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.

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.

Climate pause takes a wallop as IPCC comes out swinging 27 September 2013Last updated at 15:02 ET Ker-pow! The IPCC was sheepish on the pause in its draft report; but more bullish in the final publication In the heady atmosphere of the old Munich brewery where they had been ensconced for the past four days, there was a real sense of determination among the scientists of the Intergovernmental Panel on Climate Change (IPCC). 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.

Apps That Challenge Kids to Solve Environmental Issues By Tanner Higgin, Graphite Environmental education for most adults used to mean learning a little bit about recycling and planting some trees on Arbor Day. We didn’t delve into ecology as much as we skimmed the surface. But things have gotten more complex since then, and the topic of climate change has brought environmental education to the forefront. Emissions of CO2 driving rapid oceans 'acid trip' 17 November 2013Last updated at 18:13 ET By Matt McGrath Environment correspondent, BBC News Corals all over the world are threatened by rising rates of acidification in the oceans The world's oceans are becoming acidic at an "unprecedented rate" and may be souring more rapidly than at any time in the past 300 million years. In their strongest statement yet on the issue, scientists say acidification could increase by 170% by 2100.

Carbon dioxide levels hit historic high - Americas The level of carbon dioxide in the atmosphere has broken above a symbolic threshold, 400 parts per million (ppm), for the first time, US monitors have said, indicating a record level for greenhouse gases. Climate scientists said the findings should serve as a call for action to reverse the damage caused by human activities and heavy use of polluting fossil fuels. The Earth has not had these levels of carbon dioxide in millions of years, said Bob Ward, policy and communications director at the Grantham Research Institute on Climate Change and the Environment at London School of Economics and Political Science. "We are creating a prehistoric climate in which human societies will face huge and potentially catastrophic risks," Ward said.

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. These issues affect everyone in the world but the good news is that everyone in the world can be a part of the solution if they so desire. Make sure that you do your part by swotting up on climate change and global warming, and committing yourself to a lifestyle that reduces these concerns. What are Climate Change and Global Warming? Climate Change, Deforestation, Biomes and Ocean Currents, Plankton, Endangered Species - Earth Web Site Click for more detail Thermohaline Change Evidence is growing that the thermohaline current may be slowed or stopped by cold fresh water inputs to the Arctic and North Atlantic oceans. This could occur if global warming is sufficient to cause large scale melting of arctic sea ice and the Greenland ice sheet. Such a change in the current may be gradual (over centuries) or very rapid (over a few years). Either would cause planet wide changes in climate. This effect may be part of what starts and stops the ice ages.
