However, the amount of C-14 has not been rising steadily as Cook maintains; instead, it has fluctuated up and down over the past ten thousand years. From radiocarbon dates taken from bristlecone pines.
There are two ways of dating wood from bristlecone pines: one can count rings or one can radiocarbon-date the wood.
Living organisms are constantly incorporating this C-14 into their bodies along with other carbon isotopes.
When the organisms die, they stop incorporating new C-14, and the old C-14 starts to decay back into N-14 by emitting beta particles.
But only looking at carbon dioxide emissions doesn't give us the total for all greenhouse gases.
So we'll have to wait until the UNFCCC publishes the results of global greenhouse gasses collated data before we can draw any firm conclusions about meeting the Kyoto agreements.
A reduction in global greenhouse gas emissions is not only the goal of environmentalists but also of pretty much every government in the world.
Currently 192 countries have adopted the Kyoto protocol.
Kieth and Anderson show considerable evidence that the mussels acquired much of their carbon from the limestone of the waters they lived in and from some very old humus as well.If we extrapolate as far back as ten thousand years ago, we find the atmosphere would not have had any C-14 in it at all.If they are right, this means all C-14 ages greater than two or three thousand years need to be lowered drastically and that the earth can be no older than ten thousand years. Answer: Yes, Cook is right that C-14 is forming today faster than it's decaying.World carbon dioxide emissions are one way of measuring a country's economic growth too.And the latest figures - published by the respected Energy Information Administration - show CO2 emissions from energy consumption - the vast majority of Carbon Dioxide produced.This is only available up to 2008.• the International Energy Agency (IEA) has global carbon emissions data up to 2008 But what can we say about this data and how close we are to the collective targets in the Kyoto agreement?The Kyoto protocol target emission does not include, but this EIA data does.You can't tell this from the notes on the data, but the EIA confirmed to us this was the case.We can determine what the so called 'bunker fuels' are from the data here.The older an organism's remains are, the less beta radiation it emits because its C-14 is steadily dwindling at a predictable rate.So, if we measure the rate of beta decay in an organic sample, we can calculate how old the sample is. Question: Kieth and Anderson radiocarbon-dated the shell of a living freshwater mussel and obtained an age of over two thousand years.
