Human World PopulationThe United Nations Population Division supplies a World Population Database.US Census Bureau World Population Info includes Historical World Population Estimates going back to the year 10,000 B.C. Negative Population Growth was trying to deal with the real problem, not just the symptoms-- but their website, as of this writing, is dead. Climate Change & Global WarmingThe Global Change Master Directory provides access to over 5200 datasets on global change.NOAA provides articles on Global Warming. Climate Change FAQs froom The Nature Conservancy. Environment News & Biosphere Articles SearchEnvironmental News Network is a comprehensive environment portal, with environmental news, articles, daily feature stories, forums, live chats, and more. You can search their archive of over 40,000 articles dating back to Jan. 1, 1997 from here:Earth ObservationTwo satellites, Terra, launched on December 18, 1999, & Aqua, launched on May 4, 2002, are the flagships in NASA's Earth Observing System. Terra & Aqua both carry a number of instruments, including the Moderate-Resolution Imaging Spectroradiometer or MODIS, which measures light in 36 frequency bands at three different resolutions. Another important instrument is the Multi-angle Imaging SpectroRadiometer, or MISR. Viewing the Earth at nine widely spaced angles, MISR collects global images with high spatial detail in four colors at every angle, enabling more accurate estimates of the total amount of sunlight reflected by Earth's diverse environments.At the MODIS Rapid Response System Photo Gallery you can browse through or search for MODIS photos of fires, dust storms, icebergs, typhoons, and other major earthly events. Look here for the latest NASA Earth Images and here for climate change data from NASA's Earth Missions. NASA's Earth Observatory is another, somewhat less technical interface to satellite imagery of the earth and its climate, and includes The Blue Marble, "the most detailed true-color image of the entire Earth to date," with a variety of high resolution versions you can download, free for public use. The US Geological Survey's Satellite Images of Environmental Change from 1972 to present. NASA's Visible Earth is "a consistently updated, central point of access to the superset of NASA's Earth science-related images, animations, and data visualizations. These images are considered to be public domain and, as such, are freely available to the interested public-at-large, the media, scientists, and educators for re-use and/or re-publication." Water Resources, Rainwater, Acid RainUSGS provides stream flow data and other information about US Water Resources (including acid rain deposition) displayed in frequently updated maps, from a decade ago to today.The National Atmospheric Deposition Program (Acid Rain) has data from over 200 monitoring sites diplayed in annual maps. Energy Consumption, Pollution, RecyclingEPA My Environment provides information about pollution problems and toxic chemicals in your area.The Lifecycle Assessment Calculator figures metals, toxics, and energy input, and greenhouse gases output of cars, restaurants, roads, etc. over their lifetime. The Global Recycling Network has waste commodity and stock prices, and a Recycling Career Center. Recycler's World provides recycling information and links. Environmental OrganizationsEnvironmental Defense FundThe direct activism of Greenpeace has gotten them on the front pages more than any other environmental organization.

(Jul 3, 2008) "Extinction risks for natural populations of endangered species are likely being underestimated by as much as 100-fold because of a mathematical 'misdiagnosis,' according to a new study led by a University of Colorado at Boulder researcher." Science Daily storyNuclear Power & Nuclear WasteThe US Nuclear Regulatory Commission recently redesigned their website, removing some of their information presumably due to terrorism concerns. The site still has info on reporting a safety concerns, radiation protection, employment at the NRC, contracting with the NRC, and FOIA requests. They also have nuclear FAQs pages, and info about specific reactors (some of this is what appears to have been removed), safety and security concerns, and more.The official word on Radioactive Waste from the US Nuclear Regulatory Commission. Information on the US Department of Energy cleanup of nuclear weapons production facilities run by the Department of Defense, which is costing about $6 billion a year.
