When you travel, by air, car or any other form of transport you can, in theory, neutralise your emissions of carbon dioxide – the principal gas involved in man's contribution to global warming – by buying a "carbon offset."Some say they are the modern equivalent of the medieval practice of paying for indulgences.In other words, it would be better to work out a way of not sinning at all – by avoiding flying in the first place.This makes radiocarbon dating quite useful, up to a point.Error factors, plus or minus, involve hundreds of years.Principally this can be achieved by planting trees but also by doing a multitude of things, from installing solar panels or making biofuels from chip fat, to burning off major emissions of greenhouse gases from industry that would otherwise have been emitted straight into the atmosphere. At present, many companies calculate the emissions for different routes in a different way. The biggest problem is ensuring what is called "additionality."That means something that achieves genuinely additional savings to what a company would have done anyway, that is a direct result of the money you spent. But the Government has chosen to leave out a large market in credible voluntary emissions credits that are not, or cannot be, certified under the Kyoto Treaty. If the voluntary market manages to get its act together and set its own standards, there is a danger of different markets emerging – one much cheaper than the other. A further problem is that it is difficult to establish for certain whether the credits you are buying have been sold before. Environmentalists say the problems with offsetting are so major that they should be a last resort after you have reduced your emissions by other means.
Sorta confuses me is carbon dating accuracy just cause i cons dating dye my hair the colour of this person and they want to media about the death.When the plant or animal dies no further isotope is absorbed and the beta radiation emission begins to gradually reduce to half strength, after the “half-life” of the isotope; 5,730 years in the case of C14.Fortunately organic carbon is a constituent of all living material, and wood, bone, charcoal, peat, horn, and vegetable remains in soil can all be examined with sensitive Geiger counters, allowing for calculation of absolute age.Between £2 and £19 a ton of carbon, according to a recent study.There is a market for emission reduction credits so the price can increase or down.
