Home Introducing the ultimate climate change FAQ | Environment A scientist on Mount Erebus, Ross Island, Antarctica. Photograph: George Steinmetz/Corbis Take one arcane and evolving scientific discipline. Add the future of energy security, economics and geopolitics. Throw in a handful of ideological baggage from across the political spectrum, season with ulterior motives, and simmer for 20 years. Given this unique recipe, it's not surprising that the climate change debate has thrown up more than its fair share of confusion, misinformation and divisiveness. Is the science surrounding man-made warming basically settled, or is there ongoing debate among climate scientists? These and countless other important questions have been explored in depth in journals, reports and books, but they are rarely dealt with in an accessible way. It's in this context that environmentguardian.co.uk is launching the Ultimate Climate Change FAQ. We'd also like your suggestions for what questions to answer next, of course.
WWF: Climate change Carbon dioxide, or CO2, is the most significant of the gases in our atmosphere which keep the Earth warm. 4 billion years ago its concentration in the atmosphere was much higher than today - 80% compared to today's 0.03%. But most of it was removed through photosynthesis over time. All this carbon dioxide became locked in organisms and then minerals such as oil, coal and petroleum inside the Earth's crust. A natural carbon dioxide cycle keeps the amount of CO2 in our atmosphere in balance. The amount of naturally produced CO2 is almost perfectly balanced by the amount naturally removed.
Green versus gray: Nature's solutions to infrastructure demands - Opinion For almost a century, New York City has drawn its drinking water from the Catskill Mountains, more than 100 miles (161km) to the north. In April of 2007, the Environmental Protection Agency (EPA) announced the results of a several-year review of the city's ongoing programme to maintain clean drinking water supplies with forest and open space conservation in the Catskills rather than the construction of filtration plants. The results were encouraging. The EPA concluded that as long as the city agreed to set aside $300m over the next 10 years to acquire land and restrain upstate development that causes runoff and pollution, the agency would exempt New York from having to build an $8bn filtration plant. The Catskills aqueduct has been held up as the quintessential example of green infrastructure trumping gray and has prompted cities worldwide to consider alternative solutions to the infrastructure demands of the 21st century. Many of these assets even appreciate in value over time. 1. 2.

Harvest Boon Villa Welpeloo in Enschede, the Netherlands, doesn't look like a recycled building. Its austere lines and spacious interior have nothing of the junkyard aesthetic about them. Yet despite appearances, it's reused to the bones. To accomplish this, architects Jan Jongert and Jeroen Bergsma of 2012Architects reversed the typical order of the design process—first house, then materials—and instead began by scouting the local area for items to recycle. Villa Welpeloo was the architects' first house, designed for clients Tjibbe Knol and Ingrid Blans. "Reused materials account for 60 percent of the structure," says Jongert. The architects came to the idea of superuse architecture when they were student at Delft University of Technology. So when they received the commission for Villa Welpeloo (Jongert and Blans have been friends since Jongert was eight), step one was to create a "harvest map," an inventory of possible suppliers from within a nine-mile radius of the building site.
Mongolian Herders' Perceptions of Climate Change We are interviewing nomadic herders about their perception of recent climate changes that are occurring in northern Mongolia. Most of Mongolia is a high-altitude grassland, or steppe, that has been grazed by the animals of nomadic herders for more than 4,000 years. Herd sizes were small, and had little effect on the steppe, which they shared with wildlife grazers, including millions of Mongolian gazelle. The herders we are interviewing live in two areas of northern Mongolia — in tributary valleys entering Lake Hovsgol, a large, ancient lake in the extreme northern part, and in Hentii, 500 miles to the east, an area famous as the birthplace of the great ruler Genghis Khan. We interviewed more than 100 herder families in 2009 and 2010 using a series of questions that asked each herder to give us his perspective on different aspects of the climate — for example, “Have the seasons changed?”
Eco Friendly Kids: Global Warming Author: Beth Morrisey MLIS - Updated: 16 November 2012| Comment Many people consider climate change and global warming the greatest environmental challenges facing the world today. What are Climate Change and Global Warming? Climate change and global warming are pretty much exactly what they say. What Causes Climate Change and Global Warming? While politicians around the world wrangle about the causes of climate change and global warming, scientists know that when greenhouse gases such as carbon dioxide and methane are released into the atmosphere they contribute to the problem. How are Climate Change and Global Warming Affecting the UK? What Can We Do to Limit Climate Change and Global Warming? The UK government has already taken a big step by agreeing to, and carrying through on, reducing greenhouse gas emission levels but we still have a target of a 20% reduction by the year 2010. At home, turn off lights and unplug electrical equipment when not in use. You might also like... Title: Notify:
The Secret of the Seven Sisters - Oil cartel On August 28, 1928, in the Scottish highlands, began the secret story of oil. Three men had an appointment at Achnacarry Castle - a Dutchman, an American and an Englishman. The Dutchman was Henry Deterding, a man nicknamed the Napoleon of Oil, having exploited a find in Sumatra. He joined forces with a rich ship owner and painted Shell salesman and together the two men founded Royal Dutch Shell. The American was Walter C. Teagle and he represents the Standard Oil Company, founded by John D. The Englishman, Sir John Cadman, was the director of the Anglo-Persian oil Company, soon to become BP. The new automobile industry was developing fast, and the Ford T was selling by the million. That August night, the three men decided to stop fighting and to start sharing out the world's oil. Four others soon joined them, and they came to be known as the Seven Sisters - the biggest oil companies in the world. In the first episode, we travel across the Middle East, through both time and space.
What is climate change? Media playback is unsupported on your device BBC News looks at what we know and don't know about the Earth's changing climate. What is climate change? The planet's climate has constantly been changing over geological time. The global average temperature today is about 15C, though geological evidence suggests it has been much higher and lower in the past. However, the current period of warming is occurring more rapidly than many past events. What is the "greenhouse effect"? The greenhouse effect refers to the way the Earth's atmosphere traps some of the energy from the Sun. The energy that radiates back down to the planet heats both the lower atmosphere and the surface. Scientists believe we are adding to the natural greenhouse effect with gases released from industry and agriculture (known as emissions), trapping more energy and increasing the temperature. Most man-made emissions of CO2 are through the burning of fossil fuels, as well as through cutting down carbon-absorbing forests.
Road train technology can drive your car for you - tech - 18 January 2011 Video: Road train drives your car for you Letting drivers read a book, surf the net or possibly even have a snooze while behind the wheel may not sound like the best way to improve road safety. Yet that's precisely the aim of an automatic driving system that has just been road-tested for the first time in Sweden. By linking cars together into road trains or "platoons" to form semi-autonomous convoys under the control of a professional lead driver, the hope is that average road speeds can be reduced, improving fuel consumption and cutting congestion. In a test performed late last month, Volvo, one of the partners of the Safe Road Trains for the Environment (SARTRE) Project, showed that a single car could join a platoon, be "enslaved" by a lead truck, and then exit safely. Discussions are now under way to carry out tests on public roads in Spain next year. Your sensors are mine now Would you trust it?
