The U.N. Environment Program released an environmental update November 1 in which it found that greenhouse gas emissions are increasing, glaciers are retreating, sea levels are rising, ocean acidity is growing, and more people than ever are living in climate vulnerable areas. The report, Keeping Track of Our Changing Environment: From Rio to Rio+20 (1992-2012), is part of the Program’s Global Environmental Outlook series, and will be released in May prior to the June U.N. Conference on Sustainable Development in Rio de Janeiro.
