The Migros Supermarket in Eschenbach, Switzerland, sets an LED milestone by switching to 100% LED lighting throughout the entire store--in the refrigerated compartments, overhead, and accenting the selection of products on offer. This project demonstrates once again the ecological superiority of the LED technology.

A lamp, in technical usage, is a replaceable component such as an incandescent light bulb, which is designed to produce light from electricity. These components usually have a ceramic or metal base, which makes an electrical connection in the socket of a light fixture. This connection may be made with a threaded base, two metal pins, or a "bayonet mount."

Like all sciences, the study of climate change relies upon a thorough and comprehensive investigation of the data. It is the goal of Global Warming Art to make some of that data accessible to the public through a collection of figures and images that accurately highlight and describe key issues necessary to understanding our world's changing climate.

Arrhenius estimated that halving of CO2 would decrease temperatures by 4 - 5 °C and a doubling of CO2 would cause a temperature rise of 5 - 6 degrees Celsius [1]or 7 - 11 degrees Fahrenheit. Recent (2007) estimates from IPCC say this value (the Climate sensitivity) is likely to be between 2 and 4.5 degrees. What is remarkable is that Arrhenius came so close to the most recent IPCC estimate. Arrhenius expected CO2 levels to rise at a rate given by emissions in his time. Since then, industrial carbon dioxide levels have risen at a much faster rate: Arrhenius expected CO2 doubling to take about 3000 years; it is now predicted to take about a century.

Climate change: we have the power
There are pale greens and dark greens. Often they don’t see eye to eye. But there is no shortage of technologies to tackle global warming. We listen to the visionaries of change

Vertical farming is a conceptual form of agriculture done in urban high-rises. In these high-rises (variously called "farmscrapers," food such as fruit, vegetables, fish, and livestock can be raised by using greenhouse growing methods and recycled resources year-round, allowing cities of the future to become self-sufficient.
