World population World population estimates from 1800 to 2100, based on "high", "medium" and "low" United Nations projections in 2010 (colored red, orange and green) and US Census Bureau historical estimates (in black). Actual recorded population figures are colored in blue. According to the highest estimate, the world population may rise to 16 billion by 2100; according to the lowest estimate, it may decline to 6 billion. The world population is the total number of living humans on Earth. The world population has continuously grown since the end of the Great Famine and the Black Death in 1350, when it was near 370 million.[6] The fastest growth rates – global population increases above 1.8% per year – occurred briefly during the 1950s, and for longer during the 1960s and 1970s. Population by region[edit] Six of Earth's seven continents are permanently inhabited on a large scale.

Chemical Weapons Stockpile and Destruction Sites Map and Photos The following map and photos depict the locations of what remains of the U.S. chemical weapons stockpile and the facilities being constructed to complete the destruction of remaining chemical agents. According to a press release from the Department of Defense’s Assembled Chemical Weapons Alternatives program office, the U.S. had destroyed “nearly 90 percent of the chemical weapons stockpile” in advance of the extended Chemical Weapons Convention deadline of April 29, 2012. Though chemical weapons were originally stored at eight continental U.S. Army military installations, only two facilities remain active.

Life expectancy history: Public health and medical advances that lead to long lives. Photo courtesy of Kentucky Cabinet for Health and Family Services The most important difference between the world today and 150 years ago isn’t airplane flight or nuclear weapons or the Internet. It’s lifespan. We used to live 35 or 40 years on average in the United States, but now we live almost 80. We used to get one life. Laura Helmuth is Slate's science and health editor. You may well be living your second life already. Adrian’s lung spontaneously collapsed when he was 18.Becky had an ectopic pregnancy that caused massive internal bleeding.Carl had St. After a while, these not-dead-yet stories start to sound sort of absurd, like a giddy, hooray-for-modernity response to The Gashleycrumb Tinies. M is for Maud who was swept out to sea … then brought back to shore by a lifeguard and resuscitated by emergency medical technicians. O is for Olive run through with an awl … but saved during a four-hour emergency surgery to repair her collapsed lung. Now we’d like to hear your stories.

Zodiac Division of the Ecliptic into ArcsDwazdahan The ecliptic strip or belt in the celestial sphere (in whose confines the Sun’s describes a path) which is commonly divided into 360 degrees. The ecliptic is further divided into twelve arcs known in Middle Persian Zoroastrian texts as dwazdah-an "the twelve ones" each 30° long. Each arc contains a named group of stars called a named constellation or group of prominent stars. Zodiac - Its Etymology It is commonly understood that the term zodiac derives from Latin "zōdiacus" which means a circuit. Constellations Dwazdah-Akhtaran The Zodiac consists of twelve constellations, the Dwazdah-Akhtaran, a discernible group of stars that from a pattern.There are 88 constellations. Varak (Aries) When the Zoroastrian zodiac was last assembled, the first degree of Varak the ram (known in the West as Aries) marked the start of vernal or spring equinox, the first day of spring in the northern hemisphere.

Wind Map An invisible, ancient source of energy surrounds us—energy that powered the first explorations of the world, and that may be a key to the future. This map shows you the delicate tracery of wind flowing over the US. The wind map is a personal art project, not associated with any company. We've done our best to make this as accurate as possible, but can't make any guarantees about the correctness of the data or our software. Please do not use the map or its data to fly a plane, sail a boat, or fight wildfires :-) If the map is missing or seems slow, we recommend the latest Chrome browser. Surface wind data comes from the National Digital Forecast Database. If you're looking for a weather map, or just want more detail on the weather today, see these more traditional maps of temperature and wind.

Interactive game of death in history: How would you have died in the past? Please read the rest of Laura Helmuth's series on longevity. The main reason life was so different 100, 200, or 300 years ago than it is today is that death was so different. People died young—in infancy or childhood, mostly—and they died miserably of communicable diseases. We barely remember the names of some of these diseases today, but they were once the most dreaded words in the English language: consumption (tuberculosis), pleurisy (swelling), putrid fever (typhus), quinsy (tonsillitis), and iliac passion (a particularly violent gastrointestinal disorder). Life expectancy has doubled in just the past several generations, and that’s largely because public health efforts and modern medicine have vanquished the diseases of the past. If you’ve ever fantasized about traveling back in time, this game is for you. Spin the wheel as many times as you like—you get infinite reincarnations.

Members and partners In a Supplementary Protocol to the Convention on the OECD of 14 December 1960, the signatory countries agreed that the European Commission should take part in the work of the OECD. European Commission representatives work alongside Members in the preparation of texts and participate in discussions on the OECD’s work programme and strategies, and are involved in the work of the entire Organisation and its different bodies. While the European Commission’s participation goes well beyond that of an observer, it does not have the right to vote on decisions or recommendations presented before Council for adoption.

Air pollution monitoring stations face closure as government looks to cut costs | Environment Up to 600 stations for monitoring air pollution across England could be shut down under new government plans to save money by cutting regulations. Ministers want to remove obligations on local authorities to assess air quality in their areas, resulting in less monitoring. But environmental campaigners are accusing them of trying to hide one of the country's biggest public health problems. Government advisers have estimated that one type of pollutant – miniscule particles from diesel engines, fossil fuel power stations and other sources – is killing 29,000 people a year in the UK, and costing health services about £16bn. But European air pollution limits meant to protect health are being breached in urban areas across the country, with the highest levels in London. But now Defra has launched a six-week consultation, due to close on 30 August, proposing a radical overhaul of the local air quality management regime that has been in place since 1997.

Cyberspace and the Dream of Tielhard de Chardin Progressive Catholics have long cherished Teilhard de Chardin and his unique and mystical vision, and for those of us who have only recently discovered the New Cosmology, his discovery is as great an epiphany as the encountering of Hildegard, Julian of Norwich, or any of the other mystics who testify to Divine immanence. Teilhard was a man possessed of rare vision who was capable of remythologizing his faith to fit the "facts" that his scientific studies convinced him of. His was not a God "out there" who disapproved of humans hypothesizing about or even tampering with the Creation. His God was an organic entity who lived and breathed the life and breath of the Creation, a Creator who was simultaneously giving birth to and being born from the magnificent organism of the universe. Chardin was not a psychologist, nor even a philosopher in the usual sense. The evolutionary ascent of human beings occurs, according to Chardin's theory, in two stages of what he calls "planetization."
