goal (SDG) 7, which aims to ‘ensure access to affordable, reliable, sustainable, and modern energy for all.’ Compared to...
Access to reliable electricity is fundamental to economic growth, improvements in health and livelihoods, and the development of societies. Around the world nearly one billion people are still living without...
Chronic underheating is commonplace among poor households in cold-climate regions of developing countries beyond the reach of district heating and gas-distribution networks. Until fuel switching is possible...
The practice of burning unwanted vegetation to prepare land for sowing crops or other farming activities is a worldwide and long-standing practice. Its tenacity, despite its harmful consequences for air...
The primary purpose of the Global Environment Facility (GEF) is to generate global environmental benefit. The essential path for achieving this goal is the financial support of projects whose completion...
With data from the nearly 6,000 households in the Nepal Living Standards Survey of 2010–11, this paper finds that the mean reduction in household firewood collection associated with use of a biogas plant...
This paper uses a randomized experimental design and real-time electronic stove use monitors to evaluate the frequency with which villagers use improved biomass-burning Mirt injera cookstoves in rural...
This report aims looks at efforts to control black carbon emissions from diesel-based transportation in developing countries. It presents a summary of emissions control approaches from developed countries...
The growing interest in clean cooking, with its potential benefits for human health, environmental protection, and climate change, has prompted development specialists to reconsider the quality and performance...
A 2013 scientific assessment of black carbon emissions and impacts found that black carbon is second to carbon dioxide in terms of its climate forcing. High concentrations of black carbon in the atmosphere...
Diesel gensets contribute to emissions of fine particulate matter (PM), including black carbon, which derives from the incomplete combustion of diesel (as occurs in many diesel generating sets or gensets)...
Climate change is happening faster and in a dramatically more visible way in the Earth's cryosphere than anywhere else on earth. Cryosphere is defined as elements of the Earth system containing water in...

相较于地球上的其他地方,气候变化在冰雪圈以更快的速度和引人注目地可见方式发生着。冰雪圈是指地球系统水以冰冻状态存在的部分。不管是北冰洋、南极洲、喜马拉雅山或其他山区地区都是如此:气温以相当于或高于全球平均速度两倍的速度上升。本报告总结在安第斯山脉地区、南极洲、北极、东非高地和喜马拉雅山区等五个主要冰雪圈地区已被观测到的变化。报告随后对解决甲烷和黑碳的影响提供了一个科学的评估,以减少全球环境和人类社会、尤其是最弱势人口的风险。第二章基于包括第五个政府间气候变化专门委员会的评估报告(2013)的最新文献对发生在5个地区的变化做了综合评估。第三章叙述了污染和气候关系,以及甲烷与黑碳如何影响气候、尤其是冰雪圈的知识。第四章介绍了作为本研究一部分的建模工作的背景和方法,建立广泛的联合国环境规划署/世界气象组织黑碳和臭氧综合评估(2010)。第五章展示了5个主要冰雪圈地区和全球的新模型对健康、作物影响和气候的建模结果。最后,第六章探讨了从建模结果中得到的启示和冰雪圈地区的未来发展方向。
